CONTROL AND COMPONENT FUNCTIONS

AUGER The auger transfers the pellet fuel from the hopper end of the burner tube down
and into the fire pot.

AUGER MOTOR The auger drive motor turns the auger.
BURNER TUBE The burner tube contains two passageways, one for the auger tube and the

other for combustion air. This tube supplies both the fuel and combustion air to the fire pot.
BLOWER The blower forces return air over the furnace heat exchanger and into the home’s

duct system. The blower is controlled by the fan limit control.
CUP MOTOR The cup drive motor turns the cup which dispenses fuel from the pellet hopper

to the auger.
DRAFT INDUCER The draft inducer takes combustion air, forces it down the burner tube

and into the fire pot where combustion occurs. The flame can be adjusted by regulating
the damper on the draft inducer.

FAN LIMIT CONTROL The fan limit control automatically activates the blower on
temperature rise, and disengages on temperature fall. Normally, this control is set to bring
the blower on at 140°F and then turn off at 100°F. The fan limit control also features a
200°F limit, where if the temperature for whatever reason may climb to 200°F this control
cuts power to burner, but keeps the blower running to cool the heat exchanger. NOTE: IF

YOU ARE REPLACING THE FAN LIMIT CONTROL, MAKE SURE THE BRASS
CONNECTOR IN THE MIDDLE IS SNIPPED OR REMOVED, IF IT IS NOT IT WILL RUN
CONTINUOUSLY.

FIREPOT The fire pot is where combustion occurs. Pellets are delivered into the fire pot by
the auger. The heat of the fire in the fire pot causes gases to oxidize off the pellets, and as
the combustion air mixes with these gases, they burn with a flame similar to that of an oil
or gas fire.

HOPPER The hopper is where the pellets are stored and then funnelled down to feed the
cup.

SAFETY DISC The safety disc interacts with the burner for positive flame protection to
guard against misfires and to shut down the burner in the event of the fuel hopper running
dry. If the burner loses its flame potential, misfires, or runs out of fuel, the safety disc will
drop out, locking out the burner.

BURNER LIMIT If the unit should ever burn back into the burner tube, the 200°F limit will
open the circuit, shutting the entire burner down. The burner will not start until it is
manually reset. If this should happen, locate the cause before resetting limit and relighting
unit.

GENERAL INSTRUCTIONS

1. Installation is allowed only by a licensed, bonded heating contractor.

2. Install this furnace in accordance with local mechanical codes and regulations.

3. Consult manual “J” of the air conditioning contractors Association (ACCA) or air 230
to estimate heating requirements.

4. Always install this furnace with adequate return and supply duct systems.

5. The installer must explain in detail, the operations of this furnace to owner/operator,
including minor service requirements.

6. Never block or restrict any air intake ports. Dangerous overheating can result.

7. Install this furnace with safe clearances to combustible surfaces.

8. Connect this furnace to its own independent Class L Chimney at least 4 inches in
diameter.

9. This is a good furnace, but it cannot make up for a poor or incorrect installation.

10. Repair should be done only by a qualified service person.

11. Never stack or pile combustible materials against the furnace.

12. Never use, store or dispose of flammable liquids near the furnace.

13. Always have a smoke or ionization detector installed in your home.

14. Disclaimer notice: No guarantee is made regarding the heating capacity of this

unit. The actual area that this unit will heat depends on factors such as conditions of
the building, heat loss, type of construction, the amount of insulation, type of air
movement, and the location of the furnace.

15. The manufacturer accepts no responsibility for improper installation of this

pellet/corn furnace or improper use or negligence of any kind with continued use of
the furnace.

16. The manufacturer recommends fuelling this furnace with premium wood based

pelletized fuel with moisture content between 2 – 8% or clean-shelled corn with a
moisture content less than 15%. Do not attempt to burn higher moisture content or
burn lesser grade fuels. Any questions regarding pellet fuel can be answered at the
Pellet Fuels Institute website, www.pelletheat.org.

17. If this furnace runs out of fuel, or misfires, it will automatically shut-off. If this

occurs, you must manually re-light the corn unit, repeating steps 8 – 14 in the start
up instructions on page 15. Re-light the pellet unit according to operating
instructions on page 14.

18. Do not operate this furnace with door open.

19. Doors and heat exchanger surfaces of the furnace are hot during operation.

touch with bare hands, or allow children to play near the furnace unattended.

20. Do not allow anyone to operate the furnace that is not familiar with its operation.

21. Manually place fuel in the fire pot

could result.

22. After lighting, make sure the main fire door and ash door are closed and sealed

tight.

23. Set combustion air damper at not less than 50%. Damper settings will vary widely

depending on draft characteristics of your chimney system. The unit should emit no
visible smoke from the exhaust, if it does, open the damper slide until smoke is
gone. Draft characteristics should be between .04 and .08 inches water.

CHIMNEY AND VENTING

Chimney required for the GBU070 is 4” Class “L” (also known as PL vent). A
starting collar must be used to attach the venting system to the furnace. When
connecting into a Class “A” or masonry chimney an approved 4” liner MUST be
used to prevent back drafting of the chimney.

EXISTING CLASS “A” CHIMNEY:

Run 4” Class “L” connector from the furnace connection to a positive
connection with the class “A” chimney. AN APPROVED 4” LINER MUST
BE USED IN CLASS “A” CHIMNEYS. Make sure each joint is firmly
locked in place. Make sure the attachment of Class “L” to the Class “A”
chimney is secure with sheet metal screws. Seal all joints with high
temperature silicone. Class “L” connector should maintain a pitch on
rise from the furnace to the chimney of at least ¼” per foot.
A): “L” Vent connector 4” B): “L” Vent elbow 90° adj. 4”

EXISTING MASONRY CHIMNEY: Run 4” Class “L” connector from
the furnace connection to a positive connection with the masonry
chimney. Make sure each joint is firmly locked in place. Make sure
the penetration of the Class “L” connector into the masonry chimney
is sound and secured with high temperature cement. Seal all joints with
high temperature silicone. Class “L” connector should maintain a pitch
on rise from the furnace to the chimney of at least ¼” per foot.
AN APPROVED 4” LINER MUST BE USED IN MASONRY CHIMNEYS.
Your new furnace is so efficient; an unlined chimney could remain
cold and cause a downward pressure creating poor burning,
incomplete combustion or back draft.

__________________________________________________________________________

NEW VERTICAL INSTALLATIONS: Install 4” Class “L” chimney add
accessories according to manufacturers instructions and local codes
(3” clearance to combustibles). Run Class “L” chimney all the way from
the furnace connection to point of termination. Make sure each joint is
firmly locked in place. Seal all joints with high temperature silicone.
Class “L” connector should maintain a pitch on rise from the furnace to
the chimney of at least ¼” per foot.

VERTICAL CHIMNEY’S

The chimney that this unit is connected to (Class “L”, all fuel or masonry) should extend
above the roofline of adjacent buildings to prevent downdraft situations.

1. Class “L” connectors shall be installed without any downward pitch from the

appliances and without any dips or sags.

2. Class “L” connectors shall be pitched upward from the appliance at least ¼” per foot.

3. Class “L” starter adapter shall be firmly attached to the vent outlet collar of the

furnace and a positive seal made with high temp silicone, approved metal tape
and/or sheet metal screws.

4. The chimney shall extend at least three (3) feet above the highest point when they

pass through the roof of the building and at least two (2) feet higher than any
portion of any building within ten (10) feet.

HIGH BUILDING OR
SECTION OF BUILDING

COMBUSTION AIR:
Furnaces must have air (oxygen) for proper performance. The incomplete combustion that

takes place when a furnace is “air starved” causes carbon monoxide (CO) to be formed in
quantities that can be dangerous inside a well-sealed house. Having a source of combustion
air from outside prevents this “air starvation” of the furnace. Provisions for combustion air
shall be made in accordance with applicable provisions of local building codes. The GBU070
combustion air intake is the slot on the back of the unit. Keep this opening free of
obstructions which would restrict airflow.
