SECTION 3: CLEARANCES TO COMBUSTIBLES

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.

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, which 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 around the heater and flue must be as indicated on Page 6, Figure 3, to ensure access for servicing, and correct operation. If clearances to combustibles are not indicated, then installation clearances apply.

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 appli- ance.

The stated clearances to combustibles repre- sents a surface temperature of 32°C (90° F) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl sid- ing, canvas, tri-ply, etc) may be subject to degra- dation at lower temperatures. It is the installer’s responsibility to assure that adjacent materials are protected from degradation.

Maintain clearances from heat sensitive equip- ment and workstations.

Maintain clearances from vehicles parked below the heater.

Maintain clearances from swinging and over- head doors, overhead cranes, vehicle lifts, parti-

tions, storage racks, hoists, building construction, etc.

In locations used for the storage of combustible materials, signs must be posted to specify the maximum permissible stacking height to main- tain required clearances from the heater to the combustibles. Signs must be posted adjacent to the heater thermostat. In the absence of a ther- mostat, signs must be posted in a conspicuous location.

Consult local Building Inspector, Fire Insurance Carrier or other authorities for approval of pro- posed 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 10, Section 6 and Page 11, Figure 4 through Page 12, Figure 5.

Affix the tag on a wall near the heater.
