Accessing Fryers for Servicing

Before performing any maintenance on your Frymaster fryer, shut off the gas supply to the unit and disconnect the
fryer from the electrical power supply. Remove any attached restraining devices
Moving a fryer filled with oil may cause spilling or splattering of the hot liquid. Follow the Drain to
Pan instructions in Chapter 2 of the FQ4000-120 Controller Operation Manual before attempting to
relocate a fryer for servicing.
1. Shut off the gas supply to the unit. Unplug the power cords. Disconnect the unit from the gas supply.

Checking the Burner Manifold Gas Pressure

1. On non-CE fryers only ensure that the gas valve knob is in the OFF position (see
Figure 1A).
2. Remove the pressure tap plug from the gas valve assembly (see Figure 1B).
3. Insert the fitting for a gas pressure-measuring device into the pressure tap
hole.
On non-CE fryers only, place the gas valve in the ON position
4.
5. Place the fryer power switch in the ON position. When the burner has lit and
burned steadily for at least one minute, compare the gas pressure reading to
the pressure for the corresponding gas in the appropriate table on the
following page. The tables on the following page list the burner manifold gas
pressures for each of the gas types that can be used with this equipment.
6. To adjust the burner gas pressure, remove the cap from the gas valve
regulator and adjust to the correct pressure.
7. Place the fryer power switch (and the gas valve in non-CE fryers) in the OFF position. Remove the fitting from the
pressure tap hole and reinstall the pressure tap plug.
