INSTRUCTIONS FOR INSTALLATION

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.
