The valve itself allows you to bypass the plunger by pushing
it in. This allows gas flow to the pilot, which then must be
ignited. The valve must be held depressed for approximately
30 seconds in order to sufficiently heat the thermocouple
and generate millivoltage. If the valve is not depressed for 30
seconds it shuts down the gas flow.
Once the pilot is lit and the millivolts have been generated,
the magnetic coil takes over and holds the valve open. If
there is no heat at the thermocouple, the valve will not stay
open. The same coil controls the burner flow, therefore, if
you have ignited the thermocouple and you’ve got the valve
to stay open, you can then go ahead and turn the burner on
and the pilot will light the burner.
The particular pilot used on most of our burners is a fishtail
design, which throws flames in two directions (one to ignite
the burner and the other to keep the thermocouple junction
hot). In between the pilot and the thermocouple is an
electrode, which can be used to spark ignite the pilot. This
can either be from a piezo igniter or from an electric spark.
All enclosed burners ignite in the high position and then
they have to be pushed into go to the low position. The
reason for this is to ensure no delay in ignition.
Burner Gas/Air Adjustments
Variations in field conditions, rough handling of the
equipment in transit may indicate the need for adjustment
of the primary air to the burners. Check the operation and
adjust as below to provide a sharp blue flame at the full
rate (open valve fully so that the thermostat is calling for
maximum gas flow).
1. On the burner (star, “H” griddle, broiler, oven burners)
locate the air shutter.
2. Loosen the lock nut so that the air shutter turns freely.
3. Reinstall the burner.
4. Turn on the gas flow and ignite the burner.
5. Rotate the air shutter to obtain the following:
Open (Star) burner
1/2” stable, sharp inner blue cones.
1/2"
Star Burner
Hot tops, griddles
5/16” stable sharp inner blue cones.
5/16"
Griddle "H" Burner - Side View
