Good morning all.
Since it is summer and I don't need my heater for a while I thought I would look into why my pool heater goes through multiple flame on / flame off sequences before finally staying on. I find when I start the heater, I can hear the spark, then flame on, and then after a few seconds the flame goes out. It can repeat this for dozens of times before running properly. I thought there would be some kind of flame sensor, but can not locate one nor do I see one listed on the schematics of the unit.
unit is a P-R405AL-EN from Raypak.
Thanks in advance for any help.
