Installation instructions
GAS LINE INSTALLATION
IMPORTANT:
Cement and chalk can damage the piping and can, in turn, lead to gas leaks.
IMPORTANT:
Screw the thermocouple connection (and thermocouple interrupter)
manually into the gas regulator block. Afterwards, carefully fasten a
half turn with a spanner.
Disassembly and assembly of pipes and cables:
If necessary for mounting, all pipe compression fi ttings and cable connectors can be
temporarily disassembled. After mounting, carefully reassemble all pipes and cables.
Check afterwards all compression fi ttings for leaks and that all electric connections are
properly connected.
Note:
Check that the fl
exible burner pipes are correctly connected! The gas connection
of the gas valve “rear burner” must be connected to the “rear burner”!
See fi gure 19 and Chapter; DIAGRAM ELECTRICITY AND GAS.
Switching over the fl exible burner pipes during assembly can lead to an explosive
ignition. Prevent this at all costs!
The appliance must not be subjected to any test pressures exceeding ½ psi
(= 3.45 kPa = 34.5 mbar). Isolate or disconnect this and any other gas appliance control
from the gas line when pressure testing.
After connection of the gas supply, check that all connections are completely gas tight
using soapy water (mixture of 50/50 water and soap solution) or a leak tester.
WALL-MOUNTED-APPLIANCE - Gas connection under the appliance
All installation conditions are entirely identical to those of the BUILD-IN model.
Except that there is no built-in operating unit, because the gas regulator block and
receiver are located underneath the appliance.
