Installation
Single pipe system
For pure single-pipe operation the bypass stopper
must be unscrewed out of the return line opening and
the return line opening must be sealed with a gasket
and metal stopper.
For conversion to single pipe system, we recommend
to use a fuel oil filter with return feed. For this, the
pump remains in two-pipe operation. Install flow and
return burner pipes at the filter. Open the oil tap at the
filter. Start the installation.
Oil pump
On the
version -AE
(startup relief) or
-Z
(two-stage)
the oil burner starts up with a low pump pressure and
switches to the higher pump pressure, i.e. full output,
via the solenoid valve in the pump.
-AE
Differential pressure max. 3 bar. Ex-works setting
10 and 13 bar.
-Z
Ex-works setting 10 and 20 bar
The pump pressure can be set for the relevant output
(see Table of settings Pages 13-14).
To do so:
•Remove the sealing plug.
•Screw in the pressure gauge and adjust the pump
pressure by means of the control valve in accor
dance with the table of settings.
