GAS SAFETY (INSTALLATION AND USE) REGULATIONS

1984. It is the law that all gas appliances are installed by a
competent 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 “FRIENDLY” is a wall mounted, fan assisted
balanced flue combination boiler. When operating in winter
mode, the appliance provides central heating as required
and produces instantaneous hot water upon demand up to
a maximum output of 24.0 kW (82,000 Btu/h). 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 thermostats to con­trol the temperature of both central heating and domestic
hot water. 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

2.8 l/m - 0.62 gal/min). The fan will start and the main 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 thermo­stat 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 (J) is in the open position. Check
that the gas supply is on.

– Turn the Summer/Winter switch (B) to SUMMER (water

only) position “ ”.

–

For “FRIENDLY” model switch on the electricity supply.
Fully depress the gas valve control knob (H) and hold in.
After approximately 15 secs. a spark will light the pilot.
After a further 20 secs. release the button and the pilot
should remain alight (check through the viewing win­dow). Fully open any D.H.W. tap and the burner will
light. Turn off the tap.

– For “FRIENDLY E” model switch on the electricity supply

and full open any D.H.W. tap. The burner will light.
Check that the burner has lit by looking through the
viewing window (G). If the burner fails to light, press the
overheat thermostat reset button (I) once and the bur­ner should now light. Turn off the tap.

– Check that the room thermostat (if fitted) is calling for

heat and turn the clock overriding switch (A) to the ON
position “●”. Turn the heating thermostat (C) to maxi­mum (fully clockwise).

– Turn the Summer/Winter switch to the WINTER position

“❄" and the burner will light to serve the heating load.

– Set the Summer/Winter switch (and the room thermo-

stat if fitted), to the desired position and set the requi­red temperature for the C.H. and D.H.W. by rotating the
thermostats (C - D) 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 the appliance off (see fig. 1)

– For short periods:

Set the Summer/Winter switch (B) to SUMMER position
“ ”. When required - restore the switch to the WIN­TER position “❄”.

– For longer periods:

Set the Summer/Winter switch (B) to SUMMER position
“ ”. For “FRIENDLY” model turn the gas control knob
clockwise to extinguish the pilot. Isolate the gas service

cock (K).

When required - restore the switch to the WIN-

TER position “❄" and turn on the gas service cock.
For “FRIENDLY E” model follow the procedure for ligh-
ting the pilot.

NOTE: when gas and electrical supplies must be
turned off, the entire system should be drained,
including the domestic water system.

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 competent person
such as British Gas or other Corgi registered personnel.

1.6 GENERAL INFORMATION

1.6.1 Appliance overheat thermostat

The appliance is fitted with a safety cut-out thermostat. In
the event of overheating this will operate and interrupt the
pilot thus preventing the appliance functioning. If this
occurs allow the appliance to cool and then follow the pro­cedure for lighting the pilot.
For “FRIENDLY E” model before lighting the boiler press
the overheat reset button (I).
If the cut-out condition is repeated, turn off the electrical
supply and consult your installer or service engineer.

1.6.2 Pressure gauge

The gauge (F fig. 1) on the facia panel indicates the approxi­mate system pressure. 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 appliance MUST be connected to the supply via a
fused, double pole switch, having 3 mm (1/8 in) contact
separation in both poles, serving only the boiler and system
controls. The fuse rating should be as per the original
instructions. A competent, qualified electrician MUST be
consulted.

NOTE: an interruption in the electricity supply whilst
the burner is alight may cause the overheat thermo­stat to operate. If this is suspected, depress the reset
button (I fig. 1) once (for “FRIENDLY” model).

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 Setting the heating programmer

To set the heating timeswitch proceed as follows:
– the heating timeswitch is surrounded by 96 teeth,

when pushed in, each one switches on the boiler for 15
minutes;

– push down the teeth corresponding to the HEATING ON

requirements;

–

set the clock to the correct time by rotating the dial
clockwise until the arrow corresponds to the current time;

1.6.5 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.

1.6.6 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
Local Gas Region. 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 LOCAL GAS REGION IMMEDIATELY.
