Field Controls 46521801 CV-4 Telescopic Stainless Steel Combustion Vent Termination

The Field Controls CV-4 ComboVent Power Venter combines motor, blower, and vent hood in one complete unit that mounts on the outside of buildings and pulls combustion gases through exterior walls using 100% negative pressure. This model features a 4-inch telescopic stainless steel construction with an integrated combination air inlet.

Key Features:

• Telescoping stainless steel body accommodates walls up to 14 inches thick
• Coupler rotates 360 degrees for easy installation with CAS boot
• Slotted hood design with larger screws saves time during annual service and allows easy motor access
• Combination air inlet provides combustion air supply alongside exhaust venting
• 4-inch inlet diameter suitable for residential and light commercial applications

The CV-4 is designed for use with gas or oil furnaces, boilers, and water heaters in new construction, when converting from electric to gas or oil, to avoid relining a chimney, or when co-venting with additional appliances. This ComboVent must be installed with a CK Control Kit to ensure proper listing and safe, efficient venting. Professional installation by a licensed contractor is recommended for optimal performance and code compliance.
