EATER
The auto heater is based on an
extremely efficient heat exchanger
consisting of a pair of internally and
externally finned aluminium die-
castings.
The gas burner is at the bottom of
the vertical passage that permits
complete combustion of the gas
before meeting with the heat
exchanger surfaces.The combustion
products travel along the top
horizontal section then downwards
to further galleries while transferring
their heat to the motorhome.
The flue outlet is at the bottom of
the heat exchanger thus ensuring
that the majority of the heat
extracted from the combustion path
is completely sealed from the living
space. All the air for combustion is
drawn from beneath the
motorhome through the air intake
and the products of combustion are
discharged through a flue pipe to a
roof-mounted terminal.
The heater is controlled by a knob
mounted on the top of the heater
case which operates a thermostatic
gas valve. Ignition is by an electric
re-ignition system powered by two
AA size batteries and operated by a
micro-switch mounted on the
thermostatic gas control.
a Control knob (Thermostat).
b Integrated control switch for the
Trumavent fan TEB.
c Pressure igniter (S3003P only).
d Automatic ignition device with
battery compartment.
e Remote ignition display (optional).
f Window to check flame.
g Thermostat sensor.
h Name plate (remove cover).
Operating Instructions
