Friday Boiler Quiz

I know it sounds crazy but were they for a set of gauge glass cocks???

Does anyone want to guess what these holes are for

The "Extra" holes that were punched in the side of the boiler. Anyone want to guess why someone would do that?

I'm certain one of you savvy service guys will know. This is an older Peerless MMW series boiler. The only hint I will give is that the additional holes are not used for make up air.

You guys

are giving the previous "technician" wayyyy to much credit.

This is a (nat gas fired) CI Section water boiler. More guesses?

holes

They are access holes to get a wrench on the pump flanges.

We have a winner!

JC is right on. Some tech looking for an easy answer just drilled thru the boiler to gain access to the pump flange bolts.

Let someone try and drill thru our Knight boiler installs and someone will have to post bail money for me.

Yep, JC is right, I didn't even have to open the pics to know what was coming up! I usually use a sheetmetal circle cutter...way prettier...and then a sawzall for the bolts.

By the way...I serviced an MMW yeaterday...30+ years old. It still had the original Amtrol 110 on it, a GFS 20-42 on it, and the OEM gas valve. The Taco zonevalves looked original...the heads had been changed. It checked out with my handy dandy testo at 78.9 percent effecient. This boiler has been checked faithfully every year...mostly by me...and is there as a testimony that regular service makes a difference. I know there are boilers out there that are alot more efficient...but they aren't more economical. Why would I change this boiler out?

Looking at the picture...somebody did shorten the drafthood to make it fit. Cleaning those burners will require a "noodle-head attachement" for the service man.
