SECTION 3: CRITICAL CONSIDERATIONS
3.1 Minimum Required Clearances to Combustibles
Clearances are the required distances that combustible
objects must be kept away from the heater to prevent
serious fire hazards. Combustibles are materials, which
may catch on fire and include common items such as
wood, paper, rubber, fabric, etc. Maintain clearances to
combustibles at all times for your safety.
Clearances for all heater models are located on Page 4,
Figure 2 through Page 7, Figure 15 in this manual. Check
the clearances on each burner for the model heater being
installed to make sure the product is suitable for your
application and the clearances are maintained. Read and
follow the safety guidelines below:
• Keep petrol or other combustible materials including
flammable objects, liquids, dust or vapours away from
this heater or any other appliance.
• Maintain clearances from heat sensitive material,
equipment and workstations.
• Maintain clearances from vehicles parked below the
heater.
• Maintain clearances from swinging doors, overhead
cranes, vehicle lifts, partitions, storage racks, hoists,
etc.
• In locations used for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to maintain
required clearances from the heater to the combusti-
bles. Signs must be posted adjacent to the heater
thermostat. In the absence of a thermostat, signs
must be posted in a conspicuous location.
• Consult local Building Inspector, Fire Insurance
Carrier or other authorities for approval of proposed
installation when there is a possibility of exposure to
combustible airborne materials or vapours.
• Hang heater in accordance to the minimum suspen-
sion requirements on Page 9, Section 4.6 through
Page 9, Section 4.8.
• If the radiant tubes must pass through the building
structure, be sure that adequate sleeving and fire
stop is installed to prevent scorching and/or fire
hazard.
