INSTALLER
12.3- 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
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.
