Superior Model DR-500CMN |
Most of the units here in the Manors have a Model DR-500CMN direct-vented gas fireplace that was manufactured by the Superior Fireplace Company. This model has been discontinued and Superior is now a unit of Lennox Hearth Products. The DR-500CMN Homeowner's Care and Operation Manual is still available here for viewing and download.
Some of the newer Manors units have a Model VCD36RN direct-vented gas fireplace that was manufactured by Desa Heating LLC. Desa filed for bankruptcy in December of 2008 and is no longer in business. However the VCD36RN Owner's Operation and Installation Manual is still available here for viewing and download.
Both of these models are similar in design and operation. The Superior fireplace is rated at 23,000 BTUs per hour input while the Desa has an input rating of 21,000 BTUs per hour (as a reference, the input ratings for the forced air gas furnaces here in the Manors are 75,000 BTUs per hour and up). Even though your fireplace is probably operated using a conventional 110 volt wall switch, both fireplace models use millivolt gas controls, meaning that if the pilot flame is burning, the fireplace burner can be turned on and off even during a power failure (however the optional blower will not be functional). During an extended cold-weather power failure, your gas fireplace should be able to provide enough heat to keep your plumbing from freezing, even without the warm air circulation normally provided by the blower.
Here's some advice on how to keep your gas fireplace working and looking good:
