Type B and Type A vents?
Type B and Type A vents?
(OP)
Dumb quesiton perhaps: my local Gas code calls for Type B vent for Category I appliances, and Type BH or"special venting" for Cat II, III and IV. I have seen some manufactures also mentioning Type A vent required for their appliances which is not mentioned in the Code.
I have no problems specifying and obtaining this from suppliers and manufacturers but, what makes a Type B vent? Double walled steel?
What is a Type A or BH Vent?
