I dont know about your particular model. I do manage two Hayward 380,000 pool heaters that are natural gas fired and I have never had this problem you describe.

I also manage another dozen or so assorted other gas and propane devides. One propane device sooted so bad we had to discard it. It did this, according to the propane tech, because it couldn't breathe - there were louver type vents on the door that leads directly outside. He did, however, find a ruptured diaphram in the regulator and he replaced it. Hmmmmmm, couldn't breathe eh????

I'm not too surprised at the repair cost you cite. The exchanger is of course copper and there is the labor involved and lots of it. The age of your unit at this point is not relavent. What you do need to determine is why the unit sooted up like this. If you are gas fired, you know this is considered a clean fuel (compared to all others except electricity). What ever caused it must be repaired or you will be looking at another sooted up problem and repair ... and it will not be in three years, it could be next week.

I hope you find some value to my comments . Thanks for posting this question at FixYa.com

SOURCE: My heater ignites and blows really hot exhaust

The water is mixed on the back side of the heater and will exit the heater at 7-11 degres hotter than it came in. This will keep people from being scalded at pool side. So what you have sounds normal.

SOURCE: What does the service symbol 1F referring to?

It means Ignition Failure. They heater went thru its startup cycle, and when the gas valve opened, the heater did not sense a flame. The whole routine begins again. After about 3 attempts at this, the heater will flash IF and then go into a lockout situation. This is a safety feature of this heater.
