I recently had some work done to my house which required the installation of a new gas line to the house and a new section of the gas line to the pool heater. Now my heater won't start. I have a Teledyne/Laars Series 1 with electronic ignition. I called my pool guy and he thought it was because there was air in the gas line to the heater and I need to bleed the line. As it has electronic ignition, I am unsure on how to bleed the line. Any advice on this?
