Locations and Clearances
The location of the Furnace is normally selected by the
architect, the builder, or the installer. However, before
the Furnace is moved into place, be sure to consider
the following requirements:
1. Is the location selected as near the chimney or vent
and as centralized for heat distribution as practical?
2. Do all clearances between the Furnace and
enclosure equal or exceed the minimums stated in
Clearance Table below?
Minimum clearance to combustible materials
INSTALLATION CLEARANCE TO COMBUSTIBLE CONSTRUCTION
NOTES:
FOR VERTICAL APPLICATIONS
FOR HORIZONTAL APPLICATIONS
3. Is there sufficient space for servicing the Furnace
and other equipment? A minimum of 24 inches
front accessibility to the Furnace must be provided.
Any access door or panel must permit removal of
the largest component.
4. Are there at least 3 inches of clearance between the
Furnace combustion air openings in the front panel
and any closed panel or door provided?
5. Are the ventilation and combustion air openings
large enough and will they remain unobstructed? If
outside air is used, are the openings set 12" above
the highest snow accumulation level?
