Convert a procom heater from propane to natural

the gas company has to come change the regulator for you

yo have to get a kit the orifices are way different because nat gas runs at one half a pound and propane runa at 10 pounds

Found the manual on line and copied directly from it:
WARNING
Models FBN400 are equipped for Natural
gas. Field conversion is not
permitted.
Models FBL400 are equipped for Propane
gas. Field conversion is not permitted

This should answer your question.
See if you can run the gas line or find someone to do it cheaper for you.

check with ur local propane service most have their own service team they should be able to tell you who and or how to do the conversion

You can't. You need an LP gas valve which costs almost as much as a new unit. Pressures are different and orifices need to be changed, the the pressure needs to be reset. Just buy a new unit and be safe.

HI , I HAVE A PROPANE MODLE QL300TYLA I WOULD LIKE TO CONVERT TO NATURAL GAS , MAYBE WE CAN SWITCH PARTS.

search web for manufacturer.more than likely your vent free unit is not convertible.

You need to first get a regulator which will go between the propane tank and the burner. You will need to know the burner capacity in BTU/HR and the pressure required. All of this can be found on the furnace specification plate or on the gas valve. It is a no brainer Circut!

I have a similar problem. But, I want to convert it to propane. I have a 5 burner vent free modelMN300HPA. If your are handy. I would consider shipping you the parts inside mine to install in yours. These parts are very simple to remove after removing the access panels. I have taken mine out already. Called procom then to no less find out the propane parts needed are not sold by them. I think only the injectors (5) the main valve (regulator) and the pilot are the only things need to change. When taking out the pilot this is easly done, By removing the nut on the supply line. And then bending back the retaining tabs to then slide back the pilot then it comes out of the assembly bracket. Injectors are simply removed. Regulator located at the bottom is a simple remove. The only other item that might be questionable would be the valve that selects the amount of burners you would like to operate. And I would think this would be the same and not need removing. Let me know if I can help. I would like to get mine converted to propane. Thanks Tom

first you gotto see IF a changeover is possible! do your instruction manuals say it can be converted?
