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 prosecu-

tion. 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 oper-

ate the appliance.

1.1 INTRODUCTION

The Sime “FORMAT C” family is a fully automatic, wall mount-

ed, room sealed, fan assisted range of combination boilers.

When operating in winter mode, the appliance provides cen-

tral 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 modu-

lating gas valve (within its pre-set 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 ther-

mostat 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 appli-

ance 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.

Check that the burner has lit by looking through the view-

ing window (F). 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 (D) to maxi-

mum (fully clockwise).

– Turn the selector switch summer/winter to the WINTER

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

DHW

ISOLATION VALVE

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 auto-

matically 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 selector switch summer/winter (C) to OFF posi-

tion. When required restore the switch to the SUMMER

or WINTER position and turn on the D.H.W. isolation valve.

–For longer periods:

Set the selector switch summer/winter (C) to OFF posi-

tion and isolate the gas service cock.

When required restore the switch to the WINTER or

SUMMER position and turn on the D.H.W. isolation valve.

Do not isolate the mains electricity or gas supply if frost

protection is required.

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 registerd person (Gas Safe Register).

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 and release it imme-

diately, then turn it back to the previous position (see fig. 2).

If the cut-out condition is repeated, turn off the electrical sup-

ply and consult your installer or service engineer.

1.6.2 Temperature/pressure gauge

The gauge (A fig. 1) on the facia panel indicates the approxi-

mate 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 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 and release it immediately, 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 con-

nected to the terminal in the plug which is marked with the

letter E or by the earth symbol - or coloured green and yel-

low; 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 ter-

minal marked with the letter L or coloured red.

1.6.5 Ventilation

If the appliance is installed in a cabinet, the latter MUST NOT

be used for storage purposes.
