Hayward H Series 400,000 BTU Pool Heater Won't Ignite
IF code appears, heater starts up and shuts off after two seconds; Can I try lighting manually, to get it going just for today, and if so, how do you light it manually?

You can not manually light it. Open the front cover look for the gas nozzles brass looking on a tube. on the right side you will see a wire going to a sensor above the next to last burner take the nozzle out for that burner. 7/16 wrench unsrcew the nozzle and see if it is clogged. use something soft to push it out. Spiders love to lay eggs in these. Spray with WD40 and reassemble should work now
Best of luck
BRILLIANT! 6 out of 8 of my jets were clogged with that white spider discharge. Took each one out, cleaned them, WD40'd them, reinstalled them... and WHOOOPH! Fired right up! I wish I knew how much $ you just saved me!!! (took pics - if anyone wants 'em, message me. THANKS AGAIN!
Hayward Pool Heater won't light?
Clean the gas jets of white spider guck! After shutting the gas off, loosen the two front cover screws and remove it, use a 7/16 wrench to unscrew each jet (8 on mine), clean it out with a pipe cleaner something similar, WD40 it, and reinstall.
IF is ignition failure,
and no you cannot light an electronic heater manually, there is no standing pilot.
check gas orifices for blockage, if not tou may need to replace HSI
