5.3 ORIFICES AND BURNER VENTURI
Burner orifices can collect dust and grease
over time in any kitchen environment. If this
material blocks the orifices, the appliance will
be less efficient and can cause intermittent
operation or complete shutdown.
Depending on the size of your appliance,
there are a minimum of 2 and a maximum of
3 orifices that require inspection and cleaning.
Each burner will have an orifice.
Required Material: towel, soap and warm wa-
ter, stiff wire smaller than the orifice nozzle or
orifice drill of the same size hole.
Tasks:
1. Remove the orifice
2. Dampen a towel with the soap and water
solution and clean the orifice.
3. Take the stiff wire or orifice drill and insert
it into the hole in the center of the orifice
and run it back and forth, making sure all
foreign material is removed.
4. Reinstall the orifice.
5. Clean the burner venturi opening so that
it is free of any collected dust, grease and
any other foreign material.

5.4 GAS PRESSURE
The appliance requires the proper gas
pressure setting to operate properly. All
pressure readings should be taken after the
unit has reached a temperature of at least
200°F and while it is running to ensure proper
flow rates.
Required Material: Manometer with test hoses,
1/8" NPT barbed hose fitting.
Tasks:
1. Verify the pressure regulator vent is clear
before making any pressure adjustments.
Remove the 1/8" NPT pipe plug from the
main gas valve and install the 1/8" NPT
barbed hose fitting. Tighten and mount
one length of the rubber hose.
2. Allow the appliance to heat up to at
least 200°F. First, check the main burner
regulator pressure. Remove the rubber
hose and replace with the manometer
tube. The pressure should be 5" WC for
natural gas and 10"WC for propane. If the
pressure does not meet or exceeds these
values, remove the cap on the main burner
pressure regulator and adjust it to the
necessary value.
3. Replace the hose fittings with original pipe
plugs.
4. Check for gas leaks.
