Opel Residential Factory Built Fireplace Maintenance Operation Installation PDF Manual
THE COMBUSTION CONTROL SYSTEM
Since the doors are sealed, all combustion air must come through the OPEL2’s draft control. This control has a bimetal coil to allow more air when the unit is cold, and less air when the unit is hot, guarding against overheating. t can be controlled either manually with the lever that is located below the right window frame, or automatically with an optional electric wall thermostat. For the first few days, it is best to operate the fireplace with the manual control fully open (moved to the right as ar as possible). Just control the fire as you would any normal fireplace, using one or two logs at a time for a smaller fire, or more logs for more heat. Once you become familiar with operating the fireplace with the control open, you can start experimenting with lower settings. Remember: when the fireplace is hot, the control will not need as much movement to reduce the fire as when it is cold. The bimetal coil will already have shut the damper part way.
