2.WARNING: Failure to comply could result in severe
personal injury or death and/or property damage.
3.CAUTION: Failure to comply could result in minor
personal injury and/or property damage.

The electrical isolator should only be used in an emergency
and should not be used for closing down the main burner,
as it switches off the fan prematurely and may damage the
heat exchanger, invalidating the warranty.
1.0 INTRODUCTION
1.1 Basic Information
The instructions in this manual apply to Model SCA
gas-fired/fan-assisted warm air heaters. These models have an
axial fan for air delivery. These heaters are designed for overhead
suspension and are suitable for indoor installation only. When
installed as a type C12/C32 and where the height above floor level
is greater than 1,8 meters measured to the underside of the
appliance they may be used as a garage air heater. This appliance
must be installed in accordance with the rules in force. Before
installation, check that the local distribution conditions, nature of
gas and pressure and adjustment of the appliance are compatible.
A permanent electricity supply of 230 volts, 50 Hz, single phase is
required.
Model SCA heaters are approved for:
Type C
12
- horizontal vent for balanced-flue heaters;
Type C
32
- vertical vent for balanced-flue heaters;
Type B
22
- vertical vent;
Category II
2H3 +
for GB and IE
When the external control calls for heat, an electronic control
begins the ignition sequence to provide for a safe start. About 30
seconds after the call for heat, the fan will begin circulating warm
air. The electronic control will supervise the flame during the
entire heating cycle to ensure safe operation.
When the required
room temperature is reached, the main burner will shut down
leaving the fan running to cool down the heat exchanger.
After approximately 45 seconds, the fan delay relay will turn off
the fan.
