4 Technical Data
Where no threshold values are specified technical data
are understood to include standard tolerances for heater
units of ±10% at ambient temperature of +20° C and at
nominal voltage.
4.1 Electrical Components
Control unit, motor, dosing pump, glow plug resistor,
part load resistor, timer and switch with indicator light are
12 V or 24 V components.
Temperature limiter, flame sensor and glow plug are
identical in 12 V and 24 V heaters.
Glow plug default voltage is 4.2 V +0.1/–0.15 at nominal
voltage at control unit input (A1).
