1.5 UNBLOCKING THE CONDENSATE DRAIN
1.6 GENERAL INFORMATION
BOILER PUMP
The boiler pump will operate briey as a self-check once every
24 hours, regardless of system demand.
MINIMUM CLEARANCES
Clearance of 165 mm above, 100 mm below, 2.5 mm
at the
sides and 450 mm at the front of the boiler casing must be
allowed for servicing.
Bottom Clearance
Bottom clearance after installation can be reduced to 5 mm.
This must be obtained with an easily removable panel, to
enable the system pressure gauge to be visible and to provide
the 100 mm clearance required for servicing.
EXPANSION
Note. If a water meter is tted into the incoming water
mains there may be a requirement for a domestic hot water
expansion vessel Kit. Contact a Gas Safe Registered
Engineer.
ESCAPE OF GAS
Should a gas leak or fault be suspected contact the National
Gas Emergency Service without delay.
Telephone 0800 111 999.
Ensure that;
- All naked ames are extinguished
- Do not operate electrical switches
- Open all windows and doors
CLEANING
For normal cleaning simply dust with a dry cloth. To remove
stubborn marks and stains, wipe with a damp cloth and nish o
with a dry cloth. DO NOT use abrasive cleaning materials.
MAINTENANCE
The frequency of servicing will depend upon the installation
condition and usage but should be carried out at least
annually by a Gas Safe Registered Engineer.

This appliance is tted with a siphonic condensate trap system
that reduces the risk of the appliance condensate from freezing.
However should the condensate pipe to this appliance freeze,
please follow these instructions:
a.
If you do not feel competent to carry out the defrosting
instructions below please call your local Gas Safe
Registered installer for assistance.
b.
If you do feel competent to carry out the following instructions
please do so with care when handling hot utensils. Do not
attempt to thaw pipework above ground level.
If this appliance develops a blockage in its condensate pipe, its
condensate will build up to a point where it will make a gurgling
noise prior to locking out, showing a “L02” fault code.
To unblock a frozen condensate pipe;
1.
Follow the routing of the plastic pipe from its exit point on
the appliance, through its route to its termination point.
Locate the frozen blockage. It is likely that the pipe is
frozen at the most exposed point external to the building or
where there is some obstruction to ow. This could be at
the open end of the pipe, at a bend or elbow, or where there
is a dip in the pipe in which condensate can collect. The
location of the blockage should be identied as closely as
possible before taking further action.
2.
Apply a hot water bottle, microwaveable heat pack or a
warm damp cloth to the frozen blockage area. Several
applications may have to be made before it fully defrosts.
Warm water can also be poured onto the pipe from a
watering can or similar. DO NOT use boiling water.
3.
Caution when using warm water as this may freeze and
cause other localised hazards.
4.
Once the blockage is removed and the condensate can ow
freely, restart the appliance. (Refer to “To Start the boiler”)
5. If the appliance fails to ignite, call your Gas Safe Registered
engineer.
Preventative solutions
During cold weather, set the central heating temperature knob
(B) to maximum (must return to original setting once cold spell
is over).
Place the heating on continuous and turn the room thermostat
down to 15ºC overnight or when unoccupied. (Return to normal
after cold spell).
