in accordance with the requirements of BS6891.
Ensure that the pipe size is adequate for demand
including other gas appliances on the same supply.

exceeding 6 bar, particularly at night, then a suitable
pressure limiting valve must be fitted.
The boiler is designed to provide hot water on
demand to multiple outlets within the property.
If there is a requirement for greater demands, for
example if the boiler has several bathrooms and
cloakrooms, a vented or unvented hot water storage
system may be used.
Showers
Any shower valves used with the appliance should
be of a thermostatic or pressure balanced type.
