Frequently Bought Together


This zero clearance conversion kit for Harman pellet inserts was specifically designed for the Accentra Insert (2003-2012) but can be used for all Harman pellet inserts when installing the unit into any pre-existing zero clearance application where the specific Harman zero clearance box intended for your unit is not being used.

For example, Your home has an old manufactured wood-burning fireplace (not made from bricks or stone). The fireplace is going to have a metal box that protects the home's wooden frame from excessive heat transfer. In many scenarios, the cost to remove the entire shell and replace it with Harmans zero clearance box is cost-prohibitive. Wrapping the section of vent that passes through the top of the box with this insulation will allow you to use the existing z-box.

This kit is necessary to retrofit a Harman pellet stove insert into any pre-existing factory-built wood-burning fireplace.

Includes 36" of 24 Gauge Wire, HWH TEK 10 x 3/4, Flue Insulation, Modification Label, and Installation Instructions.
