SECTION 3: CRITICAL CONSIDERATIONS 3.1 Required Clearances to Combustibles

Clearances are the required distances that combustible objects must be away from the heater to prevent serious fire hazards. 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 the burner of the heater and on Page 3, Figure 1 through Page 6, Figure 10 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 gasoline or other combustible materials including flammable objects, liquids, dust or vapors away from this heater or any other appli- ance.
