3.4 General rules to follow for safe operation

• 1. You must follow these instructions when you install your heater. In

the United States: The installation must conform with local codes or,

in the absence of local codes, the National Fuel Gas Code ANSI

Z223.1/NFPA 54.

In Canada: The Installation must conform with CSA B149.(1,2)

INSTALLATION CODES and /or local installation codes.

• 2. Carefully plan where you install the heater. Correct combustion air

supply and vent pipe installation are very important. If not installed

correctly, fatal accidents can occur, such as carbon monoxide

poisoning or fire.

• 3. When the unit is installed indoors and ROOM SEALED (twin pipe)

it is permitted to be located in bathrooms, bedrooms and occupied

rooms that are normally kept closed. See chapter 4.3 (page 11). If

the unit will be installed indoors and use indoor combustion air, the

place where you install the heater must have enough ventilation. The

National Fuel Gas Codes do not allow UNSEALED gas fired water

heater installations in bathrooms, bedrooms or any occupied

rooms normally kept closed. See chapter 4.4 (page 23).

• 4. You must correctly vent your heater. See chapter 4.3 (page 11) on

VENTING.

• 5. The appliance and its gas connection must be leak tested before

placing the appliance in operation.

The appliance must be isolated from the gas supply piping system by

closing its individual manual gas shutoff valve (not supplied with

heater) during any pressure testing at pressures in excess of ½ Psig

(3.5 kPa).

• 6. Keep water heater area clear and free from combustibles and

flammable liquids. Do not locate the heater over any material which

might burn.

• 7. Correct gas pressure is critical for the proper operation of this

heater. Gas piping must be sized to provide the required pressure at

the maximum output of the heater, while all the other gas appliances

are in operation. Check with your local gas supplier, and see the

section on connecting the gas supply. See chapter 4.8 (page 25).

• 8. Should overheating occur or the gas supply fail to shut off, turn off

the gas supply at the manual gas shut off valve, on the gas line. Note:

manual gas shutoff valve is not supplied with the heater but must be

field installed.

• 9. Do not use this appliance if any part has been underwater.

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 underwater.

• 10. Failure to install heater correctly may lead to unsafe operation

and void the warranty.
