Check the combustor in your catalytic appliance now.

While the weather is still warm and your stove is not in use, it may be a good idea to do your maintenance before the burning season begins.  
Remember the combustor is your heat source, not the firebox temperature.
If it is necessary to replace the combustor, I strongly recommend calling the friendly sales people at Applied Ceramics Inc. 
They will give you expert advice and the best prices you can find anywhere.

The right catalytic combustor is very important to the wood burning appliance's efficiency.
