Installation Guide:

Installing Your Product

The 316 should be installed (a minimum of 3 x diameter) from any combustible materials, e.g. 125mm pipe should be 375mm from combustible materials.

Can be used as a substitute for a flexible flue liner.

The 316 stainless steel must only be used to connect from the appliance to flexible liner or twin wall insulated system. It must NOT be used externally and where there is a risk of combustibles being placed next to the chimney, the minimum distances to combustibles must be maintained whether by a permanent enclosure or shield. Please refer to the Document J Building regulations for more information.

The 316 should be fitted with socket uppermost, spigot (male end) downward to avoid condensate escaping.

Each joint should be sealed with fire cement or high temperature silicone sealant to ensure a gas tight fit.

Where 316 single wall flue passes through a brick internal wall, it is recommended a wall sleeve is used around the pipe. 

Provision for sweeping and inspections must be made.

The chimney diameter should never be reduced to less than the diameter specified by the appliance manufacturer. An 
increase in size may be required.

Ensure that adequate air is available for combustion.

Components must NOT be modified for safety reasons.

A chimney notice plate and carbon monoxide detector must be installed in the building, preferably in the same room as the appliance.

The installation must be commissioned by a registered installer in-line with the Building Regulations (Document J). If there are any leaks or issues with the system, it must not be used until the problems have been rectified.

Provisions must be made for condensate drainage where appropriate.

Please refer to the Document J Building regulations for more information.
