Electric Heating; Domestic Hot Water - Bailey ADVANCE 2019 Owner's Manual

Listen carefully to the ignition
sequence of the boiler. You should
hear the whirr of the combustion fan,
the clunk of the gas valve and the tick-
tick of the ignition module.

When electric heating is set to 1, 2 or 3kW
relays on the PCB trip, feeding 230v supply
to the electric heating elements. These are
controlled by the same programme as the gas
heating.

The combi-type boiler automatically produces
hot water. Heat is emitted from the central
heating cylinder into the hot water cylinder.
If the hot water cylinder is empty the air is
heated but no damage can result.
In a good summer, lower the desired
temperature on the control panel to around
10°C. The central heating will not circulate
(unless the temperature drops to 10°C), but
you will still have hot water.
• The boiler must not be switched on if
there is no heat transfer fluid (HTF) in the
system.
• Always drain down the fresh water system
if there is risk of frost.
• You may continue to use the boiler with
no freshwater in the system, as required;
no damage can result.
• Always replace the HTF in accordance
with the antifreeze product's lifespan.
• If in any doubt, replace the HTF after 2
years.
• Only sterilise the fresh water system with
a product suitable for stainless steel.
• Do not place stowage in the boiler
compartment.
• Do not position awnings, tents or other
enclosures around the flue terminal.
• Do not obstruct the flue. Be careful not to
flood the flue when washing the vehicle.
• The gas heating must not be used when
refuelling the vehicle at the service
station or related facility.
Being a combi-type boiler, the Alde 3020
Compact HE has an integrated stainless steel
hot water cylinder that holds approximately
8.4 litres of fresh water.
The boiler can produce around 12 litres of
40°C warm water per 30 mins (at a cold water
temperature of 10°C). If only the electric
heating is used, this capacity is slightly
reduced.
The hot water should not be used for drinking
or cooking.
Always flush out the hot water cylinder before
use, especially when it has stood empty for
some time.
Any steriliser products should be
suitable for use with stainless steel.
Avoid steriliser products containing sodium
hyperchlorite as these will cause severe
corrosion damage to the hot water cylinder
which is not covered under warranty. Read
the product label or contact the product
manufacturer for details.
When the hot water cylinder is in continuous
use, it should be drained and refilled once a
month. This recreates the air cushion in the
hot water cylinder that absorbs pressure
surges.
If continuously using the hot water
cylinder in a hard water area, fit an
in-line scale inhibitor to minimise the
effects of limescale.
The target hot water temperature is greater
than 50°C in normal operation to prevent
the growth of Legionella. The hot water
will be heated to the maximum achievable
temperature at the time. This allows the hot
water to achieve disinfection temperatures and
increases warm water performance.
If scalding hot water temperatures are a
concern thermostatic mixing valves (TMVs) can
be fitted.
Alde recommends fitting the 3102-002
high temperature TMV.
