Question about Hayward H Series Pool & Spa Heater 400k Btu Propane Gas Milivolt Ignition H400p1
All my connections look good, when i turn ignition switch on, heater does not light or come on, What should I check for? Do these heaters have a pilot light i need to relight?
Especially if this is the first time the heater has been used in a while you may need to call a sevice tech. I just had a H400 that did exactly what yo described. I had to shut off the gas, pull the burner tray, remove all the soot and debris, remove the burners from the burner tray and soak in a 3 parts water one part muriatic acid solution for about 10-15 minutes, also check the gap on the pilot ignitor if the gap is too small or too wide you will not generate a spark, also check the orifices on the gas manifold mine were wull of spider webs. after reassembly the heater went on and has worked fine since
