Mandatory warning for CE countries
WARNING, these appliances were designed, approved and inspected to meet the requirements of the English
market. The identification plate located on the inside of the appliance certifies the origin where the product was
manufactured and the country for which it is intended.
If you see any exception to this rule, please contact your nearest stockist.
Thank you in advance for your assistance.
Note: The boiler serial number is marked on the data label attached to the fascia behind
the front panel. Refer to the ‘Introduction’ section for a description of the basic functions
of the boiler. The ‘User’ section describes how to safely operate the boiler.

USERS INSTRUCTIONS
The Protherm 100 e is a wall mounted combination boiler providing central heating and instantaneous domestic
hot water.
These instructions should be carefully followed for the safe and economical use of your boiler.
Gas leak or fault
If a gas leak or fault exists or is suspected, turn the boiler and gas supply off and consult the local gas company
or your Installer/Service provider.
In case of power supply failure
The boiler no longer operates.
As soon as power supply is restored, the boiler will restart automatically.
In case of loss of water in the system
CAUTION: The boiler is installed as part of a sealed system which must only be drained and filled by a competent
person.
If the pressure shown on the pressure gauge is less than 1 bar the system must be filled up immediately.
Important notice: A central heating system cannot operate satisfactorily unless it is properly filled with water and
unless the air initially contained in the piping systems has been properly bled off. If these conditions are not
satisfied, air noise will occur within the system and the boiler may fail to operate.
Air in the heating system
Persistent air in the heating system may indicate leaks in the system or corrosion taking place. Call your Installer
/Service provider.
Overheating safety
In the event of problem, the overheat safety device causes safety shutdown of the boiler. If this happens, call
your Installer/Service provider.
CONTROLS AND LIGHTING
The control panel is located behind the drop down front door. The controls on this panel allow the boiler to be
started, shut down, controlled and monitored during use, see diagram 1.
Controls
1 - Timeclock 5 - Summer/Winter switch
2 - Pressure gauge 6 - Reset button
3 - Hot water temperature control 7 - Mains On/Off switch
4 - Heating temperature control 8 - Digital display

Make sure that:
• The boiler is connected to the electrical supply.
• The boiler gas service cock is open.
• The pressure gauge reads between 1 and 2 bar.
The boiler is now ready to start.
To start the boiler
• Place switch (7) in the On position “I”
• Place switch (5) in the desired Summer or Winter position
To stop the boiler
Place switch (7) to the Off position “O”.
If the boiler is to be out of operation for a long period, turn off the gas service cock.
Setting to ‘Summer’ mode (Hot water only)
Place switch (5) in the Summer position
Setting to ‘Winter’ mode (Heating and hot water)
Place switch (5) to the Winter position
Adjust the heating temperature control (4) to the desired temperature.
Adjust the domestic hot water control (3) to the desired hot water temperature. The heating will operate according to the requirements of the timeclock and/or room thermostat if fitted or, will operate according to the system
requirements.
Domestic hot water always has priority over central heating.
Timeclock
The boiler can be switched on and off automatically by the built-in timeclock. To set the timeclock, proceed as
follows: (refering to diagram 1)
Press in the tappets corresponding to the time you want the boiler to be on.
For example if you want the boiler to be on between 7 AM and 9 AM, push in all the tappets between
7 and 9.
Set the times you want the boiler to be on for the rest of the day in the same way.
Note: The timeclock setting is in 24 hour format. Therefore, if you want the boiler to come on at 2 PM you must push
in the tappets at 14.
To set the correct time rotate the clock by hand until the current time is indicated by the arrow at the top of the
clock.
To operate the boiler according to your selected times, place the grey lever to the position.
To have the boiler permanently ‘ON’, place the grey lever to the ‘I’ position.
To have the boiler permanently ‘OFF’, place the grey lever to the ‘0’ position.
Safety lockout
In the event of a safety lockout, the digital display will show ‘F1’.
Reset boiler by pressing the RESET button (6).
IMPORTANT: If safety lockout occurs frequently, or if any other fault is indicated, contact your Installer/Service
Provider.
Draining and filling
CAUTION: The boiler is installed as part of a sealed system which must only be drained and filled by a competent
person.
Note: If there is persistent loss of system pressure, you must consult your Installer/Service Provider.
If the pressure shown on the pressure gauge is less than 1 bar the system must be filled immediately.
Heating safety valve
CAUTION: A safety valve with a discharge pipe is fitted to this boiler.
The valve MUST NOT BE TOUCHED except by a competent person. If the valve discharges at any time, switch
the boiler off and isolate it from the electrical supply. Contact your Installer/Service Provider.
Servicing/Maintenance
To ensure the continued efficient and safe operation of the boiler, it is recommended that it is checked and
serviced at regular intervals. The frequency of servicing will depend upon the installation conditions and usage
but, in general, once a year should be enough.
Cleaning
The boiler casing can be cleaned with a damp cloth followed by a dry cloth to polish.
Do not use abrasive or solvent cleaners.
Boiler casing
CAUTION: Do not remove or adjust the casing in any way, as incorrect fitting may result in faulty operation.
If in doubt, contact your Installer/Service Provider.

INSTALLATION INSTRUCTIONS
Introduction
The Protherm 100 e is a wall mounted combination boiler providing central heating and instantaneous domestic hot
water.
The boiler is of the II
2H3+
category for use with Natural gas (G20) as distributed in the United Kingdom, or with
Butane or Propane gas (G30/G31) with the appropriate conversion kit.
Conversion kit:
Conversion Part No.
Natural gas (G20) to G30/G31 . . . . . . . 92321165
Modification must only be carried out by a suitably qualified engineer.
Boilers burning LPG or similar gases MUST NOT be fitted in basements or below ground level.
These instructions should be carefully followed for the safe and economical use of your boiler.
The boiler has a fan assisted, balanced, flue which both discharges the product of combustion to, and draws the
combustion air from the outside of the building.
Accessories
A range of accessories are available including, vertical flue components. For further information, contact you nearest stockist.
Gas Safety (Installation and Use) Regulations
In the interests and that of gas safety, it is the law that ALL gas appliances are installed and serviced in by a competent
person in accordance with the above regulations.
Gas leak or fault
If a gas leak or fault exists or is suspected, turn the boiler and gas supply off and consult the local gas company or
your Installer/Service Provider.
Boiler controls
The control panel, located at the lower front of the boiler, allows the boiler to be started, shut down, controlled
and monitored during use, refer to ‘Users Instructions’.
