central oil heater chimney

[paulmars]

For reasons unrelated to the oll heater, Id like to move its chimney from venting thru the roof to going out the side of the garage wall. This will involve making the pipe longer and much of that increase will involve the pipe traveling horizontal.

I know that i will need to readjust the barometric damper afterwards.

Any other concerns or things that i should know?

the original bryant install paperwork gives no info on exhaust. I asked them and they said that

I need to ask my authorized dealer.

The original beckett paper work actually gives more info. Like 1/4" rise for every 12", might need an exhaust fan to pull the exhaust out, if exhausting to out side of building, it's better to have the combustion air intake going thru the same wall to balance the unit. that last one I really dont understand and would rather leave the intake in the garage.

How would that exhaust fan effect setting the damper?

what else?

Hi there!

It sounds like you’ve got quite the project on your hands with moving your oil heater’s chimney. When extending the pipe and shifting the venting from the roof to the side wall, there are a few things to keep in mind. First, make sure the horizontal sections of the pipe have the right slope—about a 1/4-inch rise for every foot of horizontal run—to prevent any issues with condensation and ensure smooth operation.

Since you’ll be adjusting the barometric damper, keep in mind that adding an exhaust fan might change the draft dynamics. This could mean further tweaking the damper settings to avoid any over-drafting or pressure problems. As for the combustion air intake, while it’s generally better to have it on the same wall as the exhaust for balanced airflow, you can keep it in the garage if you prefer. Just watch for any signs of draft or air imbalance and adjust if needed.

It’s always a good idea to have a professional take a look after you’ve made the changes. They can ensure everything’s up to code and running safely. Hopefully you have already completed this amazing project!
