DESCRIPTION OF TBG 45 / 60 OPERATION
When the main switch and the I/O switch (22) on the
electrical panel are closed, if the thermostats are closed,
voltage will reach the command and control device,
which starts up the burner (led 19 comes on).
This turns on the fan motor for preventilation of the
combustion chamber.
The ignition transformer then comes on, and 2 seconds
later the gas valves open.
The main valve, which has two stages, has a device for
adjusting gas delivery for the first and second flame.
The safety valve is an ON/OFF valve.
Combustion air may be adjusted manually using the air
lock (see section entitled “Diagram for adjustment of air
in single-stage burner TBG 45-60”).
As the burner is ON/OFF, the position of the air lock
must be regulated for operation at maximum capacity.
The presence of the flame, detected by the control
device, permits continuation and completion of ignition,
turning off the ignition transformer.
The second flame then comes on (the second stage in
the main valve opens).
If there is no flame, the appliance shuts down in “safety
lock-out” mode (led 20 comes on) within 3 seconds of
the opening of the first flame on the main valve.
In “safety lock-out” mode the valves are closed again
immediately.
To release the appliance from safety lock-out mode,
press button (21) on the electrical panel.
DESCRIPTION OF TBG 45P
- 60P OPERATION
When the main switch and the I/O switch (22) on the electrical
panel are closed, if the thermostats are closed, voltage will reach
the command and control device, which starts up the burner (led
19 comes on).
This turns on the fan motor for preventilation of the combustion
chamber. At the same time, the servomotor commanding the air
lock opens in the position corresponding to the second flame, so
preventilation takes place with the air lock in the second flame
position.
At the end of the preventilation phase, the air lock is returned to
the first flame position, then the ignition transformer comes on
and, 2 seconds later, the gas valves open.
The main valve, which has two stages, has a device for adjusting
gas delivery for the first and second flame.
The safety valve is an ON/OFF valve.
The air lock is operated by an electric servomotor(see
0002934711). Keep in mind that when the burner is locked out
because the thermostat is tripped, the servomotor returns the air
lock to the closed position.
The presence of the flame, detected by the control device, per-
mits continuation and completion of ignition, turning off the ignition
transformer. The second flame then comes on (combustion air is
increased and the second stage of the main valve opens).
If there is no flame, the appliance shuts down in “safety lock-out”
mode (led 20 comes on) within 3 seconds of the opening of the
first flame on the main valve.
In “safety lock-out” mode the valves are closed again immediately.
To release the appliance from safety lock-out mode, press button
(21) on the electrical panel..
