The clearance tothe bottom of the heater shall be measured from the upper surface of either the fuel storagecompartment or the engine enclosure; whichever is higher from the floor.A minimum clearance of 8 ft (2.4m) must be maintained from the bottom of the heater to thefloor in other sections of the aircraft hangar, such as offices and shops, which communicate withareas for servicing or storage. For proper mounting clearances, refer to the clearances tocombustibles in these installation instructions.Heaters must be located where they are protected from damage to aircraft and other objects, suchas cranes and movable scaffolding.Heaters must be located so as to be accessible for servicing and adjustment.INSTALLATION IN COMMERCIAL GARAGES AND PARKINGSTRUCTURESLow intensity heaters are suitable for use in commercial garages when installed in accordancewith the latest edition of the Standard for Parking Structures, ANSI/NFPA 88A, or the Standardfor Repair Garages ANSI/NFPA No. 88B, or the Canadian Natural Gas and Propane InstallationCode, B149.1WARNINGINSTALLATIONS OTHER THAN SPACE HEATING11
Use for process or other applications that are not space heating will void the products warranty.Process application requires field inspection and/or certification by local authorities havingjurisdiction.IMPORTANTSingle or multiple heater placement must be such that continuous operation of heater(s) will notcause combustible material or materials in storage to reach a temperature in excess of ambienttemperature plus 90 degrees Fahrenheit (50 degrees Celsius).It is the installer’s responsibility to ensure that building materials with a low heat tolerance,which may degrade at lower temperatures, are protected to prevent degradation. Refer toClearance to Combustibles information in these installation instructions.GENERAL INSTALLATION PROCEDUREPRE-INSTALLATION SURVEYIt is recommended that a full heating design, including a heat loss calculation be conducted.Heater sizing and placement must consider available mounting height, sources of heat loss, andclearances to combustibles with respect to stored material, moveable objects (cranes, vehicles,lifts, overhead doors, etc) sprinkler systems, and other obstructions on the site. Considerationmust also be given to vent / duct placement and the allowable combined lengths of vent and duct.1. Carefully survey the area to be heated and place the burner and combustion chamber inthe coldest area if possible.2. The heater shall be hung in such a fashion so as to conform with the clearances tocombustibles described on the name plate.3. Clearances to combustibles must be maintained from vehicles parked below.4. Adequate clearances must be maintained for installation in public garages and airplanehangar.5. It should be located with respect to building construction and equipment, so as to providesufficient clearances and accessibility for servicing.6. The installation must comply with local codes and CAN/CGA B-149 in Canada or theNational Fuel Gas codes ANSI Z 223.1 in the United States.ELECTRICAL120V, 60 HZ, 3 AMPS STARTING, 1 AMP RUNNINGIgnition System:120 Volt / Hot surface igniterThermostat control:Heaters are designed for compatibility with either 120 Volt thermostat controllers or 24 Voltthermostat controllers. For use with 120 Volt controllers, the heater must be plugged into a“switched” 120 Volt duplex receptacle, where the receptacle is switched by the thermostatcontroller. Heating zones may be established where one 120 Volt thermostat, controls more thanone heater, provided the total heater electrical load does not exceed the maximum allowableamperage on the circuit.12
For 24 volt thermostat control plug the heater into a 120 Volt duplex receptacle. Remove thejumper wire on the control box marked “24 Volt thermostat” and connect the thermostat wire tothe terminals. Ensure that if the thermostat has a heat anticipator, that the heat anticipator is setat maximum. When using a 24 Volt thermostat, only one heater may be controlled by onethermostat.1. Electrical installation must be grounded in accordance with CSA standard C22.1 part 1 inCanada or The National Electrical code ANSI NFPA 70 (latest edition) in the UnitedStates.2. Polarity of line voltage and neutral wires must be maintained.3. The total load of all heaters in a circuit must be considered not to overload the circuit.SUSPENDING THE SYSTEMInadequate or improper suspension of the tube heater can result in collapse of the system, propertydamage, and personal injury or death. It is the installer’s responsibility to ensure that the hardware andstructural supports from which the heater is suspended are sound and of adequate strength to support theweight and expansion forces of the heater.Consider that the heater will expand in length as much as ½ inch (12.7) or more for every 10 ft(3 m) of system length. Typically, the greater the firing rate, the greater the expansion.Survey the available structural supports, considering the system configuration and heat requirements ofthe area to establish the optimum heater location. Locating a heater directly under joists or beams, orinstalling supplemental steel support rail or angle iron can substantially reduce labour and materials.Hardware with a minimum 60 lbs (27 kg) workload must be used at each heater suspension point.Connect the structure using typical hardware as illustrated below or by other mechanically sound means.13
REFLECTOR EXTENSIONSReflector extensions may be installed on one side or both sides of the reflector. Reflectorextensions are 10 ft long x 9”. Drill 3 holes and insert S hooks.GAS PIPING1. All gas piping and connections shall be made in accordance with local codes andCAN/CGA B-149 or ANSI standard Z223.1.2. Connect the burner to gas supply with flexible gas connector.3. A drip leg must be installed in the gas line at the heater inlet connection tee followed by apipe drop to the heater. Failure to provide a drip leg could result in condensation andforeign matter passing into the gas valve. Failure to install a drip leg in the gas line cancause property damage, injury or death and will void the heater warranty.14
CAUTION: Correct inlet pressure is vital to efficient operation of heaters. Refer to the ratingplate and, if necessary, consult Gas Company.WARNINGNever use a match or other flame to test for gas leaks. Use soap and water solution to checkfor leaks to all connections and joints and if bubbles appear, leaks have been detected andmust be corrected. Never operate the heater with leaking connections. The supply system15
should be checked first with heater turned off followed by another check with the heater on.The supply gas pressure must be checked with all heaters in operation.GAS SUPPLY, HEATER EXPANSION, AND FLEXIBLE GASCONNECTIONThe gas supply must be installed to the heater using:In USA an approved Stainless Steel Flexible Gas Connector certified for use on an infraredradiant tube heater (ANSI Z21.24 CSA 6.10)In Canada an approved Type 1 Hose Gas Connector (CAN/CGA 8.1)The heater must be isolated from the gas supply piping system by closing its individualmanual shut off valve (field supplied) during any pressure testing of the gas supply pipingsystem.Compensation for normal gas supply pipe expansion, and radiant tube heater expansion mustbe provided. All piping must conform to local codes.Provide a 1/8 in (3.2mm) NPT plugged tapping, accessible for test gauge connection,immediately upstream of the gas supply connection to the heater.Test for leaks. All gas piping and connections must be tested for leaks after the installation iscompleted.Apply soapsuds solution to all connections and joints and if bubbles appear, leaks have beendetected and must be corrected. Do not use a match or open flame of any kind to test forleaks. Never operate the heater with leaking connections.The supply systems should be checked first with the heater turned off followed by anothercheck with the heater turned on. The supply gas pressure must be checked with all heaters inoperation.WARNINGThis heater will expand in length as it heats up. It is a normal condition that during heat-upand cool-down a tube heater will expand and contract. Allowances for heater expansion mustbe made in the gas connection, venting and combustion air ducting. Improper installation,alteration, or adjustment can result in property damage, injury or death.16
The BTU input and the tube length determine the overall expansion that occurs. A typicalinfrared tube installation will expand toward both the burner and the vent end.To allow heater expansion the gas supply must be installed using:In the USA: a stainless steel flexible gas connector certified for use on an infrared radianttube heater (ANSI Z21.24 CSA 6.10)In Canada: a Type 1 hose connector (CAN/CGA 8.1). Also the flue vent, and combustion airintake (if used) must be installed in such a manner that the normal expansion of the heaterwill be accommodated.VENTING OPTIONS17
