Answers to common questions
Does the Astound Built-In need a vent, a chimney or a gas line?
No. It is an electric fireplace and needs no venting, chimney or gas — only power. It must be hard-wired by a qualified electrician to a dedicated, grounded 15 A circuit, at 120 V or at 240 V; there is no plug-in option.
What is the difference between wiring it at 120 V and 240 V?
Heat. Wired at 120 V the heater runs at 1,500 W, about 5,000 BTU/hr; wired at 240 V it runs at 3,000 W, about 10,000 BTU/hr. The flames and lighting are the same either way, and they run with the heater off.
How is it framed and finished?
Frame a non-load-bearing opening 50-3/4" wide, 26-1/4" high and 13" deep; two people lift the fireplace in and screw its brackets to the framing. Finishing material — combustible or not — butts against the fireplace's finishing flange for a trim-less look, or the included 2" trim covers the cut edge of materials 1/8" to 1-1/2" thick. It is single-sided and cannot be hung on the wall.
Can I put a mantel above it?
Yes. Clearance to combustibles is 0" at the top when the fireplace is recessed, and a mantel needs 3-9/16" above the top of the fireplace. Use a heat-resistant paint or lacquer on the mantel, and keep furniture and curtains 36" from the fireplace.
Where can it be installed?
Indoors, in a framed wall, including bedrooms; it also meets HUD standards for manufactured homes. It is not suitable for a bathroom or for outdoor use, and it is designed to run between 41°F and 95°F.
