NSTALLATION

When purging the gas lines, the front glass must 

be 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 some additional local 

codes it is always best to consult your local authority and the 

CAN/CGA-B149 (.1 or .2) installation codes.

For U.S.A. Installations consult the current National Fuel Gas 

Code, ANSI Z223.1

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 pres-

sure test point, therefore it is not necessary to provide a 1/8” 

test point up stream of the control.

When using copper or flex connectors use only approved fit-

tings.  Always provide a union when using black iron pipe 

so that the gas line can be easily disconnected for burner or 

fan servicing.  See the gas specification for pressure details 

and ratings.

The fireplace valve must not be subjected to any test pressures 

exceeding 1/2 p.s.i..  Isolate or disconnect this and any other 

gas appliance control from the gas line when pressure testing.

Installation

1.  Thread the wiring through the holes on the end panels of 

the appliance.  Take care not to cut the 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 

as shown in Fig. 6.

Alternative Switch Location

The remote switch can be installed on the front/side of the 

access door.  Simply mount the switch to the bracket provided 

and screw the bracket to either side of the frame, lining up the 

screws with the pre-punched holes, Fig. 7.

Do not wire the remote ON/OFF wall switch for 

the gas fireplace to the 120 volt power supply.
