Because our infrared gas heaters are gas appliances, it is not necessary that they be listed by UL (a nationally recognized testing laboratory – NRTL); however, all of the electrical component parts are UL listed (e.g., the draft inducer motors, which are equipped with CSA and UL approved thermal protectors). Our heaters are certified by C.S.A. (a nationally recognized testing laboratory – NRTL) and carry the C.S.A. seal. All heaters are tested and meet or exceed all safety requirements set forth in American National Standard Z83.20 for infrared heaters.

Generally, Factory Mutual certification (a nationally recognized testing laboratory – NRTL) is applicable to products that cannot be certified at the manufacturer’s facility according to American National Standard and, therefore, need to be certified at the installation site. Our heaters are certified by C.S.A.(a nationally recognized testing laboratory – NRTL) and carry the CSA seal. All heaters are tested and meet or exceed all safety requirements set forth in American National Standard Z83.20. Factory Mutual recognizes C.S.A. certification.

This is inaccurate for complete building heating. Infrared heaters heat people, the floor slab and machinery first, but since infrared uses all methods of heat transfer (radiation, re-radiation, conduction and convection), the air is heated secondarily as it passes over the warm concrete. Therefore, the heaters can be controlled by air temperature sensing thermostats.

Space-Ray infrared gas heaters are manufactured by Gas-Fired Products, Inc., which was founded in 1949 and has been manufacturing infrared heaters since 1958. Our heaters are certified by C.S.A (a nationally recognized testing laboratory – NRTL) and carry the CSA seal. All heaters are tested and meet or exceed all safety requirements set forth in American National Standard Z83.20.

The heater model and capacity are not necessarily a function of the square footage of the area needing to be heated. The model generally is chosen after the Btu/hr heat loss for the building or spot area to be heated has been determined, which is a function of not only the size of the area, but geographic location, building materials, building usage and other factors. Area coverage could be as little as 500 sq. ft. or as much as 10,000 sq. ft.

You may not use gas-fired infrared heaters inside paint booths or in buildings where explosion-proof lights are required. Although infrared is not ideal as an air curtain, it is very effective in spot-heating work areas inside of doorways, in dock areas and on outdoor docks.

Space-Ray infrared heaters have been mounted as low as 8′ above the finished floor (in home garages and workshops) to as high as 70′ (in high bay aircraft hangars). The mounting height depends on the Btu/hr capacity and model of the heater. Please refer to the heater’s specification sheet for minimum recommended mounting height and required clearances to combustible materials.

Primarily, the heater is controlled by a line voltage thermostat. Alternatively, you may use a 24-volt thermostat with a relay kit or an on/off switch.

Our N7 model is our standard two stage heater that requires a wired control to operate with a remote. Retro fit kits are available for previously purchased N7 heaters already in the field. The N10 model comes standard with a factory installed remote.

For new installations and orders, if you or your customer would like a remote control, please order the N10 or L10 models with our factory installed remote.Do not order the N7 or L7 model and add the remote kit. The remote kit is purely an after-install retro fit option.

The N10/L10 comes “remote ready” (pre-wired) and includes the handheld remote. You do not have to purchase the remote separately.You will receive (1) remote for each heater ordered. For example, if you order (5) heaters you will receive (5) remotes, (1) for each heater.

Our remotes are universal and do not have individual frequencies. If you or your customer purchases multiple heaters any of the remotes in your order will work with any of your heater’s receivers.You must however, individually point/aim (any one of) the remotes received in your order at each individual heater’s receiver and push the desired button for the heater to respond. They will not be synced/ zoned, so if you actuate one heater the others will not respond until you point/aim the remote at that unit’s unique receiver and press a button.

The remote from one heater cannot control another heater without being pointed/aimed at another heaters receiver. The remote must have a direct line of sight to the heater’s receiver to function. The remote’s signal cannot penetrate solid objects. If you point the remote at the heater’s receiver that you want to control, it should not actuate/ control any other heater.To control another heater with this remote you will have to point/aim the remote at the other heater’s receiver.This will make it very hard if not impossible to accidently control another heater.

Air-free CO emission levels are 0.0010 – 0.0020%, or 20 to 40 times lower than the maximum acceptable level as indicated in American National Standard Z83.20. Space-Ray utilizes burners that are made of heavy duty cast iron and are designed to enhance maximum primary and secondary air flow around the venturi assembly. The high velocity of the flame and the delayed flame-quench period minimize the products of combustion which include aldehyde, formic acid, nitrous oxide, and carbon monoxide.
