PILOT FLAME ADJUSTMENT
Perform this procedure with the pilot lit.
Note: This procedure requires a DC millivolt meter set to a scale of 0-1000 mV. Using test leads
with sharp probes will help in taking the required readings. Using test leads with sharp probes
will help in taking the required readings
1.
Locate the thermopile wires coming from the pilot to the
gas valve.
2.
Connect the positive (+) test probe to the terminal with the
red wire. Then connect the negative (-) test probe to the
terminal with the white wire.
3.
Adjust the current reading to the required level by
adjusting the pilot flame. Remove the pilot adjustment cap
screw to expose the pilot adjustment screw. Turning the pilot
adjustment screw clockwise will decrease the size of the pilot
flame and flame sense current. Turning the pilot adjustment
screw counterclockwise will increase the pilot flame size and
the flame sense current.
4.
Turn the screw in or out as needed to achieve a reading
of 550 mV ± 50 mV.
Note: Allow 3 to 5 minutes between flame adjustments to
allow the reading to stabilize.
Once the pilot flame has been adjusted properly, remove
the Millivolt meter and replace the pilot adjustment cap
screw.
MAIN BURNER SYSTEM ADJUSTMENT
For the main burners to operate the gas supply valve must be
open and the thermostat must be turned ON. The main burners
receive gas from the main gas supply through the thermostatically
controlled valve. When the oil temperature drops below the preset
temperature the gas control valve opens.
The main burners must be adjusted to deliver optimum flame. Refer to the following procedure to adjust
the main burners.
1. Ensure that the main gas valve is shut OFF, remove the burner pressure tap plug and connect an
accurate pressure gauge (range of 0-16 “W.C. (39.85mbar, 3.98kPa) in 0.1” (.25mbar, .02kPa)
increments) or manometer.
2. Turn on this and all appliances connected to the gas supply line and
light their main burners. The pressure reading of the installed
pressure gauge should not drop from the required installation
pressure. Any loss of pressure indicates inadequate supply line
installation, which will cause poor performance of all appliances
during peak usage.
3. The installed pressure gauge should be the same, ±0.1” W.C.
(.25mbar, .02kPa), as that marked on the data plate on the inside
door of the appliance. If the pressure is correct, go to step 6, if it is
not, adjust the pressure as outlined in step 4. To adjust the pressure,
remove the pressure regulator cap screw and, with a flat head
screwdriver, adjust the regulator screw until the proper burner
pressure is reached. Turning the screw clockwise will increase the
burner pressure. Turning the screw counterclockwise will decrease
the burner pressure. When the pressure is correct, replace the
pressure regulator cap screw.
4. Turn OFF ALL appliances, shut the main gas valve to your Anets
appliance and remove the pressure gauge. Apply pipe joint
compound to the manifold pressure tap plug and reinstall it.
5. Check for leaks at the pressure tap fitting.
