Failure to connect the overflow-outlet to a permanent waste or drain, could lead to property damage from
flooding.
If in all circumstances, it is absolutely not possible to direct the boiler overflow-outlet to a permanent waste
or drain, then the mains water supply to the boiler should be isolated and the unit switched off whenever it is
left unattended for long periods (e.g. overnight).
Whilst every reasonable precaution is taken to prevent an overflow, Instanta cannot be held responsible for
any damage caused as a result of incorrect installation or blockage of the overflow or failure to direct the
overflow to a safe outlet.
VENT PIPE:
A small silicone rubber tube connects the tank-
lid to the back panel. Ensure this is connected (and hasn’t come
off in transit) and that the outlet fitting in the back-panel is not obstructed.
e) FITTING CASE:
-
Attach the Earth wire connection to bottom of stainless steel boiler-case using M4 screw & washer
supplied.
-
Offer up the case to the wall-mounted boiler and plug-in the two communications-leads (from circuit
board to LCD screen and from circuit board to push-button) located on inside of boiler-case.
-
With the communications leads and Earth wire connected, carefully position the boiler case onto the
wall-mounted boiler chassis, ensuring that the water-valve outlet pipe locates into the slot-opening in
the plastic cup aperture.
-
Secure case in position using M4 screw (supplied) at top and bottom of the case.
