VERTICAL VENTING INSTALLATION
For safe and proper operation of the fireplace, follow the
venting instructions exactly.
All inner exhaust and outer intake vent pipe joints may
be sealed using either Red Rtv high temp silicone seal-
ant or Black high temp Mill Pac with the exception of the
fireplace exhaust flue collar which must be sealed using
mill Pac (not supplied).
1. Move the fireplace into position.
2. Fasten the roof support to the roof using the screws
provided. FIGURe 60. The roof support is optional. In this
case the venting is to be adequately supported using either
an alternate method suitable to the authority having jurisdic-
tion or the optional roof support.
3. Apply high temperature sealant to the outer edge of
the inner sleeve of the air terminal. Slip a 4" diameter cou-
pler a minimum of " over the exhaust and secure using 
screws.
4. Apply high temperature sealant to the outer edge of the
of the outside sleeve of the air terminal. Slip a 7" diameter
coupler over the air intake vent pipe and secure as before.
Trim the air intake liner coupler even with the exhaust cou-
pler end.
5. Thread the air terminal pipe
assembly down through the roof
support and attach, ensuring
that a minimum 6" of air termi-
nal 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 assembly as it is
passed through the attic. The
air terminal must be located
vertically and plumb.
6. Remove nails from the shingles, above and to the sides
of the chimney. Place the flashing over the air terminal and
slide it underneath the sides and upper edge of the shingles.
Ensure that the air terminal is properly centered within the
flashing, giving a 3/4" margin all around. Fasten to the roof.
Do NOT nail through the lower portion of the flashing. Make
weather-tight by sealing with caulking. Where possible,
cover the sides and top edges of the flashing with roofing
material.
7. Apply a heavy bead of waterproof caulking  inches
above the flashing. Slide the storm collar around the air
terminal and down to the caulking. Tighten to ensure that a
weather-tight seal between the air terminal and the collar is
achieved. Attach the other storm collar centered between the
air intake and air exhaust slots onto the air terminal. Tighten
securely. Attach the rain cap.
8. Continue adding rigid venting sections, sealing and
securing as above. Attach an exhaust adjustable vent to
the last section of rigid piping. Secure with screws and
seal. Repeat using an air intake vent pipe adjustable vent.
(BGd36cF ONly: Before attaching elbows to the
collars on the back of the fireplace, 1½" will need
to be trimmed off the exhaust liner collar.)

9. REaR VENT applIcaTION: Run a bead of high tem-
perature sealant around the outside of the exhaust elbow.
Pull the adjustable pipe a minimum " onto the elbow. Secure
with  screws. Repeat with
the inner air intake vent pipe
adjustable vent.
TOp VENT applIcaTION:
Run a bead of high tem-
perature sealant around the
outside of the 4" collar on the
fireplace. Pull the adjustable
pipe a minimum of " onto the
collar. Secure with  screws.
Repeat with the 7" adjustable
vent.
10. 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 filling up the 1" air space around the pipe.
RESTRICTING VERTICAL VENTS
BGd42cF ONly: Vertical terminations may display a very
active flame. As this appearance is not desirable, the vent exit
must be restricted using restrictor plate, W500-005. This
reduces the velocity of the exhaust gases, slowing down the
flame pattern and creating a more traditional appearance. The
plate has a series of holes to allow for adjustment.
Remove the two screws on either side of the exhaust collar
inside the firebox. Install the plate as shown. Install the plate
on the desired set of holes then replace the screws.

GAS INSTALLATION
1. Move the fireplace into position and secure using the
nailing tabs and/or secure to the floor through the ¼"ø holes
located at either end of the base.
2. Route a /" n.P.T. black iron gas line, /" type-L copper
tubing or equivalent to the fireplace.
3. For ease of accessibility, an optional remote wall switch
or millivolt thermostat may be installed in a convenient lo-
cation. Route -strand (solid core) millivolt wire through the
electrical hole located at the bottom left side of the unit. The
recommended maximum lead length depends on wire size:
