IMPORTANT:
The installer must explain to the user how the water heater functions,
including its safety devices and the instructions for use.
To start up the water heater, it must firstly be connected to the mains using the
plug for this purpose.
• Ensure gas and water supplies are connected.
• Ensure the electricity supply is switched on.
Obtaining hot water
To start up the heater depress the ON-OFF button (3). The heater will then be
ready to function automatically when any of the hot water taps are turned on.
The orange LED (5) will come on while the heater is working.

Selecting the required power
Turn the power selector (1) to obtain the desired power.
MAX position indicates 100% power.
MIN position indicates 50% power.
Selecting the hot water temperature
Turn the water temperature dial (2) to obtain the desired
temperature.
MAX position indicates the maximum temperature (minimum flow).
MIN position indicates the minimum temperature (maximum flow).
IMPORTANT: This heater is not thermostatic.
Note: It is advisable to adjust both the power and the water temperature to the
minimum value necessary to cover your requirements. This will save energy and
prolong the life of the appliance, reducing scale deposits on the heat exchanger.
Switching off the water heater
When the hot water tap is turned off, the heater will stop automatically.
To switch off the heater completely, press the ON-OFF button (3).
IMPORTANT: When the heater is switched on for the first time, or if it has
not been used for a certain time, or when a new gas bottle is installed, the
appliance may fail to ignite due to the presence of air in the gas pipes. If
this happens, the heater will ‘LOCK OUT’ and the red LED (4) will be
displayed.
Occasionally, the heater may fail to ignite due to excessively windy
conditions or other adverse atmospheric conditions, causing ‘LOCKOUT’.
Insufficient gas pressure (faulty regulator) or fluctuations in voltage may
also cause ‘LOCKOUT’.
To RESET the heater press the ON-OFF button to switch off then depress the
ON-OFF button to restart. The red LED should now be off and the heater
should ignite when the hot tap is opened.
If the heater locks out persistently, call your installer or MORCO on 01482
325456 for details of your nearest service agent.
Combustion product removal control device (Air pressure switch)
IMPORTANT: The user must not interfere in any way with this device. Under no cir-
cumstances may it be disconnected, modified or replaced by a different part.
If the flue becomes blocked for any reason, or it is contaminated the heater
will ‘LOCKOUT’. It will be impossible to re-start the heater without fixing the
problem. You should call your installer or phone MORCO on 01482 325456.

Note: before carrying out any maintenance or repair operations, the heater MUST
be disconnected from the mains electric, and the gas and water supply.
MORCO recommends yearly inspection of the heater by a qualified and
competent service engineer.
The following inspections should be carried out:
• Check that the electrical installation is in good condition
• Check for soundness of the gas and water installations.
• Check for blockages and contamination of the flue assembly, especially
spiders webs and egg-sacks which can find their way along the flue and into
the venturii causing ‘LOCKOUT’.
• Check for correct gas pressure.
• Check that the burner and heat exchanger are free of soot and other
contamination.
Cleaning the burner
Remove the burner and clean the bars with a soft brush or compressed air. Do
not use chemical products.
Remove the ignition and ionisation spark electrodes and clean the ends.
The electrode unit should be replaced every three years.
Cleaning the heat exchanger
Clean the heat exchanger with hot water. If it is particularly dirty, leave it to soak
in hot soapy water.
Replace the heat exchanger seals when it is refitted.
Cleaning the cover
Clean the cover with a damp cloth. Do not use aggressive detergents.
Scale prevention
If the appliance is installed in a hard water area and if the following appear over time:
• a reduction in the hot water temperature, or
• a reduction in the hot water flow
this means that scale deposits have formed in the heat exchanger.
To reduce this effect, we recommend obtaining the desired working temperature
by using the gas power control and the temperature selector, rather than by
mixing cold water at the tap.
4.- MAINTENANCE
During freezing cold weather, the appliance must be drained down, leaving the
appliance undrained during freezing conditions, will result in the appliance being
frost damaged.
It must be drained down in the following way:
• Turn off the gas and electrical supply.
• Turn off the mains water inlet stopcock.
• Turn temperature control knob fully anticlockwise to minimum setting.
• Turn on all hot and cold water taps.
• Open all hot and cold drain cocks on the installation. Please refer to your
caravan owner’s handbook for the location of all drain cocks.
• Disconnect the mains water inlet stopcock from the caravan pipework, this will
stop water refilling the pipework, if the stopcock fails due to frost damage.
• Protect drain cocks and any open ended pipe from insects or debris.
To turn the water on again, close all drain cocks, reconnect and open the mains
water inlet stopcock and turn off each hot and cold water taps as the water runs
clear.
We strongly recommend a qualified & competent service engineer is employed
to do the drain down service.

This is a room-sealed fan flued water heater with electronic direct ignition with
ionisation safety. It is mains powered and has a mechanically modulating gas
valve responding to water flow rate. Its room sealed combustion chamber,
equipped with a fan for the intake of air from the outside and the removal of
combustion products to the outside, enables it to function totally independently of
the room in which it is installed. For this reason it is ideally suited for use in leisure
accommodation vehicles such as caravan holiday homes, motor homes, and
specialised vehicles. It is also suitable for boats.
