Hayward H100ID Propane. Ignites occasionally, but doesn’t stay lit.
Has worked for ~1 year no big problems, just the usual annoyances.
All switches/safeties are functional, and not jumpered.
Heater correctly spins up fan and calls for heat.
Propane begins supplying. However, ignition does not occur.
Ignitor is sparking. I have pulled the ignitor, and verified spark, as well as cleaned off white deposits.
I have pulled the burner tray; cleaned a tiny cobweb from one orifice. There is some cruft in the heater box, but not an enormous amount. The burners are clean; I didn’t pressure them out with a hose, but did seal the entry and blow through them and they seemed fine.
Input gas pressure is ~9â€Wc.
Output gas pressure is low; 1†WC.
I removed the dust cover on the adjuster cap. Turning the needle valve adjustment, however, seemed to make no difference. One oddity: backing the screw OUT (left) seemed to shut the valve: gas dropped to .25†and was intermittent and gas smell was faint. Turning the scren IN (right) seemed to increase gas flow, but I couldn’t get it past 1†no matter how far dialed in it was.
Initial setting was 3 ½ full turns out from bottom, and I have returned it to that.
Heater ignites occasionally, but doesn’t stay lit.
Love a sanity check/ideas on this one. Thanks!
