THIS GAS HEATER SHOULD BE INSTALLED AND SERVICED BY A QUALIFIED INSTALLER to conform
with local codes. Installation practices vary from region to region and it is important to know the specifi cs that
apply to your area.
Provide adequate ventilation and combustion air. Provide adequate accessibility clearance for servicing
and operating the heater. Never obstruct the front opening of the heater.
As long as clearances to combustibles is kept within the required distances, the most desirable and benefi cial
location for a heater is in the centre of a building, thereby allowing the most effi cient use of the heat created.
The location of windows, doors and the traffi c fl ow in the room where the heater is to be located should be
considered.
MAINTAIN THESE MINIMUM CLEARANCES TO COMBUSTIBLES:
A. 4" B. 2"* C. 2"
Heater should not be installed directly on carpeting.
Minimum 48" from top to ceiling.
* If less than 5" clearance is maintained between the back of the heater and the back wall, it will be necessary
to disconnect the gas pipe to move the heater out for installation or service of the blower.
3.0 INSTALLATION
3.1 COMBUSTION AND VENTILATION AIR PROVISIONS
17.1A
This appliance shall not be installed in a confi ned 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 defi nes a confi ned 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 unconfi ned 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 unconfi ned space.
The GVFS20 is rated at 23,000 BTU's per hour for natural gas and propane gas and therefore requires a
minimum unconfined space of 1,150 cubic feet.
