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. The water heater must be installed outdoors.
• 4. 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).
• 5. Keep water heater area clear and free from combustibles
and flammable liquids. Do not locate the heater over any
material which might burn.
• 6. 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 section 6.1 on
connecting the gas supply.
• 7. 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.
• 8. Do not use this appliance if any part has been
underwater. Immediately call the person responsible for
the installation of your appliance to inspect the appliance
and to replace any part of the control system and any gas
control which has been underwater.
• 9. Failure to install the heater correctly may lead to unsafe
operation.
