Clearances to Combustibles
Note: Ensure clearances are in accordance
with local installation codes and the
requirements of the gas supplier.
Clearance to Combustibles
Due to high surface temperatures, locate the unit out
of traffic areas and away from furniture and
draperies. Do not place clothing and other
flammable material on or near the heater. When
positioning the unit always maintain adequate
clearances around air openings into the combustion
chamber and allow for adequate ventilation.
Minimum clearances to combustibles must be
maintained as shown in Figures 3 - 6.
Note:
The rear clearance to combustibles is
determined by either the unit’s or the vent pipe’s
minimum clearance, depending on whether the
installation calls for vertical rise within the room or a
rear exit, through-the-wall vent pipe.
Ensure you consider the need for access to the gas
control valve access door on the front of the unit as
well as full access for periodic cleaning and
servicing. Also consider clearance for the blower
assembly if present, or planned in the future.
CAUTION: THESE CLEARANCES REPRESENT
MINIMUM DISTANCES IN ALL CASES, WHICH,
THROUGH TESTING IN AN INDEPENDENT
LABORATORY TO ANSI AND CSA STANDARDS,
WILL PREVENT FIRE OR SPONTANEOUS
COMBUSTION. WE DO NOT CONTROL THE
COMBUSTIBLE MATERIALS EXPOSED TO HEAT
