installations.
Where a room sealed appliance is installed in a room containing
a bath or shower, any switch or appliance control using mains
electricity must NOT be able to be touched by a person using the
bath or shower. The IP rating of the appliance may only allow it
to be located in specific 'zones'. Refer to, in GB, Electrical
Regulations 16th Edition.
The appliance is NOT suitable for external installation
No special wall protection is required. The wall must be able to
support the weight of the appliance. Refer to Table 4.
The specified clearances must be available for installation and
servicing. Refer to Table 8 and Fig.3, 4.
The appliance can be installed in a cupboard/compartment to
be used for airing clothes providing that the requirements of
BS6798 and BS5440 Part 2 are followed. Refer to Section 2.5.
The airing space must be separated from the boiler space by a
perforated non-combustible partition. Expanded metal or rigid
wire mesh is acceptable provided that the major dimension is
less than 13mm. The clearance between the front of the
appliance and the cupboard or compartment door should be not
less than 75mm.
LPG Installation. Refer to Section 1.8.
The flue system must be installed following the requirements of
BS5440: 1. In Eire the flue termination must be sited as
described in Table 5 of the current edition of IS 813.
Standard horizontal flue kit length is 275 – 725mm with
extension kits for flues upto 4m for natural gas and 2.5m for LPG.
The terminal must not cause an obstruction or the combustion
products a nuisance. Under some conditions the terminal might
steam and positions where this might be a nuisance should be
avoided. Refer to Fig 8.
If the terminal is less than 2m above a surface to which people
have access then a guard must be fitted. The guard must be
evenly spaced about the terminal and fixed with plated screws.
A Type K2 guard is available from Tower Flue Components, Vale
