INSTALLATION
IMPORTANT
Take care that installer is a trained experienced
service person.
Turn off gas supply before starting installation.
Disconnect power supply to prevent electrical shock
and/or equipment damage.
Do not remove seals over inlet and outlet until the
device is ready to be installed.
If M5 connection for switchable softlite and/or
pressure feedback is/are not to be used, it is to
recommend to push a dust cap into the hole
(order nr. 45.900.426- -001).
Mounting position
The combination gas control can be mounted 0 to 90_ in any
direction from the upright position, i.e. from the position when
electric operators are on top.
Main gas connection
· Take care that dirt cannot enter the combination gas
control during handling.
· Use a clean taper fitting with thread according to ISO 7--1
or a piece of new, properly reamed pipe, free from swarf.
· Do not tighten the pipe or pipe fitting too far (see table
below). Otherwise valve distortion and malfunction could
result.
Pipe size Max. length of pipe thread

/ " 18.6 mm

· Apply a moderate amount of good quality thread
compound to the pipe or fitting only, leaving the two end
threads bare. PTFE tape may be used as an alternative.
· Ensure that gas flows in the same direction as the arrow
on the bottom of the combination gas control.
Pressure feedback connection
WARNING
To avoid decreasing of performance of pressure
regulator by pinching--off the pressure feedback
tubing, it is to recommend a metal tubing.
Pilot gas connection (VR4601/VR8601 only)
· Square off the end of tubing and remove burrs.
· Slip compression fitting over tubing.
· Insert tubing into housing of combination gas control until it
bottoms, slide fitting into place and turn finger tight.
· Use a wrench to tighten fitting about 2 turns beyond finger
tight for 6 mm tubing and about
for 4 mm tubing to make a pressure tight joint.
Do not use jounting compound.

· Connect other end of tubing to pilot burner according to the
pilot burner manufacturer's instructions.
CAUTION
Do not bend tubing at combination gas control after
compression fitting has been tightened, as this may
result in gas leakage at the connection.
Remember that length of pilot tubing and pilot
burner characteristics have influence on time to
ignite pilot burner.
This can interfere with available ignition timings.
Electrical connection
CAUTION
Switch off power supply before making electrical
connections.
Take care that wiring is in accordance with applicable
codes and local regulations.
To ensure a safe closing of the valve, it is essential
that the voltage is reduced to 0 Volt.
Ensure that cut- -off function of limit control
de- -energizes both valves.
Use lead wire which can withstand 105 _C ambient.
The electric on/off operator is provided with:
6.3 mm quick connect terminals suitable for 6.3 mm
receptacles. (e.g. "Series 250" AMP fasteners)
The electric servo on/off operator is provided with:
6.3 mm quick connect terminals suitable for 6.3 mm
receptacles. (e.g. "Series 250" AMP fasteners)
or with:
quick connect terminals suitable for a female connector
according DIN 43650.
Wiring combination gas controls in intermittent pilot (IP) systems
The appliance manufacturer's instructions should always be
followed when provided. If not available see fig. 2. page 26
for typical systems using Honeywell S458 ignition control.
Wiring combination gas controls in direct spark ignition (DSI) systems
The appliance manufacturer's instructions should always be
followed when provided. If not available see fig. 3.page 26 for
typical systems using Honeywell S4560 automatic ignition
control.
