SOURCE: Venting a Dayton 4E454 24,000 BTU gas furnace

If you intend to use this in a residential garage, you will have to use standard galvanized round pipe coming off the unit, 24 gauge will suffice, use a minimum of 6”-8” from the unit. From there you will have to make the transition to the B-Vent. Always double check with you local codes in your area.

Hope this helps.

Contact Dayton on the internet for this problem. The diagram should be available on their site. Or they will give you a number for customer care. They can give you step-by-step instructions. I am a technician and this is what I would do as their are millions of wiring diagrams. Many are noy up to date.

SOURCE: is the flame sensor for a weatherking 125000 btu

Hi,
What you bypassed was the hi-limit switch. This is a most important safety control. If the furnace heat exchanger compartment gets too hot this control cuts (opens up) the electrical circuit to the gas valve and shuts the gas flow to the burners. After that little round disc cools down to a certain temperature it will close the circuit and your furnace will run again until it overheats and does the same cycle. There is a reason this control is tripping on you. Your furnace is overheating consistently for a reason. The first thing I would look at would be the air flow thru your system Is your air filter dirty?If is is very dirty you lose your airflow thru the heat exchanger compartment and the hi-limit will trip like i explained before. Are all your supply air and return air registers open and not restricted in any way? They all need to be open. Do you have central air conditioning? The cooling coil in the plenum above your furnace(if your furnace is in a basement) may be dirty. You will need an experienced service tech to check it and clean it if it needs to be cleaned. I have ran into many systems in my business where the furnace is oversized for the size of the house and the furnace will consistently cycle on and off on the hi-limit contol for years util the hi-limit gets weak and fails. If that is the case you need to get a smaller BTU furnace as that is the only cure. Sometimes the ductwork was installed to small and you can't get enough air flow(supply or return) if thats the case there's not alot that you can do if all the ductwork in buried in the walls and ceilings. You will still need to re-install the hi-limit with a new one. It hase to be the same temperature rating as the one you took out. Contact your local dealer for one.
On your question about the flame sensor, it is the small probe that is actually on the last burner(the last burner that gets gas and lights). It is held in place by a single screw and has 1 wire going to it. Hope I was of help to you!! Good luck!!

Just moved into this house and notice the furnace not working right It is and older unit know name or writing on it I rehooked up wiring to it but now blower run all the time and the only to shut off is...


Older furnaces used to have a fan switch that read winter or summer, or auto and on. You should also have a fused switch to the furnace, wiring runs black to the switch thru the fuse and to the furnace black wire. White wire is straight to furnace from electrical panel. This is for power feed to furnace only. Now the thermostat is red to the transformer white to white. This was a very simple old furnace they had very little safety devises. The fan switch was an older high end model so you could blow the cool air from the basement thru out the whole house in the summer, and the fan ran constantly.

I have a 75k BTU Dayton hanging gas heater that the fan comes on intermittently. The flame will shut down and try again, then the fan will come on.


This problem is caused by a bad flame sensor (looks like a spark plug) which can be cleaned by sanding or with steel wool.

I have a 25,000 BTU hanging furnace, will this heat a 900sq foot garage that has been insulated.


Here in Vermont we design heating systems to perform at -10 to -20 degrees. Depending upon how tight the doors and windows are, it may if your temperatures don't drop below 20 degrees. It may take a while to heat up and I would not expect any temperature over 62 degrees inside the garage. Maybe a 50,000 Btu heater? Remember the output may be 20% less than the rated input of the heater.

Installed dayton nat gas hanging furnace in garage and have 2 wires dont know where they go one came from the back side of the transformer it was twisted with the other wire


Hopefully there is a wiring diagram glued to one of the panels to verify but on the transformer you will have 2, 110 volt wires. One is the power coming in (usually black wire) and the other is a common (white wire) and will be connected to other common leads. On the low voltage side of the transformer one wire will go to the thermostat then from the thermostat to the gas valve. The other side will connect to the gas valve. When the thermostat calls for heat it completes the circuit from transformer to gas valve back to transformer.
