1. Attach 4" and 7" elbows to the fi replace. Apply high temperature sealant W573-0007
(not supplied) and secure the joints with 3 screws.
2. Move the fi replace into position.
3. Fasten the roof support to the roof using the screws provided.The roof support is optional.
The venting is to be adequately supported using either an alternate method suitable to the
authority having jurisdiction or the optional roof support.
4. Apply high temperature sealant W573-0007 (not supplied) to the outer edge of the inner
pipe of the air terminal connector. Slip the 4" rigid vent pipe pipe a minimum of 2" over the
inner pipe of the air terminal connector and secure using 3 screws.
5. Apply high temperature sealant W573-0002 (not supplied) to the outer edge of the of the
outter pipe of the air terminal connector. Slip the 7" rigid vent pipe over the outer pipe of the
air terminal connector and secure as before. Trim the 7" rigid vent pipe even with the end of
the 4" rigid vent pipe.
6. Thread the air terminal connector / vent pipe assembly down through the roof support
and attach, ensuring that a minimum 16" of air terminal connector will penetrate the roof when
fastened.
If the attic space is tight, we recommend threading the Wolf Steel vent pipe collar or
equivalent loosely onto the air terminal connecter / vent pipe assembly as it is passed through
the attic. The air terminal connector must be located vertically and plumb.
7. Remove nails from the shingles, above and to the sides of the chimney. Place the fl ashing
over the air terminal connector and slide it underneath the sides and upper edge of the shingles.
Ensure that the air terminal connector is properly centered within the fl ashing, giving a
all around. Fasten to the roof. Do NOT nail through the lower portion of the fl ashing. Make weather-
tight by sealing with caulking. Where possible, cover the sides and top edges of the fl ashing with
roofi ng material.
8. Aligning the seams of the terminal and air terminal connector, place the terminal over the air terminal connector making
sure the vent pipe goes into the hole in the terminal. Secure with the three screws provided.
9. Apply a heavy bead of weatherproof caulking 2" above the fl ashing. Note: Maintain a minimum 2" space between the
air inlet base and the storm collar. Install the storm collar around the air terminal and slide down to the caulking. Tighten to
ensure that a weather-tight seal between the air terminal and the collar is achieved.
10. Continue adding rigid vent pipe sections, sealing and securing as above. Attach a 4" collapsed telescopic sleeve to
the last section of rigid piping. Secure with screws and seal. Repeat using a 7" telescopic sleeve.
11. Run a bead of high temperature sealant W573-0007 (not supplied) around the outside of the 4" elbow. Pull the telescopic
sleeve a minimum 2" onto the elbow. Secure with 3 screws. Repeat with the 7" telescopic sleeve.
12. In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent any
materials, such as insulation, from fi lling up the 1" air space around the pipe.
GD33 RESTRICTING
VERTICAL VENTS
Vertical installations may
display a very active flame.
If this appearance is not
desirable, remove the baffl e
plate from the rear wall of the
fi rebox, exposing the fl ue gas
outlet opening. Reverse the
restrictor plate, superimposing
the flue outlet hole with
the smaller restrictor plate
opening. Replace the baffle
plate. This reduces the velocity
of the exhaust gases, slowing
down the flame pattern and
creating a more traditional
fl ame appearance.

Warning:
This restrictor (located
in the lower valve
compartment) must
not be installed on
any vent confi guration
that has a horizontal
termination or vertical
vent with vertical termination less than 10'. Vertical
installations over 10' may display a very active fl ame. If
this appearance is not desirable, install the restrictor plate.
This reduces the velocity of the exhaust gases, slowing
down the fl ame pattern and creating a more traditional
fl ame appearance.
