Not sure about your specific heater, but if the heat won't go on, it could be the water pressure sensor or one of the temperature sensors.

Do you mean the gas? There is no fan.
The first time when we turned this on, we needed to shut everything off (except for the gas) including the power at the breaker. There is an internal safety device that needs to be reset before it will operate. Then turn it all back on in this order, the breaker, then the unit. That worked for us when we were having an issue with the unit.

To convert the heater to natural gas you will need to change the orifices in the gas unit to natural gas. I am assuming you now have it on LP gas. Hope this helps. You should have someone who knows to change the orifices over. Most appliance parts dealer carry them.
