A leak limiter is supplied with every regulator to limit gas leakage if regulator rupture occurs. Do not
obstruct leak limiter on gas pressure regulator as obstruction may cause regulator to malfunction.
Tools Required: Manometer, flat blade screwdriver, 6" adjustable wrench, slip joint plier or pipe wrench.
1.
Connect the manometer to the pressure tap provided on the manifold pipe near the regulator (Fig. 9).
Fig. 9
2. With only two open top burners ON, note the manometer reading. The reading should be 3.7" Water
Column for natural gas ranges and 10.0" Water Column for propane gas ranges. If readings taken
are lower, check the incoming line pressure. The line pressure should never drop below 5.0" Water
Column for natural gas or 11.0" Water Column for propane gas.
If line pressure is incorrect, it must be adjusted in order to properly operate the range. If the line
pressure is good, then the regulator requires adjustment (refer to procedures for regulator
adjustment).
If, after the regulator adjustment has been made, the 3.7" Water Column (natural gas) or 10.0"
Water Column (propane gas) still is not being maintained, replace the regulator.
3. With the regulator now reading 3.7" Water Column (natural gas) or 10.0" Water Column (propane
gas), turn two open top burners ON.
4. Recheck the pressure reading. The reading should not fluctuate more than ± .10". If reading is not
within tolerance, replace the regulator.
When the burners are OFF, if the pressure reading climbs to an outlet regulator pressure stated in Step
2, check the regulator vent for obstruction (Fig's. 10 & 11).
