Clearances required for maintenance
UNICA MAX 35C

Sides
2mm*
Top
100mm** from casing or 25mm above flue elbow (whichever is applicable)**
Bottom
100mm^
Front
450mm^^
* It may be necessary to remove adjacent components if component removal/replacement is required
** Consideration should be given to providing reasonable clearance for the insertion of a FGA probe.
^ This can be reduced to 4mm if a removal panel enables the required 100mm
^^ When installed in a cupboard, this dimension can be reduced to 4mm provided that the required 450mm is available when the door is opened/
removed.
