6.6 Locating the appliance
▶ Remove packaging, observing all notes and symbols.
▶ On the rating plate, check the identification of the target country and
suitability for the gas type supplied by the local gas utility company
( page 8).
Removing the cover
To remove the cover:
▶ Pull the front panel towards you from the top right and left edge to
release the ball catches [1] from their retainers [2]
▶ Lift the front panel off the lower mounts [3] and place in a safe
location away from the work area
Fig. 21 Remove the cover
6.6.1 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
Fig. 22 Levelling the boiler
NOTICE: Residue, metal shavings, and contaminants in
the piping can damage the appliance.
▶ Flush the piping thoroughly and completely to
remove all residue.
▶ Follow the instructions with respect to water quality
( Chapter 6.1, page 30).
NOTICE: Damage caused by insufficient load bearing or
unsuitability of the boiler room floor
▶ Ensure the floor area is suitable for installing a boiler
and can take the “wet weight” of the appliance.
NOTICE: Damaged caused by mechanical strain on the
hydraulic and flue gas connections when adjusting the
position of the appliance.
▶ Do not apply any strain the connections when
adjusting the boiler position
