DESCRIPTION OF THE APPLIANCE
The Morco EUP11RS is a room sealed, fan flued instantaneous gas water heater. This means its operation is independent of the room it
is installed in as the air for combustion is obtained from outside the home and the flue gases are expelled outside the home. It is
therefore suitable for use in Leisure Accommodation Vehicles (LAVs) such as boats and caravan holiday homes. We do not recommend
the use of this appliance in motorhomes. Ignition of the flame is electronic and will take place automatically when a hot tap is opened.
The appliance does not store hot water.
The display on the appliance may exhibit “AL” if it does not work correctly. The appliance has the ability to self-diagnose certain faults.
Please refer to the fault code table on page 15 before contacting a Gas Safe Engineer. Some of the faults are a temporary and some
are permanent.
The packaging of the water heater includes:
•Wall mounting bracket with screws and plugs
•2 flue restrictor rings - 1 x 43mm and 1 x 45mm

Precautions
The appliance must be installed on a suitable wall that allows for the
installation of a horizontal or vertical flue.
- To allow maintenance operations, leave the minimum distances
shown (Fig. 8) around the appliance.
Location
- If the appliance is positioned in areas exposed to the risk of frost,
the water heater must be disconnected and drained of water – see
Winterisation section.
Fig. 8 - Minimum required distances
Connection of the water heater to the water, gas and flue
gas exhaust systems and the room where the heater is to
be installed must comply with the rules and regulations in
force, see above.
Following installation of the water heater, check the tight-
ness of all the gas and water connections.
Installation of this appliance should be carried out by a Gas
Safe Engineer in the UK or other qualified personnel.
Verify if the available gas type and pressure corresponds
to that indicated on the appliance data plate.
Install an isolation valve on the gas supply, upstream of the
appliance, in a visible and accessible position and as close
as possible to the appliance.
Check the water hardness (200 ppm maximum allowable
total hardness). If it exceeds 200 ppm a scale reducing
device must be fitted upstream from the appliance for
softening water. Hard water will slowly reduce the
operational efficiency and reliability of the water heater.

Support bracket
Having established the position of the appliance fix the wall
mounting bracket in the appropriate position.
The most common installation is shown below in Figure 9.
Fig. 9 - Support bracket and horizontal flue rear exit location
Electrical connection
Gas connection
The diameter of the gas pipes should be suitably sized to
accommodate for all of the gas appliances in the home.
A gas isolation valve should be fitted to the gas inlet of the
appliance or an inline isolation valve fitted close to the appliance on
the supply pipe.
For initial start-up of the appliance, the following checks must be
carried out by a Gas Safe Engineer.
1. Check the gas inlet pressure is 37mbar (or relevant pressure for
the country that the appliance is being commissioned in) with all
other gas appliances in the Holiday Home working at maximum.
2. Turn on the water supply to the water heater and check for leaks.
3. Turn the tap on full and check the flow and temperature according
to the Technical Data on page 14. You may have to do this by
disconnecting the hot water feed to the plumbing pipework as
there may flow regulators fitted to certain taps.
4. Check burner pressure as in Technical Data on page 14.
5. Adjust control knob water temperature and check temperature of
water changes at the tap.
6. Check with a calibrated Flue Gas Analyser that your ratio is
< 0,025 % (or 250 ppm) CO Dry Air Free
Do not use the gas pipes as electrical appliance earthing devices.
Water connection
Power the appliance via a double pole switch.
N.B. no responsibility is accepted for damage to persons, animals
or property caused by failure to earth the appliance and the creation
of an electrical installation that does not comply with current
standards.
For the main power supply of the appliance from the mains, the use
of adapters, multiple sockets and/or extension cords is not permitted.
The use of any component that uses electricity involves the
observance of a number of fundamental rules such as:
- Do not touch the appliance with wet parts of the body and/or bare
feet
- Do not pull the electrical cables
- Do not leave the appliance exposed to atmospheric agents
(rain, sun, etc.)
- Do not allow the appliance to be used by children or

FLUE TERMINAL POSITION
The heater must be installed so that the terminal is exposed to the external air. It is important that the position of the terminal allows
free passage of air across it at all times. It is essential to ensure that the products of combustion discharging from the terminal cannot
re-enter the building or vehicle, through ventilators, windows, or 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
Adjacent 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.
Flue - Exhaust Gas and Air Inlet
The appliance can be used with a horizontal or vertical flue system. The respective part codes are RSF503 and RSF545. The Flues
feature concentric tubes, the inner 60mm Ø tube is for the flue exhaust gas and the outer 100mm Ø tube is for the air inlet.
Current flue standards should be adhered to and the flues fitted must be the above supplied by Morco Products as these are CE certified
for use with the appliance.
TYPE C: Horizontal coaxial exhausts
In this configuration, air intake and combustion product exhaust
is outside the home through concentric pipes.
Coaxial exhausts can be faced in the direction most appropriate
to room needs, meeting the methods and lengths indicated
in the following table.
The reference quotas for where to trace wall hole for the
support bracket are provided in figure 10.
TYPE C: Vertical coaxial exhausts
Use the vertical exhaust manifold and, if necessary, the
relevant extensions, observing the maximum admitted lengths
as indicated in the table.

WINTERISATION
Winterisation of Holiday Homes That Have a Water Heater
Fresh water freezes at 0°C and expands by 9% with a significant force that will destroy:
•Pipe work
•Water heater components
•Taps, and shower valves
DRAIN DOWN
If you leave fresh water in your caravan system over the winter you will run the risk of damage. This can only be avoided by removing the
fresh water from the system – we call this a “drain down”. You may wish to drain down the fresh water system yourself using the
procedure in the next section but we STRONGLY RECOMMEND that you have this carried out by an experienced engineer as many
caravan systems can only be completely drained by blowing the water out and this requires specialist equipment. View the £50-£60
charge for a drain down as a mini insurance policy and always ask the engineer if he has equipment to blow the water out. The two most
common parts to be damaged by frost are the shower valve and the water control assembly in a water heater and the costs to replace
these are around £100 each.
Drain Down Procedure – without specialist equipment
•Turn off the fresh water supply stop cock outside the Holiday Home
•Disconnect the fresh water feed outside the home if possible as this protects from flooding due to stop cock failure
•Open all hot and cold taps and shower valves and place the shower head in the tray
•Use the Holiday Home Owner’s Handbook to locate all the fresh water drain cocks under the van – some of these may not be
obvious
•Open these drain cocks
This procedure does not guarantee that all the fresh water will leave the system. Most modern homes have double check valves in the
TMV2 shower mixers and these trap fresh water and stop the flow of water around the system once the drain cocks and taps are open. It
may appear that all the water has left the system, but beware! This pitfall can be avoided by removing the shower mixer valve/valves
from the system after the cold water supply has been switched off and the drain cocks opened. Many manufacturers provide access
panels and these may make the removal of shower mixers easier. Removal of some shower mixers requires the use of special tools.
In addition, pipe work layouts can cause air locks leaving water inside vulnerable components such as the water heater or shower mixer.
Re-commissioning the home is a reverse of the above procedure.
This drain down procedure may work but the only way to be sure is to blow the water out using compressed air at 3 bar maximum
pressure.

WARRANTY
