Baxi POWER HT+ Series - Electrical Power Supply; Circulating Pump

The boilers are preset to run on G20 gas (gas H) and can be adapted to
run with the following gases:
G25 (gas L),
G25.1 (gas S),
G27 (gas Lw),
G31 (gas P),
Important
To use a different type of gas, contact an approved assistance
service.
5.2.3 Electrical power supply
Power supply voltage 230 V AC/50 Hz
Caution
Please ensure the polarities shown on the terminals are followed,
i.e live (L), neutral (N) and earth ( )
5.2.4 Circulating pump
The boiler's water flow rates must be higher than or equal to the
specifications in the table below:
Tab.13 Water flow rates in the boiler
Boiler model Working flow rate with the low-loss header kit: minimum flow rate (litres/
hour)
POWER HT+ 1.130 2250
POWER HT+ 1.150 3000
POWER HT+ 1.200 3500
POWER HT+ 1.250 4500
1 Q flow rate (litres/hour)
2 H pressure in millibar (mbar)
3 Operating water flow rate at nominal heat output = 3730 litres/hour
where ∆T = 30°C
4 Operating water flow rate at nominal heat output = 5600 litres/hour
where ∆T = 20°C
5 Operating water flow rate at nominal heat output = 7500 litres/hour
where ∆T = 15°C
ΔT Temperature difference between the flow water and the return
water in the boiler
