9 1. Turn “OFF” the gas supply to the water heater . If the main gas line Shut-off valve serving all gas appliances is used, also shut “OFF” the gas at each appliance. Leave all gas appliances shut “OFF” until the water heater installation is completed, see Figures 3 and 4. 2. Turn “OFF” the water supply to the water heater at the w[...]

10 FACTS TO CONSIDER ABOUT THE LOCA TION Carefully choose an indoor location for the new water heater , because the placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance. This water heater is not for use in manufactured (mobile) homes or outdoor installation. Whe[...]

11 and 12" (30.5 cm) from the top. (S tandard clearance.) If clearances stated on the heater differ from standard clearances, install water heater according to clearances stated on the heater . Adequate clearance for servicing this appliance should be considered before installation, such as changing the anodes, etc. A minimum clearance of 5&qu[...]

12 Chemical vapor corrosion of the flue, blower assembly and vent system may occur if air for combustion contains certain chemical vapors. S pray can propellant s, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes, bleach and process chemicals are typical compounds which ar[...]

13 The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion.[...]

14 Figure 16 shows the typical attachment of the water piping to the water heater . The water heater is equipped with 3/4 inch NPT water connections. NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder the cold water supply line directly to the cold water inlet. It[...]

15 GAS PIPING Make sure the gas supplied is the same type listed on the model rating plate. The inlet gas pressure must not exceed 14 inch water column (3.5 kPa) for natural and propane gas (L.P .). The minimum inlet gas pressure shown on the rating plate is that which will permit firing at rated input. All gas piping must comply with local codes a[...]

16 SEDIMENT TRAPS Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. T o trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated i[...]

17 VENT CONNECTIONS TO BLOWER ASSEMBL Y Figure 15 shows the optimal placement of the 2" to 3" or 3" to 4" reducer; however , the vent can be reduced at any point in the vent system as long as the maximum vent length is not exceeded. FIGURE 21. VENTING AND INST ALLA TION Plan the layout of the vent system from the vent terminatio[...]

18 The unit may be vented horizontally through a wall or vertically through the roof. Pipe runs must be adequately supported along both vertical and horizontal runs as follows: • For Schedule 40, 2" PVC, ABS, Coex Cellular Core vent pipe: Every 3 feet (0.9 m). • For Schedule 40, 3" PVC, ABS, Coex Cellular Core vent pipe: Every 3.5 fee[...]

19 VENTING The vent system must terminate so that proper clearances are maintained as cited in local codes or the current edition of the Natural Gas and Propane Installation Code CAN/CSA B149.1 as follows: 1 . The exit terminals of a mechanical vent system shall be not less than 7 feet (2.13 m) above grade when located adjacent to public walkways, [...]

20 FIGURE 23. This unit can vent through 2", 3" or 4" nonmetallic pipe and fittings. The vent pipe installation can be started from either the blower discharge or the termination wall. Keep in mind the total vent system (pipe and elbows) when installing the vent system, see VENTING AND INST ALLA TION AND MAXIMUM VENT LENGTHS, pages 1[...]

21 VENT PIPE PREP ARA TION 1. INITIAL PREP ARA TION A. Make sure the solvent cement you are planning to use is designed for the specific application you are attempting. B . Know the physical and chemical characteristics and limitations of the PVC and CPVC piping materials that you are about to use. C . Know the reputation of your manufacturer and t[...]

22 B . Deburring Use a knife, plastic pipe deburring tool, or file to remove burrs from the end of small diameter pipe. Be sure to remove all burrs from around the inside as well as the outside of the pipe. A slight chamfer (bevel) of about 10°- 15° should be added to the end to permit easier insertion of the pipe into the end of the fitting. Fai[...]

25 FOR YOUR INFORMA TION ST ART UP CONDITIONS CONDENSA TE Whenever the water heater is filled with cold water , some condensate will form while the burner is on. A water heater may appear to be leaking when in fact the water is condensate. This usually happens when: a . A new water heater is filled with cold water for the first time. b . Burning ga[...]

26 SER VICE AND ADJUSTMENT VENTING SYSTEM INSPECTION At least once a year a visual inspection should be made of the venting system. Y ou should look for: 1. Obstructions which could cause improper venting. The combustion and ventilation air flow must not be obstructed. 2 . Damage or deterioration which could cause improper venting or leakage of com[...]

27 ANODE ROD INSPECTION The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water’s taste or color . The rod must be maintained to[...]
