When installing the boiler as a Type C53 appliance, it should be noted that the terminals must
not be installed on opposite sides of the building.

If the flue temperature sensor is not fitted, the flue gas temperature may exceed the maximum

temperature rating of the flue and can lead to severe personal injury, death or substantial
property damage.
