20 CONDENSATE DRAIN
Each module is provided with a condensate trap, the pipe size from the
trap outlet is 22mm.
The routing of the drain must be made to allow a minimum fall of 1 in
20 away from the boiler, throughout its length.
1.
Fit the provided trap/s to each module/s and support with the
bracket provided.
2.
Connect the rubber elbow (provided) to the trap top connection.
3.
Connect a condensate drain to each trap outlet and pipe to a
suitable drain point preferably within the building.
IMPORTANT.
Any external runs must be kept to a minimum and
insulated to avoid freezing in cold weather causing blocking.
All pipe work and fittings must be plastic. No other materials may be used.
19 GAS CONNECTION
The header gas supply pipe terminates in a Rp 1 ¼” female thread
connection (250 model), a R2” male taper connection (500 & 750 models)
and a R2 ½” male taper connection (1000 model)
A minimum working gas pressure of 17mb must be available at the boiler
inlet with the boiler firing.
Fit a gas supply pipe not less than the sizes by boiler output stated
above.
All gas supply pipe work must be independently supported.
21 ELECTRICAL CONNECTIONS
Warning
.
This appliance MUST be earthed.
A mains supply of 230V 50Hz is required (Live, Neutral and
Earth). An additional Earth is required to be connected to the
Master Module chassis Earth Bonding point on the rear RHS
vertical strut lower connection. See Frame 12, Boiler Assembly.
Where more than one module is to be installed, i.e. Evomod
500, 750, 1000 each module chassis must also be bonded
together using the supplied earth bonding straps.
Wiring external to the boiler MUST be in accordance with
the current I.E.E. (BS7671) wiring Regulations and any local
regulations. For Ireland reference should be made to the
current ETCI rules for electrical installations.
Connection should be made in a way that allows complete
isolation of the electrical supply - such as a double pole
switch, having a 3mm (1/8") contact separation in both poles.
The means of isolation must be accessible to the user after
installation.
When making mains electrical connections to the modules it
is important that the wires are prepared in such a way that the
earth conductor is longer than the current carrying conductors,
such that if the cord anchorage should slip the current carrying
conductors become taut before the earthing conductor.
WARNING. Sensor cables must be separated from cables in the
230V circuit. Refer to Frame 25 for terminal connections.
