Testing & Adjustments
Testing: Function - Magnet Coil - SIT 820 Nova Valve
Since the resistance of the magnet coil is too low to be read by most meters (0.015 milliohms),
a “hold-in” test is more practical. Connect one millivolt meter lead to the thermocouple capil-
lary tube. The other lead should be connected to the solder button on the bottom of the valve.
Light the pilot and hold in the on/pilot/off knob until your multimeter registers the proper amount
of millivolts to keep the pilot burning (6 millivolts for regular product, 4.2 millivolts for vent-free
product).
At this point, the knob is released and the pilot should continue to burn. If it does not continue
to burn, the valve fails the test and should be replaced.
