Assembly prior to hanging: With this method, the use of two saw horses or a raised table or bench
surface is beneficial (the emitter assembly and reflector box may also be used).
1 Lay the emitter assembly (TP-6082) across the horses or bench with the exchanger connection
hanging bracket extended out over the edge (See Detail ‘A’) NOTE: Use of the foam shipping blocks
will help protect the emitter coating and reflectors.
2 Install the tube flange gaskets (TP-6021B) onto the corresponding studs on the burner control box.
3 Align the nine (9) burner control box studs with the eight (8) holes located on the emitter plates and
the one (1) hole on the exchanger connection hanging bracket.
4 Install nine (9) 5/16 - 18 keps nuts provided, tightening evenly and torque to 20 ft-lb.
Reflector Sub-Assembly
1 On a flat surface, lay out two reflectors (TP-6088) parallel to each other.
2 Place U-end reflector end cap (TP-6084A) at one end and burner reflector end cap (TP-6085A) at the
opposite end with the “over/under tabs” facing the reflector.
3 Move the reflector end caps into the reflector ends while aligning the “over tabs” (larger tabs with
holes) over the top of the reflector and the “under tabs” (smaller tabs with no holes) under the reflector
(see Detail B). This can be achieved by squeezing the reflector slightly to fit into the end cap.
4 Properly secure reflector end caps to reflectors using #8-1/2” screws (TP-62) through the hole into the
reflector, being careful not to strip.
5 Repeat process with the remaining two reflectors.
