▶ Turn on high volume of hot water flow (at least 15 l/m) and
burner will light. If heater display reverts to P2, open more
hot water fixtures to allow sufficient flow. Press
P1 reappears on the display.
▶ Operate all other gas appliances on same gas piping system
at maximum output.
▶ Record lowest operating gas pressure reading in Table 7 .
Gas pressures lower than 2,0 kPa for Natural Gas or 3,0
kPa for Butane will result in insufficient degree rise to the
hot water being used, reduced hot water volume, possible
error code faults and must be corrected.
Check gas pipes dimensions.
