Archgard: Harmonia 22 - Millivolt Ignition

A small clean-face gas insert for the smallest fireplace openings, no electricity needed to run.

Quick Facts

• Efficiency: 63.13% to 66.14% (P.4 fireplace efficiency, by valve).
• Fuel: Natural gas or propane.
• Controls: Pilot-lit valve (no electronic ignition); works with third-party remotes.
• Fan: Optional

Who It’s For

An old wood fireplace is drafty, dirty, and sends most of its heat up the chimney. You need a gas insert that turns it into a clean, efficient fire. The Archgard Harmonia 22 pilot-lit insert is for the existing wood-burning fireplace it fits.

What Makes It Special

Archgard built the Harmonia 22 to transform the smallest of openings, with a panoramic wall-to-wall flame over a high-definition log set behind shatter-resistant ceramic glass.

It is both a radiant and a convection heater; add the optional six-speed heat distribution fan for more air movement. Quebec City brick panels in gray or red, or reflective ceramic glass, finish the firebox. Archgard backs it with its Worry-Free Elite Limited Lifetime warranty.

Possible Downsides

• The remote and fan are extras. It is compatible with third-party remotes.
• A surround is chosen separately. Pick a surround kit to finish the opening.

If you want a small gas insert with simple pilot-lit controls, the Harmonia 22 is the right decision. The fireplace you stopped using becomes the place you gather.

Choose a surround, decorative trim, plinth, and panel set; add the six-speed fan.
