vapour and quite normal. The boiler requires a drain to be permanently connected,
your installer has done this, it must not be disconnected or removed. The Installer
should also have left you your Logbook. The Gas Safety (Installations

ELECTRICAL SUPPLY TO YOUR BOILER
The boiler must be connected to a 230v ~ 50 Hz supply with a 3 Amp fuse rating.
THE APPLIANCE MUST BE EARTHED.
TO IGNITE YOUR BOILER
With the Electricity supply switched on, the power lamp will be on. When the
system programmer and thermostats are in a demand position and the front panel
boiler thermostat fully clockwise, the boiler running lamp will be lit and the boiler
willstartautomatically. The running lampwillgooutwhenthesystemthermostats
are satisfied or if the programmer is off.
If the boiler fails to start and the lockout lamp is lit reset by turning the boiler
thermostat to off then back on again.
If the boiler does not start after using the reset allow the boiler to cool, then reset
again. Ifthisstilldoesnotsucceedingettingtheboilertorun,orifafaultissuspected
turn the boiler and supply off and call the assistance of a Corgi registered Engineer.

The variable thermostat on the front panel adjusts the temperature of the water in
the system, the further clockwise, the hotter the system will be. For maximum
efficiency use the lowest setting that still obtains comfortable room temperatures,
butstill provides satisfactoryhot water performance. Fullyanti-clockwise will switch
the boiler off.
Please note, it is normal for the boiler to switch on and off under the
control of the system and its own thermostat. Due to a built-in delay
timer, there will be a few minutes delay between the boiler Control
Thermostat being turned on, and ignition. This is indicated by a slow
flashing of the running lamp.
