GAS SUPPLY AND PIPING
This unit requires a gas control shut-off valve to be
supplied by the installer. It must be placed on the
unit before it is connected to the gas line.
Check that the gas inlet pressure and the type of
gas matches the rating plate located on your water
heater. Insufficient gas pressure will cause your
AQ240FX Water Heater to be inefficient and not
work properly. Size the gas piping correctly.
For up to 25ft. ¾" Black Iron pipe is the
minimum pipe size required for Natural Gas.
For up to 25ft. ½" Black Iron is the minimum
pipe size required for LP.
For up to 10ft. 5/8" Copper is the minimum pipe
size required for LP.
Flex lines are not recommended, oversize if one
needs to be used.
See Gas Sizing tables on page 11.
Minimum and maximum inlet gas pressures are as
follows:
Natural Gas
Propane Gas
of
Maximum gas pressures must not exceed this
value.
After the connections are complete check for gas
leaks by applying soapy water to all gas fittings and
connections. Soap bubbles are a sign of gas leaks.
This appliance must be isolated from the gas supply
piping
system
disconnecting the main gas during any pressure
testing of the gas supply piping system at test
pressures equal to or more than ½ Psi. The
appliance and its gas connections must be leak
tested before placing the unit in operation.
Always use approved connectors to connect the
unit to the gas line. Always purge the gas line of
any debris before connection to the heater.
