5.
Hinge the electronics box upwards.
6.
Open the gas stopcock.
7.

.
8.
Measure the gas connection pressure/gas flow pres-
sure against the atmospheric pressure.
Permissible connection pressure
Great
Bri-
tain
Natural gas
H
1.7 to 2.5 kPa
(17.0 to 25.0 mbar)
Liquefied petro-
leum gas
P
2.5 to 4.5 kPa
(25.0 to 45.0 mbar)
Note
The connection pressure is measured at the
gas valve assembly, meaning that the per-
missible minimum value may be 0.1 kPa (1
mbar) lower than the minimum value spe-
cified in the table.
Result 1:
Gas connection pressure/gas flow pressure in the per-
missible range
▶
Temporarily decommission the product. (
▶
Hinge the electronics box downwards.
▶
Remove the manometer.
▶
Tighten the screw on the test nipple.
▶
Open the gas stopcock.
▶
Check the test nipple for gas tightness.
▶
Hinge the electronics box upwards.
▶
Install the front casing. (
▶
Start up the product.
Result 2:
Gas connection pressure/gas flow pressure not in the
permissible range
Caution.
Risk of material damage and oper-
ating faults caused by incorrect gas
connection pressure/gas flow pres-
sure.
If the gas connection pressure/gas flow
pressure lies outside the permissible
range, this can cause operating faults
in and damage to the product.
▶
Do not make any adjustments to the
product.
▶
Do not start up the product.
▶
If you are unable to eliminate the fault, contact the
gas supply company.
▶
Close the gas stopcock.
