PROPER BURN PRACTICES
FOR MAXIMUM EFFICIENCY AND SAFETY!
• The chimney is one of the most important elements of the furnace. If the chimney is not
connected properly and installed according to manufacturer’s specication and national and
local codes, the unit is not safe and will not burn efciently. Lack of proper chimney installation
will cause unit to produce more smoke and less heat output. See Pages 5-10 of this manual to
ensure proper installation.
• Proper use of all electrical components is essential. The wall thermostat must be hooked up to
the furnace and located within the heated area of the home.
• To maximize the performance of the furnace, the draft blower may not be adjusted or altered in
any manner.
• Wood that is properly cut and stored to dry will produce more BTUs and higher heat output
than wood that has a higher moisture content. Wood with higher moisture content will create
creosote in the chimney and cause ue res.
• There should be no alteration of the Shelter furnace in any way, as this will void the UL391 safety
listing and affect the operation of the furnace. This will also void the warranty of the unit.
• Shelter makes two types of units, indoor as well as outdoor furnaces. The indoor units are
manufactured and tested for indoor applications only. They are not meant to go outside the
house but must be placed indoors in a basement or utility room. Any indoor unit placed
outside the home in a shed or building will void warranty, violate the safety listing, and will not
produce the maximum efciency possible with this unit. For outdoor applications please use
model SF4200.
• Indoor units many not be installed in mobile homes.

General Information
The Shelter 2020 EPA-Certied 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 insulated stainless steel panels to ensure many years of
energy efcient service. The design of the secondary combustion chamber increases fuel efciency by creating a “secondary burn”
of smoke and wood gases before they are vented up the chimney. The cast iron doors are custom tted to provide an airtight seal,
greatly extending the burn time and ensuring maximum efciency in fuel consumption. The heavy-gage cast iron grate allows for
convenient ash removal and reduced maintenance.
For total comfort and convenience, a thermostatically-controlled Draft Blower and fan-limit-controlled Circulation Blower are
included. These fully automatic components provide heat disbursement throughout your home, minimizing recovery time when
the wall thermostat demands heat.
All of these features are standard, offering you the most efcient, durable, and affordable indoor wood burning furnace.
Efciency was determined using the higher heating value of the fuel per B415.1-10 testing requirements. Dry seasoned wood will
develop greater BTU output. A well-insulated dwelling will always lead to better results and overall improved fuel usage efciency.
Your Shelter Furnace is designed to be either a supplemental or central heating source for your home. This wood burning furnace
may be installed in parallel with a properly operating electric, gas or oil-red central furnace, listed or certied in accordance with a
nationally recognized safety standard, and within clearances specied 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 the 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 qualied installer
should perform the installation.
Forced Hot Air Circulation:
The plenum size of your Shelter Furnace must not be reduced to less than 100 square inches, and must provide a minimum of 18
inches between the top of your Shelter Furnace and the main trunk connection. Do not modify the outer shell of the furnace at any
time. 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°F.
Clearances:
Unit must be placed on a non-combustible oor. This oor must extend at least 16 inches in front of, and 8 inches on either side of,
the fuel loading and ash removal doors; underneath the chimney connector; and 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 = 12 inches
• Sides = 6 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.

Attach “B” and “C” (side panels) to “A” (bottom panel). After the bottom and sides are assembled, attach “A” (top panel) using 6 #8
sheet metal screws provided.
4. Position the assembled lter box on rear of furnace, supporting it rmly up to electrical enclosure, covering the rear distribution blower.
Make sure the lter box is tightly pressed to the back of the furnace. Use 4 1/4” bolts (included) to rmly attach the lter box to sides of
furnace.
The lter box requires one 20” x 20” x 1” lter (not included, but
available at most hardware and home centers).
For maximum furnace efciency, inspect your lter regularly
and replace the lter when airow is restricted and the lter
appears dirty. Some environments may require more frequent
changing of the lter. Failure to replace the lter will result
in excessive temperatures causing poor performance and
damage to the furnace. It is strongly recommended to use less
restrictive, low cost lters.

wires to the terminals shown.
Chimney Types and Recommendations
See Diagram on page 9.
The chimney system is a critical element in the overall performance of the furnace. An improperly sized chimney, poor drafting chimney,
unlined chimney, or chimney failure may result in unacceptable performance of the system, product failure, and/or re and signicant
loss. Shelter strongly recommends the chimney system be professionally cleaned and inspected prior to installation. Check with local
regulations to conrm whether or not inspection is required prior to installation.
This furnace should only be connected to a clay-lined masonry chimney, masonry chimney with a properly installed SS 6” liner, or metal
all-fuel Class A HT2100 chimney system. Refer to the installation instructions from the chimney manufacturer for proper installation
methods and required clearances. Regardless of your chimney type, a minimum 6” diameter ue is required and at no time may
the chimney be greater than 12” in diameter or exceed a .08 WCI of draft. The ue draft should be conrmed using a draft gauge or
manometer. NEVER CONNECT THE FURNACE TO AN UNLINED CHIMNEY. We strongly recommend the installation of a 6” stainless
steel liner for all systems to maintain a higher ue temperature which minimizes the accumulation of creosote and improves overall
performance.
The connection of the furnace to the existing chimney may be completed using a minimum of 24-gauge single wall black stove pipe or
stainless-steel pipe. NEVER USE GALVANIZED PIPE WHICH WILL GENERATE DEADLY, POISONOUS GASES. The connection
of the furnace to the chimney may never exceed a 60” (5’) horizontal run and must maintain a minimum rise of 2 inches per foot. Never
install more than two (2) elbows when connecting to the existing chimney and the use of 45-degree elbows over one 90-degree elbow is
recommended. For easy cleaning of the chimney system, install a clean-out “T” on the rear of the furnace and never operate the furnace
without a cap installed on the clean-out access.
All piping sections should be fastened together with the proper locking bands or a minimum of three (3) screws per section. The crimped
or male end of all chimney sections should install pointing downward, towards the furnace, to form drip-free connections.
