Question about Hayward 250kbtu Ng Pool Heater - Inground
I have a hayward h250 heater. the pool water temp was 80 but the heater was so hot it was melting wires and melting the labels on the cabinet
That condition is from rollout of the burner flames. Check the underside of the heater top for a buildup of debris. Clean it if necessary. You may notice your heat echanger looks like a BBQ pit. If so it is sooted over and needs to be thoughouly cleaned before further use.
If you find this condition, you should also look at your burner tubes once the exchanger is cleaned and the heater is operating. Be sure the flames are nice and blue and 3 or 4 inches tall. If they are not, and especially if they are mostly yellow/orange, you need to do some more inspecting for what is messing up your combustion, which would have led to the soot.
Finally, if none of the previously mentioned conditions exist, consider wind pressure over the top of the heater. In windy areas and in certain installation conditions, you may needa high wind stack to provide positive drafting of exaust gas.
