Gas Pressure Setting - Rinnai REU-VR2632FFUD - 26i Installation And Use Manual

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' 230V power supply.
3. Remove the front cover from the appliance.
4. Check gas type switches no.1 and no.2 of Dip SW2 are in the correct position for the type of gas
used. See Fig. 1

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.
