EPA Approved Wood Fireplace

Sweepy Zero clearance wood fireplaces are designed to be installed where no fireplace currently exists. Backed up to a combustible wall or inserted into an opening cut into the wall and then framed in with standard wood framing, zero clearance wood fireplaces are an ideal way to add a fireplace to your construction or remodel plans without the expense & hassle of a masonry fireplace structure.

Most zero clearance wood fireplaces are extremely inefficient, sending 90% of the heat from the fire (and 40 - 60 grams/hr of unburned particulates) up the chimney. The Hearthstone Montgomery WFP75 is different. The Montgomery is a high-efficiency, EPA approved woodstove encased in a zero clearance cabinet so it can be built into the wall like any fireplace!

Chimney Height Rules Diagram

The Montgomery WFP-75 must be installed using at least 12' of 6" ASHT chimney. Here's how to figure out how many feet of chimney an installation will require:

The chimney must extend from the fireplace to a point at least 3' above the roof, and also 2' above any part of the roof within 10'. Example: If the roof peaks at 13' above the floor, and the peak is within 10' of the chimney location, the chimney will need to rise to a point 15' above the floor. We subtract the 3' height of the fireplace to determine that a 12' chimney kit is needed.
