Allsafety switches are monitored by theignition control IgnitionSolid state electronic spark igniterprovides positive direct ignition ofburners on each operating cycle. Thesystem permits main gas valve to stayopen only when the burners are provento be lit. Should a loss of flame occur, thegas valve closes, shutting off the gas tothe burners. Ignition module has LED toindicate status and aid circuit on moduleautomatically resets ignition controlsafter one hour of continuous thermostatdemand after unit lockout, eliminatingnuisance service calls.
