Cleaning & maintenance of wood burning stoves

Do Morsø wood-burning stoves rust?

If looked after and installed properly, the stove will not rust. If rust appears on the stove, it is usually because the stove has been exposed to moisture, possibly from the chimney. In summerhouses, the temperature is often very cold in winter and the still air in the combustion chamber can cause condensation on the stove surface. You should therefore leave the valves in the stove open to prevent condensation forming on the oven, which can cause rust. Another good idea is to leave the door ajar when the stove is not being used for a period of time.

The glass in my stove has cracked. What has happened and can I replace it myself?

Cracks on the glass may happen due to bumps from the wood. Besides, impurities may be found in the wood such as pebbles that may hit the glass during the combustion. If the glass has cracked, it naturally has to be replaced. Replacing the glass yourself is a fairly simple job. If you’re unsure about your ability or would prefer, talk to your local Morsø Dealer. Morsø has the necessary adhesive fibre for glass that can be bought at any Morsø dealer.

The glass in my stove is covered in soot. what could be wrong?

You can clean the glass using Morsø Glass Cleanser. This must be done when the stove is cold. If heavy soot build-ups appear, use treble ammonia water to clean the glass. Soot may appear on the glass if the combustion temperature is too low or if the air controls are used incorrectly. The secondary air controls must be open and the primary air controls closed. The primary air either from the riddling grate or air control are only to be used during the lighting period or when dry wood is put into the stove. Morsø recommends a moisture content in the wood of 16-20%. If you wan to be sure that wood is dry enough, a moisture meter can be purchased from your local Morsø Dealer.

How do I remove scratches and marks?

If there are marks on the stove or it simply needs painting to freshen it up, you must clean the surface first. Rust can be removed using fine steel wool, then painted using Morsø Senotherm spray paint (for black Morsø stoves use coke spray). Please note that MORSO stoves are dark grey in colour not black.

The sealing rope in the door is loose, or has come away. What do I do?

The sealing rope in the door becomes worn after it has been in use for some time, and can start coming away.
The seal is fitted using Morsø ceramic adhesive.

When replacing the seal, the surface must be cleaned thoroughly with steel wool or a steel brush. Seal kits with adhesive can be bought from your local Morsø Dealer. Ensure you use MORSO sealing rope.

How do I remove dirt from the door glass?

The glass can be cleaned by using an approved glass cleaner. Alternatively warm soapy water and newspaper can be used but only when the stove is cold.

How often should the stove be cleaned for soot and ashes?

The stove needs to be cleaned and serviced fully at least once a year. But naturally depending on how much the stove is used. The baffle is removed from the stove and cleaned up – using a nozzle or a Ash Cleaner. A Ash Cleaner is also suitable for cleaning the rest of the stove. Note that the stove must be cold when cleaned. Soot may appear on the glass if the combustion temperature is too low or if the air controls are used incorrectly. The secondary air controls must be open and the primary air controls closed. The primary air either from the riddling grate or air control are only to be used during the lighting period or when dry wood is put into the stove. Morsø recommends a moisture content in the wood of 16-20%. If you wan to be sure that wood is dry enough, a moisture meter can be purchased from your local Morsø Dealer.

Can I use stove blacking on Morsø stoves?

No, do not use stove blacking on Morsø stoves.

Stove blacking cannot stick to enamelled Morsø stoves; the surface becomes blotched and may flake when the stove is heated.The surface of painted stoves will also become discoloured and blotched if you use stove blacking. Stove blacking should only be used on old stoves that have been ground or sandblasted.

Painted stoves must be painted with Morsø Senotherm paint, and enamelled stoves only have to be washed with hot, distilled water and brown soap.
