INTRODUCTION

1.1 Basic Information
The instructions in this manual apply to Model
LCSC-3E 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 installed at an operation
ambient temperature between -15°C and 45°C.
When installed as a type C12/C32 and where
LCSC-3E--EN 2/40
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.
Heaters are approved for:
Type C12 horizontal vent for balanced-flue
heaters;
Type C32 vertical vent for balanced-flue
heaters;
Type B 22 vertical vent;
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.
1.2 Warranty: Warranty is void if:
a) LCSC-3E heaters are installed in atmospheres containing flammable vapors or atmospheres
containing chlorinated or halogenated hydrocarbons or atmospheres containing any silicone,
aluminum oxide, etc., that adheres to spark ignition flame sensing probes.
b) The installation is not in accordance with these instructions.

(1) Gas appliance Classifications for approved venting methods based on CEN report CR 1749:2001.
(2) There is a difference between the gas connection diameter and the diameter of the supply line. Always use the most
adequate diameter of the supply line to minimize the pressure drop through the gas pipes – if necessary, reduce the
diameter of the supply line at the inlet of the unit.
