ROOF SUPPORT PACKAGE
(PART NO. RSP)
The Roof Support Package is an ideal assembly for freestanding fireplaces
and open cathedral ceiling installations. It fits all roof pitches and requires
only simple framing. The package contains one 18" length of pipe with
thimble plates, two roof brackets and necessary hardware. Maximum
length of chimney which can be suspended below is 20 feet. Maximum
total chimney length is 30 feet.

Locking Bands (LB) or
Three Screws Per Joint.
Follow these simple steps for a roof supported chimney installation:
1. Cut an opening in the roof and frame all around the opening to distribute
weight load (Fig. 1). Be sure to allow for a 2" minimum clearance
(Figs. 1 AND 2).
2. Center assembly in the opening. Adjust plates to the roof pitch and
tighten nuts (Fig. 2).

3. Install six screws per roof plate with the innermost screws going into
rafters or headers (Fig. 1).
6. Finish roofing around chimney, covering the side and upper areas of
flashing flange. Be sure lower unnailed portion of flange covers roofing.
4. Twist lock (connect) additional lengths of chimney pipe to top of assembly
as necessary to obtain the required minimum chimney height above roof.
Chimney outlet should be at least 2 feet higher than any adjacent structure
within 10 feet).
7. Place Storm Collar (SC) down over chimney until it touches flashing
and fasten. Apply silicone sealant between pipe and collar.
5. Install a Flashing, suitable for the roof pitch, by sliding it down over the
top chimney section and nailing to roof through sides and top flanges. Do
not nail the lower portion of the flashing flange. Use nails with a neoprene
washer or cover nails with mastic. (See Installation Sheet S-3.)
