INSTALLATION INSTRUCTIONS:

Sonnet may be installed and vented into
any solid fuel fireplace that has been installed in accordance with the National, Provincial/State and
local building codes and has been constructed of non-combustible materials. Also refer to the

sections.
Refer to Figure 43 throughout installation.
2. Stretch both the Ø3” (76mm) flex vent and the Ø2” (51mm) flex intake liner to the length needed to
ensure the flex can be easily connected to the vent terminal.
3. Install the flex pipe assembly up through the chimney, ensure that the pipe slides through far enough
to connect onto the Vertical Vent Cap.
Note:
For any chimney over 15’ (4.6m), install the Sonnet 15’ 2” & 3” Flex Vent (part #50-1512)
and the Sonnet 2” & 3” Flex Couplers (part #50-1513). Place a bead of sealant on the coupler (Mill-
Pac Black sealant for the Ø3” (76mm) and high temperature silicone for the Ø2” (51mm)) Slide the
meeting ends of the flex over the coupler and fasten each joint in place with three (3) sheet metal
screws through the flex and into the coupler.
4. The Vertical Vent Cap can be installed onto chimneys with flue openings up to 16” (406mm) x 16”
(406mm) and the actual flashing is 18”x18” (refer to Figure 41). If the chimney is smaller the cap
should be trimmed down and folded
over.
5. Apply a bead of Mill-Pac Black sealant to
the top section of the Ø3” (76mm) vent
collar plate. Slide the Ø3” (76mm) flex
vent over the flue collar and secure with
three (3) sheet metal screws evenly
spaced.
Note:
If the fireplace opening is lower
than 19” (483mm), remove the vent
collar plate from the top of the insert
and connect it securely to the liner as
stated in Step 4. Check for tears in the
liner at this point.
