ADDING REFLECTORS
1. 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

approximately one (1”) inch. This will allow for the natural expansion and contraction of the heater when in
operation. Note: The heaters can expand and
