Rain Cap with Spark Guard for Chimney

Product Description

The Rain Cap with Spark Guard is a specialized top component for three-layer chimneys that performs two functions: it protects the channel from precipitation and prevents hot sparks from escaping. Its primary function is to act as a spark arrestor. This is a mandatory component for saunas, open fireplaces, or in cases where the roof or nearby buildings are made of combustible materials.

Key Features

  • Effective Spark Protection: The principle is simple and reliable. The flow of flue gases with sparks first hits the cap, changing direction, and then passes through the fine-mesh screen. The spark guard breaks up and extinguishes embers upon contact with the metal mesh.
  • Protection from Precipitation and Birds: It performs all the functions of a standard rain cap—protecting from rain and snow. Additionally, the mesh serves as an impassable barrier for birds and small animals that might try to build a nest in the insulated chimney.
  • Reliable Construction: It is manufactured as standard from heat-resistant stainless steel AISI 304 / 316L with a thickness of 0.6 mm. The mesh size (10x10 mm or 20x20 mm) is large enough for the free passage of smoke but effective for catching sparks.
  • Optimized to Preserve Draft: Like a standard rain cap, the spark arrestor is designed to have a minimal effect on the draft, provided that the mesh is cleaned regularly.

Application & IMPORTANT RESTRICTIONS

  • REQUIRES REGULAR CLEANING: Over time, the spark arrestor mesh will become clogged with soot. A clogged mesh severely impairs the draft and can lead to smoke entering the room. It is necessary to inspect and clean the mesh regularly (at least 1-2 times per season).
  • Fuel Restrictions: It is strongly recommended not to use the spark arrestor when burning resinous woods (pine, spruce) or damp firewood, as this leads to rapid clogging of the mesh with creosote.
  • Alternative Solution: If spark arresting is not a mandatory requirement, it is recommended to use a standard rain cap (cowl) for better draft and simpler maintenance.
