3.6 FROST PROTECTION MODE

The electronic boiler management system includes a "frost protection" function for the heating system which, when delivery
temperature falls below 41°F (5°C), lights the burner until a delivery temperature of 86°F (30°C) is reached.
This function is only operative if the boiler is electrically powered and there is gas with normal system pressure and the flue is not
blocked.
