Flue; Maintenance - Bailey Approach Autograph Series Owner's Manual

floor vents in a caravan or motorhome should
allow the gas to escape from the vehicle. For
this reason, always ensure floor vents are
unobstructed.
WARNING: The boiler compartment
contains the gas connection, floor
vents and the flue hoses. Do not
obstruct by placing stowage in the
boiler compartment.
In the event of a gas leak, or if you smell gas:
• Extinguish all naked flames.
• Open all doors and windows.
• Close all gas valves, including the valve on
the cylinder.
• Do not smoke.
• Do not operate any electrical appliances or
switches.
• Arrange for immediate inspection of the
gas system by a competent person in
accordance with current local regulations.
LPG from the cylinder is reduced in pressure by
a regulator, and is supplied to the boiler at low
pressure (30 mbar). Never use an unregulated
high pressure supply.
Where oil and dirt in the gas supply are a
concern, gas filters should be fitted to prevent
blockage of the boiler gas valve.
If the gas locker has an ingrained smell, Alde
Leak Spray can be used to quickly test gas pipes
and connections.
NOTE: Gas heating must not be used
while driving your vehicle unless a
safety shut-off device is fitted to the
gas system. Current local regulations
must be adhered to.

Flue

The burning of LPG produces CO
dioxide), a non-toxic, asphyxiant gas.
Exhaust flue gas can cause possible burns and
poisoning. Avoid inhaling exhaust flue gas.
WARNING: Do not position awnings,
tents or other enclosures around the
flue terminal.
Air supply is essential for clean combustion.
The air intake is located in the flue terminal. For
best performance, the flue terminal should be
well vented. If leaving the gas heating unused
for a period, ensure the flue terminal is covered
to prevent pest animals nesting in the flue.

Maintenance

There is no manufacturer's service requirement
for the Alde 3020 Compact HE boiler itself.
Current local regulations must be adhered
to. The installation of the boiler should be
inspected annually for gas safety.
Annually check the flue for corrosion or damage;
replace if there are any signs of damage.
LPG hoses should be regularly checked for signs
of damage or wear that might result in failure.
Bleed air from the system when newly filled,
when the vehicle has been standing unused for
a period, and before departing on holiday.
The fluid level in the expansion tank should
be about 1 cm above the MIN mark when cool.
The heat transfer fluid (HTF) should be topped
up if below this level, to prevent a break in
circulation. Only top up with compatible HTF.

Failure to maintain the condition of HTF may
result in frost and/or corrosion damage, and is
not covered under warranty.
WARNING: Do not obstruct the flue.
Be careful not to flood the flue when
washing the vehicle.
Air is sucked into the combustion
chamber via the air intake. The gas
heating must NOT be used when
refuelling the vehicle at the service
station or other fuelling facility.
NOTE: Never leave the system empty
of HTF.
WARNING: Always replace the HTF in
accordance with the antifreeze
product's lifespan. If in any doubt,
replace the HTF after 2 years.
