i have installed a Hayward H100iD1 Propane pool heater, but it's not firing up. the fan is not starting and it wont ignite. I have it connected to two 100 Lbs. propane tanks with a regulator that has an outlet pressure of 11"WC and has a 160,000 BTU/hr capacity. I checked for Leakes and its connected to a 20 amp gfci outlet. all seems in order, but like i mentioned above, wont ignite. I did follow all the operating instructions that came with the unit. Please advise any suggestions. Thanks

If the fan isn't starting then you have an issue with maybe the pressure switch possibly or one of the other safeties.
