5.2.2 Positioning the appliance
The boiler must be adjusted to be level. This ensures air can escape from
the heat exchanger and condensate drains freely.
▶ Place boiler in its final location
▶ Release the locknuts on the boiler feet
▶ Adjust the boiler feet until the boiler is level vertically and
horizontally, check using a spirit level
▶ Secure in position with the locknuts

room for access to the pipe work.
• Do not cross a pipe over another.
