Grant Euroflame Condensing External Modules
1 A 230/240 V ~ 50 Hz mains supply is required.
The boiler must be earthed.
2 The supply must be fused at 5 Amp and there must
only be one common isolator for the boiler and
control system, providing complete electrical
isolation.
3 A fused double pole switch or a fused three pin
plug and shuttered outlet socket should be used for
the connection.
4 The power supply cable should be at least 0.75 mm²
PVC as specified in BS 6500, Table 16.
5 All the wiring and supplementary earth bonding
external to the boiler must be in accordance with
the current Wiring Regulations.
6 Any room thermostat or frost thermostat used must
be suitable for use on mains voltage.
7 The boiler requires a permanent mains supply, do
not interrupt it with any external time control.
8 In the event of an electrical fault after installation
of the boiler, the following electrical system checks
must be carried out:- Short circuit, Polarity, Earth
continuity and Resistance to earth.
The boiler does not come fitted with a frost thermostat.
If there is a need for a frost thermostat, the installer
should fit one within the casing.
4 - GENERAL BOILER INFORMATION
1 The Euroflame condensing module must stand on a
solid, level surface capable of supporting the weight
of the boiler when full of water, e.g. a prepared
concrete standing, paving slabs bedded down on
sand/cement, or similar.
2 The Module can be installed either against the building
or 'free standing' some distance away from the building.
3 The Module must be positioned such that the
required clearances from the low level flue outlet,
as shown in Fig. 7, are achieved.
4 Adequate clearance must be left around the Module
for servicing. In particular, a minimum clearance of
600 mm above the Module for removal of the top
panel and 600 mm at the opposite end to the flue outlet
for access to the burner.
Sufficient clearance is required at the rear of the
boiler to allow the rear panel to be removed for
access to the condensate trap.
5 The flue terminal must be a minimum distance of
1.8 m from an oil storage tank.
The flue terminal should be positioned so as to
avoid products of combustion accumulating in
stagnant pockets around the building or entering
into buildings.
