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
