INSTALLATION
Important
1.
Read these instructions carefully. Failure to
follow the instructions could damage the
product or cause a hazardous condition.
2.
The installation has to be carried out by
qualified personnel only.
3.
Carry out a thorough checkout when
installation is completed.
Warning
Turn off gas supply before installation.
•
Do not remove the seal over regulator
•
inlet and outlet, until ready to connect
piping.
Do not remove the perforated diaphragm
•
breather cap (3) and do not obstruct the
hole.
The regulator must be installed so that
•
the arrow on the regulator points in the
direction of the gas flow.
Mounting position
To ensure perfect regulator operation, regulator
should be assembled horizontally. They can
however be installed in different positions up to an
angle of 90°.
Mounting location
Contact between the regulator and walls or a floor is
not permitted. Maintain a distance of at least 50
mm.
Note:
In case of the HUPF Series, the distance
between the bottom and the ground must
be at least 400 mm, to facilitate filter
cleaning and inspection.
Main gas connection threaded regulators
Take care that dirt cannot enter the gas regulator
•
during handling.
Gas pressure regulator with incorporated filter
Ensure the gas flow in the same direction as the
•
arrow on the housing of the gas regulator.
Use a sound taper fitting with thread according to
•
ISO 7-1 (BS21, 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 regulator distortion and malfunction
could result.
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.
In order to tighten the pipe in the regulator, do not
•
use the sleeve of the upper cover as a lever but
use a suitable wrench operating on the wrench
bosses.

regulators
Take care that dirt cannot enter the gas regulator
•
during handling.
Ensure the gas flow in the same direction as the
•
arrow on the housing of the gas regulator.
Ensure that inlet and outlet flanges are in line and
•
separated from each other enough to allow the
regulator to be mounted between them without
damaging the gasket.
Place gasket. if necessary grease it slightly to
•
keep it in place.
Mount gas regulator between flanges using the
•
bolts for each flange.
Warning
Tightness test after installation
Spray all pipe connections and gaskets
•
with a good quality gas leak detection
spray.
Start the appliance and check for
•
bubbles. If a leak is found in a pipe
connection, remake the joint. A gasket leak
can usually be stopped by tightening the
mounting screws. Otherwise replace the
gas pressure regulator.
