INSTALLATION/OPERATION

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
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.
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 “OIL 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 (range of 0-16 “ w.c. in 0.1” increments) or
manometer.
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, as that marked on the data
plate on the inside door or on the back 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 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.
