Control of substances hazardous to health

Under Section 6 of The Health and Safety at Work Act 1974,
we are required to provide information on substances haz-
ardous to health. The adhesives and sealants used in this
appliance are cured and give no known hazard in this state.
1.5.5

Insulation pads

These can cause irritation to skin, eyes and the respirato-
ry tract. If you have a history of skin complaint you may
be susceptible to irritation. High dust levels are usual
only if the material is broken. Normal handling should not
cause discomfort, but follow normal good hygiene and
wash your hands before eating, drinking or going to the
lavatory. If you do suffer irritation to the eyes or severe
irritation to the skin seek medical attention.

Spare parts

Only original Vaillant spare parts may be used.

loading the appliance until it is fully mounted on the wall in
its final installed location must exercise full duty of care for
themselves and others with regard to safe lifting and han-
dling of this appliance. Operatives should employ assistance
whilst lifting the appliance or components. In certain situa-
tions it may be required to use a mechanical handling aid.
Take care to avoid trip hazards, slippery or wet surfaces.

With regards to the Manual Handling Opera-
tions, 1992 Regulations, the following lift oper-
ation exceeds the recommended weight for a

Clearances

If fixtures are positioned close to the boiler, space must
be left as shown in fig 4.1. Enough space must also be
left in front of the boiler to allow for servicing.

1.5.10 Sheet metal parts

This boiler contains metal parts (components) and care
should be taken when handling and cleaning, with par-
ticular regard to edges.
1.5.11

Sealed components

Under no circumstances must the User interfere with any
sealed component as this could result in a potentially
dangerous situation arising.
Danger!
e
This boiler must be earthed.

1.5.12 Electrical supply failure

The boiler will not work without an electrical supply. Normal
operation of the boiler should resume when the electrical
supply is restored. Reset any external controls to resume
normal operation of the central heating. If the boiler does
not resume normal operation. (The burner fails to ignite
after five attempts). The overheat thermostat may have
operated. Automatic ignition can only take place after you
manually reset the fault, refer to section 5.1.3. to reset.

1.5.13 Protection against freezing

The boiler has a built in frost protection programme as long
as the electricity and gas are left switched on. This device
operates the burner and system pump when the tempera-
ture inside the boiler falls to 3°C. Any other exposed areas
of the system should be protected by a separate frost ther-
mostat. If the mains electricity and gas are to be turned off
for any long periods during severe weather, it is recom-
mended 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.
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 approved at
the time by the Health and Safety Executive.
As a safety feature the boiler will stop working if the
condensate drain becomes blocked. During freezing
conditions this may be due to the forming of ice in the
condense drain external to the house. Release an ice
blockage by the use of warm cloths on the pipe. The
boiler should then restart. Contact your installation/
servicing company if the fault persists.
