Raypak not getting gas

[joecny]

Hi all.
I have a 1 year old Raypak (404A) that is not kicking on. The unit powers on, attempts to ignite 3x and then locks me out. The igniter is working properly. I don’t smell any gas whatsoever. I’m not sure if it’s a gas issue or a valve or something else. Banging my head against the wall since I didn’t have any issues when I closed to pool. Any advice would be greatly appreciated.

Welcome to TFP.

Do you hear the gas valve click open?

You have a multimeter? Check for 24V at the gas valve when the heater starts up.

Gas pressures at the gas valve should be checked with a manometer.

Just had same problem with mine.
I had to take the pilot supply line from the gas valve off and blow air thru it.
Had spiders or something in it
