Facts: Greenhouse is 20’ x 60’ or 1,200 square feet, 12’ high.
Have tried three brand-new un-vented propane heaters. (two different models)
Symptoms: They light and burn, but about midnight are found to be out—perhaps after working about four hours. It seems the unit runs okay, but after a while the pilot begins to flickers and is eventually sucked out when starting on the next cycle. When try to relight the unit it won’t light until the next day after the door is opened to the greenhouse and it is aired out. A butane lighter (used to light charcoal grills) and the lighter with a flexible hose used by the technician wouldn’t light in the area either.
Thought it might be elevation problem (I live at 4,600’), but the last unit I bought is supposed to work to 5,500’. It seems to be some environmental problem.
I put a two-inch flexible hose from the outside to come in under the heater for fresh air…butane lighter lights in front of pipe...not in room. HELP!
