(optional)
• Fill in space 1 with recommended
heat-resistant material or material
supplied by the boiler manufacturer.
Chamber pressure take- off pF should
never be choked.
Combustion head
• Position combustion head, so that gas
train is horizontally connected on the
right.
• The other assembly positions are not
allowed.
• Fix and secure combustion head with
its gasket on boiler face.
• Check subsequently for leaks.
Gas train

on the flange of gas train B.
• Install support PG 21 (drawing)
• When fitting gas train, valve coils must
be in high vertical position.
Important
When using a left-mounted VGD gas
train, the SKP75 regulator should pivot
by 180°. To that end :
• Remove regulator SKP75.
• Remove connector (3P + T) on the
side of the regulator, and put it back
together on the opposite side.
Seal off the former position of the
connector.
• Reassemble the regulator after it has
pivoted by a half turn (180°).
