Wall furnace? maybe and maybe not! if there is a way it would be on the gas valve and be labeled (though it might be hard to read). often the adjustment screw is under another screw but always labeled.

How to light pilot on Dayton furnace and then start furnace


If this is a standing pilot system, turn the gas valve to pilot position. push in the knob & hold while lighting pilot...keeping holding knob down for a minute... this will pick & hold the gas valve. Let go of the knob & see if the pilot stays lit, if it does, then turn the knob to on position & the furnace should start if there is a call for heat from the thermostat

Heater doesn't come on?


The electronic ignition system in a gas furnace is a modern development that allows more reliable performance than standing pilot furnaces, provides energy savings and contributes to better furnace efficiency (AFUE). With a standing pilot, found most commonly on older low efficiency furnaces (55% to 65% AFUE is not uncommon), a small gas flame is always burning and is known in the lexicon of American home repair as a "pilot light". The problem with this type of "analog" ignition is that it wastes energy by constantly burning gas and can sometimes be unreliable. These issues have led to the development of electronic ignition systems for mid to high efficiency furnaces that exceed the U.S. government's established minimum AFUE rating of 78%. The electronic ignition occurs typically in one of two ways:
  • Intermittent Pilot, or
  • Hot Surface Ignition The intermittent pilot system uses an electronically controlled high voltage electrical spark to ignite the gas pilot and then subsequently the main burners, when the thermostat calls for heat.
    The hot surface ignition system uses an electronically controlled resistance heating element not unlike a light bulb filament (and shown in the photo above), to ignite the gas burner.
    It is important to understand some of the other components of a modern furnace that you will encounter depending on the type of high efficiency furnace you have. Why? Because they can also come into play in repairing an electronic ignition furnace when it won't run properly. Let's take a quick review of the types of furnace designs and components found in high efficiency furnaces using electronic ignition.

    No ignition on dayton gas furnace. how hard is it to install new gas valve on a dayton furnace


    not hard but before replacing check pilot light and thermocouple for proper function and setting if pilot light not in right position thermocouple wont open gas valve if electronic ignition check for power and proper gap on igniter also check stat for proper function

    Dayton Furnace - Pilot Light Goes Out but Fan keeps running?


    Pilot lighted furnaces have a thermocouple made from disasimilar metals that when heated create electricity to actuate a relay that alows the gas to flow to the furnace.

    When the thermocouple gets coated with carbon from the pilot lights constant burning it acts as an insulator and keeps the thermocouple from getting enough heat to generate electricity, a very good safety factor.

    What you have to do is locate the thermocouple it should be located over the pilot light, you will see a gray substance around the thermocouple it will be hard like cement, take a knife and scrape away as much of the gray material as possible then sand the themocouple with a medium sandpaper until it shines, use one of you wifes emery boards, this should solve your problem.

    Flames burn then die down


    it sounds like you may have a dirty pilot tube or a weak pressure regulator. I would try blowing out the pilot tube to make sure it is clear and if that does not work then replace the regulator.

    Pilot wont stay lit installed new gas valve and new thermocouple


    Is this a standing pilot furnace, or electronic igniton?

    If standing pilot, does the heater use a fan to blow air through the heat exchanger?

    If the answer to those questions is yes, then check that the pilot orifice is not partially plugged and that there is a strong pilot blowing against the thermocouple. If there is, replace the thermocouple. If not, check the orifice again, and check that the inlet screen to the gas valve is not filled with gas line trash.

    If the the pilot flame is good and it continues to go out, the thermocouple magnet in the gas valve may be weak. Replace the gas valve as to get just the magnet and coil is not easy.

    Reply back any questions you may have.

    Fault Code on Dayton Gas Furnace


    This happens when the furnaces tries to light to many times and doesnt succeed. If you stand in front of the furnace while it is coming on, you will be able to hear the problem. If its an electronic start, there will be a clicking sound, followed by the gas valve opening to start it. If it has a pilot light, make sure it is lit, then listen for the gas to come out, it will make a hissing sound. If no gas is coming out, first double check to see if the gas is turned on to the unit, if it is, then its possibly the gas valve. Oh, if it is electronic, and you hear gas, but dont see a glow inside the furnace, or no glow or gas, it could be the ignite. Hope this helps.
