3.4 SAFETY DEVICES
Safe operation under various conditions is ensured by the
following controls:
Water flow switch that monitors water flow in the
o
heating system and will prevent operation in case of
a blockage, if the system flowrate is below the
permitted level, error E3 will appear.Installation of a
system by-pass may be necessary (see 7.3HEATING
SYSTEM FLOW SWITCH – E3 ERROR & SYSTEM
BY-PASS REQUIREMENTS).
Hot water high limit safety thermostat will prevent
o
operation if the temperature exceeds 80ºC. It
requires re-setting manually.
Heating system high limit safety thermostat will
o
prevent operation if the temperature exceeds
100ºC. It requires re-setting manually.
Hot water pressure relief valve will discharge to
o
relieve excess pressure at 7 bar.(Requires piping to
a safe external discharge point.)
Heating system pressure relief valve will discharge
o
to relieve excess pressure at 3 bar. (Requires piping
to a safe external discharge point.)
4 INSTALLATION
IMPORTANT PRE- INSTALLATION POINTS
i
In order to ensure the successful installation
and operation of your Gabarron boiler please
consider the following points before commencing.
SITING THE BOILER
Wall and fixings must b
WARNING
support the total weight; CMX boiler when full is
120 kg, CM boiler when full is 50 kg.
Allow sufficient clearance and access for operating,
maintenance and repair work.
Boiler must be protected from any water, moisture, or
dampness.
Installation must comply with regulations for electrics if
installed in bathrooms.
Boiler electrical protection rating is IP20/IP2X. This boiler is
not designed to be installed in the open air.
The boiler must be installed in the upright position.
ELECTRICAL POWER SUPPLY & WIRING
WARNINGBefore carrying out any work inside
the boiler and obtaining access to terminals, all
supply circuits must be disconnected.
WARNINGEarth the appliance. If the appliance is
not earthed, it may hold voltage if a defect occurs.
Competency for electrical installation is required.
The power supply must meet the capacity for the heat
output required plus all other appliance that may be
supplied.
The cable, MCB and RCD must be of sufficient capacity to
carry the required load.
i
Boiler is supplied set at maximum output and must be
adjusted to suit the incoming supply before being
switched on. (See 5.1 LIMITING BOILER MAXIMUM
OUTPUT).
HEATING SYSTEM & CONTROLS
Any existing system must be suitable for sealed system
operation at up to 3bar pressure and may require
flushing/cleansing.
A combi filling loop, isolation valves and drain point are
required.
A time clock/room thermostat should be
installed.(Necessary to activate automatic power
modulation)
System by-pass will be required for fully TRV systems.
The correct heat requirement for the dwelling should be
calculated.
