This appliance is fitted with a TTB
The TTB is a flue spillage sensor that reacts to flue gasses
flowing past the baffle in the heater back into the living
room.
In the event of a flue spillage, the thermocouple is
interrupted by the TTB, shutting off the gas supply to the
burners.
This protective device will prevent flue gasses from flowing
into the home for any length of time.The device will reset
itself after a few minutes and the heater can then be
reignited.
Possible causes of the TTB being activated
include:
• There is little or no supply of fresh air into the home (all
draughts have been excluded and ventilation openings
sealed off).
• The outlet into the flue duct is partially or completely
blocked.
• The chimney mouth was not constructed correctly, can
cause "fall winds" in the chimney duct being a possible
result.
Measures to prevent TTB activation
The heater can be reignited once the TTB has cooled
down.
If the safety device is activated again, open a window or
some other means of ventilation.
If this resolves the problem, it means that the home is
hermetically sealed and the heater is unable to discharge
all the combustion fumes through the chimney. Some
means of ventilation must be kept open or constructed. If
the safety device is still activated after that, examine the
other possible causes listed above and resolve accordingly.
The safety device may never be disconnected.
The TTB
The TTB safety device has several special components that
should also be incorporated in a replacement TTB.You are
strongly advised not to fit a "standard" thermocouple.
INSTRUCTIONS FOR USE
Type EUROSIT
The EUROSIT gas control block has the following controls:
*
rotary switch with the following settings (1):
• off ( )
• ignition and pilot light ( )
• thermostat
*
push button (2) to operate the piezo ( )
*
manual control (3) for the following settings:
• on full
Adjustable between the maximum and minimum
setting of the manually operated gas tap.
• off
Operating
To ignite the pilot light turn the switch (1) to ( ) and
press fully.Turn button (2) a few times as necessary. Once
the pilot light is ignited, keep pressing the button for
approx. 10 seconds. If you release the button the pilot light
should stay alight, if not, repeat the stages above, pressing
the button for a little longer. If the thermostat has been
set to a temperature higher than the room temperature,
the main burner will ignite when the button is released.
The required temperature can be set using the thermostat
button (1).
NB:
Should the thermostat demand heat it will have priority
over any manually controlled setting.
If the heater is only to be controlled manually, turn the
thermostat to the lowest setting.
If the thermostat is set to ( ), only the pilot light will
burn. Neither the thermostatic tap nor the manually
operated tap will work.
Switching off
To s witch the heater off, turn the switch (1) to . This
will switch both the main burner and the pilot light off.
Switched to the pilot light setting ( ) only the pilot light
will stay alight.
If the heater has been switched off, wait for 5 minutes
before relighting.
