Boiler goes Boom! when it fires up & shuts down

I had a new Triangle Tube Prestige Excellence PE 110 installed in April.

It's been running fine and we love it.

Lately we notice loud noises occasionally, not every time, when it starts up after a zone calls for heat, and tonight when it shut down after reaching the set point.

The noise is a loud boom or WHOOMP! It sounds like someone slammed the door on a car only 10 feet away. Or someone pounded on the house door just one time.

We notice it several times a day.

I plan to have the gas company who also did the install come check it out after the New Year.

Should we be worried? Worried enough for an emergency service call?

Thanks in advance,
RWS

Your natural gas company installed it ?

I would call it in as an emergency repair.

It's propane. Yes, the propane company did it. They sell to everyone in my neighborhood, and have a big service department. They've been very good to deal with.

Since the problem doesn't happen every time, I am reluctant to have someone come out, and not be able to reproduce the problem.

It must be gas is released a little before the flame lights up, so there's a little too much gas available.

I don't think I would delay in calling them. In fact, I would have called the first time I heard it...

Gas is nothing to fool with.

Take a pic of the gas line going to the unit....Just curious.. But definitely call them as an emergency repair. Should be under warranty and that is a serious issue and safety concern if its gas related.

Could just be a zone valve issue too. Take a pic of them too and all piping.

Sounds like delayed ignition and could be the result of several different causes. Definitely an emergency condition.
