Step 7. CONNECTING GAS LINE
Make gas line connections. All codes require a
shut-off valve mounted in the supply line. Figure
53 illustrates two methods for connecting the
gas supply. The flex-line method is acceptable
in the U.S., however, Canadian requirements
vary depending on locality. Installation must
be in compliance with local codes. A sediment
trap is recommended in the gas piping within
the home to prevent moisture and debris in the
line from damaging the valve.
These appliances are equipped with a gas flex
line for use (where permitted) in connecting the
unit to the gas line. A gas flex line is provided
to aid in attaching the Direct-Vent appliance to
the gas supply. The gas flex line can only be
used where local codes permit. The flex line is
rated for both natural and propane gas. A manual
shut off valve is also provided with the flex line.
The gas control valve is located in the lower
control compartment.
To access the valve open the lower control
compartment door (see Figure 54) by pushing
in the right top corner of the door. (The door
is hinged at the bottom.) Remove the bottom
compartment door by sliding the hinge pin,
located at the door's left side, to the right until
it disengages from the left corner post hole.
Pull the door diagonally to the left, away from
the fireplace.
The lower control compartment door on the
side opposite the valve lifts on and off.
Figure 53 - GAS CONNECTION
Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane
resistant compounds are used in propane
applications).
All codes require a shut-off valve mounted in
the supply line. The orientation of the shut-off
valve should face the front. Figure 53 illustrates
two methods for connecting the gas supply.
A sediment Trap is recommended to prevent
moisture and debris in the gas line for damag-
ing the valve.
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, us-
ing 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 recom-
mended, 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 the control compart-
ment or in the Installation 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
gas control knob (off/pilot/on) to the "OFF"
position. 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.

Step 8. VERIFYING APPLIANCE OPERA-
TION
Turn on burner and 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 in the Installation and Operation
Instructions manual.
NOTE: Lighting Instructions are also found on
the literature tag tied to the gas piping next
to the gas valve. To access the tag, open the
lower control compartment door (Figure 54) by
pushing in simultaneously the left and right top
corners of the door. (The door is hinged at the
bottom). Remove the bottom compartment door
by sliding the hinge pin, located at the door's
left side, to the right until it disengages from
the left corner post hole. Remove the modesty
panel. To remove the modesty panel, slide the
panel forward until it contacts the cabinet bot-
tom panel, then lift straight up and tilt forward.
Remove the modesty panel carefully, so that
none of the wires become loose or disconnected.
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 instruc-
tion manual.
Subsequent lighting of the appliance will not
require such purging. Inspect the pilot flame
(remove logs, if necessary, handling carefully).
