XDV Direct Vent Gas Fireplace
Gas Line Installation
When purging the gas lines, the front win-
dow frame assembly must be removed.
The gas pipeline can be brought in through the rear
of the appliance as well as the bottom. Knockouts are
provided on the bottom behind the valve to allow for the
gas pipe installation and testing of any gas connection.
It is most convenient to bring the gas line in from the
rear right side of the valve as this allows fan installation
or removal without disconnecting the gas line.
The gas line connection can be made with properly
tinned 3/8” copper tubing, 3/8” rigid pipe or an ap-
proved flex connector. Since some municipalities have
additional local codes, it is always best to consult your
local authority and the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 in the USA or the CSA-B149.1 installa-
tion code.

Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25 mm). Never
apply soap and water solution with a spray
bottle. Do not use an open flame for leak
testing.
The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas
appliance control form the gas line when
pressure testing.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8” test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so the gas line can be easily disconnected for
burner or fan servicing. See gas specification for pres-
sure details and ratings.
The fireplace valve must not be subjected to any test
pressures exceeding 1/2 psi. Isolate or disconnect this
and any other gas appliance control from the gas line
when pressure testing.
Remote ON/OFF Switch
Do not wire the remote ON/OFF wall switch for this gas
appliance into a 120v power supply.
1. Thread wire through the electrical knockout located
on either side of the unit. Take care not to cut the
wire or insulation on metal edges. Ensure the wire is
secured and protected form possible damage. Run
one end of the gas control valve and the other end to
the conveniently located wall switch.
2. Attach the wire to the ON/OFF switch and install
switch into receptacle box. Attach cover plate to
switch.
3. Connect wiring to gas valve. (Fig. 7)
