Building Regulations and the Benchmark Checklist

Building Regulations (England & Wales) require notification of the installation of a heating
appliance in a dwelling to the relevant Local Authority Building Control Dept. This can be
achieved via a Competent Persons Self Certification Scheme as an option to notifying the Local
Authority directly. Similar arrangements apply in Scotland and Northern Ireland.
Atmos Heating Systems is a member of the Benchmark Scheme and the Benchmark Checklist
is included at the back of these Instructions. The Benchmark Checklist provides a
Commissioning Checklist and Service Record to be completed by the Installer/ Service
Engineer.

Benchmar

k places responsibilities on both manufacturers and installers.

The purpose is to ensure that customers are provided with the correct
equipment for their needs, that it is installed, commissioned and serviced in
accordance with the manufacturer’s instructions by competent persons and
that it meets the requirements of the appropriate Building Regulations. The
Benchmark Checklist can be used to demonstrate compliance with Building
Regulations and should be provided to the customer for future reference.

Installers are required to carry out installation, commissioning and servicing
work in accordance with the Benchmark Code of Practice which is available
from the Heating and Hotwater Industry Council who manage and promote
the Scheme. Refer to www.centralheating.co.uk for more information.

Atmos Warranty – Short version

1. Atmos Warranty covers any material, construction or operation faults
that are found to be of original manufacturing origin. A full statement of
the Atmos Warranty can be found on www.atmos.co.uk.

2. Atmos boiler warranty is two years from date of invoice or 12 months
from date of installation, whichever is the later. This warranty covers the
cost of replacement parts and associated labour. However the ignition &
ionisation probe and the glass fuse are excluded from this warranty. The
warranty for the heat exchanger is 10 years in total, but this covers the
cost of associated labour only for the first two years from date of invoice.

3. There is no carriage charge for the delivery of replacement parts
covered by the warranty. Any alleged faulty part must be returned to
Atmos carriage prepaid. Carriage will be credited if the fault is found to
be a manufacturer’s fault.

4. The serial number of the boiler must be supplied with any warranty
claim.

5. All products must be used in an appropriate application and manner.
This includes, but is not limited to, correct boiler sizing, system design,
system cleansing and use of corrosion inhibitors. If the boiler installed is
a combi boiler, an approved water conditioner device must be fitted in
areas where the water hardness exceeds 200ppm, as required by
Building Regulations.

6. The Benchmark Checklist & Service Record, found in the back of the
installation Instructions, must be filled in. Failure to install and
commission according to the manufacturer’s instructions and complete
the Benchmark Commissioning Checklist invalidates the warranty.

7. The Warranty card must be completed and the signed Atmos copy must
be received within 14 days of installation together with a copy of the
Benchmark Commissioning Checklist, completed by the installer. By
signing the Warranty card the buyer agrees that the goods have been
delivered in a satisfactory condition.

Exceptions

8. In the event of full payment for a product not being received, Atmos
shall be discharged from all further contractual or warranty obligations.

9. Surface and/or transport damage are outside the scope of this warranty.

10. Any warranty provision shall not apply if Atmos determines that the fault
is due to improper application, use, neglect, accidental damage or
injudicious treatment, non-observance of instructions contained in
Atmos Manuals or due to improper repair, adjustment, installation or
maintenance or due to work carried out by unqualified engineers. The
warranty also lapses if the Atmos boiler has not had a yearly service in
accordance with instructions.

11. This warranty shall not apply if the fault is caused by scale, failure or
abnormality of gas or water supply, or impact of any external influence
that adversely affects the normal operation of the product. This shall
include but not be restricted to dehydration, abnormal or high voltage,
and hard water.

12. Excluded parts are the ignition & ionisation probe and the glass fuse as
these are subject to wear and tear in normal use.
