Quiet side boiler lock out

Don't go home?

Quiet side boilers locking out

We have installed a few of the QVM9 quietside boilers. They lock out with no patern. No service code is displayed on the thermostat. We reset them and they run until I get home that night. Any ideas?

Laughed out loud

Frank. After some of the serious stuff the last couple of days this was great.
Are you now going to answer his question?

Mark Walnicki

This is sealed combustion?

Never saw one in operation, only got to check out a floor display, and I can't remember all the different fault codes that it can kick out. What about if that 3-way valve got stuck closed for domestic hot water? That would starve the building of heat, and they probably didn't throw in a code for that. Just a thought.

How do you like them so far? I was intrigued, but not that impressed. Have these things been approved by the code governing bodies in this country? What part of the country are you in?

Seriously, folks...

The online owners manual has a short trouble shooting section. The first thing I noticed is this line,

"Certain non hazardous failures will shut down the unit, but will not illuminate check light. Press ON/OFF button to obtain error code."

So, when you reset the unit -- presumably by pressing the on/off button -- does an error code get displayed then?

The trouble shooting chart in the owners manual points first to power problems when there's no error code. This reminds me of a story that was told here of someone that wired the boiler circuit to the basement light switch.

Turn the light on to go check on the boiler and everything's fine. Turn the light off on the way out and the boiler shuts down.

Oh, if you don't have a printed owners manual handy you can see the same thing I'm reading at this link:

We've experienced code 13 lockouts occasionally indicating low flow, had to return (1) QVM9 because of lack of tech support as to corrective action. New boiler that replaced it worked great for approximately 2 months then burped out a 13, reset and didn't lock out for another month.

Check out page 6 of the toubleshooting guide as I thought it contains some humor.

QUOTE: If the unit makes a sound akin to a "WOUNDED ELEPHANT" during combustion check the secondary gas pressure delivery. I've asked everyone in our shop and no one could replicate this noise so we know what to look for!

I've heard a wounded Elephant

and it's not something you'd like. Years ago, we lived in a row home abutting an atheletic field. A circus came to town & after the show, their one Elephant took ill. We spent many long hours attempting to get that huge beast back on its feet - to no avail. At one point, my neighbor & I almost got snared by its trunk, which would have been fatal. Long & short of it - the next day (a Saturday) they decided it had to be put down. They called in the police who then took all day shooting the poor beast. On each shot, the Elephant would scream out in pain. We sent our son (then age 10) away for the day due to how horrific the scene and noise was. It took them more than 8 hours & in the end, the carcas was taken away in a municipal dump truck.

Quite different from the captivating & eerie sounds of lions and tigers growling in the pitch black we'd head the night before from our back porch - kind of like being transported to the African outback!

I'm heading out to a botched radiant job tomorrow that has two Quietside boilers. The local supplier who handles them has stopped selling them due to having too many problems and they tell me there's two Korean dudes in the area who were sent here to check out the batches of failures.
