EPA Certified to the Warm Air Furnace NSPS requirements, for sale May 2017 through May 2020.
SAVE THESE INSTRUCTIONS
Congratulations! You have selected the finest quality outdoor wood burning 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 rulings and requirements.
• This furnace is an outdoor hot air furnace and must not be altered in any way.
• This furnace requires a back-up electric generator, 2000 watts minimum, in case of power failure.
• Always have a properly installed and functioning smoke detector installed 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.
• When making plans to install your outdoor furnace, the first thing you need to think about is the placement of the
unit. Although you can install the Shelter Furnace up to 30 feet from the home, a much shorter distance is
recommended to provide better airflow. The furnace has been tested for clearance of 12 inches from the home;
this would give maximum airflow and provide the highest efficiency.
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 furnace, you find damage has occurred during transit,
notify your dealer immediately. Your dealer will advise you what actions must be taken to correct the problem.
