ATTACHING CONTROL BOX ASSEMBLY

1. Attach the control box and gasket to end of tube flange and secure with 1/4-20 locknuts. NOTE: The control box must
be mounted to a 10 ft. aluminized steel body section for 40-200 MBtu/hr models, or to a 10 ft. Alumi-Therm steel body
section for 225-250 MBtu/hr models, regardless of configuration used. Failure to attach the control box to the flange
end as indicated above will void the manufacturer's warranty.
2. A 3/8" connector is located on the left side of the control cabinet to provide strain relief for field wiring to the draft
inducer junction box (refer to Section 18 on Electrical Connections and Connection Wiring Diagram for wiring between
the control box and the draft inducer.)
3. Assemble the end reflector flush with the end of the main body reflector. Secure by sliding speed clips onto the reflector
edges. Evenly space the speed clips on the sides (one each side) and top (two required) of the reflectors to provide a
snug fit. Leave a 3" space between the end reflector and the control box assembly.
4. The control box must be mounted with the perforated fresh air plate on top, facing the ceiling.
