Bay Vent 800 BO

[David C. Macy]

Anyone familiar with this typw of vent. I did an internet search and did not find any information.

The furnace was an 2004 mid efficiency American Standard. This vent was a double wall b vent and vented thru a masonry chimney.

I was concerned about the opening. I used an ambient C/O tester and had no recordable readings.

The house was 90 years old. I took a picture of the masonry chimney to see if there was a clay liner. I could,nt be sure if there is a liner or not.

The clean out door was held together with a piece of string. There was no exterior cap, the exterior chimney was previously repaired.

I advised to have the flue evaluated for a liner, cap & to fix the broken door.

I am not to sure about the Bay vent 800BO and this is were my question is.

Does anyone know the specs or any information pertaining to this type of vent?
