Start-up
Single-stage gas burner with compact units:
Gas supply pressure measuring point
A
(P
inlet
)
Gas nozzle pressure measuring point
B
(P
outlet
)
p
S
= starting gas pressure
p
G
= main gas pressure
p
w
= switching point of gas pressure switch
p
L
= screw cap starting gas pressure
ST
= screw cap
D
= gas volume adjustment (only on KE
10)
Presetting (only on KE 15):
Locate relevant line of adjustment table according to boil-
er output and adopt setting values.
• Adjust dimension
"A"
according to specifications of
adjustment table.
Gas nozzle pressure
≤
5 mbar:
•
P
G
: adjust main gas pressure on min.
•
P
s
: adjust starting gas pressure according to the spec-
fications of the adjustment tables.
Gas nozzle pressure > 5 mbar:
•
P
G
:adjust main gas pressure according to the specifica-
tions of the adjustment tables.
•
P
s
: starting gas pressure to approx. 40-60% of main
gas pressure , min. 4 mbar.
Precision adjustment KE 10:
•
Measure gas nozzle pressure at measuring point
B
.
•
Increase main gas pressure via gas volume throttle
D
in direction
"+“
(
"-“
decrease). Adjusting range
approx. 3 - 14 mbar.
•
Adapt dimension "A“ air volume adjustment (see adjustment tables pp. 10-11).
•
If gas nozzle pressures are less than 3 mbar, turn the gas volume throttle
D
in direction
"-“
until
approx. 3 mbar is reached.
•
Turn adjusting screw
P
G
in direction
"-“
and reduce the nozzle pressure.
•
Only if gas nozzle pressures are greater than 14 mbar:
Turn gas volume throttle
D
in direction
"+“
up to the stop. For further procedure see precision adjust-
ment KE 15.
Installation of compact unit
Installation position, vertical line:
as desired
Installation position, horizontal line:
tilted up to max. 90° to left or right, not over head
Minimum distance to walling:
20 mm
