Step 6. CONNECTING GAS LINE
All codes require a shut-off valve mounted in
the supply line. The orientation of the shut-off
valve should face the front. Figure 30 illustrates
two methods for connecting the gas supply.
A Sediment Trap is recommended to prevent
moisture and debris in gas line from damaging
the valve.
The flex-line method is acceptable in the USA
where local codes permit. Installation must be in
compliance with local codes. These appliances
are equipped with a gas flex-line for use in
connecting the unit to the gas line.See Figure
30 for flex-line description.
A manual shutoff valve is also provided with
the flex-line. The gas control valve is located
on the right side of the unit.
When using solid gas line connector, access
the valve by removing the front door assembly
on the valve access side and the access plate
(see Figure 29).
The electronic control valve has a 3/8" (10 mm)
NPT thread gas supply inlet.
Secure all joints tightly using appropriate
tools and sealing compounds.
Bring the shutoff valve on the end of the flex-line
over to the hard pipe and tighten with wrenches
from above through the firebox opening.

TEST ALL CONNECTIONS FOR GAS LEAKS
(FACTORY AND FIELD)
WARNING
Never use an open flame to
check for leaks.
Turn on gas supply and test for gas leaks using
a gas leak test solution (also referred to as
bubble leak solution).
NOTE: Using a soapy water solution is
an effective leak test solution but it is not
recommended, because the soap residue
that is left on the pipes/fittings can result in
corrosion over time.
A. Light the appliance (refer to the lighting
instructions label in control compartment
or in the Care and Operation instructions
manual).

B. Brush all joints and connections with the
gas leak test solution to check for leaks.If
bubbles are formed, or gas odor is detected,
turn the unit off. Either tighten or refasten the
leaking connection, then retest as described
above.
C. When the gas lines are tested and leak free
be sure to rinse off the leak testing solution.
D. Re-install the access plate, making certain
the gasket has not been damaged.
Step 7. INSTALL FIREBOX LINER KIT
Install the firebox liner kit per the included
instructions.
Step 8. VERIFYING APPLIANCE
OPERATION
Turn on burner then observe the individual
tongues of flame on the burner. Make sure all
ports are open and producing flame evenly
across the burner. If any ports are blocked, or
partially blocked, clean out the ports.
With gas line installed run initial system
checkout before closing up the front of the unit.
Follow the pilot lighting instructions provided.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
NOTE: Lighting Instructions are also found on
the literature tag tied to the bracket above the
gas valve. To access the tag, reach into the
right side opening.
When first lighting the appliance, it will take a few
minutes for the line to purge itself of air. Once
purging is complete, the pilot and burner will
light and operate as indicated in the instruction
manual. Subsequent lighting of the appliance will
not require such purging. Inspect the pilot flame
(remove logs, if necessary, handling carefully).

To light the burner, turn the ON/REMOTE/OFF
wall switch or remote control to the ON posi-
tion. Ensure the igniter lights the pilot. The pilot
flame should engulf the flame sensor as shown
in Figure 31.
NOTE: The control must detect the pressure
switch in the open state, at startup, and then
close after the blower starts.

NOTE: The gas supply line
must be installed in accor-

be performed by a licensed
plumber or gas fitter.
