Have a homeowner wanting to install a Quietside boiler, the manufacturers installation instructions reference ANSI Z21.10.3 for termination clearances to an inside corner and a vented soffit. The other clearances it gives. Wouldn't you know they want to put it at an inside corner below a vented soffit. Anyone have those clearances?

Thanks.
 
Re: Vent termination clearances per ANSI Z21.10.3

If it is not listed in the installation standards of the equipment, for a mechanical draft venting system IFGC 503.8 and if it is gravity system you have to refer to IFGC 503.6.3.

The ANSI standard you noted is incorporated into the NFGC and the IFGC.
