Hi. We just bought this stove (love it in general) and had it professionally installed running LP. It's been cool so we've been running it steadily downstairs to heat the whole house. Periodically, however, it just shuts itself off (usually after 4 or 5 hours.) I am not using the thermostat on the remote... just on via remote. I switched to continuous on pilot to see if the pilot stays on when the burner goes off and it does so I assume there is no gas interruption issue plus everything hot in the house uses propane with no problems. Is there some kind of safety that shuts this thing off after a certain amount of time in case you forget about it? I see no documentation on that if there is. Any ideas. The unit is brand new. Thanks for any suggestions.
