5-4.1 Floor Standing External Boilers
The external floor standing range of Boilers are based on the Internal Floor Standing range.
They can be positioned remote from the dwelling or against an external wall of the
dwelling.
Cables must be suitable for outside and/or underground use.
5-4.2 Heating Connections
The heating flow and return pipes should enter the Boiler casing via the two side ducts and
connect to the Boiler flow and return spigots. Suitable flexible connectors can be used but
MUST be 22mm bore minimum.
Connecting the flow to the right hand spigot will give the maximum flow through the Boiler
but this is not essential for satisfactory operation - see fig 5-4a.
5-4.3 Base
A suitable base should be provided, this must be level, impervious to kerosene and non-
combustible.
5-4.4 Oil Connection
Floor Standing External Boilers are supplied with a pump set for single pipe oil system.
Fig. 5-4b shows a typical oil pipe arrangement.
The oil pipe, fire valve capillary and electric cable should be arranged to enter the Boiler
casing via either of the two side ducts.

5-4.5 Fitting the Flue
Fit flue as shown in fig. 5-3d. The outlet can be orientated in any direction except directly
to the wall. Water entering the flue is not a problem as this will drain to the condsensate
drain.
5-4.6 Frost Protection
All External Boilers have a frost thermostat fitted as standard, this must be correctly wired
to provide frost protection - see wiring diagrams Section 11.
A suitable antifreeze must also be used in applications where freezing can occur and
should be considered for all systems.
5-4.7 Rodent Intrusion
Boilers installed in situations where rodent intrusion is possible, all pipe/cable entry holes
of the Boiler must be covered, after installation, to prevent rodents entering the Boiler
casing.
