4. Assemble the chimney sections so the finished length is resting on the manufacturer's anchor plate and
protruding through the roof. Avoid having joints between the ceiling and the roof. It is required that the
chimney connections be secured with three (3) #8x½"(12 mm) stainless screws.
5. As per the vent manufacturers instructions, Install the Roof Radiation Shield, Flashing and Storm Collar.
Be sure to maintain the vapour barrier at this point. (Seal securely.)
6. Install any exterior venting - If the chimney extends more than 5'(1.5m) above the point of contact with the
roof, then it must be secured using roof braces
7. Securely attach the rain cap and check the flashing for leaks.
Offset Chimney:
The chimney for the FP25 can be installed with a maximum of four
45° elbows(in Canada) or four 30° elbows(in U.S.A.) as shown in
Figure 11.
Follow the chimney manufacturer's guidelines for supporting the
offsets. Reminder - The chimney must be supported after the first
20'(6.1m) in length.
1. NOTE: Install the vertical chimney section(s) then the first elbow
and turn it in the required direction.
2. Install the necessary chimney lengths to achieve the required
offset. Lock the chimney lengths together according to the
chimney manufacturer’s instructions. If the offset length is made
of two (2) chimney lengths or more, many chimney manufactur-
ers may require that you use an offset or roof support halfway
up the offset. If penetrating a wall, install a wall radiation shield
supplied by the chimney manufacturer and install according to
the manufacturer's instructions.
3. Use another elbow to turn the chimney vertically and secure the
elbow.
4. Use a plumb bob to line up the centre of the hole with the center of the flue collar on the fireplace. Cut a
hole for the chimney in the ceiling/floor. Frame the hole as described in Figure 10 on page 19.
5. Install all firestops following the chimney manufacturer's directions.
