Question about Pool & Spa

Open Question

I am looking to replace an XL-2 Teledyne Laars oil fired swimming pool heater but they seem to be obsolete. Many dealers have discontinued this model{DP-250 and DP-350} I note that some people carry the XL-3 which looks similar. Would a XL-3 fit the existing piping arrangement. If so who can do this job? The pool is in the town of Jefferson New Jersey on Lake Hopatcong lakefront Bob Ahart

SOURCE: Laars Teledyne Pool heater flames on for 2 seconds, shuts off

You have no flame rectification.....LLD series heaters check for a signal through the flame to ground; if the module does not detect this signal, it go through two more trials for ignition and then lock out the module. There should be a flame rod and it may need cleaning. I use steel wool.

I wish I could tell you a part number and a supplier but I can only recommend contacting your propane company or a licensed LP Gas plumber. Either one will need to know pool heater information. I hope this helps.
