Laars 2400-542 Flow Switch Teledyne Laars 2400-548 Gas Valve
This gas valve is for the Endurance EBP and EDP boilers, new style and old style.  A combination gas valve will work with both natural gas and liquid propane gas (LP) but both gas types must be set up by making adjustments to the air and gas mixtures utilizing a dual menometer and electronic combustion analyzer.  Parts4heating has several of these 2400-548 gas valves in stock and are ready to ship one to you today!

The igniter is a “glow bar” type silicon carbide unit. It is
energized whenever there is a call for heat and the red
"IGNITER" light on the boiler control is lit. After the igniter is
switched off and the boiler continues to run, the igniter functions
as a flame sensor for the boiler control.
If the ignitor fails and must be replaced, always install a new
igniter gasket with the replacement igniter.
CAUTION: Ignitor gets hot.
