Roberts Gorden CTHN-175 Reflector Support Package, Unitary Linear & U-TUBE Heater Installation

SECTION 8: UNITARY LINEAR & U-TUBE HEATER INSTALLATION

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.

1.The first reflector after the burner must be affixed in the middle of the reflector with a reflector support and tight screws.

Overlap must be a	6"
minimum of 6" (16 cm).	(16 cm)

2.The overlap at the first and second reflector is a slip overlap. Thereafter, every third reflector joint is a slip overlap. A slip overlap is achieved by either:

a.) both reflectors lay inside a hanger. (No reflector support needed.)

b.) using a reflector support with loose screws at the reflector overlap.

3.The remaining reflector overlaps require a non-slip overlap connection. To affix the reflectors together in a non-slip overlap either:

a.) use reflector support and tight screws.

b.) if both reflectors lay inside a hanger, u-clips or sheet metal screws may be used.

This section of three reflectors joined together must be affixed to the tube with at least one reflector support with tight screws.
