WDV Series Gas Fireplace
FINAL INSTALLATION
NOTE:
The gas line connection may be made using 1/2"
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 1/8" NPT pressure
tapping point should be installed upstream of the appliance.
Figure 32
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.
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.

Only persons licensed to work with gas
piping may make the necessary gas
connections to this appliance.
CAUTION
A manual shutoff valve must be installed
upstream of the appliance. Union tee
and plugged 1/8" NPT pressure tapping
point should be installed upstream of the
appliance.

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

Do not use open flame to check for gas
leaks.
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 contaminants
and keeps them from going into the burner system gas con-
trols. If sediment trap/drip leg is not installed or is installed
wrong, burner system may not run properly.
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 50/50 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.
Fig-
ure 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.
