Boiler face
· Prepare face following the enclosed
space requirement diagram.
· If required, insert face counter-plate

· Fill in space 1 with recommended
heat-resistant material or material
supplied by the boiler manufacturer.
m
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 for possible leaks.
Gas train
· Check presence and position of
gasket on the flange of manifold 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 SKP70 regulator should pivot
by 180°. To that end :
· Remove regulator SKP70.
· Remove connector (3P + T) on the
side of the regulator, and put it back
together on the opposite side.
m
Seal off the former position of the
connector.
· Reassemble the regulator after it
has pivoted by a half turn (180°).
Motor-pump unit GMP

· Connect the ignition cables on both
transformers.
· Close the body of the burner with
removable pin E.
· Fix safety screw D.
· Fit the "fuel oil" tubes between the
valves and the nozzle line T.
Connecting the gas pressure take-offs
· Connect coupling pF of the valve to
the coupling labelled pF on the
combustion head with two reversible
preformed tubes (right - left) ,which
are connected up by a coupling (see
drawing).
· Crimp the rings on the tubes.
· Connect the coupling labelled pL to
the coupling pL of the valve.
· Tighten nut by hand.
· Check for possible leaks.

on valve MBVEF, and the two
screws 1 and 2 on valve VGD.
· Make sure the two O-rings are
available on the VPS.
Q
· Fasten the VPS with the 4
self-forming screws
· Connect the cord of plug 7P
according to the electrical diagram.
· Connect plug 7P to the VPS.
· Check for possible leaks
Q Case of valve VGD20 : proceed as
indicated at the beginning of the earlier
paragraph, then :
· Fit the tubes and the terminal block
supplied.
