it makes sure the heater is shut down BEFORE the pump does. It is very important if the heater runs without the pump running the water will boil in the lines and burn out the heater. I know this because my electrician didnt wire mine correctly and that's what happened to me. BYE BYE 2,500 heater
I cannot find a current listing for Teledyne Laars. As far as I can tell, Teledyne and Laars separated, Laars joined up with Waterpik and then got reorganized under Jandy. www.jandy.com now has the Laars Lite2 line of pool heaters with the LG model almost identical to the Teledyne Laars LLG. You can access the manual at http://www.jandy.com/pdfs/H02359-.pdf . Jandy also has a parts list for older discontinued models.
Bypassing the pressure switch on a Teledyne Laars pool heater is not recommended, as it can pose safety risks and lead to equipment damage. The pressure switch is a critical safety feature designed to prevent the heater from operating under unsafe conditions. If you suspect an issue with the pressure switch, it's best to troubleshoot the problem or consult a qualified technician for repairs instead of bypassing the switch. Always prioritize safety and proper functioning of your equipment.

The BTU output of a Teledyne Laars Series 2 residential heater can vary depending on the specific model. Generally, these heaters have capacities ranging from about 30,000 to 150,000 BTUs per hour. For precise specifications, it is best to refer to the product manual or manufacturer's documentation for the exact model in question.
Use the manual provided with the heater. Each heater has somewhat different controls etc. If everything is already hooked up you may just have to turn a switch or two and turn up the thermostat.
Possible reasons why a Teledyne Laars Phase 2 pool heater may not ignite include issues with the pilot light, gas supply, or faulty igniter. Check if the pilot light is lit, ensure there is proper gas supply to the heater, and inspect the igniter for any signs of damage or malfunction. Additionally, check for any error codes on the heater display panel that may provide further information on the issue.
