Prestige Triangle Tube Doesn't Produce Heat for Room

fivepointer

Hi,

I have a Prestige Triangle Tube (2010-46 Prestige User's Manual) that has not worked in over a year. Unit is still pretty new at <8 years old, I believe. We have 3 different stages in our home: one downstairs where the hot water heater is located, and the other two on the main level. Unsure if its failure to heat is related to a power outage we had where I recall the pump turning off and my kids keeping the bathtub water going until it was pumping brownish water.

Anyway, hot water in faucets and tub/shower works great. Propane is full and breakers all checked. I've tried resetting the machine and adjusting thermostats but the heat never kicks on in any of the units and I get a 6180 (i.e. "burner off due to reaching temperature setpoint"). Should I bite the bullet and call out a plumber or might this be an easy fix? Happy to supply photos if helpful.

6180 is 6 meaning burner is off due to hitting set point 180
its not sending the heat out to the system most likely due to a freeze up or bad circulator, or perhaps even air in the system.

Where are you located?

Hi Tom,

I live in northern Vermont. I'm pretty sure the circulator is good. It is a Grundfos alpha 15-55f. When I adjust the thermostat in the basement the panel that has the lights showing the heating zones lights up and the circulator has a display that works and shows activity. All pipes near the unit are cold to the touch.

You most likely have a bad diverter valve. That system needs a mag. type dirt filter to keep stuff out of the DV.

Is this a solo or excellence? Do the hot and cold domestic water lines connect to the boiler or a stand alone tank?

fivepointer

Hi,

Solo. Water lines connect to the boiler.

I can't help but ask: does your handle relate to your theological position?

fivepointer

Nice catch, Ironman. It indeed is.

What size is it?

Can you post some pics?

That is with out a doubt the strangest post I have seen so far.

The boiler, man; the boiler!

Boiler pics. I haven't seen a ton of them myself, but my wife seems to think it does the job...

Ironman

That's a Prestigue Excellence.

There's a 3 way motorized valve inside that diverts all the heat to the internal indirect when it calls for domestic. For some reason, the valve is not shifting to space heating once the domestic call is satisfied. It could be the actuator on the valve or the indirect's sensor.

I'm not sure on the old model, but I believe there should be a time override on domestic priority. If you have the I/O manual, it should tell you.

Is this what you're referencing?

Ironman

Yes, parameter 43.

Tom_133

Ive been to this house!! Thats a weird feeling.

You must have just bought this within the last year or so?

I bet its frozen, wouldn't be the first time. I have been there before to thaw it out.

unclejohn

My moneys on the diverter valve, you really should have a dirt-mag separater on that boiler.

Tom_133

unclejohn,

You may be right, but this house had a big woodstove when I was there last. The previous owners use to crank it up, and the finished basement kept the first floor pipes from getting any heat and under the porch out front it froze often,

It hit -30 here around the same time this post was started. I would check there first.

unclejohn

Tom I will defer to your previous experience, but rest assure I never wager more then a dollar.

fivepointer

Hi Tom,
That's crazy-- what a coincidence! We do have a wood stove, though I wouldn't describe it as big. What would you suggest I do? I haven't yet tested the parameter 43 setting. When you say its frozen do you mean one of the pipes, and if so is it likely that it would be that way both last season and this season?

Tom_133

Most likely, the heat zone for the first floor runs under the front door and between dining and living room I believe, thats where it typically froze in the past. I usually stopped in said hello to Mike the previous owner clamped on my Hotshot pipe thawing machine and in 30 mins or less I was gone.

I wonder... @Tom, did you happen to know either Bob Hood or Tom Mahar? Worked for the State years ago (like 40) as inspectors. They're the guys who taught me the trade.

Tom_133

I don't, but to be fair I just turned 40 and cant remember names to save my life. For some reason I can remember the orifice size on a gas dryer conversion from 10 years ago but no names. I associate everyone with the car they drive. With out that I am in big trouble.

Also please dont hold the wiring in pics against me, I went there to thaw pipes.

Hi Tom,

Thanks for all the tips. I sent you a message.

James,

I didn't receive anything, sadly there are more than one Tom on this site. I need to change my handle to TomVT

fivepointer

Tom,
Is your business called On Time Mechanical? I'd like to give you a call to discuss further!

James

Tom_133

Yes sir thats me.

My boiler is sending water to the external water heater for hot water in shower, dishwasher, etc. However, it keeps recycling and won’t send heat to the 4 units in building for heat.

Operates here for 10 minutes

Kicks to 6186 for 10 minutes

Lights don’t come on from units

Power appears to be off to the taco controller. Try to get that power on.

zittd

Power goes off on it when it recycles on the Taco controller. Always has

psb75

Well, then that is a "thing". No power to the Taco= no heat to the zone.

zittd

when it is sending hot water to the units the Taco Controller comes on. We have had this unit for 6 years and i have always wondered why when it "recycles" the taco powers off. When it goes back to 3150 and sends hot water, it comes back on. So you are telling me that the taco power light should never go off?
The guys that put this in told me that when it recycles it goes off.

Interesting right?

DZoro

Not sure why they wired it that way. The boiler itself will control who gets the hot water domestic or radiant. So there should be no reason to power off that controller. Don't know how he is controlling the taco control box. But sounds like however it was controlled has now failed.

Green light should stay on. It says, "Yep, I got continuous, steady power and am ready to work, by turning on some of them 'red' lights."
