What is a Gas Fireplace Blower?

A gas fireplace blower is a fan installed inside the firebox or connected via ductwork that pushes heated air from the fireplace into the room. The blower runs on electricity and turns on once the fireplace heats up. The blower improves heat circulation and efficiency by dispersing warm air more evenly throughout the room.

Here are some key features and benefits of fireplace blowers:

• Improves heat output – A blower can increase heat circulation from a gas fireplace by up to 50%. This allows more heat into the living space.
• Spreads warmth faster – The fan action pushes hot air off the fireplace glass and into the room quicker.
• Evens out temperature – The blower diminishes hot and cold spots by distributing warm air around the room.
• Reduces operating costs – By circulating heat better, a blower allows lowering the thermostat which saves energy.
• Runs automatically – The blower has a temperature sensor and turns on/off automatically based on fireplace heat.
• Quiet operation – Blowers create a gentle white noise when running, but are relatively quiet.

Overall, a blower can significantly enhance the functionality and heating effectiveness of an existing gas fireplace.

Can a Blower be Added to Any Gas Fireplace?

Whether or not a gas fireplace can have a blower added depends on the following factors:

• Installation space – There must be enough open space inside the firebox at the back or bottom to mount the blower.
• Electrical access – Wiring will need to be run to the blower location for power. There must be access behind the unit.
• Mounting points – The firebox interior must have suitable mounting points to attach the blower.
• Ducting option – For some units, ducting is required to connect the blower output to the room. There must be accessibility to install ductwork.
• Fireplace construction – Masonry fireplaces have more flexibility. Pre-fabricated fireplaces may not be suitable if space is constrained.
• Consult manufacturer – The appliance manufacturer should be consulted before modifying a gas fireplace.

So the physical construction of the individual gas fireplace unit must be assessed before determining if adding a blower is possible. Consulting a qualified installer is the best way to evaluate your options.

How Much Does it Cost to Add a Blower to a Gas Fireplace?

If at any point the project exceeds your skill level, call in a professional installer. Work done improperly could create safety issues in a gas fireplace.

Adding a Blower at Time of New Fireplace Installation

For new fireplace installations, the ideal time to add a blower system is during the initial installation process. Planning the blower at the time of deployment allows:

• Evaluating the best blower location and configuration options for the fireplace model and design.
• Routing wiring and ductwork (if needed) more efficiently before enclosure.
• Installing mounting points and hardware tailored for the blower.
• Simplified access to the firebox before the surrounding construction is completed.
• Incorporating the electrical load of the blower into the overall home electrical plan.
• Budgeting for the blower as part of the whole project.
• Integration with connected smart home systems can be pre-configured.
• Testing blower operation before finishing construction.

By planning the blower during initial gas fireplace selection and design, the system can be purpose-built for optimal blower function. This can streamline installation compared to retrofitting a blower later on.

Key Installation Steps

The main steps involved in adding a blower to an existing gas fireplace are:

1. Turn off gas supply and shut off electrical power.

2. Remove fireplace backing/facade materials to gain internal access.

3. Determine the optimal mounting location based on blower type, clearance requirements, and access to run wiring.

4. Attach mounting hardware securely to the firebox interior.

5. Install the blower following the manufacturer’s instructions.

6. Route wiring from breaker panel through wall/framing to blower. Connect wires accordingly.

7. Replace/reseal any insulation, vapor barrier, and paneling around the fireplace.

8. Reconnect gas line and test for leaks using a gas sniffer. Verify proper burner operation.

9. Turn on electrical power and test functionality of blower and controls.

10. Reinstall finished facade materials around the fireplace.

Always refer to the manufacturer’s instructions. Have repairs or modifications inspected by your local building department where required.

How Does Fireplace Blower Electrical Wiring Work?

Electrical wiring for gas fireplace blowers must be installed properly for safe and correct operation. Here are some key wiring considerations:

– Power supply – The blower should be wired to its own dedicated 120V circuit with neutral and ground. This avoids overloading other circuits.

– Wire gauge – 12 or 14 gauge electrical wire is normally used, following local codes. Larger CFM blowers (>400 CFM) may need 10 gauge supply wire.

– Wiring location – Wires must be routed through framing into the firebox cavity cleanly, without exposure to heat or sharp edges.

– Wire connections – Wiring should connect to the blower’s electrical leads or wiring harness securely using proper splice connectors.

– Control panel – Some blowers have controls mounted outside the fireplace. These require running an additional low voltage control wire.

– GFCI protection – If accessible, the blower circuit should have ground fault protection. This is not always required by code.

– Communication protocols – Smart blowers may use protocols like AC powerline signaling, wireless, or Bluetooth to enable app control.

Properly installed blower wiring is neatly run, connected securely, uses in-wall rated components, and tested for functionality. Consult an electrician if unsure.
