I installed a Hayward H400FDN natural gas heaters. No codes when truned on. Cycles on and lites for 3-5 seconds, then poof. Recycles and tries again and same thing happens. Finally shows IF code (Ignition failure error). Need some help troubleshooting from here. This is a brand new unit. Thanks.
I had the same issue...you don't have enough gas pressure.
I do have enough gas pressure, but it still goes to IF for no reason..There has been no rain since I had it installed by a local pool company last Wednesday (Feb. 23rd) and it goes to IF right after it starts heating..I called the company and nobody responds..They are called everything 4 pools.....$ 2,500.00 for nothing as far as I'm concerned...
I had to.have the gas company come out and upgrade my entire meter (2lbs)...then I had to install regulators for my furniss, water heater, dryer, gas fireplace and the pool heater... after that... with some fine tuning...it worked.
