INSERT INSTALLATION

The detailed instructions required to assemble the faceplate are supplied with the faceplate kit.

INSERT INTO EXISTING MASONRY FIREPLACE

NOTE: Follow pipe manufacturer's instructions.
1. Have the masonry chimney inspected by a qualified
chimney sweep or installer to determine its structural
integrity.
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
inches
3. Install a sealing cap at the top and bottom chimney
4. You can install a fresh air intake as per Figure 24:
Option A through the floor
-
Option B through the back wall
-
- Option C through chimney top
5. 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.
*Minimum fireplace opening 23"W x 23"D x 20"H
Measure and build the chimney's top sealing plate. Cut out holes for
chimney pipe and outside air pipe (if necessary). Install and seal with
flexible sealant to prevent water leakage. Install vent cap.
