INSTALLATION AND OPERATION INSTRUCTIONS
OWNER / INSTALLER: For your safety this manual must be carefully and thoroughly read and understood before
installing, operating or servicing this heater. This heater is intended for use with either Natural Gas or Propane
Gas. It must be installed by a qualified service person or a licensed contractor in accordance with state and local
codes.
: Improper installation, adjustment, alteration, service, or maintenance can cause property
damage, injury or death. Read the installation, operation and maintenance instructions thoroughly before
installing or servicing this heater. For assistance or additional information, consult a qualified installer, service
agency or the gas supplier.
For Indoor Installations INSPECT all combustion air openings into the building and, if necessary, clear if they
become blocked.
FOR YOUR SAFETY: If this heater is installed indoors, it must be in a sufficiently ventilated space. Exhaust fans
MUST be operating on an appropriate cycle when heaters are operating to avoid a high concentration of carbon
monoxide. When installed in insufficient ventilated spaces this heater may give off carbon monoxide, an odorless
and poisonous gas. CARBON MONOXIDE POISONING MAY LEAD TO DEATH. Early signs of carbon monoxide
poisoning resemble the flue with headaches, dizziness and nausea. If you experience these signs, GET FRESH AIR
IMMEDIATELY! Have the heaters serviced as soon as possible and check the ventilation into the building.
INSTALLER: This manual is the property of the owner. Please present this manual to the owner when you leave
the job site.
IF YOU SMELL GAS:
1. Shut off gas to the appliance.
2. Extinguish any open flame.
3. If odor continues, keep away from the appliance
and immediately call your gas supplier.

    SAFETY This heater is a self-contained infrared radiant ceramic heater. Safety information required during installation and operation of this heater is provided in this manual and the labels on the product. The installation, service and maintenance of this heater must be performed by a contractor qualified in the installation and service of gas fired heating equipment.
  • Page 4 Consideration also must be given to service accessibility. Space-Ray will not recognize the warranty for any use other than space heating. Form 44201450 Oct 2018...

  • Page 5: Minimum Clearances To Combustibles

    This heater is for Indoor and Outdoor Installation and is used in Unvented mode. The term Unvented actually means Indirect Vented. While the products of combustion are expelled into the building, national codes require 4 CFM/1000 BTU of heater input ventilation in the building to dilute these products of combustion. This ventilation may be provided by gravity or mechanical means.
  • Page 6 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 the manual and on the heater at all times. For maximum safety the building must be evaluated for hazards before installing the heater system. Examples include, but are not limited to: ...
  • Page 7 “specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles.” Space-Ray recommends posting these signs adjacent to the heater thermostat or other suitable location that will provide enhanced visibility.

  • Page 8: Indoor Clearances To Combustibles

    INDOOR CLEARANCES TO COMBUSTIBLES The stated clearance to combustibles represents a surface temperature of 90º F (50º C) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to assure that adjacent materials are protected from degradation.

  • Page 9: Outdoor Clearances To Combustibles

    OUTDOOR CLEARANCES TO COMBUSTIBLES The stated clearance to combustibles represents a surface temperature of 117º F (65º C) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to assure that adjacent materials are protected from degradation.
