Did you also change out the oriface to the pilot assembly. you have to do that, also do you have a manometer (preferably digital) to check the gas pressure on theinlet and outlet of the gas valve? do this and set it up to the manfacture's recommendations and you should be good to go. Thanks for using Fixya and Merry Christmas!!

HOW TO CHANGE OVER FROM NATURAL GAS TO LP


There are some variations from one manufacturer to the other but basically they are all similar. If you have a gas valve that is convertiblble then normally there will be a screw plug cover on the gas valve where you can change the pressure for L.P. by removing the plug and spring and inserting a new spring to compensate for different gas pressures.You will need instructions for your unit as some require a specific number of turns on the plug to put proper tension on spring so gas pressure is right. On some units the burner orifices are adjustable on others you will need to change orifices on burners and pilot light.
If your gas valve is not convertable then you will need to get one that is. Hope this helps you. Thanks.

My new Laars JVS 225 boiler make a whining noise when heating up. It does it on all zones. This was a replacement for a Teledyne Larrs that had a leak but ran quiet. IPressure is 15 lbs and temp is 155...


My new Laars NeoTherm boiler (NTH150) was making a whining noise soon after install. The noise was audible through most of the home. Replacing the air/gas blower solved the problem. Correct sizing of pumps is also important to reduce (water-flow related) noise. Having done all that my Laars boiler still isn't particularly quiet in its start-up and (modulating) operation. It should NOT be located below or next to a bedroom.

I have an older Teledyne Laars EPS Gold Series One pool heater. About a year ago, I had a new Jandy igniter installed. Now, the pilot light goes on and simply burns -- it does not ignite the full burners...


You need to see what what pressure is required to turn the heater on. If you don't have enough flow or pressue, the heater will not ignite. Was it working before?

I would like to convert my water heater and boiler system to natural gas


If you are using LP, you will have to change the orfices and spring in the gas valve. The problem is, if the boiler is over 5yrs. old you will have a real hard time finding these parts. You could
probably change the gas valve, but probably no luck on the
burner orfices.

With the Water heater, it is probably cheaper to replace the water heater.

I know all too well what the issue is. Sometimes it self corrects and sometimes not - then you take apart the top side of your heater and pull the manifold/tubes. There are rubber gaskets that probably dried out over the winter. You can try to just tighten the manifold cast iron headers to the tube flange but, if you have it this far, just install the new gaskets. Teledyne Laars sells them in a pack of 18.

Goodman gps100-4 heater, tied to heat pump intermittent gas valve operation. all safeties check ok.


If you have 24v to gas valve and a good ground to unit, check gas pressure with a manometer to ensure your input gas supply is correct..11-13" w.c. for LP and 5-10" w.c. for natural. If out of that range, valve may not open. You have to ensure you have 24v to valve after ignitor comes on..about 5-10 seconds after ignitor starts glowing. I would check from pos side of valve to chassis ground. If you do and your input pressure is good, you have a bad valve. Monitor the voltage to the valve to make sure it does not lose partial voltage during the 3-4 seconds it is energized before the flame sensor stops the sequence. And keep the manometer on the input side while the unit is firing so you can see if the pressure drops when the gas valve opens. If it does, your regulator outside is not working right.
If those look ok, see if you get output pressure when it does not fire. If you do...3.5" for nat, 10" for LP, the ignitor may not be getting quite hot enough every time.
Hope that helps a little

I have a problem with my heating system. It is about 10 years old and has had the ignitor, combustion blower motor, and programable thermostat replace in it's lifetime. The system worked great last year....


sounds like its not proofing flame. it has a sensor usually like a needle sticks out into the flame that tells the gas valve the flame lit and is burning so its ok to keep sending gas, if its fails to proof flame then burner shuts down, then it tries to relight 3 times then locks out on fail safe. the blower will sometimes run continually once that occurs to highlight a failed condition. every time you reset it will try again 3 times then shut down. lp gas is very dangerous, even i do not work on it as the gas acts like gasoline and lays around. not like natural gas that disperses well. if you see the flame sensor try gently cleaning it with a little emory cloth. also a loose ground can cause this. check tio be sure any green wires are snug , they actually flow volts to ground through the flame on some to proof, thats why no ground no flame. if that fails then the board is most likely problem. change wire for wire , or get generic replacemant and follow directions exactly. good luck.some ignitors act as a flamre proofer as soon as they are done igniting! rarely do they fail to perform both funtions.

Laars Lite 2 pool heater will not fire. Pilot is on and I replaced the pressure switch. Had a similar problem at the start of the season but left on for a few hours it finally kicked in.Water pressure in...


I believe that the Laars Lite 2 heaters are a millivolt system . There is a thermopile in the pilot assembly that produces about 500 millivolts DC. This is the power that the gas valve uses to turn on. These pool heaters are notorious for getting resistive connections that restrict the flow of electricity through the circuit. A connection that looses 1/4 volt is no big deal with 110v but in a millivolt system that is half of your power. Start by checking the output of the thermopile then go through the entire circuit and clean every connection with sandpaper. usually this will fix it but if not then you will need to isolate each individual component to find out what is not passing power.
Good Luck,

OIL WONT WORK IN THE PLACE OF LP OR VICE VERSA!

And correct You can addapt SOME burners to LP. Check with MFG to be sure. SOme Burners are dedicated to 1 fuel only IE LP only or NG only.

The LP has no regulator needed at the appliance it is regulated at the tank regulator, or on some 2 stage systems at the inlet to the building.

11" - 13" water column is the range for LP

If you cant find any MFG to answer your question take the name off the GAS valve you use and any model number on the gas valve and attempt to inquire form those numbers as to availability of lp change over. IF YOU DONT FIND ANY MFG OR INSTRUCTION MY ADVISE IS EITHER REPLACE THE VALVE WITH ONE THAT YOU KNOW IS APPROVED. A safety warning here is worth all the money because you cant save enough on the price of a new heater to replace any body and very few houses. Keep in mind that the spuds or orfices have to be changed also and some burners require reset of the Combustion Air inlet.
