INSTALLATION
GAS CONNECTION
Only persons licensed to work with gas piping
may make the necessary gas connections to
this appliance.
The gas connection is a 3/8" NPT accessible on
the left side of the unit. The gas line connection
may be made of rigid pipe, copper pipe or an
approved fl ex connector. (If you are using rigid
pipe, ensure that the valve can be removed
for servicing.) Since some municipalities have
additional local codes it is always best to consult
with your local authorities and the CAN/CGA
B149 installation code.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so that
gas lines can be easily disconnected for burner
or fan servicing. Flare nuts for copper lines and
fl ex connectors are usually considered to meet
this requirement.
Important: Always check for gas leaks
with a soap and water solution or gas
leak detector. Do not use open fl ame
for leak testing.
For minimum and maximum supply pressure
see the System Data table.

Note: During any pressure testing of the gas
supply piping system that exceeds test pressures
of 1/2 psig, this appliance and its individual
shut-off valve must be disconnected from the
piping system. If test pressures equal to or less
than 1/2 psig are used then this appliance must
be isolated from the piping system by closing
its individual manual shut-off valve during the
testing.
CAUTION: If the glass is removed for
servicing, it must be replaced prior to
operating the appliance. The glass must
be fixed in the closed position when
operating.
