Laars Lite 2 Works but seems to be boiling in the heater!
My heater lites but seems to be boiling within a couple of minutes. The water flow through the heater seems okay and the filter system on the pool is working well with a good flow. Any idea why the water would be boiling in the heater?

First off they are not suppose to be installing a boiler that is not CSA approved. Your best bet is to contact Laars find out the real truth. I do know Laars was bought out by another company a few years ago, but the Installation company needs to stand by their product and be held accountable.
If unit is not request a new boiler or threaten talking to better business bureau Customers have rights. It also can be a liability to them.
cycling usually begins as the result of poor water flow caised by debris in the pump, dirty filter or low water level. once you have had some cycling the heater burners and ignitor become sooted and this requires pulling the burner tray, de-sooting the burners and pilot and reassembly. unless you are very competent you may want to call a service tech. Pool heater repair is a high laibility endeavor if done improperly. During the certification class our instructor showed us several houses that were burned down from improper heater repair.
turn power off first. I would disconnect igniter wire which will be a thick orange wire that comes off of ignition module if it is spark. once you have that the end will look like a spark plug wire take shield away from metal then hold orange wire in hand close but not touching metal turn power on and it will take a couple of minutes before it should start sparking. If you don't see a spark then it is most likely the ignition module. There should be a red light on ignition module that will blink to tell you what the failure is if is is a newer on. When you turn power on to laars light 2 the inducer motor should come on then a pressure switch should send 24volt to gas valve for pilot to lite.Can you smell gas at all when laars should be igniting. If you have any questions fell free to email me back
the control module is the problem it allows the heater to come on then turns off power to the gas valve.if you are not getting enough water flow the high limit is turning the heater off then your problem is flow.
