The boiler settings, such as burner pressure and adjustment of the air quantity are
unnecessary in most cases, due to the fact that the boiler operates with a zero pressure
control. This means the correct gas quantity is controlled by the suction operation of
the fan. The
fi
ne adjustment of the zero pressure, which is carried out at the factory
is once-only, which means that adjusting of this value is unnecessary. Only in case of
replacing of the gas valve, venturi and/or fan will the zero pressure adjustment have
to be checked and, if necessary, adjusted to the right value.
The venturi must always be checked and adjusted when it is out of range see
section 13.3 on O
2
adjustment.
Always check the installation of all parts through which gas fl ows (by bubble
test using leak-search spray).

fi
red for the
fi
rst time:
1. Remove the vent pump screw
2. Use a small
fl
at head screw driver to ensure the impeller spins freely.
3. When the impeller spins freely and water exits though the vent port the pump is
ready for operation.
4. Replace the vent screw
During the commissioning of the boiler the Rinnai Installation, Commissioning, and
