2.0 INSTALLATION

Provide adequate ventilation and combustion air, see "COmbusTION aNd vENTIlaTION aIr
PrOvIsIONs" section. Provide adequate accessibility clearance for servicing and operating the heater.
Never obstruct the front opening of the heater.
As long as clearance to combustibles is kept within the required distances, the most desirable and beneficial
location for a heater is in the centre 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 heater is to be located should be
considered.
maintain these minimum clearances to combustibles:

COmBuSTION ANd vENTILATION AIr prOvISIONS

This heater 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 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 communi-
cating 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 GVFS60 is rated at 30,000 BTUs per hour and therefore requires a minimum unconfined space of 1,500
cubic feet.
