2. Make a 5 1/4" hole in the outside wall of the house.
Mount the register in the hole from the outside with the
inlet facing down.
3. Place the insulated flexible duct over the register tube
and outside air connector sleeve. At both ends, care-
fully pull back the insulation and plastic cover, exposing
the flexible duct. Then at each end, attach the duct with
metal screws to the inlet and tube. Carefully push the
insulation and cover back over the duct. Tape the plas-
tic cover in place with the 2" aluminum duct.
CAUTION:
When running duct around corners, be sure
to prevent crimping that would restrict the combustion
airflow.
Use a 5" diameter insulated duct rated at over 200° F.

Our testing has shown that as long as the 5" diameter
insulated duct is utilized properly, there is no restriction
on the length of the run. It is recommended that the
duct does not exceed 12 ft. vertical height rise above
the base of the unit. The air inlet should never be less
than 5 ft. below the top of the chimney flue.
Outside air door
The Opel 2000 is designed to use outside air instead of
inside air for combustion but you may choose to use
inside air for combustion air.To do so, open the sliding
door on the bottom inside right of the fireplace (behind
the bottom louver. Note that the fireplace uses outside
air when the handle is closer to the back of the fireplace
and inside air when its closer to the front. We
recommend the use outside air for combustion.
