How do I know if this heater is setup for natural gas or propane?
My grandfather passed away earlier this year. A few years ago he converted a Dearborn heater to use propane and had it out in his garage.
It's starting to get cold down here and we'd like to get the gas turned on and use a gas heater in the house. There's two of them, one set up in his old bedroom and one kind of taken apart and in the garage. It's no where near the propane tank and my mom said that's the one he had in his house. He did have one in the den, and the one in the garage is the only other one on the property.
I just want to make sure it has the correct orifice to use. Will I just not be able to connect it using the hose or is it something I won't find out until we try to light it?

If you can get a good look at the orifice,look at the hole size.Natural has a hole that is usually around the size of the tip of a pen,while lp is smaller.There also should be a number on the orifice.This will tell you the orifice size which you can either compare to the other one(if you know what type of gas it uses).To be sure of the correct orifice,call the manufacturer and ask what size they use for lp and natural,that way there is no guessing.Btw just sniffing to see what has been used doesnt mean the correct gas was used,just trying can have bad results if its set up for nat and you use lp.

You cannot te unless you are sure you know what you are looking at. If they have a regulator on them you might see a piece on it that says PRO or NAT that is one way.
It might be a good idea to have a furnace guy look at this for you to avoid any trouble you could cause to your self or the house in this case.
They all vary but the or orifices have to be adjusted or changed to either propane or Natural gas and the regulators have to be set and also to this.
Propane does need a regulator and if it is not connected in any way it may take some one with the knowledge of the proper code to do this.(Right size tubing, right kind and so forth)

Either have the gas company come out and look at it or take the valve where the gas first comes out of the unit to a shop that would well them - compare the size of the hole because this is what determines whether it's gas or propane (as far as Iiknow).

The easiest way is to loosen the fitting that goes into the furnace and sniff. Propane and Natural gas smell nothing alike. If it is already hooked up then it should've had all the conversion parts changed over. Try it and see. Nothing bad will happen it just won't operate correctly.

Yes, providing the burner jets are changed to suit the gas. Not all appliances can be converted. You will have to check with the maker and it should be done by a gas engineer.
