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).
When installed with a blower the junction box must be electrically connected and grounded in accordance
with local codes. In the absence of local codes, use the current ANSI / NFPA 70 National Electric Code. In
the case where the blower is equipped with a power cord it must
be connected into a properly grounded receptacle. The grounding
prong must not be removed from the cord plug.
As long as the required clearance to combustibles is maintained,
the most desirable and beneficial location for the appliance is in
the center of a building, thereby allowing the most efficient use of
the heat created. The location of windows, doors and the traffic
flow in the room where the appliance is to be located should be
considered.
If the appliance is installed directly on carpeting, vinyl tile or other combustible material other than wood
flooring, the appliance shall be installed on a metal or wood panel extending the full width and depth. NOTE:
This does not apply to stoves.
* Air shortage caused by an inadequate air supply, improper log positions, the addition of foreign or
unapproved materials or the failure to properly maintain the appliance, may result in incomplete combustion of

3.0 INSTALLATION
To determine the volume o
f
the room where the appliance is to be installed, multiply the width x the length x
the ceiling height of that room measured in feet. If any adjoining rooms are connected by grilles or openings
such as kitchen pass-throughs, etc., the volume of those rooms may be added to the total.
Multiply the room volume by 1000 and divide this amount by 50 to determine the maximum BTU/hr that the
space can support with adequate combustion and ventilation air.
A
dd the Btu/hr of all fuel burning appliances located within the space such as gas furnace, gas water
appliance, etc. Do not include direct vent gas appliances which draw their input and output air from and to the
outdoors.
Unusually tight construction is defined as construction where:
A) Walls and ceilings exposed to the outside atmosphere have a continuous water vapour retarder with a
rating of 1 perm (6 x 10-11 kg per pa-sec-m2) or less with openings gasketed or sealed, and
B) Weather stripping has been added on openable windows and doors, and
C) Caulking or sealants are applied to areas such as joints around window and door 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.
A
n unvented room appliance is recommended for use as a secondary heat source rather than as a primary
source. Gas combustion produces water vapour which could occur at the rate of approximately one ounce of
water for every 1,000 BTU/hr of gas input. During the cold weather season, indoor humidity levels tend to be
low. Consequently, this water vapour can enhance the living space. However if a problem should occur:
A) Ensure sufficient combustion and circulation air
B) Use a dehumidifier
C) Do not use the unvented room appliance as a primary heat source
Without sufficient fresh air for proper operation, poor fuel combustion can result. Carbon Monoxide is a result
of poor combustion.
If additional fresh air is required, use one of the methods described in the National Fuel Gas Code, ANSI
Z223.1 / NFPA54 or the applicable local code.
!
WARNING
IF THE AREA IN WHICH THE APPLIANCE MAY BE OPERATED IS SMALLER THAN THAT DEFINED AS
AN UNCONFINED SPACE OR IF THE BUILDING IS OF UNUSUALLY TIGHT CONSTRUCTION, PROVIDE
ADEQUATE COMBUSTION AND VENTILATION AIR BY ONE OF THE METHODS DESCRIBED IN THE
NATIONAL FUEL GAS CODE ANSI Z223.1/ NFPA 54 ,AIR FOR COMBUSTION AND VENTILATION, OR THE
APPLICABLE LOCAL CODE.
IF THE AREA IN WHICH THE APPLIANCE MAY BE OPERATED DOES NOT MEET THE REQUIRED VOLUME
FOR INDOOR COMBUSTION AIR, COMBUSTION AND VENTILATION AIR SHALL BE PROVIDED BY ONE
OF THE METHODS DESCRIBED IN THE ANSI Z223.1 / NFPA 54, THE INTERNATIONAL FUEL GAS CODE,
OR APPLICABLE LOCAL CODES.
17.1A
This appliance shall not be installed in a confined space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air.
The National Fuel Gas Code, ANSI Z223.1 / NFPA 54 defines a confined space as a space whose volume is
less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances
installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per
1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space.
Rooms communicating directly with the space in which the appliances are installed, through openings not
furnished with doors are considered a part of the unconfined space.
The GVF42 is rated at 30,000 BTUs per hour for natural gas and 30,000 BTUs for propane and therefore re-
quires a minimum unconfined space of 1,500 cubic feet.

EXAMPLE 2:
If in this example a solid door separates Room 1 from Room 2, the volume of Room 2 could not be used. In
this case the maximum BTU/h would be:
Maximum BTU/h: 800x1000 = 16,000 BTU/h
50
19.1B
Room Volume = Length x Width x Height
Max BTU/hr = Room Volume x 1000 / 50

HEIGHT
ROOM 2
ROOM 1
WIDTH
If for example:
The length of the rooms is 10 feet,
The width of Room 1 is 10 feet,
The width of Room 2 is 15 feet,
The height of the rooms is 8 feet.
The volume of Room 1: 10x10x8 = 800 cubic feet
The volume of Room 2: 10x15x8 = 1200 cubic feet
19.2
EXAMPLE 1:
In this example, because there is no door to the adjoining room, the volume of the adjoining room may be
added to the volume of the room with the heater to get a total unconfined space.
The total unconfined space: 800 + 1200 = 2000 cubic feet.
Maximum BTU/h: 2000x1000 = 40,000 BTU/h
50
If there are no more fuel burning appliances within this space then the 30,000 BTU/h input of the appliance is
suitable to be installed. This also assumes that the construction of this space is not unusually tight.
This would be considered a confined space since it can not support the 30,000 BTU/h input of the appliance
and it would be necessary to provide adequate combustion and ventilation air to Room 1.
