I have a problem with a brand new propane gas mobile home water heater that is in a closet inside with about a 3" vent pipe coming up thru the floor that was fixed to the bottom of the old heater with a collar.
I lit it then and it worked ok but when I got home after work the water was cold and the pilot was out. I lit it again easily on the first click and it heated to the 120 mark I set it at.
Next morning it was out again, recurring problem.
I wonder if there is too much air coming in the vent and blew the pilot out or if there is a setting issue with it.
It's a US Craftmaster sold at Lowes, Model MFG1F4040T3PV7K.
It has a draft hood on top that I had to bend the feet down on so it would fit under the top vent pipe, there is 1/2" or more of space between the top of the heater and the draft hood to allow air to come in.
When the burner fires up it's pretty loud, louder than it should be in my opinion.
Any ideas? Thanks! John
