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 a fault code will show in the
display.
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’and a fault code will show in the display.
To RESET the heater press the ON-OFF button to switch off then depress the
ON-OFF button to restart. 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’ and a fault code will show in the display. It will be impossible to re-start the heater without fixing the problem. You should call your installer or phone MORCO on 01482 325456.

4.- MAINTENANCE
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 venturi 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.

5.- FROST PROTECTION
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.

other sources of natural air infiltration, such as other flues etc, with the exception
of doors, but not the opening windows thereof.
The minimum acceptable dimensions from the terminal to obstructions and
ventilation openings is as follows:
Directly below an opening fixed vent or window etc ...............300mm
Ajacent to an opening fixed vent or window etc .....................300mm
Below gutters ........................................................................75mm
From a vertical drain pipe ......................................................75mm
From an internal or external corner .......................................300mm
Where the terminal is fitted in a position to which children, the elderly, or
disabled people have access (less than 1.5m above steps, decking or ground), a
suitable terminal guard should be fitted.
In certain weather conditions the terminal may emit a plume of steam.
12.4- MINIMUM CLEARANCES
Minimum clearances of 5mm to the front and sides of the heater must be
observed. However full access from the front in the form of an opening door, must
be given to allow access to the controls and for servicing.
200mm above the top of the heater case is required for the flue assembly.
150mm is required below the heater to allow easy access to the gas isolation
cock.
12.5- VENTILATION REQUIREMENTS
The Morco F-11E L is a room sealed appliance and needs no purpose provided
combustion air ventilation.
12.6- ELECTRICITY SUPPLY
A 3 amp fused three pin plug and unswitched shuttered socket outlet (both
complying with BS 1363) or a 3 amp fused double pole isolator with a contact
separation of 3mm in all poles supplying only the heater should be used.
THIS APPLIANCE MUST BE EARTHED
12.7- GAS SUPPLY
Ensure the heater is set for the gas supply intended.
Ensure the regulator is of sufficient capacity to carry the maximum heater input
plus the demand for any other appliance in the system.

INSTALLER
Before commissioning, ensure that the whole gas installation is purged and tested
for soundness.
IMPORTANT: To prevent damage to the gas valve soundness testing of the system
must only be done with the isolation cock on the heater in the closed position. Any
over pressure such as is allowable to carry out a pipe soundness test could
possibly damage the heater.
