4. Technical Data
4.1 General Information
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 (+ 68 °F) and at nominal voltage.
Electrical components:
Control unit, fan and circulation pump motors, solenoid valve, igniter box, heater cartridge, nozzle pre-heater and
timer are 24V components. Temperature limiter, flame sensor, temperature sensor and switches are voltage
independent components.
