Venting Buderus GA boilers

Ray Landry

I don't have adobe acrobat reader, and don't have any buderus manuals offhand. I'm hoping someone here can tell me what the maximum vent length for a Buderus GA124#17 is, and how much footage do you allow for one elbow?

Download

the Adobe acrobat reader (it's free)from the Buderus site and read the manuals. This boiler has particular venting requirements and you'd want to know the details.

The GA124/17 can be vented up to a maximum horizontal length of 50 feet. There are four manufactures of 3" stainless steel AL29-4C that are approved for use. Most of these manufactures equate a 90 degree as ten (10) feet. You may want to check with each manufacture if length is a concern.
