RULES FOR SAFE OPERATION
1.You should follow these instructions when you install your heater.
In the United States: The installation must con- form with local codes or, in the absence of lo- cal codes, the National Fuel Gas Code ANSI Z223.1/NFPA 54.
In Canada: The installation should conform with CGA B149.(1,2) INSTALLATION CODES and/or local installation codes.
2.Carefully plan where you install the heater. Correct combustion air supply and flue pipe installation are very important. If the gas appliance is not installed correctly, fatal
accidents can result from lack of air, carbon monoxide poisoning or fire.
3.The place where you install the heater must have enough ventilation. The National Fire Codes do not allow water heater installation in bathrooms, bedrooms or any occupied rooms normally kept closed. See the section on Pages
4.You must vent your heater. See section on Vent Pipe Connection, Page 10, paragraph 6 and Venting Guide on page 27.
5.The appliance and its individual shutoff valve must be disconnected from the gas supply pip- ing system during any pressure testing of that system at pressures in excess of 1/2 psig (3.5kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure test- ing of the gas supply piping system at test pres- sures equal to or less than 1/2 psig (3.5kPa). The appliance and its gas connection must be leak tested before placing the appliance in op- eration
6.Keep water heater area clear and free from combustibles and flammable liquids. Do not locate the heater over any material which might burn, such as carpet.
7.Correct gas pressure is critical for the opti- mum operation of this heater (see specifications on page 3). Gas piping must be sized to pro- vide the required pressure at the maximum output of the heater. Check with your local gas supplier, and see gas line size requirements on page 27.
8.As a precaution, shut off your heater if you plan to be away for several days.
9.Should overheating occur and the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
10.See instructions on setting the water tem- perature, page 12.
11.Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.
