What it is

The Andrews 7709357 is a 22mm gas manifold pipe intended for water heaters fitted with twin heat exchangers. It forms part of the gas train, feeding gas to the twin heat exchanger assembly. It is used across the Andrews Maxxflo EVO range.

  • Sooting, poor combustion or an unstable flame at the burner
  • Whistling or abnormal noise from the gas train
  • Repeated lockouts or ignition faults linked to the gas supply

Before you order
