CLEANING AND MAINTENANCE

IMPORTANT CAUTIONS:

• UNPLUG POWER CORD AND ENSURE APPLIANCE IS COLD

BEFORE PERFORMING ANY MAINTENANCE WORK.

• Some brands of pellets produce more ash and clinkers than

others. Therefore the frequency of performing the following

cleaning procedures depends to a great degree on the quality

of the pellets burned.

• Not cleaning this unit will cause it to burn poorly and will

void your warranty for this appliance.

• When removing ash build-up, use an approved ash vacuum

only. A cleaning brush can be used to loosen any ash build-up

before vacuuming. DO NOT USE A STANDARD HOUSEHOLD

VACUUM OR “SHOP VAC” AS THE FILTERS WILL LEAK THE

FINE PARTICLES OF ASH INTO THE HOME.

Required Cleaning Schedule After Number Of Bags Burned:

Burn-Pot = 10 bags

Ash Drawer = 50 bags

Flue passageways = 50 bags

Combustion Blower = 100 bags

Blower = 100 bags

Notes

• Cleaning schedule will vary depending on quality of pellets used.

Burning high ash pellets will require more frequent cleaning.

• Using a drop cloth is recommended as some ash may spill onto the

ﬂoor during the cleaning process

Burn-Pot Cleaning

The combustion blower comes on at high speed once an hour to blow the

by-products of combustion out of the Burn-Pot. However, the Burn-Pot

should be cleaned more thoroughly after burning about 10 bags of pellets.

The Burn-Pot has a number of holes in the bottom and sides that provide

combustion air to the pellets. The extreme temperatures in the Burn-Pot

can cause the impurities in the pellets to form ash and clinkers. When

the stove is cool, open the front door and lift out the cast iron Burn-Pot.

Scrape the inner bottom and sides of the pot with a screwdriver to remove

all ash and clinkers from these surfaces. Make sure all the holes in the

pot are open. Place the Burn-Pot in the hole from which it was removed.

Make sure the high side of the pot is rotated toward the front of the stove

(see Figure 43). Push the Burn-Pot down so surface A is tight against

the steel supporting the pot. Do not substitute any other grate or pot for

use in this stove.

Cleaning Glass

CAUTION: Do not open the front door when the stove is hot.

To open the door, follow the ﬁrst two steps listed in Front Door

Removal (see Page 24). Clean the glass using a soft cloth or

paper towel and household glass cleaner or wood stove window

cleaner. A damp cloth with a small amount of ash from the

ﬁrebox can also be used to clean the glass.

Ash Drawer Removal and Cleaning

CAUTION: Do not remove the ash drawer when the stove is hot.

To remove the ash drawer, swing open the left and right side

doors. Rotate the lever on latch B (see Figure 44) out from the

stove to release the ash drawer. Do the same with the latch

on the right side of the stove. Pull the ash drawer forward and

away from the stove.

CAUTION: Disposal of Ashes - Ashes should be placed in a

metal container with a tight ﬁtting lid. The closed container

should be placed on a non-combustible ﬂoor or 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.

Reinstall the ash drawer by inserting the drawer in the stove and refas-

tening the left and right latches securely. Note that if the ash drawer

does not seal tightly to the stove, the control board may detect a leak

and shut the stove down.
