COMPLETE THE VENTING
Refer to Fig. 18.
Install oval to round adapter. Complete the piping extending it
through the roof. Use 4" round, double wall (Type B) vent pipe,
roof flashing, storm collar, and vent top as shown. The vent cap
must be at least 2 feet higher than any point that is within 10 feet
horizontally of the vent cap. There must be at least 1 inch
clearance between the vent pipe and any combustible material.
IMPORTANT
Area above header within the stud space MUST be kept clear of
any attic insulation to allow the free circulation of air around oval
vent piping.
Mounting Your Furnace

gas supply fittings, it may be necessary to remove the burner and
control assembly as follows:
Remove burner compartment door by pulling door top out and up.

burner control compartment. Remove two (3) screws and shield
and set aside. Refer to Page 31, item #3.
