VERTICALLY INTO EXISTING MASONRY FIREPLACE
NOTE:
Follow Vent chimney manufacturer’s instructions.
1.
Have the masonry chimney inspected by a qualified chimney sweep
or installer to determine its structural integrity.
2.
You must run a pipe from the stove outlet to 18 inches above the top
of the chimney.
3.
Install a blanking plate and the chimney pipe, and if used the outside
air pipe, as shown in Figure 20.
4.
Attach the DuraVent 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 Figures 1 & 2.
6.
Measure and build chimney top plate. Cut out holes for chimney pipe,
and if used the outside air pipe. Install and seal with flexible
waterproof sealant to prevent water leakage. Install vent cap.

INSTALLATION THROUGH SIDE OF MASONRY CHIMNEY
NOTE:
Follow Vent chimney manufacturer’s instructions.
1.
Position the stove, adhering to the clearances in Figures 1 & 2. Mark
the center of the hole where the pipe is to pierce the masonry
chimney.
2.
It will be necessary to cut out the masonry around the location of the
pipe center mark. Cut a 4-inch diameter hole for 3-inch pipe and 5-
inch diameter hole for 4-inch 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 in Figure 20.
5. Install and seal the top plate from step 3 with flexible waterproof
sealant. Slip the storm collar over the pipe, and while holding the pipe
at the proper elevation, affix the collar with a minimum of three 1/4”
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.
Install the trim collar. An adjustable pipe length and adapter may be
needed to align and complete the connection to the stove.
