The connection of a room thermo- he connection of a room thermo-
stat or a day/night temperature
control takes place for these types
at the respective terminal strips in
the control box.
Connection must be carried out as

■ The burner must be set to the
full heat load of the appliance.
■ The combustion chamber must
not be overloaded
(increased condensate forma-
tion).
■ The exhaust fume temperature
should be about 180 Kelvin
above room temperature.
There is otherwise the risk
of increased condensate
formation
!
■ The separate operating instruc-
tions of the factory supplied
burner must be observed.
■ When using forced-air burners
of other manufacturers, their
suitability for the appliance
must be verified (hot air heater
type).
Gas connection
A sufficient gas volume and gas
pressure corresponding to the
power of the heating appliance
must constantly be available whilst
the appliance is in use.
■ Installation of the gas connec-
tion must only be carried out by
authorised specialists.
■ To be observed are DIN 4756
or the DVGW worksheet G 600
for gas-fired hot air heaters and
TRF for liquid gas.
■ Gas pressure regulating devices
and shut-off valves must be
provided on site.
■ The cable cross-section must
be dimensioned, taking into
account the installed load of the
appliance, total line resistance
and gas pressure.

Prior to initial use, the gas
supply pipe must be cleaned
thoroughly and checked for
leaks!
Fuel oil connection
A sufficient and correct fuel supply
must be ensured.
■ The suction pipe must be provi-
ded with a foot valve in the fuel
oil tank.
■ Free flowing fuel oil must be
available in sufficient quantity
also at low outside tempera-
tures.
Paraffin formation can occur
already from about 5°C depen-
ding on the fuel oil quality.
Appropriate measures must be
taken to prevent this occurring!
Burner installation
The factory supplied forced air-
burner is mounted on the front
of the appliance with a clamping
flange.
The following must be observed:
■ Only type-tested hot air heat- type-tested hot air heat-
ers with forced-air oil burners
complying with DIN EN 267 or
forced-air gas burners (comp-
lying with DIN EN 676) may be
used.
■ Power limitation for single-
stage burner operation (up to
70 kW) is not required for hot
air heaters.
AttENtION
Installation, adjustment and
maintenance of the gas supply
must only be carried out by
specialists authorised by GVU!
