I tried to start up the Cat Heater in my 1963
Bambi, when I push in the pilot button and place a flame in the pilot hole, every burner lights up. When I let go, it all went out, including the pilot. so I tried it again but this time after it all lit up, I held the pilot button to get the thermocouple heated up and let go and it stayed on but for only a minuet or two. Then it all whet out.
I have no idea who the manufacture is but I do know it is the original, any help would be great.
