INSTALLATION MANUAL
LANDIS gas valve
Version with SPK10: no adjustment necessary.
- Important: Do not remove the cover as oil may leak out.
Version with SKP20: (with built in pressure stabiliser).
- To increase or decrease gas pressure, and therefore gas flow, remove the cap
and use a screwdriver to adjust the regulator screw VR. Turn clockwise to increase
the flow, anti-clockwise to reduce it.
- Connect up the gas tubing to the gas pressure nipple (TP in Fig.14).
- Leave the breather free (SA in Fig.14).
- Should the spring that is fitted not permit satisfactory regulation, ask one of our
service centres for a suitable replacement.

Leak Detection KROM SCHRODER TC218
This device checks the closure of the gas valves by acting directly on them
according to a sequence controlled by an electronic programme. The device
includes light signals (LEDs) to indicate the phase of the cycle of operation and
which solenoid valve is leaking. If a momentary loss of voltage occurs during the
test the system automatically starts up again. If that happens during a test failure
both LEDs light up.
Legend of Light Signals
A - Test in progress
B - Regular operation
C - Loss of upstream solenoid valve (EV1)
D - Loss of downstream solenoid valve (EV2)
