I want to install the Hayward Lownox heater on my pool but I live in the mountains at 3,000 foot elevation; do I need to buy a special high elevation heater?

Hello George, The Hayward Universal Low Nox are self adjusting up to 10,000 feet of elevation. Any installation above 2,000 feet will require a special restriction plate to be installed. Luckily, that plate comes standard with every heater so no need to purchase it separately.

Hi Jim the image here shows the exact Dimensions of the Hayward H200FDP Heater. I do not have the exact dimensions for the Hayward H200P1 heater but you should be able to match the location of the plumbing ports H200FDP to your H200P1 plumbing ports to see if you will have any slight re-plumbing. The H200FDP has 2" x 2-1/2" unions meaning that the heater accomodates 2" or 2-1/2" plumbing, if you have 1-1/2" plumbing that will be fine but you will just need to buy a standard 1-1/2" reducer.

I spoke to the technicians at Hayward ( 908-355-7995 ) and was told that the line into the valve was 3/4". The size of the tube up to that connection point, however, depends on how far the line has to run from the supply to the heater itself. This would be determined by the licensed installer.

Hi, Wagdy. That is correct. It cannot be repaired, you will have to replace the Heat Exchanger - FDXLHXA1200
