rigid tubing or an approved flex connector. Since some
municipalities have additional local codes it is always best
to consult your local authorities and the current edition of
the National Fuel Gas Code ANSI.Z223.1, NFPA54. In
Canada CSA-B149 (1 or 2) Installation Code.
A listed manual shutoff valve must be installed upstream
of the appliance. Union tee and plugged

IMPORTANT:
Install main gas valve (equipment shutoff
valve) in an accessible location. The main gas valve is for
turning on or shutting off the gas to the fireplace.
Check your building codes for any special requirements for
locating equipment shutoff valve to fireplaces.

Use pipe joint sealant that is resistant to
liquid petroleum (LP) gas.

Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess seal-
ant in pipe could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg in
supply line as shown in
Figure 32
. Locate sediment trap/
drip leg where it is within reach for cleaning. Install in piping
system between fuel supply and burner system. Locate
sediment trap/drip leg where trapped matter is not likely
to freeze. A sediment trap collects moisture and contami
-
nants and keeps them from going into the burner system
gas controls. If sediment trap/drip leg is not installed or is
installed wrong, burner system may not run properly.

CHECK GAS PRESSURE
1. Check gas type. The gas supply must be the same as
stated on the appliance’s rating decal. If the gas supply
is different from the fireplace,
STOP!
Do not install the
appliance. Contact your dealer immediately.
2. To ease installation, a 24" (610 mm) flex line with manual
shut-off valve has been provided with this appliance.
Install and attach
1
⁄
2
" gas line onto shut-off valve.
3. After completing gas line connection, purge air from
gas line and test all gas joints from the gas meter to
the fireplace for leaks. Use a solution of 5
0
⁄
50
water and
soap solution or a gas sniffer.
4. To check gas pressures at valve, turn captured screw
counter clockwise 2 or 3 turns and then place tubing
to pressure gauge over test point. Turn unit to high.
Figure 33.
After taking pressure reading, be sure and
turn captured screw clockwise firmly to reseal. Do not
over torque. Check test points for gas leaks.

Do not use open flame to check for gas
leaks.
