LDVT Series Direct Vent GaS Fireplace

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)
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 connector. Since some municipalities have ad-
ditional 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 installa-
tion codes.
Do not wire the remote ON/OFF wall switch
for the gas fireplace to the 120 volt power
supply.
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 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 that the gas line can be easily disconnected for
burner or fan servicing . See gas specifications for pres-
sure details and ratings.
