C34-VF Gas Fireplace
Part No. XG0316
Installing The Gas Line
The gas line must be installed before finishing the C34-VF Fireplace.
Natural gas requires a minimum inlet gas supply pressure of 5.5"
W.C. & a manifold pressure of 3.5" W.C. Propane gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure
of 10" W.C. Provision must also be made for a 1/8" N.P.T. plugged
tapping and be accessible for test gauge connection immediately
upstream of the gas supply controls to the appliance. The fireplace
gas connection and the main operating gas valve is located behind
the removable brass trim at the bottom of the unit and need only be
attached to the gas line with an approved fitting, as required by the
applicable installation codes.
Installation
Note: After gas line is connected, each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten
any areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks.
Installing The Remote Switch
The C34-VF's gas valve, located behind the lower trim, may be
connected to a wall switch. The valve generates its own power on a
millivolt circuit. Use only low voltage wire, and DO NOt connect
any external power to it.
Refer to Figure 11 for wiring requirements.
Note: The switch location must not exceed 30' from the fireplace.

The appliance and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).
WARNING:
Do not allow fans to blow directly into the fireplace. Avoid
any drafts that alter burner flame patterns.
Keep appliance area clear and free from combustion mate-
rials, gasoline and other flammable vapors and liquids.
Unusually tight construction is defined as construction where:
 Walls and ceilings exposed to the outside atmosphere have a
continuous water vapour retarder with a rating of 1 perm ( 6x 10 -11
kg per pa-sec-m 2 ) or less with openings gasketed or sealed, and
 Weather Stripping has been added on openable windows and
doors, and
 Caulking or sealants are applied to areas such as joints around
window doors and frames, between sole plates and floors, be-
tween wall-ceiling joints, between wall panels, at penetrations for
plumbing, electrical and gas lines, and at other openings.
