Cleaning the stove interior

Caution: Make sure the stove is cold.

1.  Locate necessary equipment such as: good lighting 

(head lamp), steel scraper / ice scraper, ashtray or 

ash vacuum and preferably a pair of gloves.

2.  Cover the floor and furniture around the stove. For 

items  3 and 4 below, it is an advantage and to have 

two people, since the top plate is heavy.

3.  Tilt the top plate and scrape/vacuum away the 

soot on the underside of the top plate. (Two-piece 

top plate, for top-mounted chimney, the rear plate 

should not be removed for cleaning).

4.  Lift off the top plate.
5.  Scrape off soot on smoke conductor plates and pick 

out the parts. The ash is swept down the stove or 

sucked away eventually.

6.  Pick out steel studs on which horizontal smoke 

conductor plates lie and scrape away the soot from 

the stones.

7.  The ash is now in the bottom of the stove, and is 

removed with ash vacuum, or ash spade/bucket.

8.  Inspect Skamol plates in combustion chamber and 

replace if defective.

9.  Lift the cover over the draft control and inspect 

the draft control. If needed, lubricate the shaft and 

guide pin with copper grease.

10. Replace the steel dowel pins, the smoke guide 

plates, and put the top plate back in place.

When firing with dry wood and with good draft (full 

opening for combustion air while firing) there should 

be very little creosote formation, however we advise 

that you inspect for creosote formation inside the stove 

at the same time when inspecting the chimney.

Cleaning the glass

1.  Remove dust and loose-fitting soot with a dry 

cloth.

2.  Wet a newspaper or paper towel with water, dip 

the wet paper in the box and wipe the soot on the 

glass. Then wipe with a dry clean cloth or paper.

3.  Clean the glass again with glass cleaner.

Do not use abrasive or corrosive products to clean the 

glass. If the stove’s glass is crushed or cracked, the glass 

must be replaced before the stove is used again.

Replacing the glass

Always operate the door slowly and cautiously to avoid 

cracking or breaking the glass. Never use the door 

to push wood into the firebox. If the glass becomes 

cracked or broken follow the following replacement 

procedure:

1.  First loosen and then carefully remove the four 

glass clips from the inside of the door. Remove all 

pieces of the glass panel and gaskets.

2.  Remove all remaining debris from the glass area 

using a wire brush.

3.  Apply a small bead of gasket/stove cement and the 

new gasket. Do not overlap the ends of the gasket 

rope.

4.  Center the new glass panel over the gasket and 

loosely reinstall the glass clips. Tighten the clips, 

alternating at opposite corners. Avoid applying 

uneven pressure on the glass.

5.  It may be necessary to retighten the glass clips after 

the stove has been used again and the gaskets has 

seated.

• 

Before you open the door, place the Air Control

Lever in the full open position.

• 

Always wait a few seconds before opening the door. 

This allows the renewed air circulation to clear 

unburned gases from the firebox. Hold the door 

open just slightly for a couple of seconds before 

opening it fully. This will also help ensure that no 

smoke escapes into the room.

• 

Use a stove tool or poker to distribute the hot 

embers equally around the firebox and push ashes 

into the ash pan.

• 

Load the fuel, usually with smaller logs first.

• 

Close the door and secure the latch, the wood will 

start to burn after a few minutes.

Emptying ashes

Having some of the ashes always in the stove is 

beneficial for the firing. The ashes isolate to the cold 

bottom, leading quicker to high temperatures in the 

burn chamber, and give some space for air to get 

under and at the sides of the wood, thus improving the 

combustion.

After a number of firings it will be necessary to remove 

part of the ashes. Opening the door and simply using 

a suitable tool to dig out ashes can do this. This should 

not be done before the stove is completely cooled 

down! Wait at least 12 hours after the last firing before 

doing so. The ashes should be put in a bucket of 

incombustible material, such as an iron bucket.

After firing with wood, a relatively small amount of ash 

occurs. This ash bed is a good insulator and provides 

better combustion. Therefore, leave a thin ash layer on 

the bottom of the oven.

Regularly remove the excess ash. 

Use an ash spade and fill the ash in a suitable ashtray 

which is then emptied at a fire-proof location, it is 

recommended that ash discharge be done at least 12 

hours after firing is finished.

Only use a container of noncombustible material, like 

iron, to put the ashes into. Put a lock on the container 

until all ashes, coals and cinders, are thoroughly 

cooled.

Exterior cleaning

The stone can be washed easily with ordinary 

household detergent. Stains of soot and soot water are 

removed by brushing lightly with fine sandpaper (180).

Creosote Formation and the Need for Removal

When wood is burned slowly, it produces tar and 

other vapors that combine with moisture to form 

creosote. Creosote vapors condense in the relatively 

cool chimney flue, and creosote residue accumulates 

on the flue lining. When ignited, this creosote fuels an 

extremely hot fire.

The chimney connector and chimney flue should be 

inspected at least every two months during the heating 

season to determine if creosote buildup has occurred.

If creosote has accumulated, it should be removed 

to reduce the chance of a chimney fire. A qualified 

chimney sweep or other authorized service person can 

provide this service.

It is also important to remember that chimney size, 

temperature and height all affect draft which in 

turn affects the formation of creosote. An exterior 

chimney, whether masonry or prefabricated steel, 

will be exposed to cold outside temperatures, 

and consequently, will be more prone to creosote 

accumulation than an interior flue.

Creosote may also form inside the stove, at the top in 

the highest section. This happens since the flue gas 

temperature can be quite low, leading to condensation 

and the formation of some creosote on the inside 

of the stove at the stone surfaces. Creosote has an 

insulating effect, so it’s important that the stove interior 

be cleaned annually.
