And then its a matter of how the problem is handled.

We recently ran into a problem with a persnickity inspector who misinterpreted what a manufacturer had written in its I&O manual.

This manufacturer was Lochinvar. The inspector was holding the job hostage while he misinterpreted the book. Thanks to the actions of the local representative (Steve Duggan with Shamrock Sales), the manufacturer cleared up the issues and kept the job on target with minimal interruption.

I've said it before, and I will say it again. Lochinvar, be glad you have Shamrock Sales as your representative, and thank you Lochinvar for responding in a timely manner.

Stand up companies, both. I am glad they are my partners.

I bet...

I bet the inspector wanted a LWCO, and couldn't care less that there was a flow switch...

Just an educated guess...

Here's the deal...

In the I&O manual, under closet and vestibule installations, the manufacturer calls out 1" clearance to to combustible around vent pipes. Fair enough, it is a closed quarters condition right next to the combustor.

Further in the I&O manual, it talks about drilling a 5" hole through either combustible or non combustible materials, which equates to approximately 1/4" clearance.

Unfortunately, this inspector thought we were supposed to maintain 1" clearance to combustibles THROUGHOUT the building. Obviously, that would be rather tough to do when dealing with a maximum wall thickness of 5.5". We'd be drilling a 6-1/2" hole to accomodate a 4" (4.5" OD) pipe. Not a pretty site.

After all was said and done, the inspector told the GC that he "might have misinterpreted" the I&O manual...

What ever happened to common sense? This guy knew that the boiler was a zero clearance appliance.

I'm telling ya...
