Reflectors and reflector accessories direct infrared energy to the floor level. The reflector assembly
depends on the heater configuration, proximity to combustibles and space surrounding the heater.
Before you begin assembly, determine if the use of reflector accessories are necessary (P. 29).
To install the reflectors (Figure 3.14):
1 Attach the reflector center supports onto radiant tubes at the halfway point between hangers.
2 Slide each reflector section through the hangers and adjust the reflector tension spring into the
V-groove on the top of the reflector. The reflectors should overlap approximately 4 inches for support.
3 To prevent the reflectors from shifting during heater operation, secure reflector sections together using
sheet metal screws (field supplied). Allow for unsecured expansion joints between every second and
third reflector section following burners.
NOTE: When securing joints on reflectors which are rotated
on an angle from horizontal, secure joint only on top side of reflector to allow for sufficient heater
expansion and contraction.
4 Install reflector elbows, crosses, tees, etc. atop the applicable fittings if the system uses them.
5 Attach reflector end caps, with polished finish inward, to each end of the reflector run and to any
exposed elbows, crosses, tees, etc. Secure with reflector end clips provided or sheet metal screws
(field supplied).
