Pipe installation
Transport and installation
The electric boiler must be transported and stored dry.
EVC 13 is designed to be positioned on top of an electric
water heater of the NIBE COMPACT type. Ensure that any
anode in the water heater is accessible. For installation
and access for service, there must be space of approx.
30 cm above and approx. 60 cm in front of the boiler.
NOTE
EVC 13 must be installed horizontally, at least 50 cm
from the floor. To ensure sufficient ventilation for the
electric components, there must be an air gap of at
least 10 mm under the bottom plate of the boiler.
Connections
Pipe installation must be carried out in accordance with
current norms and directives. The boiler is equipped with
R20 connections, externally threaded. Shut off valves
should be installed outside EVC 13 to simplify any future
service.
NOTE
The pipe installation must be flushed, so that any
contaminants do not damage the equipment.
Overflow pipe
The overflow pipe must be routed according to current
norms and directives.
The overflow pipe from the safety valves must be routed
to a floor drain to prevent hot water splashes when
checking the valves or when bleeding the boiler. The outlet
of the overflow pipe must be visible.
When installing a NIBE COMPACT water heater, the over-
flow pipe for the electric boiler must be routed straight
down through the top panel of the water heater.
Tapping valve
EVC 13 is equipped with a drain valve (51) on the boiler
with a R15 ( 1/2” ) hose connection. To drain the boiler,
remove the cap for the valve and screw the hose connec-
tion into position. Open the drain valve. The safety valve
(52) is then set to the open position for air supply. The
drain valve for the radiator system must be located in a
suitable place.
Circulation pump
The boiler has a circulation pump located in the return
line. The pump capacity is set using the diagram. To pre-
vent cavitation in the pipes the flow must not exceed 1700
l/h.
