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  
masonryorULListedFactoryBuiltChimneyforresidentialType103HTorBuildingHeating  
ApplianceChimney. Usea6"diameter chimneyorlarger, thatishighenoughtogiveagood  
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"NFPA211. TheaddressoftheNFPAisBatterymarchPark,Quincy,MA02269.  
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  
thoroughlycooled. Theashesmaybeburiedinthegroundorpickedupbyarefusecollector.  
13.CAUTION-Thespecialpaintsusedonyourfurnacemaygiveoffsome smokewhilethey  
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, butitwillnotstandroughhandlingorabuse. Wheninstallingyourfurnace, usecare

HOW THE FURNACE FUNCTIONS  
PARALLEL INSTALLATION: (U.S. ONLY)  
Your Hotblast Furnace is designed to  
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 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  
(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.  
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 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 ther-  
mostat. Whenthetemperaturefallsbelowthe  
setting on the wall thermostat, the forced draft  
will come on (U.S. Stove Option 11/DKU)  
The warm air supply outlet of the Hotblast  
Furnace shall not be connected to the cold air  
returnofthecentralfurnace,becausethepos-  
sibility exists of components of the central  
furnace overheating and causing the central  
furnace to operate other than is intended.  
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.  
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.  
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.

LOCATING THE FURNACE  
1.The furnace should be located in the  
same room as the central system  
and as close as possible, but not  
closer than 9". There should be no  
wall between the furnace and the  
warmairoutletductthatisconnected  
directly to the warm air outlet plenum  
of the central furnace. (See Fig. 2)  
2.  
The unit will require installation with  
the following clearances:

4.  
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  
ascloseasyouwishtothewall. Ifthe  
wall is only faced with brick or stone,  
treat it as a combustible wall.

CHIMNEY CONNECTION  
Fig. 4  
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  
APPLIANCE.  
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.  
Fig. 5  
LISTED FACTORY BUILT CHIMNEY  
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).

RULES FOR CONNECTOR  
PIPE INSTALLATION  
1. The crimped end of the chimney connector fits  
insidethefurnacefluecollar. Installadditional 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 24 gauge and  
al-  
though blued steel is satisfactory, high temp painted  
black is much more desirable.  
2. Slope any horizontal pipe upward toward the  
chimney at least 1/4 inch for each foot of horizontal  
run.  
RIGHT  
WRONG  
WRONG  
3. You must have at least 18 inches of clearance  
between any horizontal piping and the ceiling.  
(See Fig. 3)  
Fig. 6  
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.  
4,5,7)  
Adjusting the Barometric Draft Regula-  
tor  
1. Drill a hole in the chimney connector within 18" of  
the flue collar below the barometric draft regulator  
just large enough for the tube of the manometer.  
2. Build a fire after all chimney connections have  
been made.  
3. Use a manometer to measure the draft in the flue.  
4. Adjust the Barometric Draft Regulator to obtain a  
draftof0.05-0.06"W.C. understablefireconditions.

completed by a  
qualified installer complying with NFPA Standard  
No. 70 and local codes.  
g) Optional Plenum Fan Control Switch (Part No.  
11PCS) is available for installation on the plenum of  
central hot air heating furnace. The purpose of this  
switch is to activate the circulating fan of the central  
hot air heating furnace when the temperature in the  
plenum exceeds 120 degrees F., and shut off the  
fan when the temperature in the plenum is reduced  
to 100 degrees F. This avoids overheating the  
plenum.  
5. Installation for Supplemental Heat Application to  
Existing Central System. (See Fig. 2 for typical  
installation.)  
a) Place Wood or Coal Burning Furnace so that  
the chimney connector will be as short as practical  
and avoiding unnecessary sharp turns in the smoke  
pipe connector and the installation of devices that  
would create excessive resistance to the flow of flue  
gases.  
The electrical supply for operation of this fan  
control switch is to be obtained from the same  
electrical supply as the central hot air heating sys-  
tem. Follow the instructions of the wiring diagram  
(Fig. 11). Do not make connections across the  
thermodisc in the furnace.  
Make electrical wire connections in accordance  
with NFPA Standard No. 70 and local codes in the  
power supply junction box (See Fig. 13). The wiring  
to complete the connections should be 18 AWG  
minimum copper and 90 degrees centigrade in a  
cable.  
b) Locate the Wood or Coal Burning Furnace as  
close as practical to the existing central hot air  
heating system, maintaining clearances as stated  
on the label on the fuel door.

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 build-up 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,  
beating down the smoke. The top of the  
chimney 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 28 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  
creosote vapors condense in the relatively cool  
chimney flue of a slow-burning fire. As a result,  
creosote residue accumulates on the flue  
lining. 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  
de-  
partment, then reduce the fire by closing the  
inlet air 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  
combustion combine with moisture to form a  
soot residue which accumulates on the flue  
lining. 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  
determine if a creosote or soot build up has  
occurred.
