|MODEL||BTU/HR INPUT||MINIMUM MOUNTING HEIGHT|
* Minimum recommended mounting heights are intended as a guide only, as heaters may be mounted at various heights and angles. Mount heaters as high as possible. Minimums are shown as a guideline for human comfort and uniform enrgy distribution for complete building applications. Please consult your Space-Ray Representative for a detailed analysis of your particular heating requirements.

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.

NOTE: For all installations higher than 2000 ft. above sea level please consult the factory regarding recommended derating of heaters.
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”.
Heaters can be common vented, vented or indirect vented. A vented installation must be vented outside the building with a flue pipe. An indirect vented installation 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 and service must be performed by a licensed contractor. The installation must conform to written Installation & 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 CSA 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.
Outdoor Kit – Part # 42411000
Outdoor Kit ( Part # 42411000) is required when the heater is installed outdoor with no protective cover or overhang. The kit includes Inlet Air Hood as well as Exhaust Hood. Outdoor Kit Installation Instructions (PDF)
