Combustion Air and Ventilation
Combustion air and venting requirements for all gas-fired heating equipment must be provided per the National Fuel Gas Code
NFPA54 or the authority having jurisdiction over the installation. In contaminated atmospheres or high humidity areas, optional
outside air for combustion can be supplied. Heaters can be common vented, vented, or indirect vented. Refer to the Installation
and Operation Instructions for further information. A vented installation must be vented to the outside of the building with a flue
pipe. An Indirect vented installation requires a minimum ventilation flow of 4 CFM per 1000 Btu/hr of total installed heater capacity
on natural gas by either gravity or power ventilation (4.18 CFM per 1000 Btu/hr for propane). For indirect vented applications,
building exhaust openings must be located above the level of the heaters and inlet air openings must be located below the level of
the heaters.
For Your Safety
OPERATE GAS INFRARED HEATERS WITH PROPER CARE AND OBSERVE ALL SAFETY PRECAUTIONS. Installation and service
must be performed by a licensed contractor. The installation must conform to Manufacturer's Installation and Operating
Instructions or local codes. In the absence of local codes, the installation must conform to the National Fuel Gas Code ANSI
Z223.1 (latest edition, also known as NPFA54) or CAN / CSA-B149 installation codes (latest edition).

LOW INTENSITY INFRARED HEATERS
This chart is intended as a guide only, as heaters may be mounted at various heights and angles. Since straight tube heaters are always hotter at the burner
end than at the exhaust end, always observe the minimum recommended mounting heights shown above and mount heaters as high as possible. Use RSU
series for spot heating. Please consult your local Representative for a detailed analysis of your particular infrared heating requirements.

* When used indirect vented, clearances to ceiling must be: 12" for RSS/U (50-75), and 18" on RSS/U (100-200). If optional corner or U-bend reflectors
are not used, the clearance must be 18".
** Minimum clearance below reduces by 50% once you are 25 ft. downstream from the burner box.
Note: Consult factory if reduced clearances are required.
