NB: If the answer is NO to any of the points below then read the adjacent comments for further guidance.
Is the gas supply natural gas?
Is the boiler fitted to a fully pumped system?
Is the flow and return connection on the
left hand side of the boiler? (looking at the boiler)
Does the system incorporate a bypass?
Is the boiler installed to a Class 1 Flue?
Check builders opening (see comments) .
Is an existing fire surround installed? (see comments).
Does the existing fire have an electric light effect?
Is there a 13 amp socket in close proximity to the
existing fire and boiler location? (see comments)
Will there be a clearance of 150mm from the
BBU flue terminal to an adjacent terminal?
Measure and check the flue length and its path.
(see comments) .
Is there a waste drain point close to the boiler
location? (see comments) .

Yes No Comments
No LPG model currently available.
If the heating system is a gravity hot water pumped
heating system it must be converted to a fully
pumped system Y or S Plan.
If the existing pipe work is connected from the right
hand side then the optional extra pipe work kit may
be required to facilitate installation.
A pressure operated bypass will be required if the
minimum flow rate is lower than 8.3 litre/minute.
225mm x 225mm (9" x 9") brick or 175mm (7")
salt glazed lined flue is required.
570mm (22") height, 584mm (23") width, 305mm
(12") depth is the minimum size of the builders
opening. If only the minimum depth is available a
range of spacer kits or rebated surrounds are
available for the firefront (see page 13 of the
Baxi Bermuda BBU HE brochure).
The minimum fireplace opening size is 558mm
height (22") x 406mm width (16") If installing with
minimum fireplace dimensions provision will need to
be made for access to the gas service cock and inlet
test point. The surround will need to be removed to
allow access for installation of the BBU.
The boiler will require a 3 amp permanent live as
well as a switched live feed from the same source to
operate satisfactorily.
The fire will require a separate13 amp supply.
150mm clearance is required from the BBU
flue terminal to an adjacent terminal.
There are 2 concentric flue system kits available,
10 metre and 12.5 metre. These lengths may be
cut shorter but cannot be extended beyond their
specified length.
The boiler incorporates a sump pump for the
removal of condensate. The pump can lift
condensate vertically 2.5 metres (as measured from
the case outlet of the boiler.) Any horizontal run
should be kept as short as practicable with a
miniumum of 3 degrees on all gravity falls.
For guidance on maximum horizontal runs and
number of elbows please refer to Baxi's Installation
