Description Overview The Rytons DVKIT100MG is a 100 mm direct ventilation kit designed to supply combustion air directly from outside into your Hamer Basset 5 stove. Rather than drawing air from the room, this kit ensures your stove breathes fresh external air — helping improve performance, reduce unwanted draughts, and maintain more stable internal air conditions. Compatibility & Purpose The Hamer Basset 5 is a modern multi‑fuel / wood-burning stove that benefits from a dedicated air supply, especially in well‑sealed modern homes or where external vents are undesirable. The DVKIT100MG allows connection to the stove’s air inlet and channels air from outside through rigid/semi-rigid ducting, ensuring the stove is partially or fully room-sealed (depending on installation). Because the kit supplies combustion air directly, there is no light or drafts entering the room. It is especially useful in homes with tight building fabric, extractor fans, or limited natural ventilation. Kit Contents & Construction Stainless Steel Cowled Meshed Grille (RD4MGSS): External vent grille (147 mm flange × 68 mm depth) with 96 mm male spigot. Made of stainless steel for durability. Semi‑Rigid Aluminium Ducting: 102 mm diameter × 1.5 m length, made of non-combustible aluminium (DIN 4102 Class A1) suitable up to 250 °C. Metal Hose Clips (×2): For secure connection of ducting to the stove and grille. Key Features & Benefits Non‑combustible ducting: Designed to withstand up to 250 °C safely. rts.vents.co.uk Reduced draughts & heat loss: By sourcing air externally, the stove will not draw warm room air, improving overall efficiency. Cleaner, stable burn: More consistent air supply leads to better combustion performance. Discreet installation: The grille is designed to minimize visual impact and is mesh-protected to block debris or ingress. Easy to integrate: Connects directly to the stove’s inlet and external wall with standard duct. Installation Considerations Ensure the duct route is as direct and short as possible to reduce pressure losses. Seal all joints carefully to prevent leakage. Verify the stove’s air controls (primary/secondary) are compatible with external air supply — some stoves only partially draw air from the duct. Building regulations or installer guidelines may require permanent ventilation in new-build or highly airtight properties. Stovefitter’s Warehouse 2UK Workshop 2 The external grille must be placed where it won’t be obstructed and it should include screening to prevent blockages.
