Adapters are available to adapt from 3” (77 mm) PL-Vent to 6” or
8” (153 mm or 204 mm) Class-A chimney. As an alternative, 3” or
4” (77 mm or 102 mm) PL-Vent can be run inside existing chimney
to termination. This is the preferred method. Follow guidelines for
equivalent vent length.
E. VERTICALLY INTO EXISTING MASONRY FIREPLACE
NOTE: Follow PL-Vent chimney manufacturer’s instructions.
1. Have the masonry chimney inspected by a qualified chimney
sweep or installer to determine its structural condition.
2. You will need a pipe length equal to the chimney height from the
hearth. If outside combustion air is to be used, you will need a
pipe length equal to the chimney height plus 18” (458 mm).
3. Install a blanking plate and the chimney pipe, and if used the
outside air pipe, as shown in.
4. Attach the PL-Vent adapter, a section of pipe and clean out tee,
making sure the clean out tee is centered in the chimney flue
area. Use RTV, metallic tape, and a minImum of three self-
taping screws at all joint connections to ensure a tight seal.
5. Position the stove, adhering to the clearances in.
6. Measure and build chimney top plate. Cut out holes for chimney
pipe, and if used the outside air pipe. Install and seal with non-
hardening mastic to prevent water leakage. Install vent cap.
F. INSTALLATION THROUGH SIDE OF MASONRY CHIMNEY
NOTE: Follow PL-Vent chimney manufacturer’s instructions.
1. Position the stove, adhering to the clearances. Mark the center
of the hole where the pipe is to pierce the masonry chimney.
2. It will be necessary to break out the masonry around the location
of the pipe center mark. Use a 4” (102 mm) diameter hole for
3” (77 mm) pipe and 5” (127 mm) diameter hole for 4” (102 mm)
pipe.
3. Measure and build chimney top plate. Cut out holes for chimney
pipe, and if used the outside air pipe.
4. Install the tee on the bottom of the vertical pipe system and
lower it down the chimney until the center branch of the tee is
level with the center of the hole in the masonry, as shown.
5. Install and seal the top plate from step 3 with non-hardening
mastic. Slip the storm collar over the pipe, and while holding the
pipe at the proper elevation, affix the collar with a mini mum of
three 1/4” (7 mm) stainless steel sheet metal screws. Seal all
joints and seams around the collar.
6. Connect the horizontal pipe by pushing it through the hole in the
masonry and lining it up with the branch in the tee. Push the pipe
into the tee while twisting it to lock it into the tee.
7. If desired, once the horizontal pipe is in place, the space between
the pipe and masonry may be filled with high temperature grout.
8. Install the trim collar. An adjustable pipe length and adapter may
be needed to finish the connection to the stove.
INSERT INSTALLATIONS
Insert installations must be vented with 3” or 4” (77 mm or 102
mm) pipe. Pipe may be single wall stainless steel flexible pipe. Vent
may terminate within chimney beyond a blanking plate or extend
to the chimney top, see “Combustion Air Supply” for outside air
access information. The fireplace and chimney should be cleaned
thoroughly before starting the installation. We suggest painting the
interior of particularly old and dirty fireplaces to seal any odors. In
zero-clearance fireplace installations, when the fireplace opening is
above the floor or raised hearth, the adjustable legs” can be used to
bridge the gap between the hearth and stove bottom.
