2.3 National Standards and Applicable Codes All appliances must be installed in accordance with the latest revision of the applicable standards and national codes. This refers also to the electric, gas and venting installation. Note: Additional standards for installations in public garages, aircraft hangars, etc. may be applicable. SECTION 3: CRITICAL CONSIDERATIONS 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 fire hazards. Combustible materials that may catch fire 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 appliance. • Maintain clearances from heat sensitive material, 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 . 1"2". , '4# #"#! - 5 !

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 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 suspension requirements on Page 10, Figure 12. • 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. NOTE: 1. All dimensions are from the surfaces of all tubes, couplings and elbows. 2. Clearances B, C and D can be reduced by 50% after 25' (7.5 m) of tubing downstream from where the burner and burner tube connect.
