Cleaning and Maintenance
Continued
Refractory
The brick refractory on the interior of your fireplace (sides, back and bottom) is manu- factured with a high quality cement mixture and reinforced with a wire mesh.
In a new fireplace or one with new refractory, allow refractory to cure for 24 hours. When building a fire, build a small one for the first 3 or 4 fires. The refractory is subjected to expansion and contraction from the heating and cooling of firebox during operation. It is acceptable to operate the fireplace with cracks of 1/64" wide.
If a crack should develop that is larger than the hairline crack described, take the following corrective measures:
1.Patch crack with a refractory patching cement available at fireplace shops or hardware stores. The refractory must still be in one piece to patch.
2.Replace refractory panel (see fireplace owner’s manual). DO NOT continue to use your fireplace if your refractory has a crack that exceeds 1/64".
Refractories are available through your ser- vice dealer.
Grate
If grate deteriorates or is distorted, replace with DESA Heating, LLC grate designed for your fireplace (see fireplace owner’s manual).
Glass Doors
Clean glass with any commercial glass cleaner or soap and water. Do not use any abrasive material to clean glass. Do not clean glass with cool water if glass is still hot from use. Let doors dry completely before bulding the next fire.
Troubleshooting
Smoke
This fireplace has been designed to operate without smoke spillage into the room when installed and operated properly. In the event a smoking problem does occur, check for one of the following conditions:
1.Outside environmental conditions ad- versely affecting draft.
2.Lack of ventilation due to a tightly insu- lated house could prevent the fireplace from drawing properly. If this happens, open a window a small amount while operating fireplace.
3.Other appliances competing for available air in a tightly sealed home. These could be heating appliances, kitchen exhaust fans and bathroom exhaust fans.
4.Relationship of your house to hills, trees and nearby taller buildings can affect wind conditions which can have a direct effect on your fireplace operation.
5, Chimney termination not installed to proper height.
6.Blockage of flue or termination cap.
7.Flue and termination caked with creosote buildup.
8.Grate too close to front of fireplace, not positioned behind smoke shelf. Position grate in designated area on brackets.
9.Damper not in fully opened position.
10.Outside air damper not in opened posi- tion.
11.Operating fireplace with partially opened doors.
12.Additional chimney pipe(s) may be neces- sary under certain conditions. (Additional chimney pipe available as accessory item.)
IMPORTANT: For
Cold Air Drafts
In cold areas you must take special precau- tions and follow COLD CLIMATE installation instructions in your owner’s manual.
If cold air drafts are present when your fire- place is not in operation check the following:
1.Air coming out of fireplace opening. Close damper.
2.Air near sides of firebox interior. Close outside combustion air damper.
3.Air coming in around sides of fireplace, between fireplace and wall. Make sure fireplace frame has been caulked to en- closure of frame.
