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.
No additional sealant is required if the thread is coated in blue.
