Floor Level Coverage - The above chart may be used as a guideline for primary radiation, i.e. the infrared pattern directly below the heater. In a well-insulated building, only 50% of the floor needs to be covered by the primary radiant pattern. Please be aware that the radiant energy generated by infrared heaters is not limited to the primary radiant pattern. There is additional radiant energy that is absorbed outside the primary area, a secondary radiant pattern. Since concrete is a very good conductor of heat, a reasonably uniform floor temperature eventually will be reached. The amount of time it takes to reach "thermal equilibrium" is in direct correlation to the distance between the heaters. Learn More >>

NOTE:: The clearances specified above must be maintained to combustibles and other materials that may be damaged by temperatures 90°F above ambient temperature. Clearances to combustibles are posted on the reflector near the control end of the heater. In locations used for storage of combustible materials where they may be stacked below the heater, NFPA 54 requires that the installer must post signs that will "specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles".

VENTING REQUIREMENTS
This is an indirect vented heater and requires a minimum ventilation flow of 4 CFM per 1000 BTU/hour of total installed heater capacity on natural gas by either gravity or power ventilation (4.18 CFM per 1000 BTU/hour on propane).

INSTALLATION REQUIREMENTS
Installation and service must be performed by a licensed contractor. The installation must conform to written Instalation & Operating Instructions and local codes. In the absence of local codes, the installation must conform with the National Fuel Gas code, ANSI Z223.1 (latest edition also known as NFPA54) or GCA B149 (latest edition) installation codes. These codes are available from the National Fire Protection Association, Inc., Batterymarch Park, Quincy, MA 02269 or the Canadian Gas Association, 55 Scarsdale Road, Toronto, Ontario M3B 2R3, CANADA.

FOR YOUR SAFETY
Operate infrared heaters with proper care and observe all safety precautions. Carefully follow printed installation, operating and cleaning instructions furnished with the heater. Do not store gasoline or combustible products in the vicinity of the heater. Do not touch the heater or the tubes while the heater is in operation. Adequate ventilation must always be provided in accordance with codes.

Parabolic Reflector Extension

The Parabolic Reflector Extension is used to increase the intensity of the heater by focusing inrared energy in a narrower area for spot heating applications. Details on Parabolic Reflector Extension Kit (PDF)
