Installation
Gas and electrical connection
Connecting pressure tubes
Gas connection
Connection of the gas distribution
system to gas manifold must be
performed by a technician.
Pipe section must be calculated so that
load loss does not exceed 5% of
distribution pressure.
External filter must be
horizontally
mounted on valve with a
clean
tube and
the cover placed in a
vertical
position to
guarantee maintenance.
Any other assembly is forbidden.
The quarter-turn hand-operated valve
(not supplied) must be mounted
upstream and as close as possible to the
gas manifold.
Threaded fittings used must comply with
current standards (tapered external
thread, parallel internal thread) and all
threads rendered leak-proof.
This type of assembly is not removable.
Allow enough space for access to set
the gas pressure switch.
Pipes must be drained upstream of the
quarter-turn hand-operated valve.
Connections performed in situ must be
leak-tested using foam designed for this
purpose.
No leak should be found.
Electrical connection
The electrical characteristics such as
voltage, frequency, power, are
mentioned on the identification plate.
Minimum conductor section: 1.5mm²
Delayed-action minimum protection
device: 6.3A
Refer to the wiring diagrams for the
electrical connections (diagram
enclosed with the burner and diagram
screen printed on socket 7 P and 4 P for
the controller thermostat).
The gas manifold is connected through
prewired connectors.
• Connect electrical plate standby points
on valve.
• Secure the cables using the clamps
supplied.
Optional :
External connection :
- of an alarm between S3 and N
- of one (or more) hour meter between
B4 and N to totals the operating hours,
and between B5 and N to count the
operating hours at nominal flow rate.
Connecting pressure tubes pF-pL
• Remove cable clamp
9
.
• Cut the studs on the two moving parts
to insert electric cables
C
into a
mortise and the two flexible tubings
pF
and
pL
into the other notch.
• Tighten the cable clamp on the plate
without locking it.
• Secure connections
pF
and
pL
between the valve and the gas supply
cover along with the identified flexible
tubings.
• Tighten the nuts by hand.
• Lock cable clamp
9
.
• Check the tightness.
