Combustion Safety Control - PSG -2000 Installation And Operating Instructions Manual

In order for the blower to run for long enough periods, the "fan off" setting must not be set too high but
too low a setting will result in undesirable cold air circulation. To modify the settings, move the tabs to the
desired position on the temperature scale of the fan limit control.
All adjustments of the controls must be performed by a qualified technician. The controls settings and the
blower speeds must be set in accordance with the recommendations of the Warm Air Heating and Air
Conditioning National Association.
To obtain a continuous air circulation during summer months, simply turn the manual switch "ON". The
summer switch is located on the controls junction box.
It is not recommended to let the blower run on continuous mode when heating with wood as the wood
furnace must reach a certain temperature before the blower starts to perform adequately.

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.
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.
SAFE OPERATION
If the flame goes out while the burner is running, the CAD cell will detect it; 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
sooting of the combustion chamber and smoke pipe. To deactivate the "LOCKOUT" mode, press and hold
the reset button of the control for 30 seconds.
A green diagnostic LED on the control has four states:
- On = Flame present
- Off = No flame
- 2 seconds On, 2 seconds Off = "Recycle" mode
- 1/2 second On, 1/2 second Off = "Lockout" mode TEMPORARY SHUT-OFF
By pressing and holding the reset button, the burner will shut-off until the reset button is released. Then,
the control will start over at the beginning of the normal cycle.

BURNER INSTRUCTION MANUAL.
