THE GAS SAFETY (INSTALLATION AND USE) REGULATIONS
1996. It is the law that all gas appliances are installed by a
registered person, in accordance with the above regulations.
Failure to install appliances correctly could lead to prosecution. It is in your own interest, and that of safety, to ensure
that the law is complied with.
It is essential that the appliance is correctly earthed. An
electricity supply of 240 V - 50 Hz fused at 3 A is required.
Read these instructions carefully before attempting to operate the appliance.
1.1 INTRODUCTION
The Sime “ECOMFORT” is a fully automatic, wall mounted,
room sealed, fan assisted combination boiler. When operating
in winter mode, the appliance provides central heating as
required and produces instantaneous hot water upon
demand.
When operating in summer mode, the central heating is not
operational however the appliance continues to supply hot
water whenever it is required. The heat output is automatically controlled by the fully modulating gas valve (within its preset limits), and there are user adjustable potentiometers to
control the temperature of both central heating and domestic hot water. A temperature/pressure gauge is fitted and an
overheat thermostat is incorporated to protect against fault
conditions.
1.2 APPLIANCE OPERATION
A demand of hot water will be sensed by the appliance
detecting water flow (providing that the flow rate is above 2
l/m - 0.5 gal/min).
The fan will start and the burner will light at full output. If
the draw off rate is near the maximum design flow rate
the appliance will run continuously at full output until a tap
is either turned off or the flow rate is reduced in which
case the heat output will reduce accordingly to maintain a
steady temperature.
Hot water is made available almost immediately at the appliance outlet, but the final temperature and time taken for the
hot water to reach a tap depends upon the potentiometer
setting, the rate at which water is drawn off, and the length
of the pipe between the boiler and the tap.
When the tap is turned off, the appliance will revert to C.H.
mode (if set on winter position) otherwise the burner will be
extinguished pending the next demand for hot water.
1.3 OPERATING INSTRUCTIONS
1.3.1 To light the appliance (see fig. 1)
– Check that the electricity supply is off and that the D.H.W.
isolation valve is in the open position (lever vertical). Check
that the gas supply is on.
– Turn the selector switch summer/winter (C) to SUMMER
(water only) position “ ”.
– Switch on the electricity supply and full open any D.H.W.
tap. The burner will light.
If the burner fails to light, turn the selector switch summer/winter to “ “ position and release it immediately;
then turn it to the SUMMER position: the burner should
now light. Turn off the tap.
– Check that the room thermostat and time clock are call-
ing for heat. Turn the heating potentiometer (E) to maximum (fully clockwise).
– Turn the selector switch summer/winter to the WINTER
position “❄" and the burner will light to serve the heating load.
Set the required temperature for the C.H. and D.H.W. by

rotating the potentiometers (D - E) clockwise to increase
or anticlockwise to decrease the temperature.
NOTE: when operating in winter mode, priority is automatically given to providing hot water when the demand
arises.
1.3.2 To turn off the appliance (see fig. 1)
– For short periods:
Set the selector switch (C) to the OFF position and urn off
the DHW Isolation valve. When required, restore turn the
selector switch to either the SUMMER or WINTER position and turn on the DHW Isolation valve.
– For longer periods:
Set the selector switch (C) to the OFF position, turn off
the DHW Isolation valve, turn off the gas isolation cock.
When required, manually rotate the pump, open the gas
isolation cock, turn on the DHW Isolation valve and turn
the selector switch to either the SUMMER or WINTER
position.
NOTE: If frost protection is required-turn the selector
switch to the summer position, do no
t isolate the gas
supply, turn off the DHW Isolation valve.
1.4 MINIMUM CLEARANCES
The following MINIMUM CLEARANCES must be available for
servicing the appliance:
1.5 ROUTINE SERVICING
To ensure continued efficient operation of the appliance, it is
recommended that it is checked and serviced as necessary at
regular intervals. The frequency of servicing will depend upon
the particular installation conditions and usage but in general
once a year should be adequate. It is the law that any service
work must be carried out by a registerd person (C.O.R.G.I.).
1.6 GENERAL INFORMATION
1.6.1 Fault finding indicators (LEDS)
The appliance is fitted with a safety cut-out thermostat. In
the event of overheating this will interrupt the power supply
and prevent the appliance from functioning. If this occurs,
allow the appliance to cool, turn the selector switch summer/winter to “ “ position, then turn it back to the previous
position (see fig. 2). If the cut-out condition is repeated, turn
off the electrical supply and consult your installer or service
engineer.

1.6.2 Temperature/pressure gauge
The gauge (A fig. 1) on the facia panel indicates the approximate system pressure. The normal operating pressure is
between 1 and 1.5 bar. If the normal running pressure is
seen to decrease over a period of time there is a water leak
and you should consult your installer or service engineer.
1.6.3 Electrical supply
The mains plug used must be a 3 pin type to BS1363, and
fused at 3 A. THIS APPLIANCE MUST BE EARTHED.
NOTE:
an interruption in the electricity supply whilst the burner
is alight may cause the overheat thermostat to operate. If
this is suspected, turn the rotary switch to “ “ position,
then turn it back to the previous position.
TO CONNECT A PLUG
As the colour of wires in the mains lead of this appliance may
not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:
the wire which is coloured green and yellow must be connected to the terminal in the plug which is marked with the
letter E or by the earth symbol - or coloured green and yellow; the wire which is coloured blue must be connected to
the terminal marked with the letter N or coloured black; the
wire which is coloured brown must be connected to the terminal marked with the letter L or coloured red.
1.6.4 Ventilation
If the appliance is installed in a cabinet, the latter MUST NOT
be used for storage purposes. Any ventilation provided for
the appliance during installation MUST NOT be blocked and a
periodic check must be made to ensure that the vents are
free from obstructions.
1.6.5 Cleaning
Use only a damp cloth and mild detergent to clean the appliance outer casing. DO NOT use abrasive cleaners.
1.7 SAFETY
It is essential that the instructions in this booklet are strictly followed for the safe and economical operation of this
appliance. The appliance functions as a fan assisted balanced flue unit.
The flue terminal MUST NOT BE OBSTRUCTED under any circumstances. If damaged, turn off the appliance and consult
the installer, service engineer, or gas supplier. If it is known or
suspected that a fault exists on the appliance it MUST NOT
be used until the fault has been rectified by a competent person.
WARNING: IF A GAS LEAK IS SUSPECTED OR EXISTS,
TURN OFF THE GAS SUPPLY TO THE APPLIANCE AT THE
GAS SERVICE COCK. DO NOT OPERATE ANY ELECTRICAL
SWITCHES. DO NOT OPERATE ANY ELECTRICAL APPLIANCE. OPEN ALL WINDOWS AND DOORS. DO NOT
SMOKE. EXTINGUISH ALL NAKED LIGHTS. CONTACT THE
GAS SUPPLIER IMMEDIATELY.
