Never obstruct the flow of ventilation air. If you have any doubts or questions at all, call your gas supplier. Failure to provide the proper amount of combustion air can result in a fi re or explosion and cause death, serious bodily injury, or property damage. • Install water heater in accordance with the instruction manual and CAN/CSA B149.1-current edition (Natural Gas and Propane Installation Code) and all local/ provincial codes. • To avoid injury, combustion and ventilation air must be taken from outdoors. • Do not place chemical vapor emitting products near water heater. If this water heater will be used in beauty shops, barber shops, cleaning establishments, or self-service laundries with dry cleaning equipment, it is imperative that the water heater or water heaters be installed so that combustion and ventilation air be taken from outside these areas. Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable in many cases, will also change to corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure. INSULATION BLANKETS 8 Insulation blankets are available to the general public for external use on gas water heaters but are not necessary with these products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your water heater meets or exceeds the minimum efficiency requirements with respect to insulation and standby loss requirements, making an insulation blanket unnecessary. Should you choose to apply an insulation blanket to this heater, you should follow these instructions (For identification of components mentioned below, see Figure 1). Failure to follow these instructions can restrict the air flow required for proper combustion, potentially resulting in fire, asphyxiation, serious personal injury or death. • Do not apply insulation to the top of the water heater, as this will interfere with safe operation of the draft hood. • Do not cover the outer door, thermostat or temperature & pressure relief valve. • Do not allow insulation to come within 2” (50.8 mm) of the fl oor to prevent blockage of combustion air flow to the burner. • Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference. • Do obtain new warning and instruction labels from the manufacturer for placement on the blanket directly over the existing labels. • Do inspect the insulation blanket frequently to make certain it does not sag, thereby obstructing combustion air fl ow. INSTALLING THE NEW WATER HEATER WATER HEATER INSTALLATION 1. To locate the position of the 3 1/2” (8.89 cm) or 4 1/2” (11.43 cm) hole to be cut in the floor, see Figures 5 and 6. FIGURE 5. FIGURE 6. 2. If you have found that the water heater is being installed in an area which, if the water heater was to leak, would cause damage and have elected to install a metal drain pan refer to Figures 7, 8 and 9 on page 10. If you are not installing a drain pan go directly to the next step. NOTE: Clearances from combustible or non combustible surface to jacket will change template dimensions. 9 4. Set the water heater in place against the lip of the duct assembly as shown in Figure 11. FIGURE 7. FIGURE 11. 5. Secure the water heater to the duct assembly using the screw provided. NOTE: See pages 12 and 13 for installing an air intake through an outside wall when the manufactured home is located over a basement or crawl space. SECURING WATER HEATER TO FLOOR AND WALL The water heater must be secured to the floor and to the wall of the enclosure with the three mounting brackets and screws packaged in the carton with the water heater. The two small brackets are used to attach the water heater to the floor and the one large bracket is used to secure the top of the water heater to the wall. Because of installation variances these brackets can be located at any points around the circumference of the jacket. When the bracket locations are determined using the 1/8 inch drill bit for a pattern, drill only through the outer jacket of the water heater. Then using the screws provided, secure the bracket to the water heater, fl oor and wall, see Figure 12. FIGURE 8. FIGURE 9. 3. Insert the duct assembly as shown in Figure 10 with lip facing forward, and using only nails, secure the duct assembly to the fl oor. FIGURE 12.

Cut 5 1/2” (13.97 cm) diameter holes through the roof and ceiling directly in line with the flue connection on top of the water heater. For a sloped roof, the roof hole may have to be enlarged to allow the roof jack to be installed vertically. 2...
