SECTION 3: CLEARANCES TO COMBUSTIBLES

WARNING

Fire Hazard

Keep all flammable objects, liquids and vapors 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.

3.1 Required Clearances to Combustibles

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.
