Start-up instructions4
8. Turn gas valve ON/OFF switch counterclockwise to
ON position.
9. The automatic igniter must generate sparks towards
the pilot burner. The pilot flame must appear and
then ignite the main burner. If the main burner does
not ignite, close the gas valve. Disconnect heating
system from the power supply and inform your
customer service technician or gas company.
10. If the main burner has ignited, the gas valve must be
checked for leaks with soap solution. If no leaks are
found, continue with step 12. If leaks have been
found, switch ON/OFF switch on gas valve
clockwise to the OFF position. Disconnect heating
system from the power supply and set the
thermostat to the lowest setting.
11. Seal leaks. Repeat steps 1 and 2 (regardless of the
control in use).
Caution:
With aquastat control continue with steps 3 and 4,
with the Logamatic 2107 continue with steps 5
and 6.
Then repeat steps 7 to 10 regardless of the control
in use.
12. Check the gas supply pressure at the connection
while the boiler is operating. The supply pressure for
natural gas must be between 7" and 10.5" W.C. and
between 11" and 13" W.C. for propane gas. Record
the measured values in the commissioning protocol
in the installation and maintenance instructions.
13. Check manifold pressure. The manifold pressure
must be set in accordance with the values in
Î Tab. 2. To set the manifold pressure the cover
(Î Fig. 11) on the gas valve must be removed. Turn
the adjustment screw clockwise to increase the
pressure and counterclockwise to reduce the
pressure. This setting must be adjusted while the
boiler is operating.
14. Record the set value in the commissioning protocol
of the installation and maintenance instructions and
screw the safety screw (Î Fig. 11 page 12) into the
gas valve again.
