SAVE THESE INSTRUCTIONS

Congratulations! You have selected the finest quality wood and coal burning indoor furnace, manufactured with pride in the

USA. Please take a few moments to carefully read the owner’s manual. By taking the time to familiarize yourself with your

new Shelter Furnace, you will be able to look forward to years of trouble-free, dependable service.

Installation:

First: Check local codes. The installation must comply with all local rules and requirements.

Furnace installation is to be performed by a qualified installer. This furnace must not be installed in trailers, modular or mobile

homes. Always have a properly installed and functioning smoke detector in your home. To prevent accidental injury, do not

allow anyone who is unfamiliar with the furnace to operate it. Spend time familiarizing yourself with your Shelter Furnace,

especially the different settings and the effects they have on burn patterns. It is impossible to predict how each setting will

affect your furnace due to variations in conditions, fuels and temperatures.

Transportation Damage:

Every effort has been made to ensure that your Shelter Furnace will arrive in perfect condition. Any visible damage should be

noted on the freight bill at the time of delivery. If upon unpacking your Shelter Furnace you find damage has occurred during

transit, notify your supplier immediately. Your supplier will advise you what actions must be taken to address the problem.

Disclaimer Notice:

The listed BTU rating for your new Shelter Furnace was obtained using laboratory calculations. The actual BTU output you

experience may vary somewhat depending on the type, condition and moisture content of the fuel used, damper adjustment,

chimney type and other factors. Therefore, the manufacturer disclaims any guarantee as to the BTU output or capacity.

Shelter Furnace disclaims any responsibility for the following: installation of a furnace that has been altered or modified in any

way; installation of the furnace other than as instructed in this manual; installation and/or use of any component or part not

approved by Shelter Furnace for use with this furnace. Be sure to complete and return your warranty card within 30 days of

purchase in order to activate warranty coverage on your furnace.

Manufacturer’s Notice:

Please be advised that we periodically make changes to improve our products, therefore the information in this manual may

not be completely applicable to your Shelter Furnace. Please refer to markings on the appliance for additional information.
