Set-up and installation
4.8.3 Removing/attaching the heat cell panelling
●
Unscrew the locking screws from the lid (fig. 4-43, item 1) and
the front panelling of the heat cell (fig. 4-43, item 2).
●
Remove the lid and front panelling of the heat cell.
Assembly is carried out in reverse order.
Comply with the stipulated tightening torque (see
chap. 12.3).
4.8.4 Checking the gas presetting
●
Compare the available gas type with the position set for the
setting screw
on the safety gas control block (fig. 4-44,
item 3.1).
– 1 = Natural gas
– 2 = Liquid gas
The gas type must match.
If the burner is not set to the available gas type, change it
over to the new gas type (fig. 4-45) and mark it (see
chap. 7.3).
Check the inlet gas pressure
●
Turn the
screw
in the inlet gas pressure
measuring
connection
(fig. 4-44, item 3.3)
half a turn
anticlockwise
.
●
Vent
the
gas line
in a professional manner.
●
Connect the pressure gauge measuring hose to the inlet gas
pressure measuring connection (fig. 4-44, item 3.3).
●
Check the inlet gas pressure.
If the gas inlet pressure lies outside the permitted range
tab. 12-6, inform the responsible gas supply company.
For liquid gas: Check the pressure reducer and set the
burner to the permissible gas inlet pressure (see chap. 7).
