About this model
Overview
The Oakville is a direct vent gas insert built to sit inside an existing fireplace, drawing combustion air from outside and exhausting through the same lined route. It is listed in three models: the 3 Glass, which burns over a glass media bed, and the X3 and X4, which use traditional log sets.
Ignition is electronic and the appliance is listed for natural gas, with propane available by special order. The face can be completed with a cast iron surround in black or a three-sided black backerplate, or left to the finish of the opening. Vent and liner components are specified with the insert.
Is this right for your home?
An existing fireplace where the look of the fire — glass media or logs — is part of the decision.
Check before ordering
- The height, width and depth of the existing opening, since the model and surround are chosen to suit it.
- Which fire bed you want: the 3 Glass model or the X3 and X4 log models.
- Whether the property is on natural gas, as propane is a special order.
Worth knowing
- The three models differ in the burn display and size, so they are not interchangeable once the opening is finished.
- Surrounds are ordered with the appliance rather than added later.

Installation
The opening decides which of the three models fits and which surround finishes the face. The insert is then installed with a lined direct vent route through the existing chimney.
Brown Chimney can measure the opening, inspect the chimney and confirm the installation before anything is ordered.
Service availability depends on your location.
What to check before installation
What an assessment of this model would cover:
- Measured opening against the dimensions of the 3 Glass, X3 or X4 model.
- Chimney condition and the lined vent route required.
- Gas supply type and the surround needed to finish the face.

Frequently asked questions
What is the difference between the models?
The 3 Glass model burns over a glass media bed, while the X3 and X4 use traditional log sets. They also differ in size, so the opening usually narrows the choice.
Can the face be finished in cast iron?
Yes. A black cast iron surround or a three-sided black backerplate can be ordered with the insert, or the opening can be finished without one.
Which fuel is it supplied for?
Natural gas as listed, with propane available by special order. The configuration is settled when the insert is ordered.
