WinterWarm Fireplace Insert or System
2000941
Introduction
Thank you for purchasing a Vermont Castings’ WinterWarm, an efficient fireplace carefully engineered to bring you the
latest in wood combustion principles and modern foundry technology.
The WinterWarm masonry Fireplace Insert turns a traditional masonry fireplace into a powerful heater; the Winter-
Warm Fireplace System combines an insulated metal cabinet with the Fireplace Insert so that it may be installed in
close-clearance situations where no masonry fireplace and chimney exists.
Whichever you have purchased, you can count on years of comfortable heating and pleasureable fire viewing if you
treat it properly and operate it according to the directions in this owner’s guide.
The WinterWarm Fireplace Insert, and the WinterWarm Fireplace System that utilizes the WinterWarm Fireplace
Insert, are listed by Underwriter’s Laboratories of Canada, and are in compliance with the standards set forth by the
Federal Environmental Protection Agency, 40 CFR Part 60.532(b), as stated on the permanent label attached to each
appliance.
This manual describes the installation and operation of the WinterWarm catalytic-equipped wood heater. This heater
meets the U.S. Environmental Protection Agency’s emission limits for wood heaters sold after July 1, 1990. Under
specific test conditions this heater has been shown to deliver heat at a rate ranging from 10,300 to 30,000 Btu’s/hr.
For more complete details on WinterWarm performance and specifications, please refer to page 3.
The WinterWarm is designed, tested and listed for burning wood. Do not burn other fuels.
We recommend that you hire a professional installer certified by Wood Energy Technical Training (WETT) to install
your WinterWarm, or to advise you on the installation should you attempt to install it yourself.
