Question about RTO W4 A.O Smith Gas Hot Water Heater Draft Inducer

1 Answer

Boiler Venting. Moved in to a 2 years old house. Has a hot water boiler Model GWI-095 N-I. Working fine. However, Big Gas bills are there. Searched the manual of boiler, found out that 5" dia. vent with 2-Elbows can go up to max. lenth of 48 feet. It has inducer fan. The installed vent is 3" dia + 2 90 elbow and the total vent length is 8 feet (Lot less than 48', hence very low resistance to flow of flue) Looked at the burner. It looks like flames are being sucked straight up in to the boiler without giving full benefit of the burning gas. I feel money is being thrown out of the boiler vent. I feel there should be controled venting of the flue. Can you please help me. Thanks.

There cannot be controlled venting of the flue , the products of combustion must have free flow to escape , The heat exchanger is above the burner which heats the water if you thinks this is high then maybe you a pressure problem . Or contact the makes tech line and ask them what they think the consumption might be for you heater .You may find this on google

SOURCE: After a few minutes of burner heating the water, gas shuts off.

A couple of things to check:

If possible, remove the pilot gas assembly and clean the gas jet and thermocouple - they can get carboned up and stop working properly. Make sure the pilot flame and deflector is aimed properly and making the thermocouple glow red hot. If the problem persists, you may want to replace the thermocouple and also check the propane regulator.

SOURCE: I have a Baxi WM old boiler. Hot water only needed

there should be a switch which toggles between hot water only /// hot water + central heating /// & possible off on
Either on the boiler or on a separate timer control

Water to hot for gas boiler boiler gos off


It could be dyslexia, but I think you want to know what may be wrong with your boiler in this case!
This is a VERY old design. The diaphragm is on the water section, this operates a switch to turn ON the pump, and a further device causes the diverter valve to divert boiler water from CH duty to HW duty.
From your description it appears that the boiler is shutting down on internal boiler water temperature (too high), your 'briefly too hot' HW symptom may be caused either by the boiler side of the secondary heat exchanger being blocked/caked in sludge, OR the DHW side of it being scaled. Either way a new or replacement (descaled) secondary heat exchanger MAY inprove things. It's not easy on these old clunk-pots, and EVERY disturbed seal will subsequently leak, so get a good supply of o-rings and fibre seals before you start ("you" being the competant fitter you employ)

When you turn on hot water tap the boiler fires up hot water for a few seconds the water becomes cold the boiler flame goes out then fires up again. when the heating on the flames stays on then off then on...


To avoid having a flame in the absence of water flow, the device you mentioned, 'diaphragm,' detects if adequate water is flowing to avoid a dangerous condition. Check on the housing of it for an adjustment screw; it may have a dot of sealant on it since these normally can be adjusted. It sounds as if it is misjudging the quantity of water flowing through and causing the annoying cycling.

Boiler leaks when shut down


Hi,
I hate to tell you this but you probably have a leak in the casting of the boiler...it is very slow... therefore the water will evaporate as long as it is hot and you do not see the water...but if you let it cool , not only will the casting shrink and open the hole a bit, but none of the water evaporates....
After 35 years it is time to replace that boiler...

Hot water


there are two main faults with combi boilers not giving hot water. one is a faulty flow sensor, the other is the most common which is a blocked heat exchanger caused by debris and scale in the system. this needs to be flushed out or may require a new heat exchanger depending on the age and condition of the boiler some plumbers may suggest a new boiler.

The hot water and central heating wont work together


what size of gas line is going into boiler and water heater? is it black iron ? natural gas or propane? have you checked gas pressure at water heater and furnace ? if they work fine individually then you have a problem with incoming gas pressure. Call gas company and ask them if they would come out and check gas pressure.

Very Hot water coming out of overflow pipe


Is your boiler heating your domestic hot water if so i would turn water off to water maker and see if your boiler pressure stays down below 20 psi. If so water maker is bad. The other thing that could cause this problem would be the boiler pump is out.

Valient combi boiler is not heating the water properly


vailant boilers are one of the best on the market and should last you more than 6 years depending on installation and servicing.
the engineer you had should not have replaced the diverter valve if the boiler was firing up when the taps are opened. if you was getting luke warm water with the boiler alight it is a classic symptom of a blocked plate heat exchanger on the central heating side.
a new heat exchanger can cost around £100 depending on the age and model of the boiler.alteranatively it could be descaled but may clogg again. it would be a good ideal to fit a magna clean filter on the system to help prevent further debris if you have a dirty system .if you don't trust your engineer i suggest you ask another. find out if he is registered first and don't pay until you are satisfied with the work. if you are asking the same engineer back try and get a discount off the work as he has failed to rectifiy the original fault and fitted the wrong part due to wrong diagnostics. if he is registered you can complain to the governing body ie corgi or gas safe register.
good luck.

Gas boiler


hi sounds as though the system is sludged up & needs power flushing.the reason is that the water cannot circulate so over heats & pumps into the header tank.
expect to pay approx 350 400 pounds to have it properly cleansed, it will restore the system efficiency.
The other area worth considering is that it could be a faulty pump os that when th eboiler fires it cannot circulate so in turn expands & vents into the tank.

My advise is to arrange for a corgi engineer to sort it out for you.

Kindly
