INTRODUCTION
This manual provides installation, operation, maintenance
instructions and parts ordering information for the Big Jack
Model BJ90 and the Super Jack Model SJ125 wood burning
furnaces.
IMPORTANT
Please read all instructions carefully before attempting
installation of this unit. Installation should only be done
by a qualified installer.
UNPACKING AND INSPECTION
Inspect the furnace for visible damage. The furnace is
shipped in one carton.
Inside the wood loading door is another carton. It contains a
gasket, conduit clip, wiring harness, fan and limit control,
transformer-relay, combustion blower and barometric draft
control.
A circulating blower, if ordered, is shipped in a separate car-
ton.
RULES FOR SAFE INSTALLATION AND OPERATION
1. Read these rules and the instructions carefully. Failure
to follow these rules and instructions could cause a
malfunction of the furnace. This could result in death,
serious bodily injury and/or property damage.
2. Check your local codes. The installation must com-
ply with them.
3. Use only the type of fuel approved for this furnace.
Over-firing will result in failure of heat exchanger and
cause dangerous operation.
4. You must have a sufficient supply of combustion air to
the area in which the furnace is located. (page 12)
5. Factory Built Chimneys: Connect this furnace to a
chimney that complies with NFPA 211 3-1.2. Factory
built chimneys for use with wood-burning appliances
shall comply with the HT requirements of UL 103 or
CAN/ULC-S629-M87. This means you must install
what is referred to as type HT all fuel chimney.
Masonry Chimneys: Connect this furnace to a chim-
ney that complies with NFPA 211 3-1.2. A field con-
structed chimney of solid masonry units, bricks,
stones, listed masonry chimney units, or reinforced
Portland cement concrete that is lined with suitable
chimney flue liners and built in accordance with the
provisions of Chapter 4 of this standard.
6. Follow a regular service and maintenance schedule
for efficient and safe operation.
7. Before servicing, allow furnace to cool. Always shut off
electricity and fuel to furnace when working on it. This
will prevent electrical shocks or burns.
LOCATING THE FURNACE
Locate the furnace as close to the chimney or flue as possi-
ble and near the center of the heat distribution system or
next to primary furnace if used.
Locate furnace where there is sufficient air supply for venti-
lation and proper combustion to comply with the minimum
clearances required for fire protection and accessibility. See
page 7 for typical installations. See also Combustion Air.
(page 12)
NOTE
It is recommended that a 2", noncombustible raised pad
be used for the furnace. This will prevent moisture from
getting under the furnace and causing corrosion.
PLACEMENT AND MINIMUM CLEARANCES
For installation of our Jack Line furnace, the National Fire
Protection Association (NFPA) Standard 90B specifies the mini-
mum standard clearances to combustible surfaces as summarized
below.
CLEARANCE CHART
Above Top of Plenum 18”
From the Front 48”
From Sides and Back 18”
From Flue Pipe 18”
From Existing Furnace 6”
From Horizontal Warm Air Duct:
Within 3 ft. of Plenum 18”
Within 3 to 6 ft. Plenum 6”
Beyond 6 ft. of Plenum 1”
All heat runs 1”
PARTS ASSEMBLY
1. Install the combustion blower & gasket to the provided
opening just below the wood-loading door on the front
of the furnace.
2. Attach the 4x4 junction box with the transformer/relay
to the mount provided at the top right hand side of the
front of the furnace.
3. Insert the fan-limit control into the sheet metal plenum
approximately 6 inches above the furnace.
4. Wire according to the enclosed wiring instructions &
local codes. (See page 13)
REDUCED CLEARANCES
Up to 50% less clearance between combustible walls and chimney
connector to furnace and ducts is allowed if insulated according to
NFPA Standard 90B or your local building code. This copyrighted
book is available from the National Fire Protection Association Inc.

It is a mistake to assume that sheet metal, masonry, or asbestos-
like board placed directly against a wall protects it. Materials
installed in this manner give very little protection. These materials
are good conductors, so they will be almost as hot on their back-
side as well as on their exposed side. Therefore, the combustible
wall behind it is still a fire hazard.
CAUTION
Do not use any smoke pipes less than 24 gauge between
furnace and chimney.
CONNECTING SMOKE PIPE
Set the smoke pipe end of the furnace as close to the chimney as
possible. For every foot of lateral pipe, the rise of the smoke pipe
toward the chimney must be at least one inch. Do not exceed 10
feet in length. A cleanout tee should be installed for removal of
soot and fly ash.
Do not install the smoke pipe longer than necessary to reach the
chimney for purposes of trapping heat. The smoke outlet temper-
ature is designed so that the heat emitted is needed to carry the
by-products of combustion out through the chimney.
The smoke pipe must not pass through any combustible material.
The smoke pipe entrance into a masonry chimney should be at
least 2 feet above the cleanout. The smoke pipe must not extend
into the chimney beyond the inner face of the chimney liner.
WARNING
Check your chimney. The chimney is a very important part of
your heating system. It must be the right size, properly con-
structed and in good condition. No furnace can function prop-
erly with a bad chimney. The chimney must supply a draft of
.03 Water Column. If possible, use a 15 foot or higher chim-
ney. Add an additional foot to the chimney for each 1,000 feet
of elevation above sea level.
PROPER CHIMNEYS
The National Fire Protection Association (NFPA) requires that all
factory built chimneys be Listed and installed in accordance with
conditions of the Listing in the manufacturers instructions. NFPA
also requires that your chimney extend at least three (3) feet
above the highest point when it passes through the roof and at
least two (2) feet higher than any portion of the building within ten
(10) feet of the chimney.
Factory built chimneys must be what NFPA refers to NFPA 211 1-
5.217.4 as Type HT. HT is an abbreviation meaning High
Temperature.
Masonry Chimneys as referred to in NFPA 211 1-5.2.17.6, a field
constructed chimney of solid masonry units, bricks, stones, listed
masonry chimney units, or reinforced concrete that is lined with
suitable chimney flue liners and built with the provisions of Chapter
4 of this standard.
DO NOT CONNECT THIS FURNACE TO A
CHIMNEY SERVING ANOTHER APPLIANCE
WARNING
Return air MUST NOT be drawn from inside the room
where the furnace is located.
FURNACE CASING
1. The furnace is shipped unassembled in a carton attached to
the furnace.
2. Insert the left and right side panels into the slots at the base
of the furnace.
3. Place top panel over the front edge of the furnace and then
into the side panels.

MOUNTING THERMOSTAT & SUB-BASE
Thermostat must be mounted on an interiior, centrally located wall
away from direct sunlight and drafts and approximately 5 feet
above the floor.
INSTALLATION
Important: Make these adjustments when installing.
VERTICAL FLUE:
1. Adjustment weight must be in RIGHT HAND SLOT
(marked "V") in bracket on gate.
2. The arrow on flap at bottom of gate must line up with let-
ter "V" on lower right part of gate. If it does not, remove
flap, turn over and snap onto gate again.
Flap can be removed by inserting small screwdriver at the back
side of the gate between the gate and the flap, then pulling
downward on flap.
HORIZONTAL FLUE:
1. Adjustment weight must be in LEFT HAND SLOT
(marked "H") in bracket on gate.
2. The arrow on flap at bottom of gate must line up with let-
ter "H" on lower left part of gate. If it does not, remove
flap, turn over and snap onto gate again.
Bend outward the two ears at the front corners of collar and insert
clamping screw. Bolt the remainder of the collar together. See Fig-
ure 2. Hold the collar against the flue in the EXACT position and
mark the outline of the collar on the flue. Cut a hole in the flue
about half an inch smaller than the marks.
Then cut a series of short slits (about 3/8" or 1/2" deep) around
the edges of the opening. After the collar is strapped on the flue
the cut edges can be bent outward into the collar and thus make
a better joint. WHEN FINISHED, THE OPENING INTO THE FLUE
MUST BE EQUAL IN SIZE TO THE COLLAR OF THE DRAFT
CONTROL. If flue pipe is made of material too heavy to bend out
into the collar, the opening into the flue must be within 1/4" of the
same diameter as the collar.
Strap the collar to the flue pipe and place the draft control into the
collar, fastening it there by tightening the clamping screw in the
collar.
Use a spirit level to make sure that the control does not lean for -
ward or backward but instead is plumb in both directions, regard-
less of whether the flue is horizontal, vertical or sloping.
INITIAL SETTING OF BAROMETRIC CONTROL
Set the control at a maximum of .03 or as low a draft as will give
good combustion and meet the requirements for heat. Turn
adjustment weight counter-clockwise to loosen, then slide in slot to
proper position and tighten. Bracket is marked 2, 4, 6, and 8, which
indicates draft settings of .02, .04, etc. (These are drafts in flue
adjacent to control, not over-fire drafts.)

BAROMETRIC DRAFT CONTROLS
CHOOSING THE LOCATION
Do not attach draft control to top or bottom of flue
pipe, nor in a room separated from appliance.
Best location is as close to appliances as possible.
