requires field assembly. To adapt the heater for power venting, the following
pieces are used:

Flue Collar Support provided with the heater
•
Flue Adapter Assembly provided in the optional power vent kit with the
restrictor attached in Step 2.(a) (See
FIGURE 4B.)
•
Flat Cover provided with the heater

will not be used.
Refer to the instructions in the heater installation manual or Instruction

with the restrictor attached.
