A control component in Signature Command Controlled Direct and B-Vent Gas Fireplaces and Inserts can prevent the units from lighting, even though gas continues to flow. No fires have been reported so far.

Hearth dealers and distributors sold the recalled units nationwide between October 2011 and October 2012 for between $1,030 and $8,160.

If you own a recalled unit, stop using it and turn off the fireplace using the master control switch on the command center. Consumers should then contact Monessen Hearth Systems Company to arrange a free repair.
