3.3.4 Vent installation
3.3.4.1 Acceptable configurations
The stove must be connected to Simpson GS Dura Vent or Security Chimneys International (Secure
Vent) 4” x 6 5/8” venting. Install the vent components according to the manufacturer's instructions.
Use a maximum of two 90 degree elbows and four 45 degree elbows. Slope horizontal pipe at least
1/4" (6 mm) rise per foot of horizontal run. Allow 2" (50 mm) clearance to the vent. A vinyl siding
standoff must be used when terminating horizontally to vinyl siding as well a heat guard must be
installed when using a 36" snorkel. Refer to the graph for allowable vent configurations.
Note: If at any time the vent-air intake piping is dismantled, use the vent manufacturer’s instructions
and the sealing instructions for reassembly.
For horizontal termination:
The maximum horizontal length using the minimum vertical length must consist of:
• A minimum of 6 feet (1.82m) of vertical length directly on top of stove.
• One 90 degree elbow.
• A maximum of 10 feet (3m) of horizontal length.
• A wall thimble.
• A wall thimble cover.
• A horizontal termination cap.

13
The minimum vertical length using the maximum horizontal length consists of:
• A minimum of 24” (61cm) vertical length directly on top of the stove.
• A maximum of one 90 degree elbow.
• A maximum of 12” (31cm) total horizontal length.
• A wall thimble.
• A wall thimble cover.
• Horizontal termination cap.
For vertical termination:
The maximum vertical system consists of:
• Up to 30 feet (9m) of vertical length.
• Fire stop, flashing, and collar.
• High Wind termination cap.
Use a ceiling fire stop when penetrating a ceiling. Use a round support box/wall thimble when

3.3.4.3 Use of sealant
Sealant is required on vent system joints. On longer vent runs, especially vertical runs, sealant will
ensure that the combustion air enters from outdoors, and not through the vent joints. Use a sealing
product, available from your local Drolet dealer, on the inner pipe joint, applying the sealant around
the outside of the male part of the vent. A bead of silicone should be used on the outside of the joint
after assembly to seal the supply air.
“WARNING: A minimum clearance to combustibles must be maintained around the vent pipe of 2” on
horizontal pipe runs and 1” on vertical pipe runs.
Apply RTV high temperature sealant around male
pipe.
Figure 6

16
3.3.4.4 Horizontal wall vent termination
The position of the horizontal vent termination must be positioned in such a way as to meet all local building
codes. Attach the correct length of vertical section pipe and an elbow fitting to the stove. Mark the center line
of the pipe facing the wall (allowing for a 1/4” rise per foot of horizontal, example 10 ft of horizontal would
require a rise of 2.5”).
NOTE: ALLOWING THE VENT PIPE TO SLOPE DOWN TOWARDS THE VENT TERMINATION COULD
CAUSE POOR COMBUSTION AND/OR HIGH TEMPERTURES THAT MAY PRESENT A FIRE HAZARD.
Mark a 10” x 10” square around the center mark (inside dimensions).Cut and frame the exterior wall to except
the wall thimble. Install the wall thimble shield using wood screws. If the wall being penetrated is constructed of
non-combustible material, a 7” hole for the vent pipe is acceptable.
Caution: When installing the terminal on to
vinyl siding, a vinyl siding kit or furring strips
must be used to prevent the terminal from
being recessed into the siding.
When the termination is to be attached to vinyl
siding, apply a bead of non-hardening mastic
around the outside edge to form a seal between
the standoff and the terminal. Attach the terminal
to the exterior wall using four wood screws
through the holes in the corner of the vent
terminal. Complete the terminal installation;
apply a bead of mastic around the outer edge of
the vinyl standoff. With the termination installed
you can now connect the completed vent
assembly by sliding the unit back towards the
wall and carefully inserting the pipe into the
terminal. Before the final connection is made
slide on the decorative wall thimble. Secure the
terminal by securing the termination straps to the
pipe as close to the exterior wall as possible
using sheet metal screws, ensure that the straps
are hidden by the wall thimble cover. Apply
decorative trim if required.
Before sliding the pipe into the termination, ensure that you have slid the decorative wall thimble cover and
penetration heat shield over the pipe.
Slide the pipe into the vent, making sure that at least 11/4” overlap between the pipe and the terminal. Attach
the pipe by attaching two sheet metal screws through the terminal straps and into the pipe. Bend back the
straps towards the terminal making sure they are hidden by the decorative thimble. Finally attach the wall
penetration heat shield and secure with wood screws

Basement Installations
To achieve the minimum vertical rise a 36” snorkel must be used. Where the bottom of the terminal may be
blocked by snow, ensure provision is made for adequate drainage.
3.3.4.5 Vertical installation
Always maintain a 1” clearance around the vent pipe (vertical) and 2” clearance horizontal, when passing
through ceilings, walls, roofs, enclosures, attic rafter or any combustible surfaces.
DO NOT PACK AIR SPACES WITH INSULATION.
Refer to the vent charts for maximum allowable vertical and horizontal allowable installations.
When planning your installation determine if ceiling joists, roof rafters or other framing will obstruct the vent
system. You may have to use 45° elbows to navigate around any obstacles. When passing through a flat
ceiling install a Box/Wall thimble. Cut a 10” square hole and frame as shown in the diagram opposite.
Ensure all pipe sections are fully twist locked.
NOTE: ALWAYS CHECK YOUR LOCAL CODES BEFORE INSTALLING VENTING. CLEARANCES ETC, MAY VARY
FROM STATE TO STATE (PROVINCE TO PROVINCE).
NOTE: CONSULT DURAVENT PARTS LIST OR SECURITY CHIMNEY PARTS LIST FOR PART NUMBERS (USE
ONLY DURAVENT GS SYSTEM OR SECURITY DV PARTS).
