Immergas Victrix fault MA

Manual activation of operating devices for verification

Gas boiler

What it means

Allows technician to manually activate individual operating devices (fan, circulator, 3-way valve, configurable relay) without starting the appliance normally, in order to verify correct operation of each component.

Likely causes

  1. Dirty burner
  2. Clogged primary heat exchanger
  3. Incorrect combustion parameters
  4. Intake-exhaust terminal not correctly installed
  5. No gas
  6. Condensate drain clogged
  7. Drain trap not yet filled with condensate on first start-up, allowing combustion products to escape via condensate drain
  8. Long period of inactivity causing rotor to seize

Where to start

  1. Access special functions as described in Paragraph 3.12 and select 'MA' function
  2. Select Fan (Fn) to bring fan to ignition speed; use up/down buttons to increase/decrease fan speed
  3. Select Circulator (Pu) - circulator brought to maximum speed, relative speed shown on display, adjustable with up/down buttons

Safety: Isolate gas and power before you open the case. If you have been into the gas side, do a tightness test, and a combustion and flue check before you hand back. Gas Safe (UK) or RGI (Ireland) work only.
