The MESTEK 1144136040 is a 30-foot body extension package designed for RSS Series radiant heating systems. Constructed from hot rolled steel, this extension adds length to an existing radiant tube heater installation, allowing coverage of longer run applications in commercial and industrial spaces. The package ships as a complete kit including reflectors, couplings, and mounting brackets, reducing the need to source hardware separately. Licensed HVAC technicians and mechanical contractors typically specify this component when extending radiant tube runs in warehouses, manufacturing facilities, and large open-bay environments.
This body extension is intended for use with the RSS Series radiant tube heater product line. It is well suited for single-stage or staged radiant heating installations in high-bay commercial and industrial buildings where extended tube runs are required to distribute heat evenly across a large floor area. The included reflectors, couplings, and brackets support a complete and code-consistent installation without additional field fabrication of mounting hardware.
Designed as a direct-fit body extension for RSS Series radiant tube heater systems. No other specific compatible model numbers or part numbers were identified in the available product data.
Installation should be performed by a licensed HVAC or mechanical contractor familiar with radiant tube heater systems and applicable local mechanical codes. Shut off all gas supply and disconnect electrical power to the heater before beginning any extension work. Follow the manufacturer installation instructions for proper coupling alignment and bracket spacing to maintain structural integrity and safe clearance-to-combustibles distances. Reflectors should be secured and oriented per the system design to ensure proper heat distribution.
