Page 3: Safety
1.0) SAFETY This heater is a self-contained infrared radiant tube heater. Safety information required during installation and operation of this heater is provided in this manual and the labels on the product. The installation, service and maintenance of this heater must be performed by a contractor qualified in the installation and service of gas fired heating equipment. - Page 4 Although these heaters may be used in many applications other than space heating (e.g., process heating), Space-Ray will not recognize the warranty for any use other than space heating. This heater is for Indoor Installation and Covered Patio Installation only and can be used in either Vented or Unvented mode.
-
Page 5: Minimum Clearances To Combustibles
NFPA54 requires that the installer must post signs that will “specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles.” Space-Ray recommends posting these signs adjacent to the heater thermostat or other suitable location that will provide enhanced visibility. -

Page 18: Typical Suspension Methods
6. Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent structure with adequate load capacity. Space-Ray recommends that the body sections be suspended using chains with turnbuckles. This will allow slight adjustments after assembly and heater expansion/ contraction during operation. -
Page 19: Assembly Of Tube Sections
10.0) ASSEMBLY OF TUBE SECTIONS During field assembly of the heater body sections, the recommended procedure is as follows: 1. Before hanging heater sections, first determine the actual layout of the system (see Sections 7.0) & 8.0) for details). Consideration must also be taken for flue pipe, fresh air ducting, gas piping, clearances to combustibles, etc. -
Page 20: Assembly Of Extension Section
10.1) ASSEMBLY OF EXTENSION SECTION See typical assembly overview (Section 8.0) for typical complete assembly. Assemble additional extension sections as required for all systems. (See Sections 7.0), and 8.0) for typical layout details.) Join the tube sections together and secure with tube couplings as described below: The following coupling tightening instructions MUST be followed properly to ensure the integrity of the tube connections. -
Page 21: Inserting Turbulators
4. Slide the next tube into the coupling. 5. Make sure both tube ends are butted together. 6. Finish tightening both bolts to 40-60 ft.lbs. torque to ensure a complete seal. 7. Use the two Self-drilling screws through the pre-punched holes to secure the tubes in the coupling. 8. -

Slide the reflectors on the tube support/hanger brackets and through the wire hangers. 2. The tube at the coupling joints must be covered. Slide the reflectors together and provide an overlap of two (2”) inches for the first reflector overlap after the control unit. -
Page 23: Adding Optional 90º Elbow (Pts Only)
11.0) ADDING OPTIONAL 90º ELBOW (PTS ONLY) 1. The optional 90º elbow must be located a minimum of 10 ft. after the burner box. 2. Hang the body sections in a 90º ("L") shaped pattern. Allow spacing for the elbow. The distance from one end of the elbow to the centerline of the opposite leg is 13"... -
Page 24: Adding 180º U-Bend (Ptu Only)
11.2) ADDING 180º U-BEND (PTU ONLY) 1. Hang body sections parallel with each other. The centerline distance from tube at each body section should be 18” as shown. 2. Join tube ends of body sections and the U-Bend together and secure with tube couplings as described in Section 10.1). -
Page 25: Attaching Burner Box Assembly
12.0) ATTACHING BURNER BOX ASSEMBLY 1. Attach the burner box and gasket to end of tube flange and secure with 1/4-20 locknuts. 2. Assemble the optional end reflector flush with the end of the main body reflector. Secure by sliding speed clips onto the reflector edges. -
Page 26: Connecting The Tiss System
12.1) CONNECTING THE TISS SYSTEM Description: The TISS (Tube Integrity Safety System) is designed to shut the main burner off in the event that a burnout occurs in the first 10ft. section of firing tube. Note: When replacing the firing tube a new TISS wire assembly PN 44176010 (spring and spring retainer clamp not included) must also be installed. - Page 27 3. Hold the spring retainer clamp and pull the TISS wire assembly to end of reflector at overlap joint. Slide spring retainer clamp over end of reflector as shown. Step 3 4. After attachment of the TISS, check to make sure that there is sufficient tension on the wire. Follow the diagram below to increase or decrease the tension as necessary.
- Page 28 ANGLE MOUNTED HEATERS ONLY 5. If heaters are to be angle mounted, the TISS wire holder clamp must first be re-positioned as shown using the bottom hole pattern of the clamp. Follow procedures described earlier for all other adjustments. Step 5 Form #43343530 Mar 09 -27-...
