Gas Supply Installation
•• It’’s preferable to rough-in the gas line at this point
before proceeding with the  rebox installation.
•• The appliance is supplied for supply gas connection
at the control valve. Supply line connection to
the control valve of the appliance is 3/8 inch NPT
(female).
Take care not to apply torque to the valve. An
isolating valve may be
 tted within the appliance
case. Be aware that the supply pipe should follow
routing to clear the remote receiver or optional fan.
•• Use only new black iron or steel pipes or copper
tubing if acceptable——check local codes. Note that
in USA, copper tubing must be internally tinned for
protection against sulfur compounds.
•• Unions in gas lines should be of ground joint type.
•• The gas supply line must be sized and installed
to provide a supply of gas suf  cient to meet the
maximum demand of the appliance without undue
loss of pressure.
•• Sealant used must be resistant to the action of all
gas constituents including LP gas. Sealant should
be applied lightly to male threads to ensure excess
sealant does not enter gas lines.
•• The supply line should include a manual shut-
off valve and union to allow the appliance to be
disconnected for servicing.
•• Pressure test the supply line for leaks.
• The appliance and its individual shut-off valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at test pressures in excess of 1/2
psig (3.5kPa).
• The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5kPa).
•• Failure to either disconnect or isolate the appliance
during pressure testing may result in regulator or
valve damage. Consult your dealer in this case.
•• The minimum supply pressure is given in
Speci fi cations section of this manual.
•• All piping and connections must be tested for leaks
after installation or servicing. All leaks must be
corrected immediately.

•• When testing for leaks:
•• Make sure that the appliance is turned off.
•• Open the manual shut-off valve.
•• Test for leaks by applying a liquid detergent
or soap solution to all joints. Bubbles forming
indicate a gas leak.
Never use an open fl ame
to check for leaks .
•• Correct any leak detected immediately.
•• The pressure test tapping locations are shown in
 gure below. A built-in non-adjustable regulator
controls the burner manifold pressure. The
correct pressure range is shown in the table in the
Speci fi cations section of this manual. The pressure
check should be made with the burner alight and at
its highest setting. See
Lighting Instructions section
for full operating details.
