2-8 Gas Pressure Regulator Setting The gas pressure regulator on the gas control valve is
factory set as follows:
Natural: 3.5 inches water column (0.87 kPa)
Propane: 10.0 inches water column (2.49 kPa)
The gas pressure regulator has been set by Henny
Penny and is not to be adjusted by the user.
MAKE SURE GAS PRESSURE IS SET CORRECTLY.
FAILURE TO DO SO CAN RESULT IN
SHORTENING OVERFLOWING THE FRYPOT,
WHICH COULD CAUSE SERIOUS BURNS,
PERSONAL INJURY, FIRE, AND/OR PROPERTY
DAMAGE.
Measuring Gas Pressure
1. Locate the pressure tap hole or fitting on the
side of the gas valve. Remove the pipe plug
from the valve or fitting circled in Figure 1.
Figure 1. 2. Screw a pressure tap fitting into the valve or
the fitting on the side of the valve circled in
Figure 2.
3. Place one end of a vacuum hose on the
pressure tap fitting and the other end on the
manometer as shown in Figure 3.
4.
Turn the fryer “ON”.
5.
Allow the fryer to reach full burn.
6. The pressure reading on the manometer
should be 3.5” of water column for Natural
gas and 10” of water column for LP gas.
Figure 2. 7.
Turn the fryer off.
8.
Remove the pressure tap fitting.
9. Place the pipe plug back into the valve or the
fitting on the valve.
