The fire incorporates under-log burners to provide the most realistic effect, with a unique turndown feature allowing the rear burners to be turned off independently to keep the flame picture alive when running on low. This 22” appliance installs into any standard 16” x 22” back panel and is shrouded with an aluminium high definition stove trim, so it’s a perfect upgrade from your old 16” fire without changing the fireplace. Talk to your dealer for full details. The Ravel 550 is supplied with slide control as standard.
