5.1.1 Installing the gas valve train
Only in conjunction with W-MF and gas connection pressure > 150mbar
If the gas connection pressure is >150mbar, a pressure regulator has to be fitted
upstream of the W-MF.
Install the gas valve train, see additional sheet (Print No. 835109xx).
Installing the valve train from the right
Remove protective foil from gas connection flange.
Mount gas valve train free from stresses. Do not compensate for installation er-
rors by over-tightening the flange screws.
Ensure correct alignment of flange seals.
Tighten screws evenly diagonally across.
Installing the gas valve train from the left
To fit the gas valve train to the burner from the left, the burner has to be installed
rotated by 180°. To do this, additional conversion measures are required.
Move the gas pressure switch prior to installing the multifunction assembly:
Remove closing plug 1 and gas pressure switch 3.
Mount gas pressure switch 3 and O ring 2 on the opposite side.
Mount closing plug 1 on the opposite side.
Continue installation in the same way as for "Mount gas valve train from the
right".
