Vertical installation
Two (2) elbows
Four (4) elbows
After reaching the location requiring the elbow, proceed as follows:
1. To insure a good draft, it is recommended, but non‐mandatory, to have a length of 18 inches (457 mm)
from the top of the unit to the first offset. Install the first elbow; turn it in the required direction. Secure
it to the chimney according to the chimney manufacturer's instructions. In many cases, it is
recommended to secure connections with three (3) ½" (12 mm) metal screws.
2. Install the necessary chimney lengths to achieve the required offset. Lock the chimney lengths together
according to the chimney manufacturer's instructions. In many cases, it is recommended to use three
(3) ½" (12 mm) metal screws. If the offset length is made of two (2) chimney lengths or more, many
chimney manufacturers 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 (see Section
4.4.1: Examples of Typical Chimney Installation).
3. Use another elbow to turn the chimney vertically. Secure the elbow.
4. Use a plumb bob to line up the centre of the hole. Cut a hole for the chimney in the ceiling/floor. Frame
this hole as described previously.
5. From below, install a firestop supplied by the chimney manufacturer.
6. A support must be used on the first 15' section (4.6 m).
7. Continue with the regular installation.
4.6 Angled Wall Radiation Shield
When passing through a combustible wall with the chimney at a 30 or 45 angle (30 or 45 in Canada and
30 only in the USA), an angled firestop or wall radiation shield provided by the chimney manufacturer must
be installed. Only one is required. Follow the chimney manufacturer's installation instructions.
In cold climate locations, it is recommended that you use the insulated wall radiation shield since it will
maintain the home's thermal barrier.
