Flue; Maintenance - Bailey ADVANCE 2019 Owner's Manual

For this reason, Alde recommends using
propane gas for all year round gas heating.
LPG cylinders contain both gas and liquid
forms. When the cylinder is filled, high pressure
transforms the gas into liquid. The liquid
reverts to gas when the valve on the cylinder
is opened.
LPG is a flammable gas. It can be a fire and
explosion hazard if stored or used incorrectly.
Store cylinders vertically and securely, to
prevent them from toppling.
Do not mount your LPG cylinder horizontally
or use liquid phase gas cylinders. Liquid–gas
explosion may result. Read the product label or
contact product manufacturer for details.
LPG is heavier than air. Should a gas leak
occur, floor vents in a motorhome should
allow the gas to escape from the vehicle. For
this reason, always ensure floor vents are
unobstructed.
The boiler compartment contains the
gas connection, floor vents and the
flue hoses. Do not place 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 (30mbar). 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.
NB: 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.
f
lue
The burning of LPG produces CO2 (carbon
dioxide), a non-toxic asphyxiant gas. Avoid
inhaling exhaust flue gas. Exhaust flue gas can
also cause possible burns and poisoning.
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 you intend on leaving the gas
heating unused for a substantial period of time
ensure the flue terminal is covered to prevent
blockage of the flue.
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.
m
aintenance
There is no manufacturer's service
requirement for the Alde 3020 Compact Boiler
itself. The installation of the boiler should be
inspected annually for gas safety.
LPG hoses should be regularly checked for
signs of damage and should be replaced, at
maximum, after 3 years of use.
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 1cm 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.
Always replace the HTF in accordance with the
antifreeze product's lifespan. If in any doubt,
replace the HTF after 2 years.
Failure to maintain the condition of HTF may
result in frost and/or corrosion damage, and is
not covered under warranty.
