Honeywell HUPF Series Bedienungsanleitung

Gas pressure regulator with incorporated filter

EN1C-0003NL05 R1205

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.
