propane heater

Hi , I have a hayward heater for a above ground pool and it has been working great. I recently added a new 100lb tank and I cannot get the heater to fire up, I switch back to my old 40lb tank and no problems. Any help hear would be freat THANKS…Steve

Hi,

I would think that this has something to do with the gas pressure changing from the 40lb tank to the 100lb tank. I would take a look at page 3 & 4 of this Hayward Above Ground Pool Installation Manual for more details.
