Burnham Baseray 9A3C – 3-Foot Cast Iron Baseboard Complete Assembly
The Burnham Baseray 9A3C is a three-foot sectional cast iron baseboard radiator designed for use in residential and light commercial hydronic heating systems. Engineered for durability and optimal heat transfer, this unit combines a compact footprint with the proven performance of cast iron heating technology.
Product Overview
Ideal for perimeter baseboard installations, the 9A3C complete assembly includes a 1.5-foot left and a 1.5-foot right panel joined at the center. Each section features integral legs for floor-mounted support and is designed to connect easily to additional panels for larger configurations. The cast iron construction delivers steady, uniform heat with minimal thermal fluctuation and noise.
Key Performance Attributes
Material: High-density cast iron for extended thermal mass and consistent room temperature
Output: Provides approximately 10.2 square feet of Equivalent Direct Radiation (EDR), translating to ~612 BTU/hr at standard ratings
System Compatibility: Fully compatible with hot water and low-pressure steam boiler systems
Installation: Floor-mounted with factory-integrated support legs and closed-end design
Noise-Free Operation: Solid cast iron structure eliminates pinging or expansion noise associated with fin-tube systems
Applications
Perimeter zone heating in retrofit or new installations
Basement and first-floor runs where radiant mass and low-profile operation are preferred
Residential projects requiring silent performance and high thermal inertia
Technical Specifications
Model: Burnham Baseray 9A3C
Total Assembly Length: 3 feet

Finish: Factory-applied primer, suitable for field painting
Weight: Approx. 90 lbs
Connection: 1-1/4" NPT tappings
Installation Notes
Due to its weight and system integration requirements, this assembly should be installed by a qualified HVAC or plumbing technician. Ensure appropriate support and coupling for adjacent sections, proper boiler sizing, and compliance with applicable building codes. The unit is shipped in a complete configuration, requiring only connection to the supply and return lines.
Additional Considerations
Custom Sizing: Sections can be joined with couplings for extended lengths
Paintable Surface: Primer finish accepts standard baseboard paints
High Radiant Output: Baseray units provide up to 5x more radiant energy than standard fin-tube baseboard designs
Low Clearance: Efficient use of wall space in tight mechanical layouts
