STERLING “RSS” SERIESINFRARED RADIANT TUBE HEATER1) GENERAL INFORMATIONThis heater complies with ANSI Z83.20 (currentstandard) and CSA 2-34.This heater is a self-contained infrared radiant tubeheater for use in locations where flammable gases orvapors are not generally present (as defined by OSHAacceptable limits) and is intended for the heating ofnonresidential spaces.INSTALLATION REQUIREMENTSThe installation must conform to local building codes or,in the absence of local codes, with the National FuelGas Code ANSI Z223.1/NFPA54 or the Natural Gasand Propane Installation Code CSAB149.1. Heatersshall be installed by a licensed contractor or licensedinstaller. Clearances to combustibles as outlined in thismanual should always be observed. In areas used forstorage of combustible materials where they may bestacked below the heater, NFPA54 requires that theinstaller must post signs that will “specify the maximumpermissible stacking height to maintain the requiredclearances from the heater to combustibles.”Every heater shall be located with respect to buildingconstruction and other equipment so as to permitaccess to the heater. Each installer shall use qualityinstallation practices when locating the heater andmust give consideration to clearances to combustiblematerials, vehicles parked below, lights, overheaddoors, storage areas with stacked materials, sprinklerheads, gas and electrical lines, and any other possibleobstructions or hazards. Consideration also must begiven to service accessibility.The heater, when installed in aircraft hangars andpublic garages, must be installed in accordance withANSI/NFPA 409-latest edition (Standard for AircraftHangars), ANSI/NFPA 88a-latest edition (Standard forParking Structures), and ANSI/NFPA 88b-latest edition(Standard for Repair Garages) with the followingclearances:a. At least 10 feet above the upper surfaces of wingsor engine enclosures of the highest aircraft thatmay be housed in the hangar and at least 8 feetabove the floor in shops, offices, and other sectionsof hangars communicating with aircraft storage orservice areas.b. At least 8 feet above the floor in public garages.Minimum clearances marked on theheater must be maintained from vehicles parkedbelow the heater.2(FOR CANADA ONLY)a. Installation of this appliance is to be in accordancewith latest edition of CAN 1-B149.1 (InstallationCode for Natural Gas Burning Appliances andEquipment), and/or CAN B149.2 (InstallationCode for Propane Gas Burning Appliances andEquipment).b. For installation in public garages or aircraft hangars,the minimum clearances from the bottom of theinfrared heater to the upper surface of the highestaircraft or vehicle shall be 50 percent greater thanthe certified minimum clearance, but the clearanceshall not be less than 8 feet.Although these heaters may be used in manyapplications other than space heating (e.g.,process heating), manufacturer will not recognizethe warranty for any use other than space heating.This heater is for Indoor Installation and CoveredPatio Installation only and can be used in eitherVented or Unvented mode. The term Unventedactually means Indirect Vented. While the productsof combustion are expelled into the building, nationalcodes require ventilation in the building to dilute theseproducts of combustion. This ventilation may beprovided by gravity or mechanical means.This heater is not an explosion proof heater. Wherethe possibility of exposure to volatile and low flashpoint materials exists, it could result in propertydamage or death. This heater must not be installedin a spray booth where the heater can operate duringthe spraying process. Consult your local fire marshalor insurance company.RSS Series Only: Since straight tube heatersare always hotter at the control end than at theflue terminal end, always observe the minimumrecommended mounting heights shown on thespecification sheets and in Section 3.0 of thismanual. Use U-tube configuration instead ofstraight tubes for spot or area heating (e.g.,where a single heater is utilized for spaceheating).Certain materials or objects,when stored under the heater, will be subjectedto radiant heat and could be seriously damaged.Observe the Minimum Clearances to Combustibleslisted in the manual and on the heater at all times.

STERLING “RSS” SERIESINFRARED RADIANT TUBE HEATER2) MINIMUM CLEARANCES TO COMBUSTIBLESMinimum clearances to combustibles shall be measured from the outer surfaces as shown inthe following diagram:ModelRSS/RSU 40RSS/RSU 50RSS/RSU 75RSS/RSU 100RSS/RSU 125RSS/RSU 150RSS/RSU 175RSS/RSU 200Sides22"22"22"28"28"34"38"42"MINIMUM CLEARANCES TO COMBUSTIBLESMounted 56"60"70"76"81"86"93"15"15"15"15"20"20"20"20"Angle Mounted at 45 45 Front45 2"* When used indirect vented, minimum clearance for CEILING must be: 12" for RSS/RSU 50-75 and 18" for RSS/RSU 100-200.If optional corner and u-bend reflectors are not used, the clearance must be 18".** Maximum clearance below reduces by 50% once you are 25ft. downstream from the control box.NOTE: The clearances specified above must be maintained to combustibles and other materials that may be damaged bytemperatures 90 F above ambient temperature. Clearances to combustibles are posted on the control box. In areas used forstorage of combustible materials where they may be stacked below the heater, NFPA54 requires that the installer must post signsthat will “specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles.”The manufacturer recommends posting these signs adjacent to the heater thermostat or other suitable location that will provideenhanced visibility.3

STERLING “RSS” SERIESINFRARED RADIANT TUBE HEATERSINGLE HEATER VENTING(VERTICAL THROUGH THE ROOF)1. When venting the heater to outside of buildingthrough a roof, use single-wall metal pipe. Thisis to be constructed of galvanized sheet metal orother approved noncombustible corrosion-resistantmaterial as allowed by state or local codes.5. All portions of the vent pipe shall be supported toprevent from sagging (6' spacing is recommended).2. A vent passing through a combustible roof shallextend through an approved clearance roof thimble.7. Minimum clearance for single-wall flue pipe tocombustible material shall be 6 inches. This maybe reduced when the combustible material isprotected as specified in the National Fuel GasCode or the authority having jurisdiction.Double-wall, Type B vent must be used for theportion of the vent system which passes throughthe roof. An approved vent cap (Leslie “VersaCap”Type B or equal) must be attached to end of theflue.3. The maximum equivalent length of vent pipe shouldbe carefully observed. A safety switch in the heateris designed to shut the heater off before excessiveflue restriction causes bad combustion. Refer to theVent Sizing Table for maximum vent lengths andvent pipe diameter.4. Joints between sections of piping shall be fastenedby sheet metal screws or other approved meansand should be sealed to prevent leakage of fluegas into building. Aluminum or Teflon tape suitablefor 550 F (3M Company tapes 433 or 363) orsilicone sealant is recommended.6. When the vent pipe passes through areas where theambient temperature is likely to induce condensationof the flue gases, the vent pipe should be insulatedand a condensation drain should be provided.8. Single-wall metal pipe shall not originate in anyunoccupied attic or concealed space and shallnot pass through any attic, inside wall or concealedspace, or through any floor. For the installation of asingle-wall metal pipe through an exteriorcombustible wall, refer to latest edition of theNational Fuel Gas Code or the authority havingjurisdiction.9. A venting system shall terminate at least 3 ft. aboveany forced air inlet located within 10 ft.19

STERLING “RSS” SERIESINFRARED RADIANT TUBE HEATERSINGLE HEATER VENTING(HORIZONTAL THROUGH SIDEWALL)When venting the heater horizontally through acombustible outside sidewall, the same requirementslisted previously for venting “Vertical Through TheRoof” apply except as follows:5. When venting through a sidewall, the horizontalvent pipe shall fall not less than 1/2 inch per20 feet from the start of the vent system to thevent terminal. All portions of the vent pipe shallbe supported to prevent sagging. (6' spacing isrecommended)1. A vent passing through a combustible wall mustpass through an approved clearance thimble (AirJet #4VT or Ameri-Vent #4EWT or other thimblesthat are listed by a nationally recognized testingagency.6. A minimum clearance of 6 inches must bemaintained between the outside wall and vent cap.2. An approved vent cap (Breidert-Type L or equal)must be attached to the end of the vent pipe.NOTE: To minimize problems associated withcondensation in long horizontal runs, vent pipecan be insulated.3. Use the following correction factors to obtain theequivalent length when elbows are used:c. Subtract 10 ft. for each elbow beyond 15 ft. fromthe heater.d. Subtract 15 ft. for each elbow within 15 ft. of theheater.4. Limit to (2) 90 elbows in the vent system.7. The horizontal venting system shall not terminate:a. 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 anybuilding. The bottom of the vent terminal shallbe located at least 7 ft. (2.1m) above grade orabove snow accumulation level as determinedby local codes.b. Less than 3 ft. (0.9m) from a combustion air inlet.c. Less than 3 ft. (0.9m) from any other buildingopening or any gas service regulator.d. Less than 7 ft. (2.1m) above public walkways.e. Directly
