INTRODUCTION
1.1 Basic Information
The instructions in this manual apply to Model VRC ‐ 3 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 the height above floor level is greater than 1,8 metres
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 C
12
‐ horizontal vent for balanced ‐ flue heaters;
Type C
32
‐ vertical vent for balanced ‐ flue heaters;
Type B
22
‐ vertical vent;
Category II

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.

a) VRC-3 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.

(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.
