INSTALLATION SCHEMATICS
SEALED SYSTEM
Sealed System Kits are available from
Advance Appliances and can be sited
anywhere in the open pipework of
the system
The eGlow boiler can only be configured into a sealed system. A sealed system kit can be
purchased from Advance Appliances to make the job simple. An 8 litre expansion vessel is
supplied with each kit but it should be noted that systems with high water content may
require larger vessels. All heating systems must be isolated from the mains water supply
after the system is filled.
ELECTRICAL CONNECTIONS
THIS APPLIANCE MUST BE EARTHED
The appropriate current regulations and best practices must always be followed. Installation
must be carried out by a competent and qualified tradesman. Use off peak supplies where
possible to reduce running costs.
Check the incoming supply meets the minimum requirements of the appliance and utilise a
double pole RCD capable of breaking the full current load. Remember that the full house
loading must be taken into consideration when calculating mains demand. Refer to IEE
regulations for wiring size to the appliance. The mains feed goes directly to the terminal
block identified on the schematic (on page 8) and the boiler itself. The earth must be
connected to the marked point.
Standard switching is maintained through the controls, zero voltage switching is used and a
separate power supply for programmer and room thermostat (if digital) should be used. In
some cases this may be a battery or a mains charger with rechargeable cells in the
programmer. This control circuit is identified on the schematic (on page 8) and will switch
the boiler internally.
In the case of a combined hot water and heating system a Y plan or similar can be used
with a three port motorised valve, in which case a separate mains supply will be required
to operate the valve which will be switched via a suitable programmer NOT the boiler PCB.
Use a relay if any voltage is present.
Always consult manufacturer's requirements and recommendations for controls, the above
advice is of a general nature only.
