Rules for safe installation and operation  
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 a UL/ULC  
Listed Factory Built Chimney for residential type 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 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 18).  
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. Forfurtherinformationonusingyourfurnacesafely, obtainacopyofthe NationalFireProtection  
Association (NFPA) publication "Chimney's, Fireplaces and Solid Fuel Burning Appliances" NFPA  
211. The address of the NFPA is Batterymarch Park, Quincy, MA 02269. For more information on  
Canadian installation, obtain a copy of CAN/CSA-B365-M91 Installation Code for Solid-Fuel-  
Burning Appliances and Equipment.  
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  
containeronanoncombustiblefloororontheground,wellawayfromallcombustiblematerials. 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 FUNCTIONS  
PARALLEL INSTALLATION: (U.S. ONLY)  
Your HOTBLAST Furnace is designed  
tobeasupplementalorcentralheatingsource  
for your home. This Solid Fuel Furnace may  
be installed in conjunction with a properly  
operating central furnace that is listed or cer-  
tified in accordance with nationally recog-  
nized 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 name-  
plate marking. The installation must be ac-  
complished by a qualified agency (one who is  
engaged in, and is responsible for, or is thor-  
oughly familiar with the installation and op-  
eration of the gas, oil, and solid fuel burning  
heating appliances, who is experienced in  
suchwork,familiarwithalltherequirementsof  
the authority having jurisdiction.) The instal-  
lation shall be in strict accordance with the  
manufacturer's installation instructions fur-  
nished with the solid fuel furnace.  
(See Optional Wiring Diagram, Page 16, Fig.  
15) 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.  
Thisistoinsurethatthereissufficientwarmair  
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. Itispossiblethatbothsystemswilloperate  
simultaneously. Itisrecommendedthatforthe  
most efficient use of your HOTBLAST Fur-  
nace, that it be fired as much as possible in  
order to reduce the demand on your existing  
central heating system. This unit has an op-  
tional forced draft kit that operates from a wall  
thermostat. Whenthetemperaturefallsbelow  
the setting on the wall thermostat, the forced  
draftwillcomeon(U.S.StoveOption11/DKU)  
The warm air supply outlet of the  
HOTBLAST 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 caus-  
ing the central furnace to operate other than is  
intended.  
The chimney connector of the furnace is  
to be installed to provide clearances to com-  
bustible 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  
residentialtypeorbuildingheatingappliances  
which burn solid fuel.  
SERIES INSTALLATION: (U.S. & CANADA)  
This type of installation uses only the blowers  
of the existing central furnace. The solid fuel  
fan/limitcontrolmustalsocontrolthefunctions  
of the existing furnace. All electrical power  
must come from a single branch circuit (See  
Fig. 15).  
The Furnace is designed to operate in  
either parallel or series air flow arrangement  
with the central furnace or as a central fur-  
nace.  
CENTRAL FURNACE INSTALLATION: As  
a central furnace, the unit functions indepen-  
dently of any other system. The blower will  
come on when the plenum temperature  
reaches the setting on the blower control.

MASONRY CHIMNEY  
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.  
DO NOT CONNECT THIS FURNACE TO A CHIMNEY FLUE SERVING ANOTHER APPLI-  
ANCE.  
The chimney used for a furnace must not be used to ventilate the cellar or basement. If there is  
a cleanout opening at the base of the chimney, close it tightly.

Rules for Connector  
Pipe Installation  
NOTE:  
1. The crimped end of the chimney connector fits  
inside the furnace flue collar. Install additional chim-  
ney connectors and elbow with the CRIMPED END  
TOWARD THE FURNACE. This will allow any  
condensation in the flue to run back into the furnace.  
Use 6" dia. steel pipe and elbows for connection to  
chimney. Never use less than 26 gauge and al-  
though blued steel is satisfactory, high temp painted  
black is much more desirable.  
A flue pipe shall not pass through an attic,  
roofspace,closetorsimilarconcealedspace,  
a floor or ceiling of combustible construc-  
tion. Where passage through a wall or parti-  
tion is desired, installation must conform  
with UL standards.  
2. Slope any horizontal pipe upward toward the  
chimney at least 1/4 inch for each foot of horizontal  
run.  
3. You must have at least 18 inches of clearance  
between any horizontal piping and the ceiling.  
(See Fig. 3)  
4. The chimney connector must not extend into the  
chimney flue. (See Fig. 6)  
5. Seal each chimney connector pipe joint with fur-  
nace cement. Also seal the pipe at the chimney.  
6. Use 3 sheet metal screws at each chimney pipe  
joint to make the piping rigid.

7. The chimney connector may include a section for  
abarometricdraftregulatorbetweenthefurnaceand  
the chimney (Fig. 4,5, &7). The barometric draft  
regulator must be installed in the same room (same  
pressure zone) as the furnace.  
8. Install the barometric draft regulator strictly in  
accordance with the instructions that are provided  
with the barometric draft regulator.  
9. A solid damper must be used in the chimney  
connecting pipes between the flue collar and the  
chimney. When used in conjunction with a baromet-  
ric draft regulator, the solid damper must be placed  
between the barometric and the chimney. (See Fig.

surfaces on all sides. Fasteners between supports and the chimney length shall not penetrate the chimney liner.  
See Part B of Figure 8.  
3. Use a 10" diameter ventilated thimble made of at least 24 gauge(0.024") steel having two 1" air channels. The venti-  
lated thimble must be separated from combustible materials by a minimum of 6" glass fiber insulation. The opening  
in the combustible wall shall be covered and the thimble supported with sheet steel supports which are at least 24  
gauge (0.024") in thickness. The sheet steel supports shall be securely fastened to wall surfaces on all sides and  
shall be sized to fit and hold the chimney section. Fasteners used to secure chimney sections shall not penetrate  
chimney flue liner. See Part C of Figure 8.  
4. Use an 8" inside diameter solid insulated listed factory-built chimney length which has 1" or more of solid insulation.  
The minimum length of this chimney section shall be 12" and will serve as a pass-through for the 6" diameter  
chimney connector. There must be at least a 12" air space between the outer wall of the chimney section and any  
combustible materials. The chimney section shall be concentric with and spaced 1" away from the chimney connec  
tor by means of sheet steel support plates on both ends of the chimney section. The opening in the combustible wall  
shall be covered and the chimney section supported on both sides with sheet steel supports which are at least 24  
gauge (0.024") in thickness. The sheet steel supports shall be securely fastened to wall surfaces on all sides and  
shall be sized to fit and hold the chimney section. Fasteners used to secure chimney sections shall not penetrate  
chimney flue liner. See Part C of Figure 8.  
5. A listed factory-built wall pass-through system may be purchased and installed according to the instructions pack  
aged with it to provide a safe method of passing the chimney connector through a combustible wall for connection  
to a masonry chimney.  
Additional requirements pertaining to Figure 8 and the above wall pass-through systems:  
1. Insulation material used as part of wall pass-through system shall be of noncombustible material and shall have a  
thermal conductivity of 1.0 Btu • in./ft.² • °F (4.88 kg • cal/hr • m² • °C) or less  
2. All clearances and thicknesses are minimums: larger clearances and thickness are acceptable.  
3. A chimney thimble, as shown for 3" and 4" above (Parts C and D respectively of Figure 8) shall be for types "3" and  
4" connections to facilitate removal of the chimney connector for cleaning. The chimney thimble shall be of ASTM  
C315 fireclay with 5/8" minimum wall thickness , or material or equivalent durability. The inside diameter of the  
thimble shall be sized for the proper snug fit of a 6" diameter chimney connector pipe. The thimble shall be installed  
without damage to the chimney flue. The thimble shall extend through the chimney wall to, but not beyond, the  
inner surface of the chimney flue and shall be permanently cemented in place with high temperature cement.  
4. A chimney connector to a masonry chimney, except for 2" above (Part B of Figure 8), shall extend through the wall  
pass-through system to the inner face of the chimney flue, but not beyond. It does not have to be fastened in place  
so long as it cannot accidently be pulled out of the chimney or shoved into the chimney flue. If fasteners are used  
to secure the chimney connector to a masonry chimney, the fasteners shall not penetrate the chimney flue liner.  
5. Any material used to close up any opening for the connector shall be noncombustible.

In addition to the methods shown by A, B, C, and D of Figure 8, a listed factory-built wall pass-through system  
may be purchased and installed according to the instructions packaged with it to provide a safe method of  
passing chimney connector through a combustible wall for a connection to a masonry chimney.  
CONNECTION OF CHIMNEY CONNECTORTO A MASONRY CHIMNEYWHEN CHIMNEY CONNECTOR  
DOES NOT PASSTHROUGH A COMBUSTIBLEWALL  
If the chimney connector does not have to pass through a combustible wall to get to a masonry chimney, simply connect  
the chimney connector directly to the masonry chimney's chimney thimble as described and shown by parts C and D of  
Figure 8. Remember, the chimney connector should extend into the chimney thimble to the innerface of the chimney flue  
but not beyond; if the chimney connector is extended through the chimney thimble into the chimney flue, resistance to the  
flow of smoke and gases up the chimney will occur; that flow resistance will have an adverse affect on the operation and  
performance of the heater and venting system.

SMOTHER A FIRE WHEN ADDING FRESH  
COAL.  
FUEL, Model 1300  
Egg size (1-3/16" or larger) bituminous coal  
for residential furnaces, or any of the specially  
packed fireplace coals can be used. Coal with a  
low ash content (2% to 6%) is recommended.  
FUEL, Model 1400  
Hardwood, 18" to 26" should be split and air dried  
(seasoned) for 6 months.  
LIGHTING  
CAUTION  
DO NOT OPERATE WITH THE FEED AND/OR  
ASH DOOR OPEN. THIS FURNACE IS DE-  
SIGNED FOR THERMOSTATIC OPERATION.  
OPERATION WITH ANY OF THESE DOORS  
OPEN WILL OVERHEAT AND DAMAGE THE  
FURNACE.  
1.  
Set the thermostat on "HIGH" for maximum  
draft.  
2.  
Open the feed door and place paper and  
kindling on the grate for starting the fire.  
Light the fire and close the feed door.  
Add wood or about 15 lbs. of coal (depending  
on which model) after fire is burning briskly.  
Set thermostat for desired temperature.  
"MEDIUM" setting is normally satisfactory.  
Set higher or lower for your comfort.

CAUTION  
NEVER USE GASOLINE, GASOLINE-TYPE  
LANTERN FUEL, KEROSENE, CHARCOAL  
LIGHTER FLUID, OR FLAMMABLE LIQUIDS  
TO START OR "FRESHEN UP" A FIRE IN THE  
FURNACE.  
5.  
ADDING FUEL  
WARNING  
When starting a fire, add small amounts of fuel  
instead of adding large quantities of fuel. This will  
give more complete combustion and less buildup  
of tars or soot in the chimney.  
NEVER STORE FLAMMABLE LIQUIDS, ES-  
PECIALLY GASOLINE, IN THE VICINITY OF  
THE FURNACE.  
ADJUSTING BLOWER LIMIT CONTROL SET-  
TINGS.  
1. Set thermostat to HIGH before opening feed  
door.  
The temperature in the plenum of the warm air  
furnace at which the blower turns on or turns off,  
is controlled by the setting of the pointers in the  
blower limit control. These pointers may be ad-  
justed through their entire range of settings to  
achieve the desired warm air output from furnace.  
(See Fig. 16 below)  
2. Wood fire - Model 1400.  
Add wood to a convenient level.  
3. Coal Fire - Model 1300.  
a. Never smother the fire when adding coal (See  
Caution). Gasaccumulationandamildsmoky  
explosion will occur. Add fresh kindling if the  
bed of coals has cooled.  
b. Addupto20lbs.ofcoalperloading. Neveradd

d. ashes into the ash pan. Do this at least once  
every 12 hours of operation. Empty ash pan  
regularly. Do not allow ashes to buildup to  
grate as grate will warp and burnout, and you  
might spill the ashes when removing the pan.  
Dispose of hot ashes properly (See note 12 on  
page 4).  
Move both pointers towards the right (counter  
clockwise) - this increases the temperature  
setting at which the blower will turn on and off.  
Move both pointers towards the left (clock-  
wise) - this decreases the temperature setting  
at which the blower will turn on and off.  
Move pointers away or apart from each other-  
this increases the time that the blower will run  
on each warm air cycle.

Service Hints  
If the chimney is operating too cool, water  
will condense in the chimney and run back  
into the furnace. Creosote formation will be  
rapid and may block the chimney. Operate  
the furnace at a high enough fire to keep the  
chimney warm, preventing this condensa-  
tion.  
Do not expect a furnace to draw. It is the  
chimney that creates the draft. Smoke spillage  
into the house or excessive buildup of water or  
creosote in the chimney are warnings that the  
chimneyisnotfunctioningproperly. Correctthe  
problembeforeusingfurnace. Possiblecauses  
are:  
4.  
5.  
If the fire burns well, but sometimes smokes  
or burns slowly, it may be caused by the  
chimney top being lower than another part  
of the house or a nearby tree. The wind  
blowing over a house or a tree, falls on top  
of the chimney like water over a dam, beat-  
ingdownthesmoke. Thetopofthechimney  
should 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).  
1. The connector pipe may be pushed into the  
chimney too far, stopping the draft (Fig. 6)  
2. Do not connect two furnaces or a stove and  
furnace into the same chimney flue.  
3. The chimney used for a furnace must not be  
used to ventilate the cellar or basement. If  
there is a cleanout opening at the base of  
the chimney, it must be closed tightly.  
6.  
See page 29 for list of trouble shooting tips.  
A draft reading of .05 to .06 w.c. is suggested for proper burning of this unit when using  
wood or bituminous coal as fuel. When using anthracite coal, this draft reading is a  
minimum reading.  
Chimney Maintenance  
Creosote and Soot - Formation and Need for Removal  
When wood is burned slowly, it produces tar  
and other organic vapors, which combine with  
expelled moisture to form creosote. The creo-  
sote vapors condense in the relatively cool  
chimney flue of a slow-burning fire. As a result,  
creosote residue accumulates on the flue lin-  
ing. When ignited, this creosote makes an  
extremely hot fire.  
If creosote or soot has accumulated, it should  
be removed to reduce the risk of a chimney fire.  
Chimney fires burn very hot. If the chimney  
catches fire, immediately call the fire depart-  
ment, thenreducethefirebyclosingtheinletair  
control. Pour a large quantity of coarse salt,  
baking soda or cool ashes on top of the fire in  
the firebox.  
When coal is burned, the products of combus-  
tion combine with moisture to form a soot resi-  
duewhichaccumulatesonthefluelining. When  
ignited, this soot makes an extremely hot fire.  
CAUTION  
A chimney fire may cause ignition of  
wall studs or rafters which you thought  
were a safe distance from the chimney.  
If you have a chimney fire, have your  
chimney inspected by a qualified per-  
son before using again.  
The chimney should be inspected at least twice  
monthly during the heating season to deter-  
mineifacreosoteorsootbuilduphasoccurred.
