CTHN-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL 22 Step 8.9 Reflector Installation Description Part Number Tube/Reflector Hanger 03090100 Burner Tube 03051XXX Reflector 02750303 NOTE: All radiant tube surfaces must be covered by a reflector, except for a u-tube. Manifold tube may or may not be covered. SECTION 8: UNITARY LINEAR & U-TUBE HEATER INSTALLATION 23 Step 8.9.1 Reflector, U-clip and Reflector Support Installation The pictorial drawings of the heater construction in Section 8 are schematic only and provide a general guideline of where hangers, reflector supports and u-clips are to be installed. To ensure proper expansion and contraction movement of the reflectors, a combination of u-clips and reflector supports are used. The positioning of reflector supports and u-clips depend on the individual installation. Use either pop rivets or sheet metal screws instead of u-clips when installing end caps and joint pieces in areas where impact and high wind may be a factor. The following rules must be observed. 6 " " 6 # "M " # K 0 " # .
