INSTALLATION AND FINAL CHECKOUT
Warning
:
Take care that installer is a trained
experienced service man.

Disconnect power supply to
prevent electrical shock and/or
equipment damage.
Mounting position
The gas valve can be mounted plus or
minus 90 degrees from the vertical.
Mounting location
The distance between the gas valve
and the wall/ground, must be at least
30 cm.
Main gas connection threaded
valves
:
Take care that dirt cannot enter the
gas valve during handling.
:
Ensure the gas flows in the same
direction as the arrow on the housing
of the gas valve.
:
Use a sound taper fitting with thread
according to ISO 7--1(BS 21, DIN
2999) or a piece of new, properly
reamed pipe, free from swarf.
:
Do not thread or tighten the pipe or
pipe fitting too far. Otherwise valve
distortion and malfunction could
result.
:
Apply a moderate amount of good
quality thread compound to the pipe
or fitting only, leaving the two end
EN2R--9012 9412R0--NE
threads bare. PTFE tape may be
used as an alternative.
:
In order to tighten the pipe in the
valve, do not use the actuator as a
lever but use a suitable wrench
operating on the wrench bosses.
Main gas connection flanged valves
:
Take care that dirt cannot enter the
gas valve during handling.
:
Ensure the gas flows in the same
direction as the arrow on the housing
of the gas valve.
:
Ensure that inlet and outlet flanges
are in line and separated from each
other enough to allow the valve to be
mounted between them without
damaging the gasket.
:
Place gasket. If necessary grease it
slightly to keep it in place.
:
Mount gas valve between flanges
using the bolts for each flange.
Warning
Tightness test after installation

A gasket leak can usually be
stopped by tightening the mounting
screws. Otherwise, replace the gas
valve.
