Question about Dayton Gas Furnace Heater

1 Answer

We have a Hydrotherm gas fired Furnace in our home

It intermitantly ( every few days ) fails to ignite the Hot Water Heater. Local plumbers have told us to just jiggle it which works but we don't think that is a proper solution. Any Ideas?

Hi,
Sounds like a loose wire somewhere...
That can be a bugger to find...
if you wiggle the wires in the dark can you see any sparking...
also see if you can narrow down which wire exactly needs to be wiggled...then check the connections or look for corrosion at the ends of that wire...

Gas exhaust smell when Hot water heater ignites


Absolute danger here:

1) Call gas company IMMEDIATELY to check for gas leak that can cause explosion and fire.

2) Call plumber immediately to fix improper combustion or improper vent before toxic combustion by-product kills family.
Gas appliances must vent toxic by-product outside and away from home where the gasses will kill the planet instead of you.

Hot water heater sweeting from top


Water on top of gas heater can be caused by poor venting, or inadequate combustion.
Make sure water is not coming up from under tank top, indicating tank leak requiring tank replacement.
Have a plumber look at problem to make sure home is not filling with deadly, odorless CO gas.
Inspect pipes that they are not corroded and covered with condensate.
Check that roof cap is in place.
Let heater fire and burn for a few moments so the fire is going good, and then light match just outside the draft hood on top of heater. Blow out match and see if smoke draws immediately into vent and upward.

Why heater coils glow?


It sounds like you're describing one of two things. The hot surface ignitor in a gas-fired furnace, or the resistive heat strips in an electric furnace.

The hot surface ignitor in a gas-fired furnace lights the burners. This ignitor in modern furnaces serves the same purpose as the standing pilot flame did in older furnaces. It provides the required heat to ignite the gas at the burners. Without an ignition source, a gas-fired furnace cannot provide heat. When the ignitor is activated it will glow bright orange or yellow.

The resistive heat strips in an electric furnace actually provide the heat to a home or building. When the furnace turns on, the heat strips are activated and usually glow orange when they reach peak temperature. In almost all cases, the heat strips are not easily seen or accessed without removing covers or panels inside the furnace.

My gas furnace fires but then cuts out. There is a similar post on here about this but my problem is a little diiferent. The unit kicks on, fires then shuts right down. The blower comes on and stays on....


HAD A similiar problem last week with a customer who had just installed a pool and running off of propane tank for gouse as well... he let tank go empty and started having problems ..what we ended up finding is that not only was his regulator on tank bad he needed a additional regulator to regulate the different psi pressure to the appliances... get them to check your regulator out

When the hot water heater is running water leaks from the chimney. the pipe from the heater to the chimney is dry upon removal. about 3 gals. of water leaks from the chimney with two showers.


If I understand correctly, your Bock gas water heater vent is causing water to leak down into chimney.
This is a very serious concern

Water leaking from water heater flue indicates improper venting.
The hot air gasses from water heater combustion contain water vapor, but the gas should vent out of house before condensate forms on pipes.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html#flue

The problem might be caused by a power vented furnace that pushes vent air from furnace down into flue pipe for water heater. As a result, the water heater doesn't vent properly.
There could also be a clog.
Light a match under water heater draft hood and see if smoke from match travels instantly upward.

There are two major concerns.
1) If vent is not working, it means that odorless CO gas is entering home instead of venting outdoors.
CO carbon monoxide is deadly poison.
http://en.wikipedia.org/wiki/CO_poisoning
This is a very serious concern
You can buy CO detector after vent is repaired.

2) Water condensate will eventually rust away vent pipes because of acidic content of the combustion vapor. It can be expensive to replace pipes, and pipes with holes pose risk of CO poisoning.

My suggestion is call a qualified plumber ASAP and explain what you observe.
Plumber will want to inspect the vent pipes, and may want to extend water heater vent pipe up further inside chimney so furnace is not pushing air back into water heater vent.
Plumber may also find blockage somewhere in the vent stack or chimney.
Also post on a professional water heater forum like the Tank to double check anything the plumber says to you. These are the pros.

If you have a leaking water heater there is a serious problem.
http://waterheatertimer.org/Water-heater-leaking.html
Page shows how to limp along on a leaking water heater if your water heater needs replacement.

One of three things is causing the water:
1) Loose water connection on top of tank that is dripping down inside tank >> check pipes on top of tank.

2) The vent is clogged or not working correctly causing condensation inside flue pipe.
Condensation water is dripping back down inside tank.
Problem means possible CO poisoning if gas is not venting.
Look at vent pipe to see if joints are corroded.
Use long fireplace match > light match and put into draft hood at top of tank and see if smoke goes up.
Put hand at draft hood opening when water heater turns on to see if vent gas enters home.
Do same test when furnace turns on to see if furnace vent is pushing back into water heater.
Does water heater vent inside same pipe as furnace? You may need to set up separate vent for water heater if furnace gasses are pushing back into home.
Check furnace vent for obstructions.
Look at vent stack top of home to see if hood is in place.
Check if bird nest is built inside warm vent pipe.
Improper flue is top priority for getting fixed so vent gasses properly escape home.
You may have to call a plumber.
Professional plumbing forum:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

3) Your water heater is rusted out.
A rusted tank has to be replaced.
It cannot be repaired.
However, before replacing tank, you do not want a tank failure where tank ruptures and water runs inside home until water is shut off.
This will cause major damage.
Protect yourself first.
Turn off water valve above tank.
Move gas knob to 'pilot' so burner is not heating water.
Open tub spout on hot side to relieve pressure on tank so it will not rupture.

Now you're protected.
Link above shows how to limp along on failed tank until you can replace heater.

You need a new gas water heater from Lowes or Home Depot
Look at label on side of you tank for gallons and btu's of your water heater.
Measure height to flue pipe so you get same height water heater, so pipes don't have to be changed.
You need a pipe wrench and teflon tape which will be wrapped on each pipe thread when pipes are reassembled.

Step1) Drain water heater using valve at bottom of tank.
http://waterheatertimer.org/Water-heater-will-not-drain.html

2) Turn off gas valve going into heater.
When gas valve is perpendicular to gas line, then gas is off.
Dissemble gas line to water heater.

3) Disconnect flue pipe and support flue pipe with wire so it doesn't not fall down. Flue pipe joints should be held together at each joint with 3 screws.

4) Turn off water. Shut off valve is on COLD side.
Disconnect water pipes.

5) Move old water heater out of way.

6) Set new water heater in place. Put water heater in drip pan.

7) Connect water pipes >> cold goes to side marked cold.
Hot to hot.
Buy new flexible water connector pipes at home center for easy installation of water pipes.

8) Connect gas line exactly as it was connected before.
Home center sells flexible gas line connector for easy installation of gas line.
To test for gas leak after installation, mix liquid soap with water and put around gas line joints to see if there are bubbles.
Natural gas has less pressure than water lines, so gas pipes are easy to seal with ordinary wrench.

9) install TP pipe that runs to floor. Use old one off old heater.

10) Fill tank completely with water until water is coming out of tub spout.

11) Turn on gas, and light pilot as shown in manual.
New gas heater sometimes have small water leak when first fired up, so ignore a bit of water.

12) Save water heater manual like it is gold, and read everything in manual.

I have a gas furnace with electronic ignition. Can't find a brand name or model anywhere. Intermitently the thermostat calls for heat, blower fan comes on, igniter comes on, and then either all the heating...


Hopefully someone with more experience will respond as well, but my experience with this type of furnace is that this is likely to be a clogged line or gas feeder control device. The behavior indicates that there not enough gas being presented to the unit. Unfortunately this is NOT a DIY type of repair. A licensed plumber should examine this unit. Gas units can be dangerous if not serviced properly. Please seek local assistance frmo a professional.

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.
