8. Install flange and burner
Important:
Secure the sliding flange so that the
clamping screw 3 is positioned at the top!
When installing the sliding flange, only tighten screws
1 and 2 otherwise it will not be possible to secure the
burner tube with screw 3. Slide in the burner, adjust to
furnace depth and tighten the screws in the following
sequence: 3, 4, 5, raising the housing in the process.
9. Checking electrode setting
• Move the burner into the service position as
described on Page 6.
• Check the setting of the ignition and ionisation elec-
trodes (see Page 11).
10. Installing the gas train
• Remove plastic protective plug.
• Mount the connections and apply the seals
included.
• Observe the installation position.
• Check connecting point of gas ramp with non-corro-
sive foaming agent for leaks and vent the gas pipe.
• When venting, use a hose to discharge the gas
safely to the atmosphere.
For proportional pressure control
GG 20/25(-Z)-M-L-LN with KEV:
Fit the furnace pressure meter tube to the boiler door
with the gradient towards the boiler (if required).
Lay the pressure impulse to the KEV to the corre-
sponding connections p
L
and p
F
.
Use the blue PU hoses supplied.
• Lay the pressure impulse so that no condensate
can flow into the gas ramp.
• Connect hose to furnace pressure meter tube with
connection p
F
(if required).
• Connect hose to connection p
L
with measuring nip-
ple for
air pressure on burner base plate.
If this connection is not made, the magnetic valves
will not open.
