2. Product Overview
The AC Infinity AIRBLAZE T10 is a universal fireplace blower fan kit designed to enhance heat circulation from your fireplace into your living space. It effectively draws cool air from lower vents, heats it within the fireplace cavity, and then expels the warmed air into the room. This system is compatible with various fireplace brands, including Lennox, Hearth Glo, Majestic, and Rotom, and can serve as a replacement for existing blower units. The kit includes a smart controller with temperature and speed adjustments for optimized performance.

6. Installation Guide
The AIRBLAZE T10 is designed for straightforward installation in fireplaces with an accessible cavity beneath the firebox. Installation typically involves placing the blower unit, routing the sensor probe, and connecting the controller.
6.1. Pre-Installation Check
- Confirm your fireplace has adequate space for the blower unit (refer to specifications for dimensions).
- Ensure a standard electrical outlet is available nearby for the power adapter.
- Gather necessary tools: screwdriver, measuring tape, and potentially a drill if mounting with screws.
6.2. Blower Placement
- Carefully slide the blower unit into the designated compartment beneath your fireplace.
- Position the blower to maximize airflow into the fireplace cavity.
- Secure the blower using the provided mounting hardware. Velcro pads can be used for non-permanent installation, or screws for a more secure fit.
6.3. Sensor Probe Installation
- Route the 12-foot corded sensor probe into the fireplace cavity.
- Place the sensor tip in an area that accurately reflects the temperature of the fireplace, typically near the heat exchanger or where warm air exits. Avoid direct flame contact.
6.4. Controller and Power Connection
- Connect the blower unit cable to the controller.
- Connect the sensor probe to the controller.
- Plug the power adapter into the controller, then into a standard electrical outlet.
- Position the controller in a convenient location. It can be mounted on a wall or placed discreetly near the fireplace.
