I have an Anthratherm VA600 and was wondering how the air enters the pot. I looked at it and it appears that the the air enters thru the gaps in the rings of the pot. Please let me know if I'm right. Thanks.
Thanks for all the responses and suggestions. I'll tackle that chore in the spring. Furnace seems to be burning a lot better now. Are the bolts easy to replace if I snap one off? Thanks for any help.
