When you want the heating to start up, reconnect 6.

the 230/240-volt cable. The immersion heater and

the circulation pump will then start up thanks to the

battery eliminator transforming down the voltage to

12 volts.

WATER HEATER4.

The LPG boiler can be equipped with a stainless steel

water heater, with a volume of 7 litres of stored fresh

water. A maximum capacity of about 12.5 litres of hot

water at 40

C can be obtained.

When the water heater is to be used, the LPG boiler

should be started about 20 minutes in advance, and

run at maximum boiler temperature to obtain the maxi-

mum amount of hot water. If an immersion heater is

used instead of gas, the heating period is longer.

Always ush out the water heater before it is used,

particularly when it has not been used for a some time.

NB. Although the water heater is protected against

frost, fresh water in the heater must always be

drained out when there is risk of frost and the vehi-

cle is not in use.

Drain the heater like this:

Empty the fresh water tank. Open the drain cock on

the water pipe (g 6 b), and the air screw (g 6 c) on

the heater and empty out the water in the heater. If

there is no drain cock, release the hose from the nipple

on the heater instead. Allow it to stand like this until

you use the vehicle again.

If the vehicle is equipped with a pressure-controlled

pump, it must be switched on. Drain the fresh water-

tank. Open the water taps and empty the fresh water

system. Switch off the pump. Open the drain cock on

the water pipe (g 6 b), and the air screw (g 6 c) on

the heater and leave taps open. Allow it to stand like

this until the vehicle is to be used again.

MAINTENANCE OF THE HEATING 5.

SYSTEM

Check regularly the level of liquid for the heating sys-

tem in the boiler’s expansion vessel. The level should

be about 1 cm above the min. line when the boiler is

cold. The system should be lled with a 40% glycol

mixture of the same type as used in car engines (not

diesel). If the heating system is exposed to tempera-

tures lower than -25

C , the glycol content should be

raised, but must not exceed 50%. The percentageg-

lycol content should be checked before more liquid is

added. This is to prevent an excessive concentration

of glycol in the mixture. The glycol mixture should be

replaced every other year, as its properties, such as

corrosion protection, deteriorate. Never let the heating

system stand without the glycol, water liquid.

If the liquid level in the expansion vessel falls for rea-

sons other than pure evaporation, check that all joints,

the drain cock and air screws are tight. If glycol water

has leaked out, rinse with water and mop up.

Don’t forget to check the gas system regularly to en-

sure that connections and hoses are not leaking.

LPG hoses should be replaced every other year as

they dry out and crack, which may give rise to leakage.

Topping up with liquid:

Make sure that the vehicle is parked horizontally be-

fore topping up, so that no air pockets can be formed.

Check that air screws and the drain cock are closed.

Remove the upper front cover (see g 7) pull it up-

wards, the bottom outwards and then downwards.

Release the nut on the expansion vessel and lift up the

pump. Pour in the glycol mixture slowly.

NB. Alcohol must not be used as antifreeze.

Radiator cement must not be mixed in the system.

Bleeding the heating system5:1

When lling the system, air pockets may form, depend-

ing on how the system was installed. A sign that there

is air in the system is when the heat will only travel a

few metres along the radiator system from the boiler,

even though the circulation pump is running.

Bleed the system like this:

The boiler should be running and the circulation pump

off. Start by opening the air screws (the vehicle’s

instruction book will show you where they are located).

Leave them open until water comes out of nozzle. Start

the circulation pump and allow it to run for a while. Feel

the pipes and radiators in the vehicle to see it they are

getting warm.

If it is hard to get the air out of the system,

you can do as follows:

Stop the circulation pump. Jack up the vehicle at the

back or park it on a downhill slope (see g 8). Allow it

to stand a few minutes so that the air gets to the top

of the system. Open the air screw at the highest point

and leave it open until the air has come out. Then raise

the vehicle at the front and repeat the procedure in this

position (see g 9). Place the vehicle on the level and

start the circulation pump. When ow and return pipes

are almost the same temperature, the system is free of

air. When bleeding caravan systems, the easiest way

of raising and lowering the vehicle is by using the sup-

port wheel. When the system has just been lled, small

air bubbles may form in the expansion vessel. Stop the

circulation pump for a few seconds and they usually

disappear.

USEFUL FACTS ABOUT LPG6.

LPG is a petroleum product and the letters stand for

Liqueed Petroleum Gas. It is available as propane

and butane. Propane has the advantage that it is gase-

ous down to -40

C, while butane works unsatisfactorily

below 10

C. That is why propane is the most suitable

type.

When the cylinder valve is opened, the LPG liquid

turns in released as a gas. When LPG burns, carbon

dioxide (CO

) and water vapour only are emitted, just

like in the air we breathe out. In order for combustion

to be complete, a good air supply is required. LPG is

very environment friendly and does not generate soot

on complete combustion. It can be stored in cylinders
