17. Gas Pressure Setting Procedure
The regulator on the Infinity is electronically controlled and factory pre-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.
1) Turn 'OFF' the gas supply
2) Turn 'OFF' 240V power supply.
3) Remove the front cover from the appliance.
4) Check gas type switches (fig. 1) are in the correct
position (dipswitch 1 of SW2 ‘ON’ = NG ‘OFF’ = LPG).
Note: ‘ON’ towards front, ‘OFF’ towards rear.
5) Attach pressure gauge to burner test point, located on the
gas control. (fig. 2).
6) Turn 'ON' the gas supply.
7) Turn 'ON' 240V power supply.
8) If remote controllers are fitted, turn the unit 'ON' at the
kitchen controller, select the maximum delivery
temperature of 55°C and open a hot water tap fully.
(
CAUTION: Ensure building occupants do not have
access to hot water outlets during this procedure).
9) Set the Infinity to 'Forced Low' combustion by setting
No. 7 dipswitch of the (SW1) set of dipswitches to 'ON'.
(fig. 3).
10) Check the burner test point pressure.
11) Remove rubber access plug and adjust the regulator
screw on the modulating valve (fig. 4) as required to the
pressure Table 1. Replace rubber access plug.
12) Set the Infinity to ‘Forced High’ combustion by setting
both No. 7 and No. 8 dipswitches on the bottom (SW1)
set to ‘ON’. (fig. 5). Ensure maximum water flow.
13) Check the burner test point pressure.
14) Adjust the high pressure Potentiometer (POT) on the
Printed Circuit Board (PCB) as required to the pressure
shown Table 2. (fig. 1).
