    Would it be safe to convert this by changing the gas valve if so do you know what gas valve would be recommended

    I would like to safely convert my Cozy CF503C counterflow wall furnace from Nat gas to LP. I was going to change the orfice, but noticed a sticker on it that read DO NOT CONVERT. So I'm wondering what is the safe way to convert this furnace. Do I need to but a new gas valve, if so what valve is recommended, is there anything else I need to change to safely convert this. Thanks

    RULE OF THUMB: When it comes to combustible systems, believe the
    original equipment manufacturer. If they tell you not to convert it,
    dont.
    I sent you specifications for your counterflow wall furnace, which
    contain the advice to contact the wholesaler from whom the unit was
    purchased for further information.

Hi
There usually is a metering device in gas valves for accepting natural gas and propane. You need to find out if yours has that ability or just purchase a new one which is inexpensive and probably the right way to go and install the new valve. That is the only adjustment needed

If they don't offer a conversion kit it's game over! It cannot be legally converted. If you go ahead and alter the appliance and somebody is hurt or property is damaged by it, you will be liable, and insurance companies will not cover you for losses.

You will need to contact the manufacturer to find out two things...Is it convertable, and what parts etc. are needed to do that. If they will provide both of these things, you are away to the races! Install the conversion kit and new rating plate, and you are done.

By the way...Most manufacturers supply the units from the factory set up for NG and provide propane conversion kits. There are very few appliances that can not be converted from propane back to NG. There ARE a few, but not very many!

Change out the gas flow orifice size to propane.


Purchase a new one which is inexpensive and probably the right way to go and install the new valve. That is the only adjustment needed.

Thanks.

You need to find a brand that does allow for the conversion....As you probably noticed the orifice is removable on your model.. The reason for the sticker stating not to convert is because of the liability issues that the mfr. doesnt want responsibilty for....The safest way is to call the gas co. Even if you have to tell a little white lie that you suspect it might have leak...They will come out for free ..At this point befriend the gas man and pick his brain for the answers you need....I myself have converted my LP barbque to natural and it also had the same sticker.... So it is possible...Good Luck

You need to replace the gas valves for ones that accept propane, and also to replace the meter.

The job is quite complicate, I can do repair many appliances, but I would need to call a technician to do a conversion, there are also many safety issues involved.

I would suggest you not to convert it as it may be dangerous because such coverting and altering may result in leakage problems further.

Not really sure which model you have but when converting the over, ether bake or broil burner you tighten down the orfice cap. If you remove the burner off the oven valve you will notice that you can put a wrench on the orfice cap. Just tighten snuggly. If you over tighten you will crush the orfice under the cap.

How do i change from lp gas to natural gas on wall oven


First thing you will need to do is find out from the manufacturer of the oven if there is a conversion kit available and if the appliance is convertable. If there is then you can order the kit and follow the installation instructions. Also check the back of the oven for an envelope that may contain the gas orfice replacement heads to convert the appliance to natural gas. If you find the replacement orfice then you will need to remove the lp orfice from the burner and install the natural one. Then the appliance gas regulator will need to have the pressure adjusted lower for natural gas. There is usually a removable cap on top of the regulator on the oven. When you remove this cap there is usually a small metal ring that you can remove and flip over. It will say "nat" on one side and "lp" on the other. You will need to turn this ring over and re-insert so it displays "nat". This will change the gas pressure from 13 inches W.C. to 4 inches W.C. Some appliances only require the orfice change and no regulator adjustment but make sure that is the case with your oven because if you feed 13 inches W.C. pressure to a burner with a natural gas orfice...YOU WILL GET A HUGE BURNER FLAME AND MAY BURN/FLASH YOURSELF...So use extreme caution when converting a gas appliance. And if the oven has a pilot you will need to adjust the pilot pressure or change it's orfice if it has one. If it is electronic ignition no adjustment to that will be needed. Also unplug the electrical power the the unit while working on it.

Switch a natural gas furnace over to lp


WW Granger is the biggest supplier I know of for dayton. Consult them for information and if its still available. 
In lue of this find the oldest repair man you trust and ask him if he knowes anything about them. I know I could help if I could see what you have and had some more questions answered. Pilot ignition? Gas valve model? Does it have a regulator in the gas valve? Then you have to find a kit to block open the regulator. Then change the orfices to correct size or solder and redrill the old ones. Then maybe adjust the combustion air, and you may have to change the pilot burner orfice and adjust it. 
After that you can fill the LP tank.
Hope this helps IF so please grade me accordingly and Good Luck.

Converting your Natural Gas Dryer to Lp is taking it from a lower BTU gas "Natural" to a higher BTU "LP" value. The orfice on a LP gas valve is smaller because you dont need as much gas to make the same amount of heat. make sure you change the orifice. The little plug goes in the regulator of the gas valve, changing the valve from a low gas pressure Natural to a Higher Pressure LP.

If the kit doesnt look right, did you get the correct one?

Maybe you should call you LP provider they can do the conversion for you.
