Boiler won't start

We have replaced our ignitor and our burner now when I watch the boiler light there doesn't seem to be enough gas shooting in. I'm not sure but I think I need to adjust the pressure. How do I do that?

Near one corner of the gas valve is a slottedplug.
It looks like large screw headremove the plug just like any screw. This lets you access the gas pressure adjustment screw.
Usually no more than one half to one full turn is needed. (clockwise to increase pressure)

It is important that you not have to much Gas pressure as this will cause overheating and premature heat exchanger failure.

The best thing to do is check the pressure going into the gas valve, and also coming out. Make sure the inlet side of the GV is not partially clogged where the pipe comes in. (especially if you have copper pipe with natural gas)

The boiler stopped twice during a week. The reset button was pressed whenever to start the boiler again(twice during a week). Is it abnormal? Does the reset button need to be replaced?


Good Question!-- Let's see if we can figure this out--

What kind of fuel are we talking about? - Gas or Oil?

Any clue as to WHY the boiler stops?--
Can you see a water level, or a temperature or a pressure setting/ gauge?
Tell us what some of these readings are--

If it is gas-- how does ignition take place?-- Spark, or ignitor ignition?

Where is the Reset button?-- is it on the burner control-- or the water level control?

Tell us more--

The boiler wont fire up and the blue light flashes once per second


Let's see what we can do to trouble-shoot this boiler--

First of all-- Are we talking about a Hot Water 'Boiler'-- In other words does this boiler heat water that circulates thru the house, to keep you warm?

Next-- What is your fuel?

Have you Shut the system down, to reset it?-- What happens when it comes back on again?-- Clicking sounds-- pumps trying to start-- solenoids trying to open, etc.-- Tell us what you observe-- so we can help you trouble shoot this problem.

Baxi solo pfl60 problem. the boiler has for some time been doing this - the fan starts normally when demand is present, then the pilot ignites, then it all shuts down. this happens repeatedly about 6 times...


One thing I would check is the flame sensor. Your boiler may not have this on it but I have seen them act like this before. If you have one I would replace it. Hope this is ofsome help. Thanks

Got a baxi back boiler about 20 years old works fine upto the other day when the heating is on the thermosate dos'ent seem to be working the boiler is just running on full all the time and not coming on...


Can you control heat with thermostat by turning it all the way down. I assume from your description that burner is running. If it is and turning t-stat all the way down made no difference I would remove t-stat from wall and remove red or white wires from it.This should cut power to gas valve turning burner off. If this works replace t-stat. Hope this helps. Thanks.

Showing F1 on display boiler makes a thudding noise then goes to F1 mode. Smell of gas.


Hello
Sounds like a low water cutoff switch is stoping burner from lighting.

Check that you have at least 15psi of water pressure on the boiler guage.

Try to reset the cutoff switches.

Gas boiler won't stay lit!


The burners and pilot need to be cleaned.
Turn off gas and power, remove the burners and pilot. Clean with a brass wire brush. (Steel wire can be used but very carefully) Remove all rust dirt etc. reinstall and it should fire right up.

Have a Rite Boiler Model No. 325 Serial No. 8419237 has dual draft with a balanacing damper and forced air exhauste. Problem: gas pressure is correct, but low fire first 2 burnrers fire but the other 12...


If it has only one ignition source then it sounds like a crossover is plugged or maybe one of the burners is not set correctly.

If it has multiple ignitors then I would suggest that a circuit board or relays are faulty.

Either way I would be very careful. If I remember right this is a big commercial steam boiler with 2 inch gas lines. That's a lot of gas.
