Atwood Water Heater Will not Ignite or Stay Lit

1. Small flame indicates a clogged orifice. Remove the orifice and clean with spray carb cleaner and compressed air.
2. Also indicates LOW or marginal LP gas pressure. Light the Stove/Range burners all 3 or 4. They should have a full blue flame
3. When it tries to ignite, tap on the gas valve with a hammer. IF the flame then comes ON, your gas valve is bad.
4. If the W/H is in a slide room, then the rubber gas line may be pinched. Doug
