This document provides installation instructions for the FBK-250 Blower Kit with Cord Set, designed for use with gas fireplaces. It emphasizes safety precautions, including turning off gas and electrical power before installation, and ensuring proper containment of excess wiring to prevent contact with moving or hot objects. The kit is tested and safe when installed according to these instructions, but users are advised to consult their fireplace's Owner's Installation Manual for supplemental information.

Function Description:

The FBK-250 Blower Kit is an aftermarket accessory designed to improve the heating efficiency of gas fireplaces by circulating air. It includes a fan, a thermodisc/heat sensor, a variable speed control, and a cord set. The system works by drawing in room air from the bottom vent space, circulating it around the hot firebox, and then expelling heated air back into the room through the top vent. The thermodisc/heat sensor automatically activates the blower when the fireplace reaches approximately 120°F and turns it off when the temperature drops below 90°F, ensuring efficient operation without manual intervention. The variable speed control allows users to adjust the fan's speed.

Important Technical Specifications:

Power: Operates on 120V/60Hz power.
Activation Temperature: Thermodisc/Heat Sensor activates at approximately 120°F.
Deactivation Temperature: Thermodisc/Heat Sensor deactivates below 90°F.
Components:
- Fan: 1
- Thermodisc / Heat Sensor: 1
- Variable Speed Control: 1
- Cord Set: 1
- Wire Nut: 2
- Mounting Bracket for Fan: 1
- Dampening Pad, Velcro Strip: 2
- Crimp Butt Connector for Wire: 1
- Face Plate for Wall: 1
- Installation Instructions (Downloadable): 1

Usage Features:

Automatic Operation: The thermodisc/heat sensor ensures the blower turns on and off automatically based on fireplace temperature, providing hands-free operation.
Variable Speed Control: Users can adjust the fan's speed using the variable speed control dial. The control must be in the "ON" position for the blower to operate. Turning the dial left will click it off, and turning it right will reduce speed.
Flexible Installation Options:
- Under Firebox Installation: The variable speed control can be placed on the floor of the lower vent space near the front.
- Wall Mounted Variable Speed Control Option: For fireplaces with an existing wall switch dedicated to the 120V power supply in the vent space, the variable speed control can replace this switch. This involves cutting and crimping wires to integrate the control into the existing electrical setup, and securing it with a face plate.
Easy Fan Mounting: The fan assembly slides into the bottom vent space, with mounting tabs fitting into notches in the mounting bracket. Velcro strips on the dampening pads help secure the fan and reduce vibration.
Clear Airflow Direction: The fan's rectangular air exit port should face upwards to ensure proper heated air circulation.

Maintenance Features:

Pre-Installation Cleaning: Before installing the blower kit, it is recommended to clean the fireplace's vent space to remove drywall dust or other fragments. This prevents potential bearing or motor damage, which is not covered by the warranty.
Damage Inspection: Users are instructed to check the contents of the carton upon receipt and not to install a damaged blower kit.
Proper Grounding: The installation instructions emphasize the importance of proper electrical grounding in accordance with local codes and national electrical codes (CSA C22.1 in Canada, ANSI Z223.1-1988 and ANSI/NFPA 70-1987 in the USA).
Wire Management: Excess wire from the cord set must be contained to prevent contact with moving or hot objects, which is crucial for safety and longevity of the device.

The manual provides detailed, step-by-step instructions with accompanying diagrams to guide users through the installation process, including connecting wires, positioning components, and securing the blower. It also includes contact information for My Fireplace Blower for support.
