GAS PRESSURE REGULATOR
VALVE ADJUSTMENT
NOTE:
Before adjusting the regulator, check
incoming line pressure.
Figure 25: Gas Pressure Regulator – Typical
A. Adjusting Screw
B. Spring
C. Closing Nut
1.
Check the gas supply pressure according to
CHECK GAS SUPPLY PRESSURE.
2.
The manometer is already connected.
3.
Remove the regulator closing nut.
4.
Insert a straight-bladed screwdriver through
the top of the regulator. Turn the adjusting
screw clockwise to increase pressure and
counterclockwise to decrease pressure.
5.
While watching the manometer, turn the
adjusting screw for proper regulator outlet
pressure, typically 5.0" W.C. for natural gas
and 10.0" W.C. for propane.
Check for insufficient gas volume
6.
Fire up one burner and take a reading, then fire
up all burners on the range and take a reading.
7.
Fire up all the gas equipment on that supply line
and take a reading. At no time should pressure
drop more than 0.5" W.C. If pressure drop is
greater than 0.5" W.C., go to the next step.
8.
Turn off all the gas valves. Adjust the regulator
to no more than 0.5" W.C. above specifications,
which would be 5.5" W.C. for natural gas or
10.5" W.C. for propane.
9.
Repeat step 7.
If pressure drop is still greater than 0.5" W.C., there
may be a lack of volume due to too small of a supply
line. Advise the operator to check with the gas
provider about installing a larger size gas line.
10. Install the regulator closing nut, remove the
manometer, and reinstall the plug.
TOP BURNER PILOT LIGHT
ADJUSTMENT
Figure 26: Adjusting Top Burner Pilot Light
A. Pilot Adjustment Screw
Mushroom head type pilots are used on open
burners, griddles, and hot tops. The flame should
be only about the size of a dime. This type of pilot
will burn yellow, so flame should be as small as
possible and still be able to ignite the burner within
3 or 4 seconds.
To adjust the pilot flame height of the top burners:
1.
Locate the pilot adjustment screws found on
the front manifold pipe.
