C38-VF Gas Fireplace
WARNING:
If the area in which the heater may be operated is smaller
than that defined as an unconfined space, or if the build-
ing is one of unusually tight construction, provide ad-
equate combustion air by one of the methods described in
the National Fuel Gas Code, ANSI Z223.1, Section 5.3 or
applicable local codes.
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
kg per pa-sec-m
) or less with openings gasketed or sealed, and
2
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, between
wall-ceiling joints, between wall panels, at penetrations for plumbing,
electrical and gas lines, and at other openings.
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
materials, gasoline and other flammable vapors and
liquids.

Installation
Installing The Gas Line
The gas line must be installed before finishing the C38-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.

Figure 6. Gas line access.
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).
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 C38-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 13 for wiring requirements.
Note: The switch location must not exceed 30' from the fireplace.
