What to do if you smell gas
• Prevent open flames or sparking, e.g. do not turn lights on or off, do
not use any electrical appliances, do not use mobile phones. Open
windows and doors. Close the gas ball valve. Warn residents; do not
use doorbells. Vacate the building. Notify the company/installer or gas
supplier once the building has been vacated.
• Turn off the equipment and take the boiler out of operation. Open
windows and doors. Notify the company/installer.
• Check that the burner is approved for the intended grade of gas and
connection pressure.
• No safety systems on the burner may be disconnected.
• General advice on how to eliminate a fire
• One or more boilers for solid or liquid fuel whose total rated output
exceeds 60 kW should be installed in a separate boiler room. An
airlock should be the only way a separate boiler room is connected
to evacuation routes from residential buildings in activity class 3, and
offices in activity class 1 that do not constitute an integrated part of an
industrial activity or similar activity. (Swedish building regulations BFS
2011:26).
• The term “separate boiler room” refers to boiler rooms which are
specially designed to provide protection against the starting and
spreading of fire and the production and spreading of combustion gas.
(Swedish building regulations BFS 2011:26).
• Separate boiler rooms and fuel stores immediately next to a separate
boiler room should be designed as individual fire compartments.
(Swedish building regulations BFS 2011:26).

2.1.2 Functional discription of gas
flow
1. When the valves V1 and V2 are closed, chamber A
is under inlet pressure.
2. A hole D in the filter housing connects min.
pressure switch with chamber A. If the inlet
pressure applied to the pressure switch exceeds
the incoming reference value, it switches through
to the automatic burner control.
3. After release by the automatic burner control,
valves V1 and V2 open. The gas flows through
chambers A, B and C of the GasMultiBloc.
2.1.3 Operating method of valve-
regulator combination on valve
V1
A regulator, compensating for residual pressure is
integrated in valve V1 (pressure regulating part). Armature
7 is not connected to valve plate unit 3. When it opens,
armature 7 pretensions compression spring (V1) 5 and
releases the valve plate unit. When the valve closes, the
armature acts directly on the valve plate unit. The output
pressure upstream of valve 2 is defined by pretensioning
regulating spring 8 (tension spring) via setting screw 16.
The output pressure acts via opening E on the working
diaphragm of regulator part 1. In regulated state, setting
spring inlet pressure and pressure of working diaphragm
are in force equilibrium.
2.1.4 Operating method of valve V2
Armature 13 of valve V2 is connected to valve plate unit
11. When it opens, armature 13 pretensions closing
spring 12. The maximum valve opening can be set
by limiting the armature stroke by means of the main
volume restrictor 17. Min. opening (residual stroke) of
valve (0.5 to 1.0 mm) Main volume restrictor 17 is set by
rotating the adjusting plate or the hydraulic brake 19. The
fast and/or slow opening characteristic is influensed by
setting the fast stroke 18 at the hydraulic brake 19 under
the cover.
2.1.5 Closing function
When the supply voltage to the solenoid coils of valves
V1 and V2 is interrupted, they are closed within < 1 s by
the compression springs.
2.1.6 Closing stroke limitation
(option)
A partial volume setting is possible by means of a closing
stroke limiter. Valve V2 becomes a regulating actuator
without zero shutoff. Partial volume and main volume are
adjustable.

2.2.2 Functional description of gas
flow
1. When the valves V1 and V2 are closed, chamber A
is under inlet pressure.
2. A hole D in the filter housing connects min.
pressure switch with chamber A. If the inlet
pressure applied to the pressure switch exceeds
the incoming reference value, it switches through
to the automatic burner control. After release by
the automatic burner control, valves V1 and V3
open.
3. The gas flow through chambers A, B and via
bypass valve V3 in C of the GasMulti-Bloc is
released. The ignition gas volume is adjusted by
using the bypass restrictor. The pressure regulator
controls the pressure upstream of valves V2 and
V3.
4. When valve V2 is released, the gas flows directly
into chamber C, the bypass valve V3 remains
open. On request, the second stage of valve V2
opens.
2.2.3 Operating method of valve-
regulator combination on valve V1
A regulator, compensating for residual pressure is
integrated in valve V1 (pressure regulating part).
Armature V1 is not connected to the valve plate
unit. When it opens, the armature pretensions the
compression spring and releases the valve plate unit.
When the valve closes, the armature acts directly on the
valve plate unit. The output pressure upstream of valves
V2 and V3 is defined by pretensioning the regulating
spring 7 (tension spring) via setting screw 18. The output
pressure acts via opening E on the working diaphragm
of the regulator. In regulated state, setting spring inlet
pressure and pressure of working diaphragm are in force
equilibrium. The compensating diaphragm 23 ensures
the fast closing function of valve V1 and a high regulating
quality.
2.2.4 Operating method of bypass
valve V3
The bypass valve V3 opens at the same time as valve
V1. Ignition gas flow is set by using bypass restrictor 28.
2.2.5 Operating method of valve V2
The armature 14 of valve V2 is connected to the
valve plate unit 12. When it opens, the armature 14
pretensions the compression spring 13. The maximum
valve opening can be set by limiting the armature stroke
by means of the main volume restrictor 20.
2.2.6 Min. opening (residual stroke)
of Valve (0.5 to 1.0 mm)
The main volume restrictor 20 is set by rotating the
adjusting plate or the hydraulic brake. When the second
stage of valve 2 opens, compression spring 13 is
continuously pretensioned. The maximum valve opening
of the second stage can be set by limiting the armature
stroke by means of the main volume restrictor. The main
volume restrictor is set by rotating the adjusting plate
or the hydraulic brake. The fast and/or slowl opening
characteristic is influenced by setting the fast stroke 21
at the hydraulic brake under the cover.
2.2.7 Closing function
When the supply voltage to the main valve solenoid coils
is interrupted, the valves V1, V3 and V2 are closed within
< 1 s by the compression springs.

!For maintenance of the brake plate, nozzles, electrodes etc, when using a long
design of the burner tube, you have to remove the nozzle assembly from the
connecting pipe and move the assembly backwards in the fan housing (from the
boiler).
Fit the burner to the boiler by means of 4 bolts M12. For flange and bolt
dimensions see technical data.
If for some reason you want to separate the burner from the gas flange with
burner head and valve package you can do so.
Do like this:
• Remove the cover of the fan housing.
• Loosen the nut D of the gas assembly package.
• Loosen the electric cables to the valve package.
• Loosen the screws B on both sides.
• Loosen the stop bolt C on the pull rods.
• Loosen the ignition cable and the ionisation cable from the gas
assembly.
• Pull out the burner on the pull rods and put it in a suitable place.
When the burner head and the gas flange have been fitted to the boiler it is
easy to lift up the burner to where it belongs.
4.1 Inspection of gas assembly
If the gas assembly needs to be inspected the pull rods are very useful.
Do like this:
• Remove the cover of the fan housing.
• Loosen the nut D of the gas assembly package.
• Loosen ignition cable and ionisation cable of gas assembly.
• Loosen the screw A on both sides.
• Pull out the burner on the pull rods.
• Loosen the screws B on the gas flange.
• Withdraw the gas assembly.
Ensure that the O-ring between the gas assembly and the gas flange will be
in the correct position when the gas assembly is fitted again

4.2 Adjustment of the position of the
shrouded disc in the blast tube
Sometimes it is necessary to adjust the position of the shrouded disc in the
blast tube. This can be done with the screw E (can be adjusted when the
burner is in operation). If you turn the screw to the left the shrouded disc will
move forward (+), to the right it will move backward.
