Harman Stove Company P35I D. Existing Fireplace Installation, Non-combustible Insulation

P35i Fireplace Insert

D. Existing Fireplace Installation:

If using a short run of venting, whether flex or rigid, through the damper and into the chimney flue; The Damper must be removed or locked in the open posi- tion and sealed with a plate constructed of steel or other non-combustible material.

Kaowool, mineral wool or other non-combustible insu- lation is recommended above the plate to reduce the possibility of condensation. You will also need to wrap the venting section between the insert frame and the damper sealing plate. This is to prevent overheating of the fireplace cavity, which may cause damage to the insert's motors and other electrical components. The connector pipe should extend through the sealing plate and smoke chamber and into, or beyond the first flue tile.

Be sure to design the venting so that it can be easily cleaned.

Check with your local authority having jurisdiction to determine if this venting method is acceptable. Some Provincial, State, or Local codes may require a full liner run to the top of the chimney. Be sure and check your local regulations before planning the installation. In this method, the proper flashing and rain cap are also required.
