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.
