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.
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.

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.
Probably a bad sensor. Have a professional diagnose the problem. It can be very dangerous for untrained to work on gas appliances.
