This is a computer board for the 40H-LP (outdoor mount, liquid propane). All wire connections fit into this board. It is the main programming source of your water heater.

This is the first on demand water heater we have owned. We were buying 700-900 gal. of Propane a year. After installing the 40H it cut our bill in half. We had a computer board problem and notified the company as our unit is still under warrenty. The company shipped out a new board. I installed it upon receipt and we are back in hot water. I would recomend one of these units to anyone who wants to cut there propane bill.
