Product Description

The SPNP Bottom Cap is a key single-wall flue component made from black carbon steel that provides a pressure-tight seal for the chimney system. It securely closes the bottom spigot of a tee piece, preventing the leakage of flue gases under pressure and ensuring stable boiler operation. This component is used in installations where a dedicated condensate drain is not required. The cap is easily removable to provide access for periodic cleaning of the flue channel.

Key Features

• Pressure-Tight System Seal: Securely closes the bottom outlet of a tee, preventing flue gas leakage and ensuring the safety of the system under positive pressure.
• Access for Maintenance: The cap is easily removable, providing direct access to the base of the tee, which acts as a natural soot collector. This allows for quick and convenient cleaning and inspection of the vertical run.
• Durable Senotherm Coating: The component is coated with a black matte heat-resistant paint that withstands operating temperatures up to 200°C and matches the finish of most European boilers.
• European Quality and Safety: The product is certified and CE marked, confirming its full compliance with the European standard for flue systems EN 1856-2.

Important Limitations

• For Pellet Appliances Only: Do not use with wood-burning stoves, open fireplaces, or other solid fuel boilers where flue gas temperatures exceed 200°C and there is a risk of soot fire.
• No Condensate Drain: This cap does not have a drain outlet. For systems where significant condensation is expected, using a cap with a dedicated condensate drain is recommended.
