24VF 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 building
is one of unusually tight construction, provide adequate
combustion air by one of the methods described in applica-
ble 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, be-
tween 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 mate-
rials, gasoline and other flammable vapors and liquids.
Installing The Gas Line
1. The gas line must be installed before finishing the 24VF Fireplace.
Propane Gas requires a minimum inlet gas supply pressure of 35
mbar W.C. & a manifold pressure of 24 mbar 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
2. 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 3.5 kPa.
3. 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 3.5 mbar.
4. Determine that the gas pressure does not exceed 3.5 mbar and/or
check the corresponding minimum inlet ratings. Once the gas ratings
are determined adequate and the system does not leak, then connect
-11
the gas appliance and retest gas pressure for a total system leakage
by meter measuring at the gas valve pressure measuring port. If leaks
are determined, then repair and repeat the pressure test procedure.
5. Turn main gas control pilot knob OFF during any pressure testing.
Test pressure should be equal to or less than 3.5 kPa to prevent dam-
age to control valve.
6. Installation requirements and combustion and ventilation air provi-
sions must conform with local codes.
7.Keep the operating area clear and free of: combustible materials,
gasoline, or any vapours that would be flammable.
8. Never install a fireplace in a bathroom, recreational vehicle, high
traffic areas, windy or draft areas, or where flammable objects, such
as curtains, furniture or clothing, are less than 1 meter from the front
of the fireplace.
9. Due to high temperatures, the appliance should be located out
of traffic and away from furniture and draperies.
10. Children and adults should be alerted to the hazard of high
surface temperatures and should stay away to avoid burns or
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.
