PRE-INSTALLATION CHECKS
3.5 All open flued appliances can be affected by temporary
atmospheric conditions which may allow fumes to enter the
boat. An electronic carbon monoxide detector conforming
to the latest edition of BSEN50292 must be fitted and
maintained.
3.6 Failure to safely install the appliance could endanger the
boat and persons on board.
2.7 Ventilation requirements in the UK are as shown in the table
below:
A) Traditionally Built Homes
— Where the leakage is greater than 5m 3 /hour/m 2 .
— Ventilation normally required = 550mm 2 per kW output
over 5kW

2.8 Permanent air vents should be non-adjustable and positioned
where they are unlikely to be become blocked.
2.9 If vents open into adjoining rooms or spaces there must be an
air vent of at least the same size direct to the outside.
2.10 Site the vents where cold draught is unlikely to cause
discomfort. This can be avoided by placing vents near ceilings
or close to the appliance, see diagram below.
2.11 Extractor fans or cooker hoods must not be placed in the
same room or space as this can cause the appliance to emit
fumes into the room.
2.12 Increase air supply provisions where a room contains multiple
appliances.
2.13 If any checks reveal problems do not proceed with the
fitting of the appliance until they have been rectified.
3. FITTING APPLIANCES ON A BOAT
3.1 If an appliance is to be fitted in a boat it must be done in
accordance with the latest edition of BS 8511 (Code of
Practice for the Installation of Solid Fuel Heating Appliances
on Boats). The Code covers the design, installation
and operation of solid fuel heating appliances that are
suitable for fitting into inland waterway boats, and gives
guidance on product selection, design considerations,
installation requirements, inspection and testing, as well as
maintenance and safe use tips.
3.2 Consideration should also be given to the requirements of
the Boat Safety Scheme (BSS) to ensure the boat's insurance
remains valid.
3.3 The appliance should only be installed by a competent
person with experience of the latest edition of BS 8511 and
the Boat Safety Scheme (BSS).
3.4 Secure the product to a suitably constructed non-
combustible hearth.
