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. The
pressure should be checked when the unit is installed and each time it is serviced to ensure
that it is correct.
Contact Rinnai before attempting to alter the gas pressure if you are
unsure of what to do. Incorrect adjustment can void the warranty.
1. Turn 'OFF' the gas supply.
2
. Turn 'OFF' 23
0
V power supply.
3
. Remove the front cover from the appliance.
4. Check gas type dip switch no.1 of SW2 is in the correct position for the type of gas (Nat.
or LPG)* you are using. See Fig. 1
5
. Attach pressure gauge to burner test point. (Fig. 2)
6
. Turn 'ON' the gas supply.
7
. Turn 'ON' 23
0
V power supply.
8
. If remote controllers are fitted, turn the unit 'ON' at the controller and select a maximum
delivery temperature.
9. Open a hot water tap fully.
(CAUTION: Ensure building occupants do not have
access to hot water outlets during this procedure.)
Wait for the unit to light.
* 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.
