WinterWarm Small Insert

Introduction

Thank you for purchasing a Vermont Castings WinterWarm Small Insert, an efficient fireplace carefully engineered to bring you the latest in wood combustion principles and modern foundry technology.

While it can be used to transform a traditional masonry fireplace into a powerful heater, it is also designed to be in- stalled into a listed factory-built fireplace where no masonry fireplace and chimney exists.

Whichever installation you have chosen, you can count on years of comfortable heating and pleasurable fire-viewing if you operate and maintain it according to the directions in this Owner’s Guide.

The WinterWarm Small Insert has been tested and listed by Inchcape Testing Services / Warnock Hersey Inc. of Middleton, Wisconsin according to ANSI/UL 1482 for the United States and ULC S628 for Canada. The WinterWarm Small Insert is listed to, and 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 Small Insert 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 8,700 to 31,000 Btu/Hr.

For more complete details on WinterWarm Small Insert performance and specifications, please refer to Page 3. The WinterWarm Small Insert is designed, tested and listed for burning wood. Do not burn other fuels.
