Convert Laars lite model lg125n to LP gas

That involves changing out the complete burner tray including the igniter/pilot assembly, burners and the gas valve. It runs deep into the cost of a new heater, (well over $1000, not installed).

We have a Jandy Lite @ Model LG125N pool heater. The gas pilot turns and stays on but the burners won't ignite? Looking for firection on potential problem and how to fix. THX.

The reason it doesn't light is that the electrically operated gas valve is not coming on. It could be defective or the control circuit that tells it to come on is not doing that. If you have a meter and can connect the leads to the wires on the valve you should get 120VAC when the control circuit tells it to open. If you don't get this then the control circuit is not telling it to open. With the power off, check the resistance across the thermal safety device. It is located usually on the far left. It has two wires and they connect to a small axial leaded device. If it gets too hot it opens and prevents the heater from coming on. If the resistance value is very low, under 1 ohm, then it is OK. Other switches that could be open include the thermostat switch, the water flow switch, etc. Any one of these would prevent it from coming on. If you call the Jandy technical support number they might be able to help you diagnose the problem. I hope this helps.

Have a dayton 3F405D propane greenhouse heater don't know where to light the pilot light.

Find where the gas line connects to the gas valve on the back of the heater, from the gas valve, follow a small aluminum tube going into the back of the heater. There may be a removable door to access the pilot assembly. If there is no aluminum tube, the unit has electronic ignition and no pilot lite. Turn the gas knob to off, then to pilot. Hold the gas valve in and with a long match or gas grill lighter, light the pilot. Continue to hold the knob in for about 30 seconds. After that, release the knob and check to make sure the pilot stays lit. If so, rotate the knob to ON. The thermostat will kick the burners on.

My name is Larry and I have an older model Vanguard natural gas wall heater. Igniter works and pilot lights, but pilot will not stay lit no matter how long I keep the control pushed down. As soon as I...

The part is ordered by Model number, a serial number is no help, and yes there is a part called the flame sensor that allows the gas to stay on, I am sure if you contact a local supplier they can provide a suitable substitute gas valve or sensor if it is a stand alone part, on most the sensor is part of the gas valve. I think you will end up having a local shop try and match up the valve.

There are two at the beach and they won't stay lighted. The pilot kicks on, then you hear gas, then it ignites with a big swoosh and immediately goes out. This happens over and over.

Sounds like the pilot sensor is dirty if you can see where the pilot light burns the will be a metal rod that senses the heat of the pilot and tells the burner it can come on. clean the rod with steel wool. even a little build up can shut the burner down.
