3. ESSENTIAL INSTALLER CHECKS TO BE MADE PRIOR TO INSTALLATION
3.1. Carry out all heat loss calculations on the property and make sure that this boiler is suitable for the
installation. EHS can assist with these calculations. Should you require this service please contact
[email protected]. HEAT LOSS CALC DONE?
3.2. For combination boilers you will need to carry out a hot water calculation to ensure that the boiler has a
sufficient heat output to provide the correct temperature & flow of water required for the application.
This will depend on flowrate required. If you need help calculating this, please contact info@ehs-
heating.com. HOT WATER CALCULATION DONE?
3.3. Check the mains water pressure - The maximum pressure of the units is 6bar, where water pressure is
close to or varies around this limit a pressure reducing set on the mains supply should be installed.
MAINS WATER PRESSURE CHECK OK?
3.4. Check that the power supply to the premises meets the minimum requirements of the unit being
installed. PREMISES POWER SUPPLY SUFFICIENT?
3.5. Carry out a voltage and load test to determine the correct sized cable and breaker is used. VOLTAGE
AND LOAD TEST DONE? CABLE SIZE mm? BREAKER (AMPS)?
3.6. Check the central heating design is suitable for the application (Detailed recommendations are provided in
BS EN 12828 and BS EN 6700.) SYSTEM DESIGN
COMPATIBLE WITH PART L OF THE BUILDING REGULATIONS
3.7. If installing a combination boiler, check that the hot water flow rate from the boiler will be sufficient for
the application.
HOT WATER FLOWRATE OF COMBI BOILER SUFFICIENT?
3.8. When siting the boiler, consider the requirements for servicing the boiler (i.e. space around and in front of
the boiler) and ensure that it is fitted in a location that cannot be accessed by unauthorised/unqualified
people or children.
3.9. Make sure that this boiler is not installed in a shower compartment or bathroom.
3.10. The Boiler must be installed in an Upright position
3.11. Check that the boiler will be mounted on a suitable wall that can bare the weight of the boiler.

7. Installation steps
7.1. Positioning and Wall Mounting the Boiler
IMPORTANT:
When choosing a location to mount the boiler it is important that you consider clearance, servicing
of the boiler, and safe and suitable operation.
When power is supplied, the boiler should only ever be opened by a qualified electrician after first
isolating the electrical supply.
The boiler should be fitted out of the reach of children and people without the right skills and
qualifications. If there is the possibility that the boiler could be opened without first isolating the electrical
supply then you must install it in a fashion that prevents access to the boiler, such as a lockable cupboard.
The wall that you choose to mount this boiler on should be strong enough to support the boiler
when full.
EHS recommend at least 100mm clearance from all fixed obstructions on all sides of the boiler. Allow plenty of space
at the base of the boiler for fitting the hot and cold-water pipes and isolation valves.
Step 1. Drill 5 holes as per the included wall mounting diagram. The upper 3 holes should be Φ8mm
diameter, and the lower 2 holes Φ6mm.
Step 2. Secure the 3 Φ8mm expansion bolts into the top three holes
Fig 1 Fig 2
Step Three : Hang the boiler from the top three bolts before securing the boiler to the wall using standard
fastenings at the bottom
10 www.ehs-heating.com
Screw 3 x screws into 3 upper expansion screw bolts
Step Four: Hang the boiler on the 3 fixed screws. Then drill 2 screws into 2 under expansion screws
