NORMAL CARE & MAINTENANCE

CLEANING THE GLASS

When the fire is first started, it will produce some smoke.
The smoke might accumulate on the glass surface. Before
the fire gets hot, open the door and wipe the glass surface
off with a damp rag.

If after constant use, the glass might fill with ash deposits.
You must clean the glass after the glass has cooled down.
Do not touch the surface with your hands. Take a damp rag
and wipe the glass clean. If this does not clean the glass
use any non-abrasive liquid spray.

DISPOSAL OF ASHES

Ashes should be placed in a metal container with a
tight fitting lid. The closed container of ashes should
be placed on a noncombustible floor or on the ground,
well away from all combustible materials, pending final
disposal. If the ashes are disposed of by burial in soil
or otherwise locally dispersed, they should be retained
in the closed container until all cinders have been
thoroughly cooled.

REMOVAL OF CERAMIC GLASS

Open the door and lift off of hinges. If the door is tight, tap
gently on the bottom of the door with your hand or rubber
hammer. Lay door down on newspaper with glass clips
facing you. Loosen the screws and take off the glass clips.
Remove the broken glass carefully and discard.

Reverse the above procedure for replacing new glass with
new gasket.

CAUTION

DO NOT OPERATE STOVE WITH BROKEN GLASS.

DO NOT SLAM THE DOOR SHUT.

DO NOT STRIKE GLASS.

DO NOT USE ABRASIVE CLEANERS.

DO NOT CLEAN HOT GLASS.

THE CLINKER WILL REMAIN HOT FOR SEVERAL
MINUTES AFTER IT IS PULLED OUT OF THE BURNER
POT.

FUEL POT REMAINS

The “clinker” is the solid mass that remains unburned in
the burner pot. It contains the inorganic parts of the fuel
and is safe to use as fertilizer or dispose of in a proper
container.

SOOT AND FLY ASH

The products of combustion will contain small particles of fly
ash. The fly ash and soot will collect in the exhaust venting
system and restrict the flow of flue gasses. Incomplete
combustion, such as occurs during startup, shutdown, or
incorrect operation of the parlor stove will lead to some soot
formation which will collect in the exhaust venting system.
The exhaust venting system should be inspected at least
once per month (during heavy use) to determine if cleaning
is necessary. Corn has a high ash content.

DAILY MAINTENANCE

• Surfaces on the front of the stove will be extremely
hot during operation. Always wear heat resistant

gloves to perform periodic maintenance.

• Remove heat shield. Using a wooden stick, tap the side
heat exchangers that are located on the left and right
sides of the firebox. When you open the door, they are
located directly inside to the left and right. When you
tap the sides with the wooden stick the loose fly ash will
drop out of these holes.

• Inspect inside stove for excessive ash build up. You will
learn some fuels produce more ash than others.

WEEKLY MAINTENANCE

• Remove the ash pan and dump the ash into a metal
container.

• Cleaning of the exhaust system will depend upon the
ash and debris content of your fuel. If your fuel has
a high ash content and/or significant debris in it, the
exhaust system will require weekly cleaning. Cleaner
fuels will allow for monthly cleaning of the exhaust
system. Remove the exhaust pipe from the back of the
stove and remove any ash that may have collected in
the pipes. Replace the pipes to the stove and seal with
high temperature seal tape. If you have installed proper
clean out tees you will not have to take the chimney
sections apart.

NOTE: A clean unit bums efficiently and will remain

trouble free!

WARNING

WHEN PERFORMING ANY INTERNAL ELECTRICAL
MAINTENANCE

• MOVING PARTS INSIDE OF THE CABINET MAY
CAUSE INJURY. DO NOT OPERATE UNIT WITH
PANELS REMOVED OR OPEN.

• HOT PARTS. DO NOT OPERATE THE UNIT WITH
PANEL OPEN.

• RISK OF ELECTRIC SHOCK. DISCONNECT POWER
BEFORE SERVICING UNIT.

• IN THE EVENT OF COMPONENT FAILURE, REPLACE
WITH THE ORIGINAL FACTORY EQUIPMENT.

CAUTION

TH I S IS A MINIMUM RE QUIREM E NT FOR SOOT
AND FLY ASH REMOVA L . ASHES SH O U L D B E
PLACED IN A METAL CONTAINER WITH A TIGHT
FITTING LID. THE CONTAINER SHOULD BE PLACED
ON A NON-C OMBU S TIBL E FLOOR , WEL L AWAY
FROM COMBUSTIBLE MATERIALS, PENDING FINAL
DISPOSAL. IF ASHES ARE DISPOSED OF BY BURIAL
IN SOIL OR OTHERWISE LOCALLY DISPERSED, THEY
SHOULD BE RETAINED IN THE CLOSED CONTAINER
UNTIL ALL CINDERS ARE NO LONGER WARM.

SEASONAL CLEANING

Once every year you must clean out all of the fuel in the
hopper, firebox area, ash pan and fire pot area. Corn and
any ash can accumulate moisture over the summer months
causing the unit to rust and the fuel to mold.

It is recommended that prior to shutting down the unit in
the spring it is run on the high setting for about six hours to
help clean out the heat exchanger system, venting system
and firebox area.

When the unit is cleaned out, empty the hopper, take the
venting apart and clean out the fly ash, rinse and let dry.
Take the draft blower off and clean out all areas such as
back heat exchanger and lubricate the auger, auger tube,
and fire pot area. (Something like vegetable spray works
great to coat the inside of the unit and the moving parts).
Clean the glass, doors and outer cabinet so that you are
ready for the next heating season. Use of a wet/dry vacuum
makes the clean out easier and faster.
