The Navien NCB300/500 Stand Off Kit is designed to provide additional wall clearance for Navien NCB300 and NCB500 gas boilers. It creates space behind the boiler to allow pipework to pass vertically or horizontally, improving installation flexibility where rear or side connections are required.
This kit is used within a Boiler Mounting Accessories setup and is fitted between the boiler and the wall surface. The spacing allows easier routing of flow, return, gas, and condensate pipes while maintaining secure boiler support and compliance with installation guidelines.
Manufactured from durable steel components, the stand off kit forms part of Navien’s boiler accessory range and is suitable for new installations or retrofits where pipework access is limited.
- Provides additional wall clearance for pipe routing
- Designed for Navien NCB300 and NCB500 boilers
