General Information
The Shelter Furnace has been engineered to accommodate the heating requirements of the average sized home, even during winter’s
coldest months. It is constructed with high grade, heavy gauge steel and is continuously welded to assure the highest structural strength.
In addition, the firebox is lined with firebrick to ensure many years of energy efficient service. The design of the secondary combustion
chamber increases fuel efficiency by creating a “secondary burn” of smoke and wood gases before they are vented up the chimney. The
cast iron doors are custom fitted to provide an airtight seal, greatly extending the burn time and ensuring maximum efficiency in fuel
consumption. The heavy-gauge cast iron shaker grate, designed for maximum heat transfer, allows for convenient ash removal and
reduced maintenance.
For total comfort and convenience, a thermostatically controlled draft and circulation blower system is included. These fully automatic
components furnish rapid heat disbursement throughout your home, minimizing recovery time when the wall thermostat demands heat.
All of these features are standard, offering you the most efficient, durable and affordable indoor wood and coal burning furnace.
Your Shelter Furnace is designed to be either a supplemental or central heating source for your home. This wood and coal burning
furnace may be installed in parallel with a properly operating electric, gas or oil-fired central furnace, listed or certified in accordance
with a nationally recognized safety standard, and within clearances specified on the Shelter Furnace nameplate. When in a parallel
installation the static pressure of the central furnace plenum may not exceed 0.15 water column inches and the maximum setting on
central furnace limit switch is 182°F. With the Shelter Furnace in an “Interconnection Arrangement” your furnace should be upstream
of the central furnace. The Shelter Furnace warm air supply should never be connected to return air for the central furnace. A qualified
installer should perform the installation.

Forced Hot Air Circulation:
The plenum size of your Shelter Furnace must not be reduced to less than 12 inches in diameter or 113 square inches, and must provide
a minimum of 18 inches between the top of your Shelter Furnace and the main trunk connection. The plenum attached to the furnace
must be constructed of metal. The warm air supply duct system should be constructed of materials with a minimum temperature rating of
250° Fahrenheit.
Clearances:
Unit must be placed on a non-combustible floor. This floor must extend at least 16 inches in front, 8 inches on either side of fuel loading
and ash removal doors, underneath the chimney connector and must extend 2 inches on either side of the chimney connector. The
furnace must maintain the following clearances to combustibles:
• Heat plenum = 2 inches
• Chimney connector = 18 inches
• Front = 48 inches
• Rear = 31 inches
• Sides = 12 inches
• Main furnace = 12 inches
These are minimum clearances and should be strictly followed. In the case of a power outage, a dangerous level of heat accumulation
may develop. Do not store fuel or other combustible materials within installation clearances.
Location and Installation
NOTE: Before beginning installation, consult proper local authorities regarding local codes governing all such applications and
installations.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. Your furnace must be placed on a non-
