Napoleon Oakville 3 Gas Insert Selection and Installation

Serving the Triangle and surrounding Central North Carolina communities.

A traditional fire with convenient gas operation

If you like the familiar appearance of a wood fire but would rather skip carrying logs and cleaning ash, the Napoleon Oakville 3 is an option worth comparing. Its traditional log display and clean-face design can make an existing fireplace easier to enjoy while providing useful warmth in the room.

You don’t need to choose a model before contacting Chimneys Plus. We can help you compare appearance, heating goals and installation requirements, then select an insert that works with your fireplace.

Contact Chimneys Plus to explore the right insert for your fireplace.

Why consider the Oakville 3?

  • A traditional log fire without wood handling. The Oakville 3 is the simpler log-style choice in the Oakville family. Approved interior panels, faceplates and backing plates let us work with the appearance of your existing hearth. A circulating blower is optional; that choice affects both the space required and the electrical plan.
  • Useful room warmth. A sealed gas insert can make an underused hearth a more practical part of everyday life.
  • Backup warmth when prepared. Gas-fire operation can continue during an outage with the required gas supply and working backup batteries; mains-powered accessories do not operate.
  • Outside air for combustion. The direct-vent system keeps combustion separate from room air and vents exhaust outdoors.

An open fireplace draws air your home has already heated into the fire and sends it up the chimney, carrying much of the fire’s heat with it. A direct-vent gas insert draws combustion air from outdoors instead and delivers useful warmth into the room.

An insert inside your existing fireplace

This appliance is installed inside an eligible existing wood-burning masonry or prefabricated fireplace. It does not replace the entire fireplace, and it is not a freestanding unit or a built-in fireplace that can be framed into a new wall on its own.

Chimneys Plus checks the fireplace’s condition and construction, usable cavity, tapered walls, gas-line location and protrusion, chimney and venting, hearth, mantel, mantel legs and nearby sidewalls. Front and backing-plate choices also affect the finished appearance and access. Minimum dimensions are a starting point, not a fit guarantee.

Planning electrical work

Electrical requirements depend on the selected configuration. The optional blower requires a properly grounded electrical connection, and the electronic ignition has battery backup for power outages. We’ll confirm the power supply needed for your appliance and controls before ordering. A suitable existing connection may be usable; adding or relocating power can mean additional work and investment. If electrical work is needed, Chimneys Plus coordinates it as part of your fireplace installation, so you do not have to arrange it separately.

Frequently asked questions

What makes the Oakville 3 different from other gas inserts?

The Oakville 3 offers the traditional Oakville log presentation with an optional blower. The X3 adds features such as included circulating air and Night Light illumination, while the 3 Glass offers contemporary glass media. Chimneys Plus can help decide whether those extras matter for your room and the way you use the fireplace.

Will the Oakville 3 fit my fireplace?

It may! Napoleon’s model-specific installation manual lists a minimum fireplace opening of 29 inches wide × 21 inches high × 14⅜ inches deep without the optional blower. With the blower, the manual adds 2¾ inches of depth, making the minimum depth 17⅛ inches. These are cavity requirements, not faceplate dimensions. Fronts, backing plates, risers and other installation details still need to be checked against the exact model and current instructions.

The fireplace must also meet the required hearth and combustible clearances. We check the mantel, mantel legs and sidewalls, gas-line location and protrusion, taper and obstructions, vent routing and condition of the existing fireplace. Chimneys Plus can help determine whether this insert is right for your fireplace and identify any adjustments needed for installation.

What style and control options are available for the Napoleon Oakville 3?

The Oakville 3 uses an approved log set with a choice of compatible interior panels, faceplates and backing plates. It has electronic ignition; we’ll confirm the control package you want rather than assume every Oakville version includes the same remote. Only media and finishing parts approved for the exact appliance can be used.

Is the Napoleon Oakville 3 a real backup heat source when the power goes out?

Yes! With gas available and fresh batteries in its backup holder, the electronic-ignition Oakville 3 can keep providing flame and room warmth during a power outage. The optional blower will not run without household electricity. We’ll show you how the selected controls and battery backup work. It is a source of supplemental room warmth, not a guarantee of whole-home heating.

Does the Napoleon Oakville 3 need electricity, and can Chimneys Plus handle that work?

Electrical requirements depend on the selected configuration. The optional blower requires a properly grounded electrical connection, and the electronic ignition has battery backup for power outages. We’ll confirm the power supply needed for your appliance and controls before ordering. A suitable existing connection may be usable; adding or relocating power can mean additional work and investment. If electrical work is needed, Chimneys Plus coordinates it as part of your fireplace installation, so you do not have to arrange it separately.

Can Chimneys Plus install a gas line for the Napoleon Oakville 3 if my fireplace doesn’t have one?

Yes! Chimneys Plus is licensed in North Carolina to install gas piping, and we routinely handle this work as part of gas fireplace appliance installations. We can evaluate your existing gas supply, install the piping needed for your new appliance and handle the required permitting.

Is a permit required in North Carolina to install a Napoleon Oakville 3 gas insert?

Permit requirements depend on the work involved and your local inspection department. Installing a new gas line requires permitting. Replacing the fireplace itself also requires permitting, even when the gas line already exists. For a gas insert installed inside an existing fireplace, we’ll confirm the requirements for your project. Whenever a permit is required, Chimneys Plus handles the permitting for you.

Should I choose gas logs or a gas insert such as the Napoleon Oakville 3?

Vented gas logs are often chosen mainly for ambiance. A sealed direct-vent gas insert is worth considering when you want more useful room heat, greater control and backup warmth. It uses outdoor combustion air and vents exhaust outdoors.

Vent-free gas logs can provide a quick burst of warmth, such as taking the chill off a room in the morning. For longer periods of heating, a sealed direct-vent insert is often the better choice. Vent-free logs produce substantial room heat, but release combustion byproducts and moisture into the home. They are intended for supplemental, intermittent use rather than continuous heating. Chimneys Plus recommends short operating periods, generally a couple of hours at a time, with ventilation that may include cracking a window as required by the appliance instructions and room conditions. An open window does not replace those ventilation requirements.

Do I need to choose an insert such as the Napoleon Oakville 3 before contacting Chimneys Plus?

No! You don’t need to know which brand or model you want before reaching out. Tell us what you’d like to improve about your fireplace, whether that’s warmth, ambiance, convenience or backup heat, and we’ll help you compare suitable options. We can guide you through fit, performance and style so you can choose with confidence.

Does the Napoleon Oakville 3 need regular maintenance?

Yes. Regular professional service helps keep the burner, pilot, glass, controls, venting and any blower working as intended. We can help you plan appropriate maintenance and explain routine battery care. Only approved media and components should be used, and the installed glass and protective barrier must remain in place during operation.

What warranty does Napoleon offer for the Oakville 3?

Napoleon provides a President’s Lifetime Limited Warranty, with coverage and limits that vary by component. It is not lifetime coverage for every part or all service costs. We can help you review the warranty for the exact appliance and explain how a service or warranty request is handled.
