B 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 CGA
B149.(1,2) INSTALLATION CODES and /or local
installation codes.

installed correctly, fatal accidents can occur, such as
carbon monoxide poisoning or fire.
B 3. The water heater must be installed outdoors using
the outdoor kit and/or recess box accessory.
B 4. You must vent your heater so that the exhaust
gases discharge to the outdoors.

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

kPa).

combustibles and flammable liquids. Do not locate
the heater over any material which might burn.

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 7.1 .
B 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.

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
