Field Controls 46139981 750mv Control Kit Power Venters

Product Description

The FIELD CONTROLS 46139981 is a 750mV control kit designed for use with power venters on gas-operated heating units. Also known as the CK-81, this kit provides the low-voltage switching logic needed to coordinate a power venter with either a remote thermostat or a simple on/off switch. It allows the venter to prove airflow before the gas valve opens, a critical safety function in standing-pilot and millivolt heating systems. Licensed HVAC technicians and gas appliance service pros install this kit as part of a complete venting control assembly on residential and light commercial gas-fired equipment.

The 46139981 is suited for millivolt gas appliance systems where 750mV pilot generator output drives the control circuit. Typical applications include gas fireplaces, floor furnaces, wall heaters, and similar standing-pilot units that require power venting. This kit accommodates installs where a remote thermostat or an on/off switch serves as the primary user control, making it adaptable to a variety of field configurations without adding line-voltage complexity to the circuit.

Key Features

• Designed for 750mV millivolt control circuits common in standing-pilot gas appliances
• Compatible with remote thermostat or on/off switch configurations
• Coordinates power venter operation with gas valve sequencing for safe draft proving
• Factory model designation CK-81 for direct ordering and warranty reference
• Supports residential and light commercial power venter installations on gas-operated units

Compatibility

Designed for use with power venters on gas-operated units controlled by a remote thermostat or on/off switch in 750mV millivolt systems. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional familiar with millivolt control systems and local mechanical codes. Shut off the gas supply and disconnect any power to the appliance before beginning service. Verify that the existing pilot generator output meets the 750mV requirement before wiring the control kit into the circuit. Follow all applicable local codes and the equipment manufacturer's instructions for power venter integration.
