Universal hot surface ignition module from Resideo (Honeywell Home), part number S8910U3000/U.

The ignition control runs the light-off sequence and holds the safety logic: purge, energise the igniter, open the gas, look for flame, and lock out if it does not find one. The trial-for-ignition period is how long it will let gas flow while waiting for proof of flame, and it is a safety figure, not a preference.

Universal means one module covers a range of hot surface applications, with the timings selected on the module rather than fixed in the part number. That is what makes it a truck stock item instead of an order-per-job part.

Gas appliance safety. A gas valve must match the appliance it is fitted to — ignition system, capacity, inlet pressure and gas type. Replacement is work for a licensed gas technician, and the appliance manufacturer's parts list is what decides the correct valve, not the physical fit of the threads. If the replacement does not match, the appliance can fail to light, fail to prove flame, or overfire.
