SECTION 3: CLEARANCES TO COMBUSTIBLES 3.1 Required Clearances to Combustibles

Clearances are the required distances that combusti- ble objects must be 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 safety.

Clearances for all heater models are located on the burner assembly and on Page 6, Figure 3 through Page 8, Figure 10 in this manual. Check the clear- ances 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 gasoline or other combustible materials including flammable objects, liquids, dust or vapors away from this heater or any other appli- ance.

•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, can- vas, tri-ply, etc) may be subject to degradation at lower temperatures. It is the installer’s responsibil- ity to assure that adjacent 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 materials, signs must be posted to specify the maximum permissible stacking height to maintain required clearances from the heater to the com- bustibles. Signs must be posted adjacent to the heater thermostat. In the absence of a thermo- stat, signs must be posted in a conspicuous loca- tion.

•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.

•Hang heater in accordance to the minimum sus- pension requirements.

•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.

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.
