Mendota ZC Fireplace and Insert Models DXV35DT3&4 LX, DXV45DT3&4 LX, ML47, FV41, FV46, FV33i, FV44i units produced after August 1, 2011 utilize a quick-conversion design that incorporates a pushpull tab to convert between NG and LPG configurations. Some existing stock of Fireplaces and Inserts may contain the original Round Hood SIT pilot assembly. NOTE: The new Quick-Conversion design pilot assemblies are backwards compatible and can replace the Round Hood Design Pilots. It is important to make certain that you select the proper Pilot Flame Hood design when replacing the pilot assembly. Two designs exist: 2-way Hood and 3-way Hood. Make certain you use the proper Hood Configuration for your specific model along with converting to proper gas type. ML47 & ML39 DT4 units &FV41 Arch & FV34 M = Modern Please note FV46 uses a 2 way pilot hood with 05-04-00050 pilot assembly 29

SECONDARY AIR INTAKE DAMPER The SECONDARY AIR INTAKE DAMPER is located in the convection air cavity on top of the firebox. It is accessible through the ½ slot that is located directly above the glass frame s top surface. The SECONDARY AIR INTAKE DAMPER is factory adjusted to full restriction, which is about ½ closed. Adjust this damper to fine tune the Rear Flame Height. Specifically, if the rear flame is licking the top Baffle Brick, open this damper. In most installations, the Primary Air Intake Damper adjustment will suffice. However, if the vent system restricts air flow and the rear flames appear too tall and lick the baffle brick completely, you may choose to open the Secondary Air Intake Damper to reduce the rear flame height. This feature will be of the most use in LPG applications. To adjust, use a 3/8 Open End Wrench to loosen the securing hex nut 2 turns ONLY. Use Glass Latch Tool to Slide Damper Bracket to the right towards CLOSED or to the Left towards OPEN. 37

*Please see next page for chart FV41 units & Fv46 Damper Adjustment Use a flash light to look into the convection air cavity and note the Damper Position Indicator. Hook glass latch tool in the hole at the end of the damper rod, release. Use a flashlight to inspect the damper position. The base of the damper adjustment rod has a pointer that indicates the position of the damper. This fireplace is equipped with a vent damper system that can be adjusted using the glass latch tool. Locate damper adjustment rod above the glass frame in convection chamber at the center. Note: if this fireplace s vent is terminated vertically, the damper position may be FULL OPEN or FULL CLOSED. If this fireplace s vent is terminated horizontally, DO NOT CLOSE the vent damper completely. (please see chart on following page) Adjust position of damper by judging the flame characteristics after 30 minutes of burn time. If the flames ghost off burners or if sooting occurs [in LPG units], open the vent damper FULLY and work backwards in increments to determine the correct damper position for that particular installation. You must have the unit running 20 minutes prior to set the damper properly **Always inspect damper position before installing vent pipe 38

Also applies to the M50 The table below provides a general guideline for the Exhaust Restrictor Position. Further fine tuning and adjustment may be required, as the performance of each vent system will vary. RESTRICTOR POSITION FULL OPEN 1/4 CLOSED **Note, damper could be at 12 or 6 o clock position from factory **Always inspect damper position before installing vent pipe VENTING CONFIGURATION Minimum Up and Out horizontal terminations, 1:1 vertical to horizontal run ratio, horizontal run is longer than vertical run with a horizontal termination Horizontal Terminations where the vertical run is longer than the horizontal run. 1/2 CLOSED Vertical Terminations with no horizontal runs. Vertical or Horizontal Terminations with vertical runs 3/4 CLOSED exceeding 15 feet. FULL CLOSED NEVER FULLY CLOSE THE EXHAUST RESTRICTOR 39

Mendota Proflame Training Electronic ignition pilot assemblies showing AIR to GAS mixture port ** ** You can not drill out the air opening on the SIT pilot assembly **Always ensure air to gas port is free of any debris as this will affect pilot flame performance. Suggested any time you do a service or cleaning. The primary air port can be enlarged using a 7/64 drill bit or a #36 drill bit. This will allow more air to gas and assist pilot performance. 48

SIT Group Information Bulletin Date: March 2014 Subject: Use of silicone in gas hearth appliances Extensive testing by SIT has shown that the use of silicone in gas hearth appliances and its use on the appliance vent pipe connections can negatively affect the flame sensing circuit of the intermittent pilot ignition system, with the possible result of a nuisance shut off. This affect is due to silicone particulates/vapors coating the flame sensing rod and pilot hood. This coating electrically insulates these components of the pilot assembly which inhibits the ability of the flame sensing circuit. The silicone coating can be transparent, therefore in some cases it cannot be detected by a simple visual inspection. Cleaning of the sensing electrode and pilot hood can help remove silicone deposits and restore the performance of the flame sensing circuit. The cleaning operation should be performed with an abrasive material such as steel wool or a fine metal brush. The surfaces that need to be cleaned are highlighted in blue in figures 1 and 2. After the cleaning operation is completed remove any remaining residue around the pilot. Cleaning the pilot components well will be as effective as replacing the electrode and the hood. Fig. 1 Fig. 2 49

SIT Group Information Bulletin Proflame System 24 Hour Safety Shut Off The Proflame Transmitter (Proflame 1 or Proflame 2) sends a refresh message after ~15 seconds from the last user action independently from the current mode. When in T-STAT mode (ON or SMART), the Proflame Transmitter sends a refresh message every ~10 minutes. In the manual mode OFF: If a transmission (user action) has not been detected by the receiver with in 24 hours, the system will shut off. For example, if the user turns on the appliance and leaves the home, after 24 hours the receiver will not have detected any transmissions and the system will be shut off. In the both thermostat modes Smart or ON: The unit will continue to operate unless the receiver continues to receive the same refresh message data for 24 hours. If the same data is transmitted for 24 hrs the unit will shut down. The refresh message data includes the following information: Flame level / BTU output Fan level / speed Aux enable / light Split enable / rear burner Thermostat mode (Off, On, Smart) The only data that can change automatically in Smart thermostat mode without user action is the BTU output that will be 0 (OFF) or level 1 thru 6 (6 being high). For example, if for 24 hours the flame level remains ON at the same level (1..6) the system will be shut-off. Additionally, the Smart thermostat mode will continually adjust the flame down as the room temperature gets closer to the set point. When the set point is achieved the flame will be modulated down to off. 50

Mendota Proflame Training Proflame 1 All PF1 LX units will have a receiver & remote factory installed. The silver switch (which is usually on the lower left side of the unit, depending upon model) is a IPI/CPI standing pilot switch. IPI meaning Intermittent Pilot Ignition and CPI meaning Continuous Pilot Ignition or standing pilot. *The receiver for the unit, in the OFF position will still allow a CPI pilot to light, but will not allow a IPI pilot and will prevent burners from lighting. ** (if the receiver is in the OFF position, you will still have the light bulb functions & blowers functions, provided the remote is not in a thermostatic mode) Proflame 2 All PF2 units will come standard with remote, and is required to operate the unit. The receiver is now concealed in the unit. The remote will be the only point of ON control for the fireplace. The silver switch (which is usually on the lower left side of the unit, depending upon model) is a master STOP switch, and will kill IPI pilot and burners. *Master stop switch in the OFF position will still allow a CPI pilot light, but will stop an IPI pilot from lighting and will prevent burners from lighting. **(if the master stop switch is in the OFF position, you will still have the light bulb & blowers functions, provided the remote is not in a thermostatic mode, smart or on) When a unit is left in CPI mode continuous pilot ignition it will keep the pilot going provided that wind does not blow out the pilot or AC power has not been lost to the unit. The pilot will remain lit, if batteries are plugged in to the fireplace and AC power is lost. You can keep batteries plugged in at all times provided the end user is making sure that the batteries are changed every few months. The pilot still could be blow out with wind issues. If the unit was just started up, lets just say in IPI mode intermittent pilot ignition or was just put into CPI mode Continuous pilot ignition there can be cold air pushing down the exhaust pipe, not allowing the unit to exhaust properly. If that is the case, the unit cannot exhaust fast enough and burns up all the oxygen in the firebox causing the flames to be really blue and drop out. The unit being in IPI intermittent pilot ignition is very common with homeowners trying to save energy or a homeowners who forgot to turn the unit into CPI mode when the weather turns cold. By keeping the unit in CPI mode this will try and maintain an exhaust path so when the unit is turned on it can exhaust properly and supply the unit with outside air for combustion. There is nothing that is going to prevent wind from taking out a pilot. The unit will attempt to light the pilot 3 times. After the 3rd unsuccessful attempt in a row, the unit will go into lockout mode. Wind, deposits on flame rod (soot & silicon off gassing), gas pressures, improper voltages, flame not hitting the rectification rod will also put the unit into lockout mode. Please refer to page 11 or page 21 for clearing lockout mode. 55

Mendota DXV60 & DXV 45 Rear Burner Instructions Mendota has improved the rear burner in the DXV60 & DXV45 units. The part numbers for the burners have not changed; they are still the same part numbers. A bracket has been added to help prevent the rear logs from falling forward, along with holes to assist in lighting the rear burner. Please use the below instructions for the DXV 60 & 45 units.

Labored startup during extreme cold weather, resulting in the unit ghosting, a condition caused by the inability to expel the exhaust gases from the combustion chamber caused by cold air infiltrating and capping the exhaust liner, causing loss of rectification, and dropping out repeatedly until going into lock out. As well as negative house pressures, when the draft pressure inside the home is stronger than the draft pressure inside the unit creating the inability to expel exhaust gases or the tendency to exhaust thru the intake air channels. A scenario that can be caused in an extremely tight home and possibly the combination of powered exhaust fans, attic vents etc. In working thru many hours of these system failures with technicians in the field, Mendota Technical Services has discovered that in most every case these symptoms can be corrected with the use of a complete co-linier vent system, and strongly recommend : 1. Installing both air intake and exhaust liners completely to the termination cap, utilizing a direct vent termination cap with both air intake and exhaust connections, thus creating a Direct Vent system, drawing combustion air and expelling exhaust to the outside of the structure, guaranteeing air quality within the home. 2. Do not insulate the damper area of the existing fireplace. Do insulate the top of the existing flue cavity. Please use un-faced insulation and insulating the top of the existing flue cavity approximately 2 down, This should eliminate cold air infiltration into the flue cavity as well as room space where the existing fireplace is located. Leaving the existing fireplace damper area open will allow residual heated air to infiltrate and warm the existing flue cavity. This will allow the exhaust liner to stay warmer and maintain a stronger draft eliminating the possibility of cold air coming down the exhaust liner and creating negative pressure within the venting system. 3. In the Northern tier, extremely cold climate areas or in extremely tall fireplace applications, insulate the exhaust liner. The pilot light produces a very small amount of BTU output; however, it is what is responsible for maintaining draft between burn cycles. The colder the climate, the quicker the cold air will infiltrate the exhaust liner and the further down the length of the liner it will be able to travel between cycles. Also, the further away termination is from the unit, the more the ability to maintain heat in the exhaust liner decreases. 4. It is imperative that the unit be ran in CPI throughout the burn season. No amount of insulation or any type of venting configuration will make up for the lack of pilot heat maintaining draft between burn cycles. Not only will leaving the unit in standing pilot maintain draft, it will help eliminate the buildup of condensation within the unit and vent system, eliminating corrosion and prolonging the life of components. 57
