    1.0) SAFETY This heater is a self-contained infrared radiant tube 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 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 and Covered Patio Installation only and can be used in either Vented or Unvented mode.

  • Page 5: Minimum Clearances To Combustibles

    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.” Space-Ray recommends posting these signs adjacent to the heater thermostat or other suitable location that will provide enhanced visibility.

    10.0) HEATER ASSEMBLY During field assembly of the heater, the recommended procedure is as follows: 1. Install suspension (according to Section 7.0) using proper suspension method (see Section 9.0). Trapeze Method Individual Suspension Method 2. Lift the tube section and suspend it into place. When lifting, caution should be used to avoid damaging the assembly.
