 The Ambi-Rad Centurion range is a
new generation of gas-fired air heating products.
Designed to enhance energy efficiency, provide simple low
cost installation and to facilitate ease of maintenance.
The units offer considerable benefits at the most
competitive cost.

The patented, new low resistance heat exchanger allows
more than 20% additional airflow without any increase in
fan speed or electrical consumption.
CENTURION UFE
 The Centurion UFE provides additional Fuel
Economy by incorporating an integral powered flue and
automatic spark ignition as standard features. The power
vented flue eliminates the unnecessary loss of heated air
that is associated with open flues, thus providing
significant energy savings.
This combination of energy
saving features, and reduced installation costs,
generally allows the additional costs of the higher
specification units to be recovered within the initial
year of operation.
Furthermore, roof
penetrations can be avoided as the rear flue outlet on
the Centurion UFE allows the use of a simple through the
wall terminal.

† Maximum
inlet pressure 30 mbar. Minimum inlet pressure 17.5 mbar.
* Use lower mounting height unless a downturn
nozzle is fitted. Throw depends on height of building,
mounting height of heater, room temperature and louvre
setting.
• Reduce flue length by 3m for each
90° bend.
