!
Installation and repair should be done by a qualified service person. The heater should be inspected before use and at least
annually by a qualified service person. More frequent cleaning may be required as necessary. It is imperative that the
control compartment, air passageways and burner of the heater be kept clean.
!
Heaters intended for use at high altitude should be de-rated for optimum performance. Check the heater rating plate to be
sure that the heater has been de-rated. (The statement
“This appliance equipped for high altitude elevation 2,000 to 4,500
feet”
should appear on the rating plate if it has been de-rated at the factory.) If the heater has not been de-rated, contact
the factory for the necessary high-altitude conversion kit(s).
INSTALLATION REQUIREMENTS
The installation must conform to local building codes or, in the absence of local codes, with the National Fuel Gas Code ANSI
Z223.1/NFPA54 or the Natural Gas And Propane Installation Code CSAB149.1. Heaters shall be installed by a licensed
contractor or licensed installer. Clearances to combustibles as outlined in this manual should always be observed. In areas
used for storage of combustible materials where they may be stacked below the heater, NFPA54 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.”
Every heater shall be located with respect to building construction and other equipment so as to permit access to the heater.
Each installer shall use quality installation practices when locating the heater and must give consideration to clearances to
combustible materials, vehicles parked below, lights, overhead doors, storage areas with stacked materials, sprinkler heads,
gas and electrical lines, and any other possible obstructions or hazards. Consideration also must be given to service accessibility.
The heater, when installed in aircraft hangars and public garages, must be installed in accordance with ANSI/NFPA 409-latest
edition (Standard for Aircraft Hangars), ANSI/NFPA 88a-latest edition (Standard for Parking Structures), and ANSI/NFPA 88b-
latest edition (Standard for Repair Garages) with the following clearances:
a. At least 10 feet above the upper surfaces of wings or engine enclosures of the highest aircraft that may be housed in the
hangar and at least 8 feet above the floor in shops, offices, and other sections of hangars communicating with aircraft
storage or service areas.
b. At least 8 feet above the floor in public garages.
S
WARNING:
Minimum clearances marked on the heater must be
maintained from vehicles parked below the heater.
a. Installation of this appliance is to be in accordance with latest edition of CAN 1-B149.1 (Installation Code for Natural Gas
Burning Appliances and Equipment), and/or CAN B149.2 (Installation Code for Propane Gas Burning Appliances and
Equipment).
b. For installation in public garages or aircraft hangars, the minimum clearances from the bottom of the infrared heater to
the upper surface of the highest aircraft or vehicle shall be 50 percent greater than the certified minimum clearance, but
the clearance shall not be less than 8 feet.
Although these heaters may be used in many applications other than space heating (e.g., process heating), SPACE-RAY will
not recognize the warranty for any use other than space heating.
This heater is for Indoor Installation only and can be used in Unvented mode. The term Unvented actually means Indirect
Vented. While the products of combustion are expelled into the building, national codes require ventilation in the building to
dilute these products of combustion. This ventilation may be provided by gravity or mechanical means.
This heater is not an explosion proof heater.
Where the possibility of exposure to volatile and low flash point materials
exists, it could result in property damage or death. This heater must not be installed in a spray booth where the heater can
operate during the spraying process. Consult your local fire marshal or insurance company.
S
WARNING:
Certain materials or objects, when stored under the heater will be subjected to radiant heat and could be
seriously damaged.
Observe the MINIMUM CLEARANCES TO COMBUSTIBLES listed in this manual and on the heater
at all times.
