    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 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. For indoor installation only. Not for use in residential dwellings.

  • 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.

    14.0) VENTING This is a category lll appliance. A. BASIC FLUE VENTING — Venting must comply with the latest edition of the National Fuel Gas Code (ANSI Z223.1-latest edition) or the authority having jurisdiction. Other venting references are in the equipment volume of the ASHRAE Handbook.
  • Page 39 SINGLE HEATER VENTING (HORIZONTAL THROUGH SIDEWALL) When venting the heater horizontally through a combustible outside sidewall, the same requirements listed previously for venting Vertical Through The Roof apply except as follows: 40. A vent passing through a combustible wall must pass through an approved clearance thimble (Air-Jet #4VT or Ameri-Vent #4EWT or other thimbles) that are listed by a nationally recognized testing agency;...
  • Page 40 45. A minimum clearance of 6 inches must be maintained between the outside wall and vent cap (18” clearance will provide stability under high wind conditions). 46. The horizontal venting system shall not terminate: • Less than 4 ft. (1.2m) below, 4 ft. (1.2m) horizontally from or 1 ft. (30cm) above any door, operable window or gravity air inlet into any building.
  • Page 41 MULTIPLE HEATER VENTING (CONNECTIONS INTO A COMMON VENT OR MANIFOLD) Requirements for venting of multiple heaters are the same as described for SINGLE HEATER VENTING except as follows: 48. The common vent size and total vent height is normally determined by the number of heaters per common vent, length of horizontal connector runs, and connector fall.

    B. INDIRECT VENTING (UNVENTED HEATERS) — This heater requires ventilation in the building to dilute the products of combustion and provide fresh air for efficient combustion. Where unvented heaters are used, gravity or mechanical means shall be provided to supply and exhaust at least 4 CFM per 1,000 Btu/hr input of installed heaters.
  • Page 44 In multiple heater applications, the combustion air intake may be ducted individually or common ducted in the same configuration as shown for venting in Section 14.0). For combustion air intake duct sizing, please refer to the Vent Sizing Table and use the diameter indicated, based on the number of heaters per duct. All vent terminations and Combustion Air Intake Terminations must be at least 6”...

  • Page 45: Lighting And Shutdown Instructions

    16.0) LIGHTING AND SHUTDOWN INSTRUCTIONS 53. Turn on the gas and electrical supply. 54. Set the thermostat to call for heat. The blower motor will energize. 55. Ignition should occur after the 15-second pre-purge. 56. If the burner fails to light, or flame is not detected during the first trial for ignition (a period of approximately 15 seconds) the gas valve is de-energized and the control goes through an inter-purge delay of approximately 60 seconds before another ignition attempt.
  • Page 46 Note: When the PGR is operated by a thermostat interrupting the line voltage (120V) to the heater then the post purge function is disabled. If the flame is not sensed during sequence T3 then the burner will automatically begin re-ignition sequence T2. The ignition sequence will be repeated three times with a 60 second inter-purge.

    IGNITION MODULE DIAGNOSTICS Flame Fault If at any time the main valve fails to close completely and maintains a flame, the full time flame sense circuit will detect it and energize the combustion blower. Should the main valve later close completely removing the flame signal, the combustion blower will power off following the post purge period.
