Reznor 136965 Power Venter Kit 115V Single Phase with 24V Relay

The Reznor 136965 is a CA1 power venter kit designed for gravity-vented unit heaters operating in negative pressure environments or requiring horizontal venting. This complete kit is engineered for 350-400 MBTUh unit sizes and operates on 115V single-phase power with an integrated 24V relay control system.

Key Features:

• Complete CA1 venter assembly for 350-400 MBTUh Reznor unit heaters
• 115V single-phase operation with maximum permissible voltage of 127V
• Factory-assembled venter includes motor, blower wheel, pressure switch, time delay relay, and junction box
• Motorized exhaust venter allows installation in areas with negative pressure up to 0.15 IN WC
• Centrifugal blower with forward-curved blades, statically and dynamically balanced
• 2-pole motor with nominal 3,000 RPM for reliable performance
• Integrated 24V relay for thermostat control and safety interlocking
• Corrosion-resistant steel housing for long service life
• Includes venter flue adapter and complete parts bag for installation

This power venter kit controls dilution air flow through the drafthood and vent pipe to ensure safe and efficient operation. The pressure switch wires in series with the thermostat to verify proper venter flow before allowing gas valve operation, providing critical safety protection. When the thermostat calls for heat, the venter starts after approximately 30 seconds, and the pressure switch closes to complete the circuit to the burner controls.

Application: Designed for Reznor Model F (fan) and Model B (blower) gravity-vented unit heaters requiring forced draft venting. Essential for installations in areas with insufficient natural draft or where horizontal venting is necessary.
