    APPENDIX 1 (GUIDANCE HHIC - October 2018 Issue 1.0) Manufacturer's Instructions The latest manufacturer’s instructions shall be followed for the correct connection of the condensate discharge pipe from the boiler as this may vary due to the design of the boiler. For example, a trap is not required in the condensate discharge pipework if there is a trap with a minimum condensate seal of 75 mm incorporated into the boiler.

  • Page 50 Internal Condensate Pipe Discharge Termination When connecting to existing pipework it is critical to review the existing installation to ensure the existing pipework is appropriate for condensate discharge having been run correctly and fully insulated and sealed if this is an external or internal termination. The possibility of waste pipes freezing downstream of the connection point shall be con- sidered when determining a suitable connection point - e.g.
  • Page 51 External Connections External Connections External Connections Only fit a correctly insulated external boiler condensate drain connection if an internal gravity or pumped connection is impractical to install. The pipe work from the boiler shall be of a minimum 19mm ID or if in an unheated area increased to 30mm ID (typically 32mm OD) solvent weld of as per manufacturer’s instructions and the condensate discharge pipe shall be run in a standard drainpipe material, e.g.

  • Page 53 External Connections onnecting to a rain water downpipe/External Soil Stack When a rain water downpipe is used as the termination (NB only permissible if this downpipe passes to a combined foul and rainwater drainage system) an external air break shall be installed between the condensate discharge pipe and the downpipe to avoid reverse flow of rainwater into the boiler should the downpipe itself become blocked, flooded or frozen.

  • Page 57 Other considerations Unheated Areas in Buildings Internal condensate drainage pipes run in unheated areas such as lofts, basements and garages shall be treated as external connections and insulated accordingly. Weather proof materials may not be necessary but where separate sections of insulation join together, including elbow joints then these should be connected, insulated and sealed correctly to prevent them coming apart with a suitable material to help prevent freezing.
  • Page 58 Alternative Solutions Cold weather protection Cold weather protection methods approved or endorsed by boiler manufacturers and/ or service organisations may be adopted if these are considered suitable by the parties involved. It is the responsibility of the manufacturer of these products to ensure they have completed the necessary testing or calculations to ensure the product offers suitable protection to prevent the condensate pipe from freezing.
