How to clean a pellet stove

A few tricks to do it in an efficient and quick way

Pellet stove cleaning is a very simple operation, that really take only few minutes. Since combustion is more regulated than in wood-burning stoves, the ash created is very little, and even less when certified pellets are used. Moreover, some products, such as those that MCZ Group will present at the forthcoming Fair “Progetto Fuoco” in Verona, are equipped with a self-cleaning brazier, which will make life even easier. It is useful especially when for a daily large use of pellets daily, as happens with hydro stoves or or pellet boilers. It works with a mechanical scraping system, that is activated automatically at regular intervals.

Beyond these technological innovations, cleaning operations that have to be done are basically the followings.


1. How to clean the inside of the stove

Cleaning the stove's firebox is an operation that should be performed more or less every 1-2 days. The frequency of cleaning depends on the type of pellets you use (if it is certified it burns better and leaves less residues) and on the hours of operation of the stove. Cleaning the brazier is important to assure proper air flow into the combustion chamber and thus assure flawless operation of the product. A normal vacuum cleaner or - better - a canister vacuum is usually enough to remove the ash. If there is scaling, the brazier must be removed from its seat and all the holes and the grate must be thoroughly cleaned.


2. How to clean the stove glass

Cleaning the glass is important, not just for proper operation, but rather to have a clear and fine view of the flame. If the pellets are good quality and installation was performed correctly, only a little ash is deposited on the glass, which is easily removed with a dry paintbrush. When scaling occurs, you may use a neutral glass spray that contains no abrasives. However, it should be used in small amounts and must not be sprayed on the stove's painted parts nor on the ceramic fibre seal of the fire door, parts which might be easily damaged.


3. Contact a technician for the obligatory annual servicing

More thorough extraordinary maintenance must be carried out by an authorised technician once a year. The technician will clean the flue, check the tightness of the seals, remove all residue from inside the stove (feed screw, fan, turbulators), check the smoke emission and electromechanical components.
