My brother purchased a Garland stove at an auction. The model is H-286. We do not have an instruction book on this stove. It is currently set up for propane and we need to have it changed so it can work on natural gas. Also, wondering if the rectangular shaped knob marked oven on the front is used to turn the gas on in the oven. Any information anyone can give us would be appreciated or if anyone knows where we can find a booklet on it.
