Converting gas to propane

[patty sipe]

anyone know what might be needed to convert a chambers to propane?

Copper Fan, from your other post, your stove looks like a '50s vintage Model C. If so, the conversion is fairly easy.

But from what I can tell (I'm in the process of doing the same thing), they're all slightly different depending on the year of manufacture, and even then, it seems the parts weren't always the same or may have been changed during the life of the stove.

So, if you get the manual and figure out what exact set up you have (type of mixer valve, orifice size, etc.), then folks in the group can tell you where to go next.

Meanwhile, you might search this newsgroup with something like "propane conversion". There're a number of threads on the topic including one from me a month or so back that has a photo.

Good luck,

Jack

The Simple thing to do is try to adjust the gas
air mixture with the valves that you have.
Propane burns hotter than natural gas so you need
less propane and more air than natural gas.
The Mixer valves may be adjustable for propane gas
from the factory. Where the mixer nozzle goes into
the burner there is a cap over the end. Tighten the
cap to lessen the amount of gas going through the nozzle. Some on the 61C & 90C models have a type
that is correct when the nozzel is screwed tight.
You are looking for a soft blue flame with no yellow
approximately 1/2 inch long. Work with one of the
front burners and just see if you can adjust it out.
The Air adjustment is made by a screw on the top
of the burner right next to where the gas enters
the burner. The screw allows a washer on the bottom of the burner to open or close to allow more or less air to mix with the gas.
Try one to see if you can adjust it out if not
you will have to go to plan B changing out the
mixer pins.
