Installing The Roof Jack

1.Apply caulking compound on underside of roof

flashing to form a continuous strip at least 3/8” wide around the underside of the perimeter of the fl ashing. See Figures 20 or 21.

2.Connect Roof Jack Assembly to the furnace. Insert telescoping Roof Jack Assembly through the opening cut on the roof.

3.Connect fl ue pipe to fl ue collar of furnace. See Figure 22.

4.Connect combustion air pipe to furnace collar with sheet metal screw (See Figure 22).

NOTE: It is recommended that the connection of the combustion air pipe to the furnace be made before the fl ashing is secured to the roof to maintain alignment of roof jack and furnace connections.

NOTE: For replacement furnaces, be sure the inner fl ue pipe connects over the furnace vent collar. DO NOT use a smaller diameter inner flue pipe which could slide inside the furnace vent collar and restrict the flow of furnace flue products.

5.Attach Roof Flashing. If necessary, shift roof

flashing slightly in the roof opening so that assembly is in alignment with furnace.

NOTE: If fl ashing is mounted on 12 degree angle, it may be necessary to adjust the angle to match the roof pitch;(1/12 - 4/12 maximum).

6.Press down fi rmly on roof fl ashing (over caulking) to make the seal with roof water tight.

7.Secure fl ashing with appropriate fasteners.

NOTE:For added protection against leaks, coat the fl ashing plate and fasteners with approved roofi ng compound.
