Munchkin questions

The vapor is a normal occurence, but the noise concerns me. I would make sure that the gas piping is being supported by something other than the gas valve. I have seen that create noises (and broken fittings).

How loud should a Munchkin be? How much vapor in the exhaust?

Hi everyone,

My two-week-old Munchkin 199M seems louder than the ancient Weil-McLain 260,000 BTU monster it replaced. It's definitely louder in the boiler room, and as far as I can tell the noise is coming from the boiler enclosure, not the circulating pumps.

I'd describe the noise as a thrum, with a noticeable dip in the sound level every second or so ... thrum .. thrum .. thrum.

I can also hear the sound at night in the bedrooms ... where with the old boiler I might have heard water circulating, but never a thrum.

The other question I have is how much moisture should be coming out through the exhaust? Today was our first day in the low 30s with this boiler, and I was surprised to see big clouds of vapor coming out of the vent ... kind of like the vapor that comes out of the clothes dryer at the start of a load of towels. 8-)

I'm wondering whether the noise and vapor are signs that the boiler may not be adjusted properly. I'll be calling my contractor, but I thought it might help to tap the collective wisdom here.

Any insights would be greatly appreciated.

Thank you,

Yes, its normal

Wait untill it gets cold You'll really see it. Check out the photos here. I labled them as freeze-up only because they are winter pictures, not because of problems.

You do need to get your contractor back. It sounds like he did'nt set up the combustion correctly.
