Clearances are the required distances that combustible 
objects must be away from the heater to prevent fire 
hazards. Caution should be used when running the 
system near combustibles. 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 Page 6, 
Figure 3 through Page 9, Figure 16 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.

• The stated clearances to combustibles represents a 

surface temperature of 32°C (90° F) above room tem-
perature. 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 responsibility to assure that adja-
cent materials are protected from degradation.

• Maintain clearances from heat sensitive  equipment 

and workstations.

• Maintain clearances from vehicles parked below the 

heater.

• Maintain clearances from swinging and overhead 

doors, overhead cranes, vehicle lifts, partitions, 
storage racks, hoists, building construction, etc.

• In locations used for the storage of combustible mate-

rials, signs must be posted to specify the 
maximum permissible stacking height to maintain 
required clearances from the heater to the 
combustibles. 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 

suspension requirements on Page 11, Section 5.
