•  The furnace is designed to burn air dried wood and 

coal at a predetermined 

fi

 ring rate. Over 

fi

 ring  could 

result in damage to the heat exchanger and cause 
dangerous operation. Over 

fi

 ring occurs when the ash 

door is left open during operation or a highly volatile 
fuel, i.e. large amounts of small kindling, is used. If any 
portion of the connector pipe glows orange or red, you 
are in an over-

fi

 ring situation. Close all dampers.

•  When tending the 

fi

 rebox always pull the baf

fl

 e  slide 

rod out prior to opening load door. Open load door 
slowly to avoid a “

fl

 ash back”. After closing load door, 

push the baf

fl

 e slide rod to the rear.

•  Equip your home with 

fi

 re extinguishers and smoke 

detectors appropriately located.

• Inspect 

air 

fi

 lters regularly. The air 

fi

 lter in the 

fi

 lter box 

should be changed at least every 30 days.

Oil motor on forced air draft every 90 days with a few 
drops o

f 30 wt. oil.

The distribution blower motors may be one of two types. If 
the motor has sealed bearings, no oiling is required.
If the motor is equipped with 

fi

 ll holes, the motor should be 

oiled every 90 days with several drops of 30 wt. oil.
Check the 

fi

 t on the load door. It must 

fi

 t tightly. If it does 

not, check for deterioration or wear of the ceramic rope 
seal. Replace defective seals.
Inspect and clean your chimney and stove pipe regularly.
In event of chimney 

fi

 re, shut all draft controls and call your 

fi

 re department immediately. Alert everyone in the house. 

If the 

fi

 re is still burning vigorously, throw baking soda into 

fi

 rebox or discharge a 

fi

 re extinguisher into the 

fi

 rebox. 

After chimney 

fi

 re is over, completely inspect system for 

damage before further use.
NEVER throw water on the 

fi

 re or at the furnace, as rapidly 

expanding steam could result in a severe scalding.
• Slow 

fi

 res: It is not recommended burning the fur-

nace any more than necessary early in the fall and 
late spring, as you cannot keep the 

fi

 rebox hot enough 

(without overheating your home) to burn gases. Slow 

fi

 res can cause excessive creosote build-up in smoke 

pipe, chimney and 

fi

 rebox.

•  Wood should be placed directly onto the cast iron 

shaker grate of the furnace. Do not use additional 
grates and/or irons.

•  In the event of a power failure, you may operate the 

furnace, provided the following instructions are fol-
lowed:

1. Any 

air 

fi

 lter should be removed.

2.  Observe the furnace operation closely and often till 

power is restored.

•  Do not burn garbage, plastics, gasoline, drain oil or 

other 

fl

 ammable liquids. Plastics, when burned, form 

hydro

fl

 uoric and hydrochloric acids which will damage 

and destroy your furnace pipe and chimney. The burn-
ing of trash or oil can result in an extremely hot 

fi

 re 

and is sometimes a cause of chimney 

fi

 res.  NEVER 

BURN GREEN WOOD OR TIRES.

• 

Do not store fuel or other combustible material within 
marked installation clearances.

NOTE: For further information on using your furnace 
safely, obtain a copy of the National Fire Protection Asso-
ciation publication “Using Coal and Wood Stoves Safely.”

TAMPER WARNING

This wood heater has a manufacturer-set minimum low 
burn rate that must not be altered. It is against federal reg-
ulations to alter this setting or otherwise operate this wood 
heater in a manner inconsistent with operating instructions 
in this manual.

VISIBLE SMOKE

The amount of visible smoke being produced can be an ef-
fective method of determining how ef

fi

 ciently the combus-

tion process is taking place at the given settings. Visible 
smoke consist of unburned fuel and moisture leaving your 
stove. Learn to adjust the air settings of your speci

fi

 c unit 

to produce the smallest amount of visible smoke. Wood 
that has not been seasoned properly and has a high wood 
moisture content will produce excess visible smoke and 
burn poorly.Use the included moisture meter to insure your 
wood has a 20% or less moisture content.

EFFICIENCY

Ef

fi

 ciencies can be based on either the lower heating val-

ue (LHV) or the higher heating value (HHV) of the fuel. 
The lower heating value is when water leaves the com-
bustion process as a vapor, in the case of woodstoves the 
moisture in the wood being burned leaves the stove as a 
vapor. The higher heating value is when water leaves the 
combustion process completely condensed. In the case 
of woodstoves this would assume the exhaust gases are 
room temperature when leaving the system, and therefore 
calculations using this heating value consider the heat go-
ing up the chimney as lost energy. Therefore, ef

fi

 ciency 

ATTENTION:

This wood heater needs periodic inspection and repair for proper operation. It is against federal regulations to operate this 

wood heater in a manner inconsistent with operating instructions in this manual.
