Hello
I have friend who has a atwood 7916 II heater. It is in a camper and it didnt work at the begining of the season. He replaced the board and it did light and run but now a couple time a night it explodes and sends a ball of flames out side the camper.I have never seen it but i guess its a real sight. Any ideas?

Did he use a Dino board?

If so, it may be one of their universal boards that has a resistor that works like a 20 second delay. You would need to clip that resistor off the board. That makes it an instant ignition. If he still has instructions, it will tell him which one it is. Or contact Dinosaur and they will tell you.

Are you talking about a water heater or a furnace?

I talked to him some tonight and he said the unit runs fine when he first starts it. After it warmed up and it hoes to re-fire he hears the ingniter snaping then after several snaps mabee 8 or 10 times it fires with a bang. It sounds like he may have an igniter problem. I quess in talking to him this problem did exist before the board to some degree.

Skip,
The universal board can be used on either and you can eliminate the 20 second delay to be used in a waterheater.

Rich
As far as the furnace goes, check to make sure it is operating with the 20 second delay and not instant ignite.

Sounds like it needs a good cleaning.

Make sure the gap between the igniter and ground is correct.
