3.4.6 OPERATING INSTRUCTIONS

3.4.6.1 FAN LIMIT CONTROL

The fan limit control settings may need to be adjusted depending on the
installation, but they are set at 100 °F (Fan OFF) and 250 °F (Fan ON) at the
factory and these settings will work best in most installations.
It is preferable that the setting "Fan OFF" is low enough to avoid too frequent
stopping of the fan, but setting "Fan OFF" too low will result in cold air circulation,
which is undesirable. To change these settings, turn the indicator to the desired
position on the temperature scale of the fan limit control.
For continuous operation of the blower, use the switch located below the fan limit
control which controls the low speed either at the "ON" position or the "OFF"
position. It is not recommended to let the blower run on continuous mode when
heating with wood since the wood furnace must reach a certain temperature
before the blower starts in order to operate efficiently.

3.4.6.2 COMBUSTION SAFETY CONTROL

The AFG type oil burner is equipped with an electronic control (# R7184B1032)
including a pre-purge function and a new, more durable drive motor.

3.4.6.3 PRE-PURGE

When there is a call for heat, the burner's fan will run for 15 seconds before the
actual ignition takes place to vent the combustion chamber and generate a
proper draft. This will result in a smoother ignition of the oil burner.

3.4.6.4 SAFE OPERATION

If the flame goes out while the burner is running, the control will then switch to
the "RECYCLE" mode and cut the fuel supply to the burner for 60 seconds. After
this delay, the control goes back to "IGNITION" mode. If the flame goes out 3
times in a row, the control will switch to the "LOCKOUT" mode to prevent a
continuous cycling of the ignition process, which would cause a premature soot-
up of the combustion chamber and smoke pipe. To deactivate the "LOCKOUT"
mode, press and hold the reset button of the control for 30 seconds.
