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 and
servicing. Minimum clearances to combustibles must
be maintained as shown in the following figures.
Ensure you consider the need for access to the gas
control valve, gas piping, as well as full access for
periodic cleaning and servicing.
