Control of water temperature
The boiler controls the central heating radiator temperature to a
o
maximum of 80 C, adjustable via the temperature control (A).
The Logic Heat is a high efficiency condensing boiler which is
most efficient when operating in condensing mode.
The boiler will operate in this mode if the temperature control (A)
is set to the 'e' position (economy mode). This control should be
set to maximum for very cold periods
To shut down the boiler
Set the mode control knob to OFF.
To relight the boiler
Repeat the procedure detailed in 'To light the boiler'.

Frost protection

If no system frost protection is provided and frost is likely during
a short absence from home, leave the heating controls (if fitted)
at a reduced temperature setting. For longer periods, the entire
system should be drained.
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF at the time switch (if
fitted) ONLY. The mains supply should be left switched ON, with
the boiler thermostat left in the normal running position.

Blockage of the condensate drain, caused by debris or freezing, can
cause automatic shutdown of the boiler.
If freezing is suspected and the pipe run is accessible an attempt
may be made to free the obstruction by pouring hot water over the
exposed pipe and clearing any blockage from the end of the pipe.
If this fails to remedy the problem the assistance of a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII)
should be sought.
Escape of gas
Should a gas leak or fault be suspected contact the National Gas
Emergency Service without delay. Telephone 0800 111 999
Do NOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains, wipe with a damp cloth and
finish off with a dry cloth.
DO NOT use abrasive cleaning materials.
