Review this - should be similar. Bottom line is it probably won't be optomized, no flame at the low end or too hot at the top end (use caution): http://www.komar.org/bbq/mm/convert/dannos.html
Yes, Propane burns hotter.
you don't
Change out the gas flow orifice size to propane and adjust the gas valve.
Yes, though you may have to change the orifice to accommodate propane rather than the natural gas.
I want to change a dearborn space heater mod # drc12b1lp from natural gas to propaine how do i replace it & what do i need .thanks
http://okeefe-merritt.com/pages/parts/partso%27keefe.html Go to this website and look for a propane to natural gas regulator. They sell them for $42.50.
You can just refill the propane tank. It is more difficult to do something like change a gas generator to a propane generator.
Get a certified technician to work on gas. He will have to change the orifice, possibly the gas valve.
Unless you are extremely knowledgeable about gas devices, you shouldn't fiddle with them.
If you use a high amount of natural than it is less $ then propane BUT if you use a moderate amount or less than no doubt propane is less. The reason why is even if you do not use any natural gas you still get charged a service fee and tax tax each month, where propane you do not have the extra fees. other than this factor it is almost not possible to figure what is cheaper since the prices for both change rapidly and propane heat is more hot burning. so thus makes it very very hard to figure it out.
In the United States their is only Natural Gas and Propane Gas. If you don't have a Propane Tank in your yard you have Natural Gas. If you have a propane gas furnace and want to change it to a Natural Gas furnace you have to have a heating/ac guy do it or you could burn your house down. The change in pilot size is directly proportional to the btu output of your furnace and is custom sized for each different make and model (1000's of different models in the US)
You change the orifice in the burner. Propane and natural gas require different orifice sizes. You should check with your gas or propane supplier, or contact the manufacturer for more detailed information. If you have good information and are a pretty handy individual, you might be able to do the conversion yourself. But, be warned, if you make a mistake, if could be tragic.
