On initial operation or when the system has been drained, refill the system with
water and flush out by turning on each hot tap until a steady flow of water is
obtained. If a water filter is fitted it should be changed at the recommended
intervals.
Check that the Gas and Electricity supplies are turned on.
OPERATION
Gas - Switch on the heater. Initially the red light will come on followed by the
green light which will stay lit as long as the burner is alight. If the gas does not
light and the red light comes back on - switch off - wait 10 seconds and switch
on again. Several attempts may initially be required for purging.
Note: When the water has reached the preset temperature no lights will show.
As the water cools or is drawn off the heater will automatically relight and the
green light will come on until the water has again reached temperature.
12VDC WIRING DIAGRAM
If at any time the light comes on indicating a fault condition, wait 3 minutes
before attempting to relight. If the fault persists, check that:
(i) The gas supply has not run out
(ii) The battery is fully charged
Electricity - The Malaga IIE has a 230v electric element which can be used
independently or in addition to the gas burner.
Note: A 12v D.C. supply must be connected at all times.
Water - This appliance must not be connected directly to the Mains Water
Supply.
Battery - The heater is designed to operate on a 12v D.C. supply. Should the
supply drop to 9 volts the heater will shut off for safety. Turn off the heater and
recharge the battery before reusing the heater.
When not in use the heater should be drained as follows:
To drain

CONNECTING THE WATER HEATER
FAULT FINDING - CHECK LIST
1 - WATER
1 - Check that the following supplies of gas, water and electricity are
available
Use half reinforced, food quality, opaque or similar pipework only. The “Hot”
and “Cold” connections are clearly marked and it is important that they are
connected correctly. If the plastic inlet connection supplied with the heater is
removed it is important that only a plastic replacement is used. The outlet
connection at the top of the tank must not be removed as this houses an
additional internal tube which provides the air space for expansion inside the
tank. The water pressure must not exceed 1.3 Bar.
DO NOT CONNECT THIS APPLIANCE TO THE A MAINS WATER SUPPLY
Drain / Pressure Relief Valve - Drill the appropriate sized hole in the floor
close to the heater. Fit a piece of hose from the drain through the floor and
seal the floor with silicon rubber or similar material.
Water Systems - The heater will operate satisfactorily on either system where
the pump is controlled by a tap, microswitches or a pressure switch.
2 - GAS
The gas connection is 8mm and suitable compression fitting is required. An
isolation tap should be fitted near to the heater and any unsupported pipework
secured. It is recommended that a gas drop hole is positioned near to the
heater. All gas connections should be carried out by a corgi registered person.

a) Manual reset button.
b) Fuse.
c) Wiring Contacts.
d) Continuity across thermostats.
3 - Replace 9 way plug and switch heater on
(i) Check for 12v at 1
(ii) Check for supply at solenoid 10 - 12V
If yes change solenoid, if no change PCB
4 - No spark at burner
3 - ELECTRICITY

cover, position into cut-out in wall and secure with screws.
Water Heater - Remove the floor
covering (e.g. carpet etc) from the area
where the eater heater will stand 450mm inward from the wall and
320mm wide. Draw a line on the floor
from the centre of the flue 600mm into
the vehicle.
Slide through the flue seals until the
stop position is reached. Make sure
both flue and air intake pass through
the lip seals.
Line up the marker on the rear of the
heater with the line on the floor and
screw the heater to the floor.
