LDVT Series Direct Vent Gas Fireplace
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to 4,500
feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the cur-
rent ANSI Z223.1/NFPA 54 and/or local codes having
jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).
Gas Line Installation
When purging gas line, the front window frame
removed.
The gas pipeline can be brought in through the rear of the
fireplace 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 approved flex con-
nector. Since some municipalities have additional local
codes, it is always best to con- sult your local authority
and the National Fuel Gas Code, ANSI Z223.1/NFPA 54 in
the USA or the CSA-B149.1 installation codes.
1/2" Gas Supply
Fig. 5 Typical gas supply installation.
Always check for gas leaks with a mild soap
and water solution. Do not use an open flame
for leak testing.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide
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 that the gas line can be easily disconnected for burner
or fan servicing . See gas specifications for pressure details
and ratings.

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 from the gas line when
pressure testing.
Installation:
1. Thread the wiring through holes on the end panels of
appliance. Take care not to cut wire or insulation on
metal edges. Route the wire to a conveniently located
receptacle box.
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box.
3. Connect the other ends of the wire to the gas control
valve. (Fig. 6)
