Horizontal venting with three 90º elbows.
Note: for longer pipe runs, the total minimum vertical length is 3962.4mm and the total
maximum horizontal length is 3048mm.
General information:
1) Set the unit in its desired location. Check to determine if wall studs or roof rafters
are in the way when the venting system is attached. If this is the case, you may want
to adjust the location of the unit.
2) Direct Vent pipe and fittings are designed with crimped connections to connect
the venting system to the appliance flue outlet.
3) Put a bead of silicone inside the outer section of the adapter and a bead of Mill
Pac on the inner collar. Slip the adapter over the existing inner and outer flue collar
and fasten to the outer collar only with the 3 self tapping screws (drilling pilot holes
will make this easier). Level the fireplace and fasten it to the framing using nails or
screws through the nailing strips.
4) Assemble the desired combination of pipe and elbows to the appliance adaptor.
Note: Apply sealant "Mill-Pac" to inner pipe and high temperature silicone
sealant to outer pipe on every crimped joint.
