The Navien LCB Plinth is designed to provide a stable and protective base for external Navien oil and gas-fired combi boilers. It elevates the boiler above ground level to reduce exposure to standing water, debris, and uneven surfaces, helping maintain long-term structural support and installation safety.
The plinth forms part of an External Boiler Accessories setup and ensures correct height positioning to support condensate drainage, service access, and compliance with outdoor installation requirements. It is constructed from robust, weather-resistant materials suitable for permanent installation outside the property.
This component integrates with Navien’s external boiler ranges and is suitable for both new installations and retrofitting where additional support or clearance is required.
- Provides a stable base for external Navien combi boilers
- Raises boiler above ground level for improved protection
