The Viessmann PlusBus Spacing Frame (90mm Clearance) for Vitodens 100‑W Combi and System boilers is a stand‑off mounting solution designed to create 90mm of rear clearance so that all pipework can be routed neatly behind the boiler. This ensures a clean, streamlined finish while maintaining full service access and compatibility with front‑facing PlusBus connections.

It is ideal for modern installations where visible pipework needs to be avoided or where space behind the boiler is required for tidy, concealed routing.
