FOR YOUR SAFETY: If the heater is installed without a flue, exhaust fans MUST be operating on an appropriate
cycle when heaters are operating to avoid a high concentration of carbon monoxide. When used without fresh
air, 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:
FOR YOUR SAFETY
!DO NOT try to light any appliance.
!DO NOT touch any electrical switch; DO NOT use any
telephone in your building.
!IMMEDIATELY call your gas supplier from a neighbor's
telephone. Follow the gas supplier's instructions. If you
cannot reach your gas supplier, call the fire department.
DO NOT store or use gasoline or other
flammable vapors and liquids in the vicinity of
this or any other appliance.
!IMPORTANT: SAVE THIS MANUAL FOR FUTURE REFERENCE.

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.
All personnel in contact with the heater must read and understand all safety information, instructions and labels
before operation. The following symbols will be used in this manual to indicate important safety information.
Warning instructions must be followed to prevent or avoid hazards which
may cause serious injury, property damage or death.
Caution instructions must be followed to prevent incorrect operation or
installation of the heater which may cause minor injury or property
damage.
2.0) INSTALLER RESPONSIBILITY
The installer is responsible for the following:
•The heater and venting, as well as electrical and gas supplies must be installed in accordance with these
installation instructions and any applicable codes and regulations.
•Every heater shall be located with respect to building construction and other equipment so as to permit
access to the heater.
•Each installer must follow the clearances to combustible materials for the heaters.
•Install the heater so that the supports and hangers are correctly spaced in accordance with these
instructions. The heater must be supported by materials having a working load limit of at least 52kg.
•Supply the owner with a copy of these Installation and Operation Instructions.
•Never use the heater as a support for a ladder or other access equipment. Do not hang anything from the
heater.
•Supply all installation materials necessary that are not included with the heater.
•Check the nameplate to make sure that the burner is correct for the gas type in the building.
3.0) GENERAL INFORMATION
This heater is a self-contained infrared radiant tube heater designed for use where flammable gases or vapors
are not generally present.
Installation of this heater must be in accordance with all applicable codes shown in the instructions and/or the
local codes and authorities having jurisdiction. In the UK all equipment must be installed and maintained in
accordance with the relevant provisions of the Gas Safety (Installations and Use) Regulations 1998 for gas fired
products. Installation practices must take into account the Health and Safety at Works Act 1974 or relevant
codes of practice. In addition the installation must be carried out in accordance with the current IEE wiring
regulations BS 7671-latest revision, BS 6896-latest revision (Industrial & Commercial) and any other relevant
British Standards and Codes of Practice by a qualified installer. All external wiring MUST comply with the current
IEE wiring regulations.
Clearances to combustibles as outlined in the manual should always be observed. In areas used for storage of
combustible materials where they may be stacked below the heater, 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 control housing. Each installer shall use skillful and reliable installation practices when locating the
heaters and must give consideration to service accessibility.
This heater is for INDOOR INSTALLATION ONLY and is used in VENTED or 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 must be provided by
gravity or mechanical means. Ventilation requirements are addressed further in these instructions.
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 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.
Linear Configuration Series Only: Since linear configuration tube heaters are always hotter at the control end
than at the flue terminal end, always observe the minimum recommended mounting heights.

▲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 the manual and on the
heater at all times.
NOTE:
1. The clearances specified above must be maintained to combustibles and other materials that may be
damaged by temperatures 50ºC above ambient temperature. Clearances to combustibles are posted on the
control box. 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.” Space-Ray recommends posting these
signs adjacent to the heater thermostat or other suitable location that will provide enhanced visibility.
2. The stated clearance to combustibles represents a surface temperature of 50 ºC 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.
