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 a fire hazard. Combustibles are materials
that may catch on fire and 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
equipment.
• Do not spray aerosols in the vicinity of this
heater.
• 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.
• Maintain clearances from heat sensitive
equipment and workstations.
• Consult local Fire Marshal, 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 7, Figure
3. If clearances to combustibles are not indicated,
then installation clearances apply.
WARNING
Fire Hazard
Keep all flammable objects, liquids and
vapours the minimum required clearances to
combustibles away from heater.
Some objects will catch fire or explode when
placed close to heater.
Failure to follow these instructions can result
in death, injury or property damage.
