Question about Hayward Pool & Spa
Not much info to go by here Patty.
A gas fired heater needs spark and fuel to ignite. We need to start by to determining which is missing.
The H series has seen a few progressions. Does yours have no lights, 3 lights, or a lcd display? Propane or natural gas? Standing pilot or spark ignition?
Do any lights or display come on? Do you hear any clicking?

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

AO will apply to your blower, blower tubing, or blower vacuum switch. You need to check these items.

You didn't say what terminals you jumped, but I assume it's the flow switch, or it could be the thermostat. The flow switch is located on the piping inside the heater. This flow switch is very important because if you didn't have water flowing through the heater it would oveheat. These do go bad or sometimes just get stuck depending on what type they are. If it's the thermostat, mounted on the front pane you're jumping, then either it or it's expansion bulb is faulty. GOOD LUCK Who needs a heater in JULY?
