4 211-2 Log #CP2 Technical Committee on Chimneys, Fireplaces, and Venting Systems for Heat-Producing Appliances, Global change - make the "P" in Portland cement capitalized throughout. Portland should be capitalized as the name of the town for which the product is named Log #3 John F. Bender, Underwriters Laboratories Inc UL Publications. Underwriters Laboratories Inc., 333 Pfingsten Road, Northbrook, IL ANSI/UL 103, Standard for Factory-Built Chimneys for Residential Type and Building Heating Appliances, 2001, with revisions through June ANSI/UL 127, Standard for Factory-Built Fireplaces, 2008,Revised UL 378, Standard for Draft Equipment, ANSI/UL 959, Standard for Medium Heat Appliance Factory-Built Chimneys, 2001, with revisions through September 2006 Revised Reason: Add ANSI approval designation to ANSI/UL 959 and update referenced standards to most recent revision Log #2 Glossary of Terms Technical Advisory Committee, Revise the current definition of as follows: A field-constructed chimney of solid masonry units, bricks, stones, listed masonry chimney units, or reinforced Portland cement concrete that is lined with suitable chimney flue liners. And built in accordance...". Specific requirements for masonry chimneys should not be provided within the definition. Place the requirements in a separate section within the standard. This definition (from NFPA 54) is the preferred definition from the Glossary of Terms. Changing to this definition complies with the Glossary of Terms Project. Your technical committee has the following options: a) Adopt the preferred definition b) Modify the term to make it unique c) Request that the Standards Council reassign responsibility for the term d) Request that the standards council authorize a second definition The committee rejects the proposal because the definition was updated in the 2010 edition and the text recommended for modification no longer exists. 3

5 211-5 Log #13 Royal Edwards, Royal Edwards Technical Services, LLC Rain Cap Height. Minimum distance from the underside of an unlisted rain cap to the top of covered flues shall be the lesser dimension of the width or depth of the covered flue. Where more than one flue is covered, the lesser dimension of the highest flue shall be used. 0.7 times the long dimension of the longest covered flue. Purpose is to further refine guidance for lid height of unlisted rain caps. We often see metal or masonry lids so close above the flue termination as to inhibit the exit of the flue gases. Source: Handbook of Oil Burning (1951) page 458, figure 4. They used 0.6 as a factor but 0.7 works better when you include flues venting solid fuel appliances. Example A, one 8x8 covered flue. 8 times 0.7=5.6 rounded to 6 inches minimum cap height. Example B, If several flues were covered: 8x8, 8x12, 12x inches would be the long dimension of the longest covered flue. 12 x 0.7 =8.4 inches rounded to 8 inches. Example C. If the flues in Example B included an 8x16 flue, the longest flue would be 16 inches. 16 x 0.7 = 11.2 rounded to 11 inches. These minimums fall within what is typically available from metal cap manufacturers as well as anyone creating a masonry rain cap on a masonry chimney. The committee agrees that the rain cap height is an important issue that needs further review, but is unsure that the proposal provides the correct guidance. The committee established a task group to study the location and requirement so that clearer guidance can be developed. The committee recommends relocating the requirement to chapter 7 because the unlisted rain cap is only applicable to masonry chimneys Log #7 John F. Bender, Underwriters Laboratories Inc. Factory-built chimneys shall comply with the requirements of ANSI/UL 103, ; or ANSI/UL 959,. Reason: Add ANSI approval designation to ANSI/UL

6 211-7 Log #1 David Hanten, Clark, Inc. Add new text as follows: (6) The enclosure shall not contain or be constructed from any type of fire barrier or fire resistant (including ASTM E2336 & ASTM E136) duct wrap. Provides clarification of what can not be used for an enclosure rating on vents, chimneys and breechings; Eliminates application misconception caused by fire barrier insulation manufacturers; helps support venting manufacturer installation instructions that state not to install insulation around venting material; protects the UL listing on UL 1738 vents; protects and the ability to inspect the vent; eliminates potential dangers that may not have been tested for Rated Enclosures. Factory-built chimneys that pass through floors of buildings requiring the protection of vertical openings shall be enclosed with approved walls having a fire resistance rating of not less than 1 hour where such chimneys are located in a building less than four stories in height and not less than 2 hours where such chimneys are located in a building four or more stories in height * The enclosure shall not be constructed from duct wrap. A Duct wrap systems, such as those listed to ASTM E2336, are generally used with commercial kitchen vent systems and are not appropriate for preventing heat transfer from the chimney to nearby combustibles. In addition, factory-built chimneys are listed products that have not been tested in conjunction with duct wrap. Therefore, there is no way of determining if the duct wrap/chimney combination will provide the necessary fire resistance. If duct wrap is used within a rated enclosure, it should be properly secured and should not violate the chimney air space requirements. The committee simplified the requirement and created annex material for education of users who may not be familiar with the product Log #8 John Meredith, SaverSystems Revise text to read as follows; Add at the end of the sentence conforming to ASTM C-199 medium duty. As an interested party, I feel this clarifies more clearly the description of the type of refractory to be used and is consistent with other codes, standards and specification. The committee rejected the proposal because there are acceptable products available on the market that have not been tested to ASTM C-199. The proposed modification would effectively prohibit such materials. 5

7 211-9 Log #15 Timothy N. Seaton, Timely Construction, Inc. Add section prohibiting airtight doors without listing: 11.6 No fireplace shall be installed or modified to include tight fitting or airtight doors without design and safety testing/listing. Recent work with the new energy and green codes has seen provisions written to reduce house warm air exfiltration to require fireplaces to have tight fitting or airtight doors. While some jurisdictions require fireplace doors (ex. Washington state), these doors have not been tight fitting, allowing free makeup air passage as traditional fireplace designs have required. In fact, the tempered glass used in these doors breaks whenever the air flow is cut off. Further, the tight fitting requirement on ZC or manufactured fireplaces voids their listing under UL 127, and the unlisted masonry fireplace built to IRC and other codes creates a safety hazard as the masonry mass lacking the cooling of the makeup air now can reach much higher temperatures and ignite contiguous combustibles at the 2 distance allowed by the codes. Note: Supporting material is available for review at NFPA Headquarters. 11.4* Accessories Fireplace accessories shall be one of the following: (1) Listed and installed in accordance with the terms of their listing (2) Acceptable to the AHJ and installed as approved and in accordance with the manufacturer's installation instructions Gasketed fireplace doors for new or existing masonry fireplaces shall be listed or approved by the AHJ. The committee will continue to review this issue and has established a task group to develop annex language to provide further guidance for manufacturers and AHJs Log #10 John Meredith, SaverSystems Add after the word mortar - conforming to ASTM C-199 medium duty. As an interested party, I feel this clarifies more clearly the description of the type of refractory to be used and is consistent with other codes, standards and specifications. The committee rejected the proposal because there are acceptable products available on the market that have not been tested to ASTM C-199. The proposed modification would effectively prohibit such materials. 6

8 Log #17 Neil Giffey, German Mutual Insurance None submitted. Specific to residential garage installations. Currently no solid fuel burners are allowed by the code. Specifically due to potential flammable vapor accumulations. Conversely floor mounted open flame gas appliances are grandfathered and new installations are required to be mounted 18 in. off the floor. If the 18 in. height is accepted as a "safe" standard then I would propose an adaptation to the solid fuel code to meet this standard. Initially one might apply the same raised mounting logic as the gas code has. However, the practicality, instability, and potential for hot embers or ashes to fall from the stoking or clean out activities would negate the height benefit. Another potentially acceptable approach is to build a full height wall or separate room for the burner somewhere inside the garage area. The expense involved as well as sacrificing the usable square footage involved to meet clearance requirements makes this generally impractical for most applications. The major drawback to this system is the simple act of leaving the door open defeats the whole purpose for which it was constructed. I would submit that a compromise between these two lines of thought could utilize the theoretical advantages of both and more effectively prevent direct contact with floor level vapors. In an approvable product/system could be determined - I propose that a continuous/solid 18 in. high "wall/barrier" could be secured around the base of the burner, maintaining approved clearances based on materials used, with several problems solved. - hot embers or ashes could fall to the floor within the barrier without direct contact to vapors - minimal foot print allows maximizes the usable garage area for other uses. - no gap in the protection with no door to leave open The submitter did not provide recommended language for the committee to consider. The substantiation does not provide adequate information for the committee to consider modifications to existing language Log #16 Timothy N. Seaton, Timely Construction, Inc. Remove masonry heaters as appliance class from Chapter 12 on solid fuel burning appliances and include them under a separate chapter similar to fireplaces. Please see my information also under a separate clearance proposal for masonry heaters. Basically, the masonry construction of masonry heaters makes their issues different enough from the typical metal solid-fuel burning appliances that confusion is being created where NFPA provisions are being quoted in other codes. subsequent chapters. The result of the proposal is to move section 12.8 to a new chapter 12 and renumber all 7

9 Log #14 Timothy N. Seaton, Timely Construction, Inc. Add section covering masonry heater clearances to combustibles: Masonry Heater Clearances to Combustibles: Listed masonry heaters shall be installed with clearances according to their listing Unlisted masonry heaters shall be installed with clearances according to ASTM E1602 or this standard s rules for other unlisted solid -fuel burning appliances with the prescribed distances reduced by one half, whichever is greater (or alternatively for masonry heaters defer to TRVB H ). In the 2010 edition of NFPA 211, masonry heaters were added to NFPA 211 for the first time at my request and that of others. I have designed and installed a wide variety of these appliances for the last two decades as part of my masonry construction business, now limiting my business to their installation and that of wood fired ovens. I am a previous President of the Alliance of Masonry Heater and Oven Professionals as well as the current chair of the Hearth, Patio, and Barbecue Association s Masonry Heater Caucus and the secretary of the Masonry Heater Task Group under ASTM s Solid-Fuel Burning Appliance Subcommittee E06.54 chaired by Rick Curkeet of Intertek Labs. My comments submitted here are submitted individually and not as officially representing any of these organizations although some members also share my concerns. Masonry heaters share characteristics of both stoves and fireplaces, being constructed of masonry but of airtight construction with long smoke pathways allowing heat transfer to the masonry mass, and very hot and intense but intermittent firings, seldom more than once or twice a day. Like masonry fireplaces they are massive, weighing typically from one to multiple tons. Heat transmission is primarily through radiation from the masonry mass so that the stored energy is released very gradually compared to metal stoves. Surface temperatures are far lower than metal stoves, seldom reaching 200 degrees F anywhere except at or near the doors which are typically of metal. By regulation and defining standard the masonry heater surface temperature cannot exceed 230 degrees F anywhere except contiguous to the door (ASTM E1602 Section 3.14) Masonry heaters are built of essentially three types: 1) entirely factory manufactured and site assembled, these are typically listed; 2) site assembled from local veneer materials with factory manufactured core components (either entirely or with firebrick portions added), and 3) site assembled entirely from local materials. Construction of unlisted masonry heaters has been to ASTM E1602, Standard Guide for Construction of Solid-Fuel Burning Masonry Heaters. Listing has been to UL1482, Solid-Fuel Type Room Heaters, in which the appliance is fired continuously until its temperature stabilizes at a maximum at which point the safety clearances are set at the distance where temperatures in a contiguous wall assembly are elevated a specified temperature above ambient. This standard was designed for metal stoves and creates difficulties for testing masonry heaters and fireplaces in that firing them to reach some kind of maximum stable temperature (this is never clearly reached as in a metal stove) takes multiple days and hundreds of pounds of wood. By the time the temperature is peaking the operator must be in heat protective gear and the outcome is far beyond what any consumer can be expected to ever accomplish. At this time, however, there is no alternative in North America for heat accumulating and/or slow heat release appliances. In Europe where such appliances are traditional, the standards test to precisely the same temperature elevation at the wall but with a saner firing procedure which is in keeping with the abuse which can attained by an uninformed or careless consumer. ASTM E1602 prescribes clearances to combustibles of 8 above the heater and 4 from the sides and rear. For some in the industry this represented concerns for masonry heaters with thinner walls than those typical of masonry fireplaces (8 at the firebox and 5 beyond the firebox. Accordingly, failing in efforts to modify ASTM E1602, at their instigation the 2006 International Residential Code was modified to read: R Masonry heater clearance. Combustible materials Shall not be placed within 36 inches (914 mm) of the outside surface of a masonry heater in accordance with NFPA 211 Section 8-7 (clearances for solid-fuel-burning appliances), and the required space between the heater and combustible material shall be fully vented to permit the free flow of air around all heater surfaces. Exceptions: 8

10 1. When the masonry heater wall is at least 8 inches (203 mm) thick of solid masonry and the wall of the heat exchange channels is at least 5 inches (127 mm) thick of solid masonry, combustible materials shall not be placed within 4 inches (102 mm) of the outside surface of a masonry heater. A clearance of at least 8 inches (203 mm) shall be provided between the gas-tight capping slab of the heater and a combustible ceiling. 2. Masonry heaters tested and listed by an American National Standards Association (ANSI)-accredited laboratory to the requirements of UL1482 may be installed in accordance with the listing specifications and the manufacturer s written instructions. The apparent intent of this modification was apparently to defer masonry heater clearance to combustible distances to either a UL 1482 listing or the unlisted appliance provisions of NFPA 211 (reference now obsolete in IRC quote and needs updating) except in a narrow subset of masonry heater designs most similar to North American code built masonry fireplaces where an exception was made deferring to ASTM E1602. Problems with this: 1) Both UL 1482 and the unlisted appliance provisions of NFPA 211 were created for metal stoves developing surface temperatures several hundred degrees higher than the hottest masonry heater. A required clearance of 36 for a device built of masonry and designed not to exceed 230 degrees F is unnecessarily excessive. 2) No masonry heater was tested under UL 1482 or by any other North American standard for development of the ASTM E clearance stipulation. In fact, a masonry heater being similar to a masonry fireplace with an airtight door, several lab personnel performing UL 1482 tests have informed me that most masonry heaters, even with 8 walls at the firebox and 5 walls at the heat exchange channels, will certainly fail an UL 1482 test at 4 and require higher clearance. Masonry fireplaces with tight fitting doors fail UL 1482 at 2 clearances (see attached Curkeet letter). Tulikivi, the Finnish manufacturer of masonry heaters after UL 1482 testing of its soapstone product line (soapstone has the highest thermal conductivity of the masonry heater materials and so is most likely to achieve the highest surface temperatures) has been assigned side clearances of 14 and rear clearance of 20 (attached). Masonry heaters have a centuries old tradition in Europe and the technology used in North America has been imported from there. The standard most frequently quoted in Europe is the Austrian Federal Fire Service Association s TRVB H , Fireplaces for Solid Fuels in its Austrian Fire Prevention Provisions series (translation mine, note that the term translated fireplace is not exactly what we mean here in North America. These provisions establish 50 cm (20 ) clearance to combustible walls for metal stoves and 25 cm (10 ) for stoves built of masonry. For insulated walls with a noncombustible half hour fire rated surface these distances are reduced to 25 cm and 15 cm (6 ) for metal stoves and masonry stoves respectively. Similarly to NFPA 211, with a heat shield at 3 cm (1 ) from the wall the clearance may be reduced further, for metal stoves from combustible/noncombustible faced walls to 25 cm/15 cm similarly to a masonry stove (see attached standard). It seems to me that at present, lacking a UL listing method specifically for masonry heaters, the best method is to defer to the European experience of the product class. Notice that the distance required there for masonry construction as opposed to metal construction gives results very close to the actual UL 1482 testing for the hottest masonry heaters and that one half the distances for metal construction is a good approximation. NFPA 211 having included masonry heaters should clear this up. Note: Supporting material is available for review at NFPA Headquarters. Add text to read as follows: 12.3 Clearances to Combustibles Listed masonry heaters shall be installed with clearances according to their listing Unlisted masonry heaters shall be installed with clearances in accordance with ASTM E1602. The committee updated the proposed language to reflect the previous action of creating a new chapter 12 on masonry heaters. The committee also removed references to the Austrian standard because there is some concern about its availability for review by committee members and AHJs. The committee established a task group to develop additional language addressing exact clearance distance requirements. 9

11 Log #11 Jim Muir, Clark County Building Safety Division Revise Section 13.2 by adding an exception as follows: Exception: Chimneys and fireplaces in one- and two-family dwellings. Note: This proposal was developed by the proponent as a member of the Building Code Development Committee (BCDC) with the committee's endorsement. It is unrealistic to believe anyone will conduct annual inspections of chimneys in homes, without a cause to do so. If there was a cause, such as a carbon monoxide alarm, then an inspection would be expected. Also, see our proposal to Section requirement. Inspection of fireplaces and chimneys in one- and two- family dwellings is an important safety Log #9 John Meredith, SaverSystems "...the liner shall be either removed and replaced, repaired with a refractory mortar conforming to ASTM C-199 medium duty, or relines..." As an interested party, I feel this adds some clarity and guidance to the type of material intended for use when making repairs (such as replacement of deteriorated mortar joints) and is consistent with other codes, standards and specifications. The committee rejected the proposal because there are acceptable products available on the market that have not been tested to ASTM C-199. The proposed modification would effectively prohibit such materials Log #12 Jim Muir, Clark County Building Safety Division Add a sentence to the beginning of the section 14.1 as follows: Annual inspections shall be conducted as required by section 13.2, or as required by the AHJ. Note: This proposal was developed by the proponent as a member of the Building Code Development Committee (BCDC) with the committee's endorsement. Chapter 14 never actually requires an inspection, and never links to the requirement in section This link clarifies that inspections are required and in accordance with section This proposal also gives the AHJ authority to determine the need to inspect. Such authority is necessary for occupant safety when cause is provided, such as carbon monoxide alarm. The link to the annual inspection can be found in (1). 10
