Assembled Replacement Downturn Plenum Cabinet - If a downturn plenum cabinet needs to be added to the system at the
installation site, order the appropriate P/N (above) for a factory-assembled cabinet. Since this cabinet is not factory-built on the
system curb cap, a platform or legs must be field fabricated to support the downturn plenum cabinet. Do not support the downturn
plenum cabinet with the ductwork. The ductwork connection and roof opening must be flashed and/or sealed to prevent water from
entering the ductwork or the building.
Optional Downturn Plenum and Discharge Damper - Applies to Model Series RGB/RPB, Model
Series RGBL/RPBL, and Blower Cabinet Model RBL

Instructions for Attaching Replacement Cabinet
1) If the heater is operating, turn off the gas and the electric.
2) Position the "open" side of the cabinet against the heater discharge.
The top and side posts of the cabinet will "overlap" the heater.
Fasten on both sides and across the top with field-supplied, weather-
resistant sheet metal screws.
3) Provide field-fabricated, weather-resistant support for the cabinet.
4) Attach ductwork to the flange on the cabinet. Flash and/or seal the
ductwork and the roof opening to prevent water from entering the
building or the ductwork.
5) Turn on the electric and the gas. Follow the instructions on the
lighting instruction plate. Check the heater for proper operation.
