11.
Slide reflector panels and space between burner box and U-bend (U-model heaters only) as indicated on
heater dimension drawings. Reflectors must overlap approximately as shown on the dimension drawings.
12.
Secure reflectors to tube support/hanger brackets using the screws and clamps (supplied in fastening kits).
Note: Refer to details A or B of each assembly overview drawing for the required open or closed positions of
the clamps. These positions enable reflectors to side or remain stationary during operation of heater.
13.
Place end reflector panels flush to each end of main heater reflector panels and secure by spacing two (2) U-
type speed clips (supplied in fastening kits) evenly on edges of each reflector flange.
14.
Make all final gas and electric connections as outlined later in the instructions.

TUBE COUPLING DETAILS
Join the tube sections together and secure with tube couplings as described below. Note: The heater tube section
should be provided a slope of 0.25 degree up to the fan.
The following coupling tightening instructions MUST be
followed properly to ensure the integrity of the tube
connections. Two #10 self-drilling screws MUST be installed
at every coupling as shown in the instructions below. Failure
to do so may result in serious injury or property damage.
a.
Place the compression coupling over the end of the tube.
b.
Use the small hole at the centerline of the coupling to check that the coupling is inserted correctly.
c.
Partially tighten the bolt nearest the end of the tube (approximately half closed).
