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 rebox is lined with rebrick to ensure many years of energy efcient service. The cast iron doors are custom tted to

provide an airtight seal, greatly extending the burn time and ensuring maximum efciency in fuel consumption. The heavy-gauge cast

iron grate, designed for maximum heat transfer, allows for convenient ash removal and reduced maintenance.

For comfort and convenience, a draft control and circulation blower system is included. These components furnish rapid heat

disbursement throughout your home. All of these features are standard, offering you the most efcient, 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-red central furnace, listed or certied in accordance

with a nationally recognized safety standard, and within clearances specied on the 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 qualied installer should perform

the installation.

Forced Hot Air Circulation:

The plenum size of your Shelter Furnace must not be reduced to less than 10 inches in diameter or 79 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 oor. This oor must extend at least 16 inches in front, 8 inches on either side of fuel loading

door and ash removal, 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

noncombustible oor. Position the furnace as close to the chimney as possible. Air for combustion must be provided into the room where

the furnace is located. Allow air free access to the furnace for combustion and ventilation.
