www.centralheating.co.uk
Please ensure that the installer has fully completed the Benchmark Checklist on the inside back pages of the
installation instructions supplied with the product and that you have signed it to say that you have received a full
and clear explanation of its operation. The installer is legally required to complete a commissioning checklist as a
means of complying with the appropriate Building Regulations (England and Wales).
All installations must be notified to Local Area Building Control either directly or through a Competent Persons
Scheme. A Building Regulations Compliance Certificate will then be issued to the customer who should, on receipt,
write the Notification Number on the Benchmark Checklist.
This product should be serviced regularly to optimise its safety, efficiency and performance. The service engineer
should complete the relevant Service Record on the Benchmark Checklist after each service.

1. GENERAL INFORMATION
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: IT IS A STATUTORY REQUIREMENT THAT ALL GAS APPLIANCES BE INSTALLED BY
COMPETENT PERSONS, (i.e. GAS SAFE REGISTERED INSTALLERS. GAS SAFE MEMBERSHIP
ENQUIRIES - TEL: [phone]) IN ACCORDANCE WITH THE GAS SAFETY (INSTALLATION AND
USE) REGULATIONS (CURRENT EDITION). FAILURE TO COMPLY WITH THESE REGULATIONS MAY
RESULT IN PROSECUTION.
Part of the installation and commissioning of this appliance is related to instructions for use by the heating
engineer to the user where specific requirements may occur.
The QuanTec is a wall mounted, room sealed, condensing combination boiler, featuring full sequence
automatic spark ignition and fan assisted combustion. On the QuanTec HR a recuperator is fitted within the
boiler and preheats the incoming cold DHW for additional energy savings. Due to the high efficiency of the
boiler, condensate is produced from the flue gases and this is drained to a suitable disposal point through a
plastic waste pipe at the base of the boiler. A condensate ‘plume’ will also be visible at the flue terminal. The
QuanTec HR are combination boilers providing both central heating and instantaneous domestic hot water.

3. TO LIGHT THE BOILER
3.1 Switch the mains power ON and the boiler LED display will show “AP”. This puts the
boiler into the Air Purge Mode. See Figure 2.
3.2 Press the reset button “K4” twice. The boiler will go onto standby. This is the winter
mode.
SETTING THE DHW WATER TEMPERATURE
3.3 To set the hot water temperature press and hold “K7”, this will flash until the °C
temperature shows. By pressing the + and - buttons to set the desired temperature. The
temperature flashes 5 times to set the temperature and then goes back onto standby.
SETTING THE CH WATER TEMPERATURE
3.4 To set the central heating temperature press and hold “K1”, this will flash until the °C
temperature shows. By pressing the + or - buttons to set the desired temperature.
The temperature flashes 5 time to set the temperature and the display will go back to
standby.
4. OPERATING FUNCTIONS
4.1 OPERATING THE DOMESTIC HOT WATER
When the call for hot water is needed the boiler will fire. The display will show the full
flame, tap and the set water temperature. This will flash until the need for hot water is
satisfied. See Figure 4.
4.2 OPERATING THE CENTRAL HEATING
When the boiler fires in CH mode it fires for 1 minute, modulating the boiler. The display
will flash showing the radiator, the small flame and temperature. The flame symbol
increases with the demand for heat. Once temperature is reached the display will go
back to standby. See Figure 5.
Approximate flow temperatures for the boiler thermostat settings are:
4.3 DISPLAY CODES
In normal operation the boiler LED display will show codes:
1. Standby - no demand for heat.
2. CH being supplied.
3. DHW being supplied.
4. Boiler frost protection - boiler will fire if temperature is below 5°C.
5. During normal operation the burner on indicator will remain illuminated when the burner is lit.
Note: If the boiler fails to light after five attempts the fault code will be displayed.
4.4 TO SHUT DOWN THE BOILER
Set the mode to OFF by pressing K4.
To relight the boiler repeat the procedure detailed in ‘To light the boiler’.
4.5 FROST PROTECTION
If no system frost protection is provided and frost is likely during a short absence from home, leave the
heating controls (if fitted) at a reduced temperature setting. For longer periods, the entire system should be
drained.
If the system includes a frost thermostat then, during cold weather, the boiler should be turned OFF at the
time switch (if fitted) ONLY. The mains supply should be left switched ON, with the boiler thermostat left in
the normal running position.

4.6 LOSS OF SYSTEM WATER PRESSURE
The pressure gauge indicates the central heating system pressure. If the pressure is seen to fall below the
original installation pressure of 1-2 bar over a period of time then a water leak may be indicated. In this event
conduct the re-pressurising procedure. If unable to do so or if the pressure continues to drop a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII) should be consulted.
The boiler will not operate if the pressure has reduced to less than 0.3 Bar under this condition.
1. Ensure filling loop isolation valves are closed.
2. Remove the two caps
3. Attach on the filling loop.
4. Turn the filling loop isolation valves to the open position. The system will now fill.
5. Wait for pressure gauge dial to reach 1 to 1.5 bar.
6. Close the filling loop isolation valves.
7. Disconnect the filling loop at left hand side and angle upwards.
8. Attach the two blanking caps.
4.7 CONDENSATE DRAIN
The condensate drain must not be modified or blocked.
Blockage of the condensate drain, caused by debris or freezing, can cause automatic shutdown of the
boiler.
If freezing is suspected and the pipe run is accessible an attempt may be made to free the obstruction by
pouring hot water over the exposed pipe and clearing any blockage from the end of the pipe. If this fails to
remedy the problem the assistance of a Gas Safe Registered Engineer or in IE a Registered Gas Installer
(RGII) should be sought.
5. RESET THE BOILER
Press the reset button “K4” twice.
6. SERVICING & MAINTENANCE
It is recommended that a full maintenance check be carried out annually on the appliance. It is also
recommended to take out a further service agreement on the expiry of the guarantee period.
You can obtain further information on this from your gas supplier.
The appliance should be checked /serviced by a GAS SAFE registered installer.
If you require service on your appliance please contact your local installer or gas supplier.
On completion of the service the installer should fill in the service section at the rear of the BENCHMARK
Checklist. All installers registered with GAS SAFE carry an identification card. This card will have an ID
number which should be recorded in your logbook.
If you have any queries regarding your installer you can contact GAS SAFE
by telephone on 0800 408 5500.
The appliance should be serviced at least once a year by a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII).
7. ESCAPE OF GAS
Should a gas leak or fault be suspected contact the National Gas Emergency Service without delay.
Telephone [phone]
Do NOT search for gas leaks with a naked flame.
8. CLEANING
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains, wipe with a damp cloth and finish off with a dry cloth.
DO NOT use abrasive cleaning materials.
