HUPF Series
HUPF Series
GAS PRESSURE REGULATOR WITH
INCORPORATED FILTER
INSTRUCTION SHEET
DESCRIPTION
Spring-loaded regulator with inlet pressure compensation
and zero shut-off.
The outlet pressure is kept constant with changing gas flow
as a function of the spring setting. The zero shut-off prevents the
outlet pressure from increasing when there is no gas flow through
the regulator.
APPLICATION
To regulate gas and air inlet pressure for gas burners, including
mixed and combined systems and in industrial distribution systems.
Applicable types of fuel:
manufactured gases (town gas)
• natural gases (group H - methane)
• liquefied petroleum gas (LPG)
• non-aggressive gases
• air
The gas pressure regulators comply with the requirements of
EN88-1, class B, group 2.
These gas pressure regulators are available in two versions;
with or without incorporated filter, see product range page 2.

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.
• 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.
Main regulator connection flanged
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.

ADJUSTMENTS
Caution
• Adjustments must be made by qualified
personnel only!
Outlet pressure adjustment
(Tolerance: better than 15% of outlet pressure setting)
1. Remove the upper cap (1).
2. To obtain the required outlet pressure value, turn the set
screw (4). Turn this set screw clockwise to increase the
outlet pressure, counter-clockwise to decrease it.
3. Clearly mark the adjusted value of the outlet pressure.
4. Replace the upper-cap (1) and seal it with lead if necessary.
Replacing spring
1. Remove the upper-cap (1) of the pressure regulator.
2. On fully unscrew the ring nut (4)
3. Remove old and replace new spring.
4. Screw the ring-nut (4) back in.
5. Adjust the required outlet pressure by proceeding with
step 1 to 4 of „Outlet pressure adjustment“ section on
this page.
Final checkout of the installation
Set the appliance in operation after any adjustment and
observe several complete cycles to ensure that all burner
components function correctly.
MAINTENANCE
The regulators are completely maintenance-free. In the event
of a breakdown, a general overhaul and factory testing is
recommended.
Filter maintenance (HUPF)
1. Remove the screws at the bottom of the gas regulator and
remove the cover.
2. Remove the filter cartridge and/or membrane and clean the filter housing
thoroughly.
3. Replace the old filter element and/or membrane with the new one.
4. Reassemble the cover, ensuring that the guides inside the
cover is aligned with the filter cartridge.
5. Tighten the screws, and check for gas leak by performing
a tightness test.
