Technical notes

Use a qualified installer to check fuel, gas pressures, altitude, fireplace fit, mantel projections, hearth and combustible-floor clearances, and approved vent routing. Maintain the safety barrier and sealed glass assembly. Never burn wood in a gas insert.

Photos are manufacturer series illustrations and may show a different size or optional logs, liner, front, surround, mantel and finishing. Installation, gas and electrical work, materials, venting, finishing, delivery, optional accessories and tax are separate.

The insert uses a dedicated vertical liner/termination system; the installation manual governs run lengths and any chimney extension. Do not assume a horizontal wall termination is allowed.
