Flagro FV-VK Flue Stack with Rain Cap 6 Inch 24 Inch

Product Description

The FLAGRO FV-VK is a 6-inch diameter flue stack with integrated rain cap, measuring 24 inches in length, designed as an OEM accessory for FLAGRO FV-series indirect-fired portable heaters. It provides a vertical exhaust path that routes combustion gases away from the conditioned space. The rain cap prevents moisture and debris from entering the flue opening during operation or when the unit is at rest. At 12 pounds, it is a field-serviceable replacement component installed by HVAC technicians, rental fleet mechanics, and construction equipment service personnel maintaining temporary heating systems.

This flue stack is intended for temporary heating applications where indirect-fired portable heaters are deployed, including construction sites, large tented structures, industrial facilities, and similar commercial or industrial environments. Indirect-fired units recirculate clean air internally while venting combustion byproducts externally, making a properly fitted and secured flue stack essential for safe operation. The FV-VK connects directly to the heater exhaust outlet and provides the vertical clearance needed for adequate exhaust gas discharge in the field.
