INSTALLATION PREPARATION
Fireplace:
1. Locate furniture and other materials away from the front of the fireplace to allow free access to the fireplace.
2. Cover the hearth and adjacent floor areas with the drop cloths to protect from soiling or marring the surface.
3. Remove the existing fireplace damper plate.
4. Thoroughly clean the fireplace of ashes and soot.
5. Have your existing chimney inspected before inserting this unit. Some chimneys must be relined or replaced before
they are safe to use.
6. Check the chimney and smoke chamber for excessive buildups of creosote or soot. Also, check for obstructions, such
as bird’s nests. If the chimney is excessively dirty, clean it, or have someone clean it professionally BEFORE install-
ing or using the room heater.
7. If the fireplace has an ash dump or outside air provision, these must be sealed off with metal or tightly packed non-
combustible insulation to prevent cold air from entering the fireplace chamber.
Heater:
1. Inspect the unit for any obvious physical damage.
2. Check the primary air draft controls to ensure that they slide freely.
3. Check the operation of the damper control to ensure it will open and close properly.
4. Check the Manual/Automatic Switch to ensure that motor is working. *Place switch in the “MANUAL” position. (Plug
in stove.) You cannot check the motor in the “AUTOMATIC” position, unless a heat gun is used to heat the internal ther-
mostat.
