WEBASTO DBW SERIES HEATERS TECHNICAL DATA
Technical Data
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
voltage sensitive components. Temperature
limiter, overheat fuse, control thermostat,
flame sensor and switches are voltage
independent components.
