Regulations applicable in Scotland, with
respect to the installation of the combination
boiler in a room or internal space containing
a bath or shower.
Where a room sealed appliance is installed
in a room containing a bath or shower, any
electrical switch or appliance control, utilising
mains electricity should be situated so that it
cannot be touched by a person using a bath
or shower.
A compartment when used to enclose the
combination boiler MUST be designed and
constructed specifically for this purpose.
An existing cupboard, or compartment, may
be used provided it is modified accordingly.
Samples of the HE 25/30 S Compact combi
boiler have been examined by CERTIGAZ
notification body, and are certified to comply
with the essential requirements of the gas
appliance.
Directive 90/396/EEC, the Low Voltage.
Directive 72/23/EEC and shows compliance
with the Electro Magnetic Compatibility.
Directive 89/336/EEC and are therefore
permitted to carry the CE Mark.
The appliance has been tested and approved
by the WRc as meeting the requirements of

Bylaws Scheme - Approved Products.
4.6 GAS SUPPLY
A gas meter is connected to the service pipe
by the Local Gas Supplier or the Local Gas
Supplier contractor. An existing meter should
be checked preferably by the Gas Supplierto
ensure that the meter is adequate to deal
with the rate of gas supply required for all
appliances it serves. Installation pipes should
be fitted in accordance with BS 6891:2015.
Pipework from the meter to the boiler must be
of adequate size
(22 mm) min to within at least one metre of
the boiler, (15 mm) min. can then be used
for remaining pipe work to the appliance.
A smaller size than the boiler inlet gas
connection should not be used. The complete
installation must be tested for soundness as
described in the above code.
.
N.B. It is the responsibility of the Gas Installer
to size the gas installation pipework in
accordance with BS 6891:2015. Whilst the
principle of the 1:1 gas valve ensures the
Ravenheat range is able to deliver the full
output at an inlet pressures as low as 14
mbar, other gas appliances in the property
may not be as tolerant.
When operating pressures are found to be
below the minimum meter outlet of 19 mbar
these should be checked to ensure this is
adequate for correct and safe operation.
