INSTALL SURFACE VENT (SURFACE MOUNT)
NOTE
For surface mounting, it will be helpful to complete the gas
piping supply to the furnace before installing the vent pipe.
See section GAS SUPPLY & PIPING, page 17.
Carefully move the furnace into position under the ceiling
cutout.
Insert first lengths of oval, double wall vent pipe up through
the ceiling cutout. Lower vent pipe to the hold-down plate.
Push the vent pipe into the hold-down plate until it is
completely seated. (Hold-down cleats will engage the groove
in the vent pipe.)
