Check also for gas leak at vent. If vent is leaking gas, replace the regulator.

REGULATOR ADJUSTMENT

Tools Required: Flat blade screwdriver, manometer, and 6" adjustable wrench.
Before making a regulator adjustment, always verify that the incoming line pressure is correct. The
required incoming minimum line pressure for the modular range series is 5.0" Water Column for natural
gas and 11.0" Water Column for propane gas. If the line pressure is not correct, it must be corrected
or the range will not operate properly or achieve proper regulator adjustment. Also, the regulator must
be attached to the range in the horizontal position with the arrow pointing in the direction of the gas flow
(Fig. 12).
