Introduction. Welcome to the new range of powered infra-red heaters. Local regulations may vary and it is the installer’s responsibility to ensure that such regulations are satisfied. heaters specified in these instructions, due care and attention is required to ensure that working at height regulations are adhered to.
F. installed in accordance with the Standard for Parking Structures, ANSI/NFPA 88A, or the Standard for Repair Garages, ANSI/NFPA 88B, or the Canadian Natural Gas and Propane Installation Code, CSA B149.1, and are so marked. Ensure that minimum clearances will be maintained to vehicles parked below the heater. purpose made to sound engineering practice or supplied by others. The standard heaters are approved for installations between 0 - 2000ft (0 610m) for the US and 0 - 4500 ft (1370m) for Canada.
Minimum clearance to combustibles are shown in Figure 2. Refer to table 1 below. Building material with a low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to degradation at lower temperatures. IMPORTANT: The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room temperature. It is the installer’s responsibility to assure that adjacent materials are protected from degradation. 1.3 Clearance to Combustibles.
