General Information
General Note
This boiler is designed to provide central heating from a fully
pumped open-vented or sealed water system with a fully
indirect cylinder.
Once the controls are set the boiler operates automatically.
Please read these instructions and follow them carefully for the
correct installation and economical use of your boiler.
Water Treatment
In the case of an existing installation, it is ESSENTIAL that prior
to installing the new boiler the system is thoroughly flushed. For
optimum performance after installation of a new system, the
boiler and its associated central heating system should also be
flushed. Flushing should be carried out in accordance with
BS7593: 1992 using a cleanser such as Sentinel X300 or X400,
Fernox Superfloc or Salamander corrosion guard cleaner.
For long-term corrosion protection, after flushing, an inhibitor
suitable for stainless steel exchangers should be used, refer to
the current issue of BS 5449 and BS 7593 on the use of
inhibitors in central heating systems. Examples are Sentinel
X100 Fernox or Salamander corrosion guard inhibitor.
Compartment or Cupboard Installations
If the boiler is fitted into a compartment or cupboard it does not
require ventilation openings.
Do not use the compartment or cupboard for storage.
Clearances
If fixtures are positioned close to the boiler, space must be
left as shown in diagram 2.1. Enough space must also be
left in front of the boiler to allow for servicing.
Condensate Drain
The condensate drain, see section 7.3, must not be modified or
blocked.
Pluming from flue terminal
Like all condensing boilers this appliance will produce a plume
of condensation from the flue terminal in cool weather. This is
due to the high efficiency and hence low flue gas temperature
of the boiler. It is normal and not a fault indication.
Cleaning
The boiler casing can be cleaned using a mild liquid detergent
with a damp cloth, then a dry cloth to polish.
Do not use any form of abrasive or solvent cleaner as you may
damage the paintwork.
Electrical Supply
If the mains electricity and gas are to be turned off for any
long periods during severe weather, it is recommended that
the whole system, including the boiler, should be drained to
avoid the risk of freezing. Make sure that, if fitted, the
immersion heater in the cylinder is switched off.
NOTE: If you have a sealed water system contact your
installation/servicing company as draining, refilling and
pressurising MUST be carried out by a competent person.
Manual Handling
IMPORTANT. With regards to the Manual Handling Operations,
1992 Regulations, the following lift operation exceeds the
recommended weight for a one man lift.
General recommendations when handling
Clear the route before attempting the lift.
Ensure safe lifting techniques are used – keep back straight –
bend using legs.
Keep load as close to body as possible.
Do not twist – reposition feet instead.
If 2 persons performing lift, ensure co-ordinated movements
during lift.
Avoid upper body/top heavy bending - do not lean forward/
sideways.
Recommend wear suitable cut resistant gloves with good grip
to protect against sharp edges and ensure good grip.
Always use assistance if required.
Removal of carton from delivery van
Recommend 2 person lift or 1 person with use of sack truck. If
1 person is performing lift, straddle the load, tilt and place carton
into position on truck. Recommend secure appliance onto truck
with suitable straps. Ensure safe lifting techniques are used –
keep back straight – bend using legs. Keep load as close to
body as possible. If 2 persons performing lift, ensure co-
ordinated movements during lift. Always use assistance if
required.
Carriage of carton from point of delivery to
point of installation – ground floor
Recommend 2 person lift or 1 person with use of sack truck. If
1 person is performing lift, straddle the load, tilt and place carton
into position on truck. Recommend secure appliance onto truck
with suitable straps. Ensure safe lifting techniques are used –
keep back straight – bend using legs. Keep load as close to
body as possible. If 2 persons performing lift, ensure co-
ordinated movements during lift. Clear the route before
attempting the lift. If removing boiler from truck straddle the load
and tilt forwards to facilitate secure grip. Ensure safe lifting
techniques are used – keep back straight – bend using legs. Do
not twist – reposition feet instead. Take care to avoid trip
hazards, slippery or wet surfaces and when climbing steps and
stairs. Always use assistance if required.
