    When was this system installed? Has it ever worked correctly? A 6 zone system must be piped correctly and it is not simple. I install Weil McLain systems, and have to attend update classes regularly, so I need answers to my questions.

SOURCE: Boiler won't start

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)

SOURCE: Carrier furnace

I'm not a fan of zoning but it sounds like they don't have the ducting done correctly. There has to be bleeder trunks installed in the unit because your are taking a unit that is designed to cool or heat a particular square footage and make it cool or heat a smaller area. This makes the unit way too big for the job you are asking it to do. If the ducting is improper, you are going to have issues like this. A lot of contractors will not admit that the ducting isn't correct due to the cost to correct it. I personally think (my opinion) that 4 zones are a little excessive. Sounds like you really need 2 units. It's hard to tell from my point of view since I'm not there to actually see what is going on. I would have a couple of different contractors come out and give you an estimate to fix the issue and then tell the installer to come and fix what they say is wrong.

SOURCE: gas furnace, main burner ignites the other 2 don't. then shutdn.

Between the burners is a small rail in the pressed steel where the flame runs across to light the other burners and it sounds like there is dirt or debris in the step over rails causing the problem. You will need to use some compressed air on those rails to clear them out. Once the rails are clear the other two burners should ignite right away.

Why the hot water temperature couldn't reach the set temperature (130 degree) in Amtrol WHS80Z indirect water heater?


I have a couple of thoughts. You may have air in the boiler water circuit at the loop that feeds the tank. You'll have to find the vent in the loop to get it out. Second, the automatic valve that opens for hot water may not be opening fully. Have you felt both the boiler water lines that go in and out of the tank? If the water going in is hot and the line out is very cold you have very little boiler water going through the loop. Make sure the isolation valves on the loop are open. Is your boiler full of water? If the boiler loop lines are hot going in and coming out, the tank is full of rust or debris and no water can get to the fins on the internal tubing to pick up heat. If that's the case there is no repair and its time to get a new tank. Hope this helps good luck.

Automatic Damper


If the damper is buzzing i may be that the moex plug is not properly engaged at the plug and there is sone current loss through the low voltage wiring. If it is a field controls damper it is not uncommon for it to buzz when the plug is connected but ajar. Some times the buzzing is coming from a loose sheet metal screw that is vibrating when the damper is opening or if there are not at least three screws in every section of the smoke pipe if it is a single wall pipe, if you have B vent pipe check to be sure that the sections are connected securely. (they should be @ about 60 degrees apart between screws) and that could cause some buzzing when the damper is opening or closing.
As far as leaving it manually open you will loose heat up the chimney but the boiler will still operate with the damper manually open just not as fuel efficiently. Also check the jacket screws and draft hood screws sometimes they can drive you nuts over a loose screw.
It also could be that the motor is on the way out and you would have to replace it.
http://www.weil-mclain.com/en/assets/pdf/550142779_1212_CGaBoilerManual.pdf
Here is a link to the PDF file for that model page 48 will give you some information about the damper.
The boiler will not fire if the damper doesn't open (if it does fire with the damper closed shut it down and call a professional) if you want to check for loose screws it may help you out some. But you may leave it manually open all the time in the short term if it does fail but don't leave it open too long or your gas bill will start to pick your pocket.
Good luck I hope it was some help and look over the link to the equipment it may be helpfull

You don't have an optimum distribution of steam in your house. Try closing a little bit the valves supplying the heaters in the lower floors. Close a little bit more until you get the desired balance.

Thermostat temperatures not reaching preset Energy Star settings


Well with a boiler system like you have it will cost you more money to heat your house that way than if you leave it like it is. With a boiler system it takes a lot longer to heat an area than with a furnace. The best thing you can do is find a happy medium and leave it there at all times. If you read the paper work on your new thermostats they have a set procedure which tells the thermostat if you have forced air or boiler system. Do you have baseboard or in-floor heat how many zones do you have.

I have a radiant floor heating system with a wirsbo control system, i keep having to reset the system to get the zones to heat up again. The broiler is working fine. The first time I reset the radiant heat...


Is this a water circulating system? If so there are bleeder ports on your radiant heating zones on the floor that you can bleed the air out of the system. They look like a tire air pressure valve. Depress the valve core with a small screwdriver or something of the same nature. You will hear air coming out and water will come out. This is done while system is running. Also it may maybe under pressurized, circulating pump could be shutting down. Does the boiler keep running or shut down on reset. If it does could be within the boiler itself. Please rsvp with more info.
