I believe I have the same stove in like new condition i purchased at an auction a year ago. I need to locate a manual for it but so far cannot. Mine has a large round tank that sits on the back of stove, two burners inside with tank coverings, the model #685800R and the #974 is on a metal plate on the back of the stove. It is brown with vent slits on both sides and has a square door on the front. Do you have an owners manual with yours?

Hi, I have a Montgomery Ward Sunheat heater. It's a dual burner enclosed type with a door on the front. The fuel tank is cylindrical and about 1 1/2 - 2 gallons. The cap has a needle valve and when turned upside down releases fuel to the burners by gravity. The whole heater itself is rectangular with louvers on the sides and top. I don't know what wicks go in this or if there are compatible replacements out there.
No 84ALO5800A is the only I.D. or Model No.
Thanks,
Jack
