B-Vent Connection Questions

[gmanmdg]

I bought a Modine Hot Dawg Garage heater. The only venting solution I have is to attach the vent from the heater to the main B-Vent for my furnace and water heater. I already did the calculation for the current B-vent to see if it can handle the additional BTU'S and it can. Running up through the house is 5in B-vent. The run from the heater to the main B-vent stack is around 5ft. My question is: Can i attach single wall vent pipe into the B-vent? If so How do I go about doing that?

Thanks, Mike

Hi Mike,

Not to be unkind, but this is a home inspectors site, not a do-it-yourselfer's advice site. I think we were more than patient when you visited last time to ask your questions about the house-sized furnace you wanted to put in your garage, but we advised you then to see the services of a professional and explained, in many ways, how dangerous it is to do this work yourself.

Please, spend a couple of hundred bucks for a professional to come out and help you install that thing.

ONE TEAM - ONE FIGHT!!!

[:-angel] I just finished a NCI (National Comfort Institute) certification class on CO (carbon monoxide) and combustion and I would highly recommend against teeing 3 vents together, especially if one is forced draft . If you do not have the tools to check for proper draft don't do it. The chances of back drafting are very great with the production of CO likely.

be safe
