HEATING WITH LP GAS

ABOUT LP GAS
LP Gas is a petroleum product, formally known as "liquid
petroleum gas." It is mainly made up of propane and
butane gas. The advantage of propane is that it remains
gaseous at temperatures as low as -40°F (-40°C).
For this reason, propane is used in colder climates.
LP Gas cylinders contain LP Gas in both liquid and
gaseous forms. When the cylinders are filled, the
pressure turns the gas into liquid. When the gas cylinder
valve is opened, the liquid becomes a gas again.
DANGER
FIRE/EXPLOSION HAZARD
FARA
The risk involved in using LP Gas is that any leak-
ing gas may ignite and explode. Since LP Gas
DANGER
is heavier than air, leaking gas will collect at the
GEFAHR
lowest point in the area where the leak occurs. To
make it easier to detect gas leaks, a substance with
FARE
a distinctly rank smell has been added to the gas.
VAARA
– For your safety install a gas alarm.
PELIGRO
DANGER
PERICOLO
SUFFOCATION HAZARD
LPG contains no toxic substances, but breathing in
FARA
GEVAAR
concentrated gas may cause suffocation due to lack
DANGER
of oxygen. Incomplete combustion of LP Gas can
also produce carbon monoxide (CO) gas, which is a GEFAHR
suffocation hazard.
FARE
– For your safety, install and use a CO detector.

HIGH EXHAUST TEMPERATURES
FARA
The exhaust temperatures from the LP Gas burner GEVAAR
can be up to 392°F (200°C).
DANGER
Use the thermostat to control the heat when using
GEFAHR
LP gas. Refer to the Control Panel instructions (Page 12).
FARE
When LP Gas operation is selected on the Control Panel,
the gas burner in the boiler and the pump for circulating VAARA
the glycol heating fluid start automatically whenever heat
PELIGRO
is called for by the thermostat. The burner keeps burn-
ing and the pump keeps circulating until the thermostat PERICOLO
reaches the set temperature. Should the boiler go out for
GEVAAR
any reason, a sensor will be activated and the boiler will
attempt to automatically restart (in about 10 seconds).
SNOWY CONDITIONS
DANGER
SUFFOCATION HAZARD
FARA
In order to burn properly and safely, the LP Gas
boiler must have adequate air intake. Inadequate
DANGER
air intake may cause the build-up of CO gas, which
GEFAHR
is a suffocation hazard. The inlet air to the LP Gas
boiler enters through the flue, which is usually
FARE
installed on the side of the RV near the heater. While
VAARA
camping during the winter, make sure that the flue
is kept clear of snow and ice.
PELIGRO
Do not start the LP Gas boiler until the flue is com-
PERICOLO
pletely free of snow and/or ice.

HEATING WITH ELECTRICITY

ELECTRICAL HEATING
All Alde Compact 3010 boilers are fitted with two 120 V
heating elements with a maximum output of 950 W each.
These heating elements require a 16-amp breaker.
NOTICE
Ensure that correct electrical service is available
before using the electric boiler.
Use the thermostat to control the heat when using
electricity. Refer to the Control Panel instructions
(page 12). When electrical operation is selected on the
Control Panel, the electrical heating elements are used to
heat the boiler. The heating elements and the circulating
pump are controlled by the thermostat in the same way
as the gas boiler.

THE PRINCIPLE OF CONVECTION

AIR CIRCULATION
Both LP Gas and electric heating use hot glycol fluid to
heat the space in the RV. In order to achieve the best
possible result from the principle of convected heat, it is
important to allow air to circulate freely under bunks and
behind backrests and wall-mounted cabinets
(See Figure 4). If the vehicle has a fitted carpet, ensure
that the carpet does not obstruct the air supply to the
convectors. It is just as important that cushions or
blankets do not interrupt the flow of air behind backrests
and wall cabinets.
NOTICE
Obstruction of the air supply to convectors cause
poor or no heating of the vehicle.
DANGER
CARBON MONOXIDE POISONING
Check supply and exhaust air intake, the vehicle
FARA
is often equipped with supply and exhaust air
DANGER
valves (refer to vehicle instructions) that must not
GEFAHR
be blocked as this will impair the efficiency of the
heating system and air quality, which can lead to
FARE
carbon monoxide poisoning.
