WARNING Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read and understand this installation and operation manual thoroughly prior to assembly, installation, operation or service to this appliance. This heater must be installed and serviced only by a trained gas service technician. Do not store or use gasoline or other flammable vapours and liquids in the vicinity of this or any other gas fired appliance.
WARNING Heater Expansion It is a normal condition that during heat-up and cool-down a tube heater will expand and contract. Allowances for heater expansion must be made in the gas connection, venting and combustion air ducting. Improper installation, alteration, or adjustment can result in property damage, injury or death. Refer to Section 12 WARNING Gas Connection Improper installation, connection, or adjustment can result in property damage, toxic gases, asphyxiation, injury or death.
WARNING Tube “GLOW” It is a normal condition that the combustion tube (1st tube) can appear to “glow red”. For inputs up to 205,000 Btuh, the top surface of the tube can appear red where heat is trapped between the reflector and the tube. The stainless steel tube used for inputs 225,000 and greater can appear to entirely glow red.

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. Examples of low heat tolerance materials include vinyl siding, fabrics, some plastics, filmy materials, etc. VENT END CLEARANCE: Clearances from the vent pipe are determined by local or national installation codes, but must not be less than 6 inches (15 cm).
1. LABOR REQUIRMENTS Two workers are required to safely install this equipment. Wear gloves and other required safety protection. 2. INSTALLATION IN COMMERCIAL AIRCRAFT HANGARS Low intensity radiant tube heaters are suitable for use in aircraft hangars when installed in accordance with the latest edition of the Standard for Aircraft Hangars, ANSI/NFPA No 409 in the USA. A.

7. SYSTEMS INCORPORATING 90° ELBOWS AND 180° ELBOWS The radiant tube heater can be installed in configurations as illustrated in Figure 4 with a maximum of two 90° elbows per heater. Each elbow in the system is equivalent to 5 lineal feet that is part of the maximum total system length. (See Section 11 : Flue venting) A 90° elbow kit (906000123) includes one 90° elbow, one tube coupler, one elbow reflector, and two web brackets. For a 180° elbow, order 2 x 90° kits that assemble to create a 180°.
INSTALLATION INSTRUTIONS FOR 90° ELBOW KIT When installing systems that incorporate a 90° elbow, assembly of the system is facilitated by first locating and installing the elbow assembly, then install the remainder of the tube/ reflector system working away from the elbow. Add the coupler to the 90° elbow over the swaged end of the elbow. Slacken the coupler bolts. Slide the coupler over the elbow from the swaged end. Add the plate hanger to the system at the same end where the coupling is located.
8. SUSPENDING THE SYSTEM - GENERAL Inadequate or improper suspension of the tube heater can result in collapse of the system, property damage, and personal injury or death. It is the installer’s responsibility to ensure that the hardware and structural supports from which the heater is suspended are sound and of adequate strength to support the weight and expansion forces of the heater. Consider that the heater will expand in length as much as 1/2 inch (12.
9 INSTALLATION OF HANGERS, TUBES AND BURNER IMPORTANT SPECIAL NOTES: READ FIRST 1. Inputs 225 & 250 MBH: Special Tube Connection - Refer to Section 9.2, Fig 11 These input rates have an unpainted stainless steel first tube and second tube, and an unpainted aluminized steel tube as the third tube; all subsequent tubes are hot rolled steel. The first tube (stainless steel ) will “glow red” while heater is in operation - THIS IS A NORMAL CONDITION 3.
9.1 TUBE AND BURNER INSTALLATION Refer to the Single-Stage , Two-Stage Model, or Modulating Supplementary Manual for turbulator locations and tube kit assemblies for the various model input rates. 1) At each hanger use chain, cable, and/or other hardware rated for minimum 100 lb [45.
9) Subsequent lengths of tube can then be installed, by inserting the swaged portion inside the next tube and locking the joint using the Torctite coupler. SEE FIGURE 9. NOTE: For the 3rd and following tubes in the system: DO NOT install the welded seam facing downward along the length of the system after the first two tubes. Welded seams should randomly face toward one side or the other (3 or 9 o’clock), 90° up from bottom (6 o’clock).

Tube Coupler NOTE: Coupler can be used only once. Replace any coupler that has been loosened or removed. 4. Center coupler over tube joint 5. Tighten coupler bolts to 40 lb-ft. 1 1 3 FIGURE 10: HANGER / REFLECTOR ORIENTATION HORIZONTAL TO 45 0 TO ACHIEVE AN ANGLE LESS THAN 45° USE CHAIN TO BOTH EYES ON HANGER .
9.2 SPECIAL TUBE COUPLING: 225,000 to 250,000 Btuh NOTE: The joint of 1ST & 2ND tubes (225,000 - 250,000) experience strong forces of expansion. Follow instructions below for special coupling of the first few tubes in the system. SPECIAL COUPLING: INSTALLATION 1. Note the 2 holes opposite each other at the swaged end of the first and second tubes (225,000 250,000) 2.
10. SEISMIC RESTRAINT GUIDELINES - LATERAL AND LONGITUDINAL Tube must be allowed to expand and contract within the restrained hanger system. In areas prone to earthquake, or as specified on a project, install lateral and longitudinal seismic restraints as indicated in Figure 12. If the heater location can be impacted by wind (outdoors, aircraft hangars, etc) refer to High Wind Restraint Section 9.5, Figure 13. These restraint systems indicate typical suspension of and attachment to the heater.
11. REFLECTOR INSTALLATION NOTE: Ensure that you are installing a single reflector - reflectors can ‘stick together’ in packaging - take care to separate them individually. After burner and tubes have been installed, slide the reflectors one at a time into the wire hangers. As each successive reflector is installed on an in-line installation, the ends of the reflectors will overlap by approximately 4 inches [100mm] to provide continuous coverage over the entire tube system.
12. GAS SUPPLY - HEATER EXPANSION - FLEXIBLE GAS CONNECTION The gas supply must be installed to the heater using: • USA: an approved Stainless Steel Flexible Gas Connector certified for use on an infrared radiant tube heater (ANSI Z21.24 CSA 6.10); • The heater must be isolated from the gas supply piping system by closing its individual manual shut off valve (field supplied) during any pressure testing of the gas supply piping system.
WARNING HEATER EXPANSION THIS HEATER WILL EXPAND IN LENGTH AS IT HEATS UP. It is a normal condition that during heat-up and cool-down a tube heater will expand and contract. Some expansion is toward the vent end, and some expansion is at the burner end. Allowances for heater expansion must be made in the gas connection, venting and combustion air ducting. Improper installation, alteration, or adjustment can result in property damage, injury or death.
FIGURE 18 ORIENTATION OF FLEXIBLE GAS CONNECTOR The flexible gas connector MUST be installed in the orientation shown below as required by national installation codes and by the certification standard of this heater. This orientation protects the flexible gas connector from damage due to movement during heater expansion. It is the responsibility of the installer to ensure correct installation of the flexible gas supply.
13. ELECTRICAL AND THERMOSTAT WIRING (WIRING DIAGRAMS: SEE SUPPLEMENTARY MANUAL) NOTICE The heater must be electrically grounded in accordance with the National Electrical Code. ANSI / NFPA 70. Appliance and control wiring must be in accordance with all applicable local codes. The total load of all heaters must be considered in determining the required contact rating of the controlling thermostat or switch. Each tube heater requires 120V, 60 HZ electrical power sized for 145VA.

Options For Thermostat Control: NOTE: Fenwal DSI has an onboard relay switch to control the blower motor (120 Vac) and allows for heater control with either 24V or 120V thermostat. The Fenwal DSI has a post-purge feature. A Thermostat MUST be installed in the heater’s thermostat circuit to enable the post-purge feature of the ignition control. TruTemp Thermostat (24Vac - 3-Wire) True comfort control for radiant heating systems senses and averages ambient and radiant temperatures.
