DO NOT ATTEMPT TO VENT THE PRIMARY CIRCUIT THROUGH THE EXCELSIOR UNIT.
ALL EXTERNAL HEAT SOURCES SHOULD BE INSTALLED TO MANUFACTURERS INSTRUCTIONS AND THE PRIMARY CIRCUIT

Benchmark Scheme Checklist
Benchmark 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. The Benchmark Code of Practice is available from the Heating and Hot
Water Industry Council, who manage and promote the scheme
.
Visit www.centralheating.co.uk for more information.
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.
Siting the Excelsior unit
Note: Excelsior cylinders are designed for indoor use only
The unit can be placed anywhere convenient. Since it is connected directly to the mains water supply it is equally efficient
on any floor – ground, first or second. Avoid areas that may be subject to frost
.
Try to keep pipe runs as short as possible
for maximum economy, especially hot water discharge pipes running down from the Excelsior unit.
The unit can be fitted into a conventional airing cupboard and does not require any additional insulation.
The water supply to the cylinder should be potable water direct from a public mains supply with any water treatment
equipment functioning correctly.
Vertical cylinders
If installing a vertical cylinder, ensure it is fixed securely in an upright position for correct operation.
Horizontal cylinders
If installing a horizontal cylinder, ensure it is fixed securely with the temperature and pressure relief valve positioned at the
top for correct operation.
Storage & Handling
If the cylinder is not being installed immediately, it should remain in its protective wrapping with all pipe end protective
caps in place to prevent damage.
Connecting the Water Supply
Pipework is not supplied.
All pipework should be installed using good plumbing practice. We recommend 22mm mains cold water supply is used.
Install a stop cock valve before the cold water inlet assembly on the incoming mains water supply so the unit can be
isolated if required.
