Read these rules and the instructions carefully. Failure to follow them will cause a
hazard that could result in death, serious bodily injury, and/or property damage.
1. Check your local codes. The installation must comply with their rulings.
2. Do not install this furnace in a mobile home or trailer.
3. Always connect this furnace to a chimney and vent to the outside. Never vent to another
room or inside a building.
4. Do not connect this furnace to an aluminum Type B gas vent. This is not safe and is
prohibited by the National Fire Protection Association Code. This furnace requires a
masonry or UL Listed Factory Built Chimney for residential Type 103 HT or Building Heating
Appliance Chimney. Use a 6" diameter chimney or larger, that is high enough to give a good
draft. (See page 7)
5. Be sure that if a masonry chimney is used, it is safely constructed, lined and in good
repair. Have the chimney inspected by the Fire Department or an inspector.
6. Inspect chimney connector and chimney before and frequently during the heating
season for any deposit of creosote or soot which must be removed (See Chimney
Maintenance, page 15).
7. Provide air for combustion into the room where the furnace is located. If the intake is not
in the same room, air must have free access to the room.
8. CAST IRON PARTS MUST BE "SEASONED" TO AVOID CRACKING, BUILD ONLY
SMALL FIRES ON FIRST USE.
9. To prevent injury, do not allow anyone to use this furnace who is unfamiliar with the
correct operation of the furnace.
10.For further information on using your furnace safely, obtain a copy of the National Fire
Protection Association (NFPA) publication "Chimney's, Fireplaces and Solid Fuel Burning
Appliances" NFPA 211. The address of the NFPA is Batterymarch Park, Quincy, MA 02269.
11.Keep the ashpit section free of excess ashes. Do not allow ashes to stack higher than
the sides of the ash pan.
12.DISPOSAL OF ASHES- Place ashes in a metal container with a tight fitting lid. Keep
the closed container on a noncombustible floor or on the ground, well away from all
combustible materials. Keep the ashes in the closed container until all cinders have
thoroughly cooled. The ashes may be buried in the ground or picked up by a refuse collector.
13. CAUTION- The special paints used on your furnace may give off some smoke while they
are curing during first few fires., Build small fires at first. The metal used in construction of
the furnace and duct work has a light coating of oil. This could give off smoke and/or odor
from registers when furnace is used for the first time. This should disappear after a short
period of time. Once this burn-off has occurred, it should not reoccur.
14. CARING FOR PAINTED PARTS- This furnace has a painted outside jacket, which is
durable, but it will not stand rough handling or abuse. When installing your furnace, use care
in handling. Clean with soap and warm water when furnace in not hot. DO NOT use any
acids or scouring soap, as these wear and dull the finish. DISCOLORATION WILL OCCUR
IF THE FURNACE IS OVERHEATED. FOLLOW OPERATING INSTRUCTIONS
CAREFULLY.
15.Keep the feed and ash doors closed at all times except while tending the furnace.
Your Furnace is designed to be installed in a parallel air flow arrangement with a gas
or oil-fired forced air upflow-type central furnace, or it may be installed as a central
furnace.

HOW THE FURNACE FUNCTIONSHOW THE FURNACE FUNCTIONS
HOW THE FURNACE FUNCTIONS
HOW THE FURNACE FUNCTIONSHOW THE FURNACE FUNCTIONS
Y Y
Your Hotblast Furnace is designed to
Y Y
be a supplemental or central heating source
for your home. This Solid Fuel Furnace may
be installed in conjunction with a properly
operating central furnace that is listed or certified in accordance with nationally recognized safety standards and equipped with the
required controls and other safety features
and which has been installed in accordance
with appropriate standards of the National
Fire Protection Association with installation
clearances specified in the furnace nameplate marking. The installation must be accomplished by a qualified agency (one who is
engaged in, and is responsible for, or is thoroughly familiar with the installation and operation of the gas, oil, and solid fuel burning
heating appliances, who is experienced in
such work, familiar with all the requirements of
the authority having jurisdiction.) The installation shall be in strict accordance with the
manufacturer's installation instructions furnished with the solid fuel furnace.
T T
The chimney connector of the furnace is
T T
to be installed to provide clearances to combustible material not less than specified in the
individual classifications and marked on the
furnace. The chimney connector must be
connected to a chimney suitable for use with
residential type or building heating appliances
which burn solid fuel.
T T
The Furnace is designed to operate in
T T
either parallel or series air flow arrangement
with the central furnace or as a central furnace.
CENTRAL FURNACE INSTALLATION: CENTRAL FURNACE INSTALLATION:
CENTRAL FURNACE INSTALLATION: As
CENTRAL FURNACE INSTALLATION: CENTRAL FURNACE INSTALLATION:
a central furnace, the unit functions independently of any other system. The blower will
come on when the plenum temperature
reaches the setting on the blower control.
PARALLEL INSTALLATIONPARALLEL INSTALLATION
PARALLEL INSTALLATION: (U.S. ONLY)
PARALLEL INSTALLATIONPARALLEL INSTALLATION
(See Optional Wiring Diagram, Page 13, Fig.
14) The design is such that when the blower
comes on, the blower on the central system
also comes on. The blower will only come on
when the temperature in the plenum has
reached the setting on the blower control.
This is to insure that there is sufficient warm air
in the system to make it efficient for the unit to
operate. When the central system thermostat
calls for heat, the central system will operate
by the burner igniting and the blower coming
on. It is possible that both systems will operate
simultaneously. It is recommended that for the
most efficient use of your Hotblast Furnace,
that it be fired as much as possible in order to
reduce the demand on your existing central
heating system. This unit has an optional
forced draft kit that operates from a wall thermostat. When the temperature falls below the
setting on the wall thermostat, the forced draft
will come on (U.S. Stove Option 11/DKU)
T T
The warm air supply outlet of the Hotblast
T T
Furnace shall not be connected to the cold air
return of the central furnace, because the possibility exists of components of the central
furnace overheating and causing the central
furnace to operate other than is intended.

Check figures 2 and 3. Be sure you
have the clearances shown from the
furnace and the connector pipe to
combustible surfaces. If you have a
solid brick or stone wall behind your
furnace, you can place the furnace
as close as you wish to the wall. If the
wall is only faced with brick or stone,
treat it as a combustible wall.

Before using an existing masonry chimney, clean the chimney and inspect the flue liner to be sure
it is safe to use. Make repairs before attaching the furnace. See page 4, item 5. Look at Fig. 4. The
connector pipe and fittings you will need to connect directly to a masonry chimney are shown.
The chimney connection should be as short as possible.
If the connector pipe must go through a combustible wall before entering the masonry chimney,
consult a qualified mason or chimney dealer. The installation must conform to local fire codes, and
N.F.P.A. 211.

Carefully follow chimney manufacturer's instructions. Use only a Listed Residential Type or
Building Heating Appliance Chimney. If your chimney starts at the ceiling (Fig. 5), you will need
enough 6" pipe to reach the ceiling.
The top of the chimney must be at least 3 feet above the roof and be at least 2 feet higher than any
point of the roof within 10 feet (Fig. 5).
