WATER CLOSET SUPPORTS TECHNICAL DATA

1 WATER CLOSET SUPPORTS TECHNICAL DATA Smith engineers have developed an unusually omplete line of fixture supports for mounting all types of "off the floor" fixtures. Supports have been designed for water losets, urinals, lavatories, sinks, drinking fountains and many speial purpose hospital, institutional and industrial plumbing fixtures. DEFINITION Fixtures whih are wall mounted and have no external ontat with the finished floor are lassified as "off the floor plumbing fixtures." Fixtures so mounted are supported on onealed ast iron or steel supports (arriers). These supports are ompletely onealed in the wall, and support the load of the fixture by means of a suitable fae plate and base support whih is firmly anhored to the floor. Thus the load of the fixture is effetively taken off the wall and transmitted to the floor. WATER CLOSET SUPPORT SYSTEMS By inorporating a waste fitting whih funtions in onjuntion with the support setion, an entire system of "Combined Fixture Supports and Waste Fittings" has been developed. Thus, when mounting "off the floor" water losets, a omplete unit is available whih supports the fixture and inludes a fitting whih will tie into the drainage piping system. Fittings are available in vertial and horizontal patterns. Used in ombinations, these fittings an satisfy waste and vent requirements of most systems. Smith engineers have worked losely with plumbing designers, ontrators and ode offiials to develop a system whih meets their rigid demands and requirements. Partiular attention was given in design so that--- the engineer an selet supports with fittings to meet all problems reated by arhitetural, strutural, ode or estheti requirements. the plumbing ontrator an easily and eonomially install a rigid and ode approved support with fitting, whih will funtion for the lifetime of the building. ADVANTAGES OF "OFF THE FLOOR" WATER CLOSETS OVER FLOOR MOUNTED Design--The omplete line of fittings available offers great latitude to arhitets and engineers when laying out the spaing, piping diagrams and wall spae requirements for plumbing fixtures. The Smith system offers the engineer an option of designing a plumbing drainage system whih is ompat, yet extremely funtional. The arhitet is assured that the system uses a minimum of floor spae, with all the neessary omponents inluded. Installation--Off the floor water loset systems an be installed more eonomially than onventional floor mounted systems. This omparison is partiularly obvious in multi-story buildings whih have batteries of water losets on eah floor. The ontrator is assured a simple, fast and effiient installation. Off the floor systems redue osts for the following reasons: 1. Less sleeving. In most ases only one sleeve is required to take are of the vertial inlet fitting at the start of the horizontal run. 2. Sine all the roughing is done on the floor and not in the eiling below, no saffolding, ladders or similar supports are required (Fig. 1). 3. The installer works on the floor (Fig. 2) and not in the eiling below; thus, time is saved sine working onditions are more favorable. 4. Beause all the rough-in piping is on the floor above, "dropped eilings" are not required; thus, eiling spae is saved. This enables building eiling height to be lower, effetively saving overall onstrution osts. the ode offiial is assured that fittings used with supports are designed to meet ode requirements relative to the proper sizing for drainage piping and venting. Fig. 2 INSTALLING PIPING FOR "OFF THE FLOOR" FIXTURES Fig. 1 INSTALLING PIPING FOR FLOOR MOUNTED FIXTURES Sanitation--After the building is turned over to the owners, ost for leaning in the area under the "off the floor" water losets is onsiderably less than in similar areas whih have floor mounted fixtures. A mop is easily passed under off the floor fixtures thoroughly leaning the floor beneath as ompared to the very diffiult task of leaning around and in bak of floor mounted water losets. Cleaning osts are redued, and the toilet room is maintained in a more sanitary ondition.

2 TYPES OF WATER CLOSETS SIPHON JET The siphon jet bowl is the most ommon beause its ation is relatively silent and eonomial in water usage. It operates by a jet of water direted through the trapway whih quikly fills and starts the siphoni ation immediately upon flushing. Its quiet ation and large water surfae, among other features, make it the most desirable bowl type. It is readily distinguished by the four bolt holes whih reeive the fixture support studs. BLOWOUT The blowout bowl is partiularly adapted for publi use as in airports, stadiums or plant washrooms. Its ation is a driving one of high veloity. It is eonomial in water use and has a large water area and an unrestrited trapway. It is also more noisy than the siphon jet bowl beause of its diret jet ation. The blowout bowl is seured to the supports by three studs. TYPICAL BATTERY INSTALLATIONS Fig. 0210RY Fig. 0240RY Fig. 0210LY Base support must be seurely anhored to a rigid floor and/or other rigid substruture with 1/2" bolts furnished by others. Battery of horizontal fittings with adjustable loset supports used in onjuntion with a vertial fitting. SUFFIX -M17 WATER CLOSET SETTING GAUGE Battery of horizontal fittings with adjustable loset supports onneted to a stak fitting. The arhitets onstrution design and physial layout of the toilet room ditates the type of fittings that an be seleted by the engineer for battery installations. The engineers drainage and vent system design must be in aordane with the loal plumbing ode in fore. Smith's lightweight ast aluminum water loset setting gauge is available for siphon jet bowls. The gauge has the same dimensions as the rear of the "off the floor" siphon jet bowl and is designed to eliminate ostly trial and error test mounting and redue the number of bowl "lifts" per day. The gauge loates the orret position of bearing washers and nuts, loates the orret protrusion of outlet oupling and support studs and heks the plumb of the wall. When the bowl is lifted, it's ready to be installed. Features of the Closet Setting Gauge inlude: 1. Leveling pads to hek horizontal alignment. 2. Four openings to hek vertial and horizontal stud alignment. 3. Four extensions to determine stud length. 4. Vertial plumb line. 5. Four reesses in bak of gauge for positioning of bearing washers. 6. Opening with oupling setting loations for outlet onnetion. Mark Slip gauge over studs and hold tight against wall. Chek for plumb and level. Adjust bearing washers and nuts to fit tight against bak of gauge. Make neessary adjustments for alignment of studs. Hold gauge tight against wall and adjust outlet oupling flush with pad orresponding to loset horn depth. Hold gauge tight against bearing nuts and washers, and mark ut-off point of studs flush with gauge extensions. Remove gauge and ut off studs. Install bowl.

3 SELECTION OF VERTICAL FITTING WITH SIDE INLETS DETERING LEFT OR RIGHT HAND HORIZONTAL FITTINGS Stak Fig. 0210LY Fig. 0250RY STACK Fig. 0210RY LEFT HAND RIGHT HAND Seleting the proper vertial stak fitting is of prime importane sine that fitting with side inlets is the start of the horizontal battery of fittings and supports. To determine left or right hand fitting, fae the stak from the fixture side of the wall. If the inlet is to the left of the stak, it is a left hand fitting. If the inlet is on the right of the stak, it is a right hand fitting. The vent is always loated on the same side as the inlet on a single inlet stak fitting. LEFT HAND FACE STACK FROM FIXTURE SIDE RIGHT HAND Left or right hand fitting is always determined by faing the stak from the fixture side of the room. Closet fittings to the left of the stak are left hand fittings. Closet fittings to the right of the stak are right hand fittings.

The fae plate is designed for one-pour onstrution, onsisting of a single slab with fill and 1/4" finished material. Cut-off grooves provided on 0200 Series fae plates. This allows removal of tabs to aommodate 5" or 4 1/4" minimum roughs. ROUGHING OF VERTICAL ADJUSTABLE FITTINGS WITH SIDE INLETS Sub Floor 3" minimum shown is attained using Regularly Furnished ABS Nipple and Adjus-to-Wall Coupling. Absolute Minimum of 1 1/2" is available using short butt end nipple, less Adjus-to-Wall Coupling ROUGH FLOOR SLAB SIPHON JET BLOWOUT Siphon Jet--The loation of the side inlet is determined by the enter of the loset outlet to the finished floor plus the thikness of the finished floor materials. This will determine where the inlet will be in relation to the rough floor. For shallow roughing (0200 Series) or one-pour slab onstrution, the side inlet should always set on the slab floor. Shown is the minimum pipe spae required for a single and double horizontal support. Blowout--The loation of the side inlet should be set in the lowest position from enter line of the loset outlet to enter line of side inlet.

COMPACT FIXTURE SUPPORTS Smith ompat fixture supports with waste fittings are designed speifially for installation where non-adjustable vertial fittings are suitable for onstrution requirements and minimum pipe spae is of prime onsideration. These supports are available in both offset and enter line waste type. The offset waste type features an absolute minimum enter to bak dimension and is arranged with vertial vent onnetion making it suitable for multi-story installation. The enter line waste type does not have the vent onnetion and is limited to single story installations. The extension of the vertial waste line is the stak vent. Both types are available for siphon jet or blowout loset appliations. 6 Closet Gasket ABS Adjus-to-Wall Coupling 2 1/2" Long Yoke Nipple-End Threaded For Distane Of 4" 5/16 X 6" Studs With Nuts And Washers *4 X 12" Long Nipple-Tapered Thread On One End And 4" Straight Thread On Coupling End TYPE -M74 CLOSET OUTLET CONNECTOR FOR USE WITH STAINLESS STEEL FIXTURES Stak Fitting Outlet Connetion Fae wall looking into loset outlet onnetion.
