Methods of cleaning the combustor

Cleaning method #1

A vacuum cleaner may be used, but never use high pressured air to blow the cells free of any build-up. This can damage the cell walls.
Any cell blockage can be removed with the use of a pipe cleaner or a cotton swab.

Method #2

Should the combustor’s cells become masked with fly-ash,...use a paintbrush or soft-bristled brush and dust the combustor gently.
Never use anything abrasive to clean the combustor.

Method #3

Normally the catalytic combustor requires little or no maintenance because it generates such high temperatures, it is basically self-cleaning.
However, should the combustor become masked with soot or creosote, it is possible to burn the accumulation off by opening the bypass and building a hot fire.
Once the hot fire is created, close the bypass halfway and burn for 30 to 60 minutes with the bypass left in this position.

Never use cleaning solvents to clean it.
It would be wise to check and clean the combustor, if necessary, before each burning season and inspect the flue system for any signs of creosote build up.

A clean flue helps prevent chimney flue fires.

I like to use those low pressure air cans. They can blow the fly ash out better than using a vacuume or brush.
What about the 50/50 distilled water/vinegar boil? Other cat manufactures recommend this for heavy use an major clogging?

Hi Wobdee,
In reply to your questions, low pressure air is fine to use if it does the job for you.
As for the 50/50 solution of white vinegar and distilled water....this to is okey to use. The only reason this is not recommended by me or Applied Ceramics, is because of liability involved with instructing consumers to boil water.
The thing to remember is, the combustor will clean itself if it has a chance to light-off. Freeing the cells of any masking or clogging will allow this to happen.
Thanks for your questions and I hope this has answered them to your satisfaction.
