2.2 Main Burner System Adjustment
For the main burners to operate the gas supply valve must be open and the thermostat must be turned on. For
models with electric controls, the main power switch must be on. The main burners receive gas from the main
gas supply through the thermostatically controlled valve. When the thermostat is turned up to a setting higher
than the temperature of the oil in the tank, the gas control valve opens.
The main burner pressure must be adjusted to deliver optimum flame. Refer to the following procedure to adjust
the main burners.
CAUTION
Before proceeding any further, fill the tank with WATER. Water is used for the installation
adjustments because the temperature will never exceed 212°F (100°C), thereby allowing plenty of
adjustment time. Never let the water level go below the MIN LEVEL mark stamped on the tank
.
a.
Ensure that the main gas valve is shut off; remove the manifold pressure tap plug and connect
an accurate pressure gauge having a range from 0 to 16 “ w.c. in 0.1” increments (0 to 4 kPa in
.025 kPa increments) or manometer with similar resolution.
b.
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.
c.
The installed pressure gauge should be the same, ±0.1”
w.c. (.025 kPa), as that marked on the data plate on the
inside door of the appliance. If the pressure is correct, go to
step e, if it is not, adjust the pressure as outlined in step d.
d.
To adjust the pressure, remove the regulator adjustment
screw cap on the gas valve 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.
e.
When the pressure is correct, replace the regulator adjustment screw cover.
f.
Turn off the ALL appliances, shut the main gas valve to your appliance and remove the
pressure gauge. Apply pipe joint compound to the manifold pressure tap plug and reinstall it.
2.3 Thermostat Calibration
Thermostat Calibration Check (Standard)
NOTICE
Thermostat calibration requires that the temperature of the appliance be raised above 212°F
(100°C). If you have water in the tank you will need to drain it, dry it and fill it with shortening/oil.
Follow the filling instructions in this manual.
To check the calibration of your appliance, refer to the following procedure.
a.
Remove the tube screen from the tank.
b.
Place the tip of a digital thermometer probe in the shortening/oil approximately one inch above
the temperature sensor.
c.
Light the pilot as described in this manual, set the thermostat to 325°F (163 °C) and allow the
shortening/oil to come up to temperature. Watch the thermometer closely as the temperature
rises.
d.
If the shortening/oil temperature reaches 350°F (167 °C) and the burners do not turn off, turn
the thermostat down. Keep lowering the thermostat setting until the burners go out.
e.
Let the appliance cycle 4 to 6 times before checking the temperature. Compare the
thermometer temperature against the thermostat setting. If the values are more than 5°F (3 °C)
apart, calibrate the thermostat using procedure in this manual.
