GAS PRESSURE SETTING
The working gas pressure on the water heater is electronically controlled and factory set.
Under normal circumstances it
does not
require adjustment during installation.
Perform this procedure only if the unit is not operating correctly and
all
other possible
causes for incorrect operation have been eliminated.
Contact Rinnai before attempting to alter the gas pressure. Failure to do so could void
the warranty.
1. Isolate gas supply.
2. Cut off power supply.
3. Remove front cover (2 screws in the lower part
of front panel) (Fig.1).
4. Disconnect connector of operating controller
cable (Fig.2).
5. Check gas type dip switches no. 1 and no. 2
on PCB are in the correct position for the type
of gas (Nat. or LPG)
*
you are using (Fig.3).
6. Remove pressure point screw and o
-
ring from
pressure point on manifold and connect digital
manometer (Fig.4).
7. Connect power supply and gas.
8. Change nr. 6 switch on PCB to ON position
(Fig.5) to force appliance to low forced
combustion and open a hot water tap.
* Note: simply changing the position of the dip switches will not convert the unit from
one gas type to the other. The conversion procedure requires a change of
injector manifold. Contact Rinnai or your supplier.
