SECTION 4: CLEARANCES TO COMBUSTIBLES
4.1 Required Clearances to Combustibles
Clearances are the required distances that
combustible objects must be away from the heater
to prevent fire hazard. Combustible material that
may catch fire include common items such as wood,
paper, rubber, fabric, etc. Maintain clearances to
combustibles at all times for safety.
Clearances for all heater models are located on the
serial plate of the heater and throughout the manual.
Check the clearances on the serial plate to make
sure the product is suitable for your application and
the clearances are maintained. Read and follow the
safety guidelines below:
• Keep gasoline or other combustible material
including flammable objects, liquids, dust or
vapors away from this heater or any other
appliance.
• The stated clearances to combustibles
represents a surface temperature of 90° F
(50° C) above room temperature. Building
materials with a low heat tolerance (such as
plastics, vinyl siding, canvas, tri-ply, etc.) may be
subject to degradation at lower temperatures. It
is the installer's and owner's responsibility to
assure that adjacent materials are protected
from degradation.
• Consult local Fire Marshall, Fire Insurance
Carrier or other authorities for approval of
proposed installation when there is a possibility
of exposure to combustible airborne materials or
vapors.
4.2 Clearances to Combustibles
Clearances must be as indicated on Page 6, Figure
3. If clearances to combustibles are not indicated,
then installation clearances apply.
