4.9.4 Checking the gas pre-installation
Ɣ Compare the available gas type with the set position of the
setting screw on the safety gas control block (fig. 4-32,
item 1).
– 1 = Natural gas
– 2 = Liquid gas
Î The gas type must match.
Î If the burner is not set to the available gas type, convert it
to the new gas type (fig. 4-33) and mark it
(see chapter 7.3 "Burner setting").
Ɣ Turn the screw in the measuring connection inlet gas
pressure (fig. 4-32, item 3.3) half a turn in an anti-clockwise
direction.
Ɣ Vent the gas line in
a professional manner.
Ɣ Insert the measuring hose of the pressure meter onto the
measuring connection inlet gas pressure (fig. 4-32, item 3.3).
Ɣ Check the inlet gas pressure.
Î If the gas inlet pressure lies below the permissible range
(tab. 12-5), inform the responsible gas supply company.
For liquid gas: Check the pressure regulator or set the
burner to the permissible gas inlet pressure
(see section 7). This adaptation must be appropriately
labelled with a suitable burner settings sticker and an
entry on the
settings type plate (fig. 3-2 / fig. 3-5, item 33).
A conversion of the gas type must also be adjusted in
the control. Observe the enclosed Control System
