Modulating Condensing Boiler combustion air

Modulating Condensing Boiler combustion air

Modulating Condensing Boiler combustion air

I have a mod. con. boiler that got water and then rust in the cabinet from intake air condensation (separate and not related to the condensate drain). The venting setup is a concentric wall vent that splits inside between combustion air and exhaust. The manuf. is now suggesting to go to full concentric pipe all the way to the unit in order to help preheat the combustion air…

I'm thinking that condensation will still be a problem. Thoughts?

RE: Modulating Condensing Boiler combustion air

Manufacturer suggestion plus insulating the vent pipe should minimize or eliminate condensation.

RE: Modulating Condensing Boiler combustion air

Yes condensation will really create an another problem. There are some more methods of venting setups, which will help you. See these methods at this website
