The 'ST' series heaters are room-sealed, fan assisted, balanced flue units incorporating a separated combustion system. Separated combustion technology provides mechanically induced outside air for combustion, preventing dirt, lint, dust or other contaminates from entering the burners or combustion process. The room sealed units provide significant improvements in seasonal efficiency and reduced running costs compared to conventional open flued heaters.

COMPREHENSIVE RANGE
The units are available in eleven output capacities from 17kW to 93kW

CHOICE OF FUELS
Standard units are suitable for operation on natural gas; units for propane are available as an option, 

VERSATILE INSTALLATIONS
Heaters are designed for either suspended or base mounted installation. Units may be either freeblowing or fully-ducted. A range of outlet nozzles is available to give greater flexibility of air distribution. For ease of servicing, the burners are mounted in a slide out drawer, accessed from the left hand side of the heater (viewed from the front). Opposite hand units with right hand side access are available as an option.

OPTIONAL BURNER CONTROLS
Two-stage, high/low burner regulation provides closer temperature control. Since the heater runs for longer periods on low setting, the air circulation is improved and stratification is significantly reduced. The two-stage control system is particularly beneficial on ducted systems. Modulating burner regulation provides proportional control between high- and low-fire, for even closer temperature control. The modulating control system is ideal for make-up air applications.

ECONOMY
The Thermocore Heat Exchanger provides optimum efficiency and economy. Room-sealed ST units provide additional fuel economy, with fully automatic ignition and integral-powered flue being fitted as standard. The sealed power flue system eliminates the loss of heated room air associated with conventional flue systems, thus providing significant energy savings. The design also utilises waste heat from flue gasses to preheat incoming combustions air, maximising combustion efficiency.
