To determine the best heating source, look at the density of various wood types (Density is the weight for a given size). The higher the density, the more potential heat output. A standard cord has a volume of 128 cubic feet. This figure also includes the air space between and around the wood. The actual volume in a standard cord is between 60 and 100 cubic feet; depending on how tightly the wood is packed.

Assuming that you are comparing two standard cords of different species but the same volume and moisture content, the denser species will provide more BTU’s. The table of wood species/ densities reveals more helpful guidelines.

STARTING A FIRE

1.To start a fire in a the fireplace properly, first check the operation of the flue damper.

2.To prevent smoking at start-up, close any window located near the fireplace when first lighting a fire. The closed windows may be reopened once a chimney draft is drawn in the fireplace.

DAMPER CONTROL

This fireplace is fitted with a manually controlled chimney damper. The chimney damper should be closed when the fireplace is not in use to prevent cold air from entering the home through the chimney system.

The damper is controlled through the use of a control lever located within the firebox opening at the top center just behind the firebox lintel (Figure 2 ).

The control lever snaps into place at the extreme range of motion, up and back in the closed position. When pulled forward and down, the damper is open.

The appliance flue damper must always remain open when operating.

2.The grate in the firebox should be centered on or over the bottom hearth so your fire can breath properly. Crumble and twist plenty of newspapers UNDER the grate and criss-cross some small dry kindling sticks on top of the paper or on the bottom of the grate.

3.Build a pyramid of three split logs (split will start much faster). Arrange the uneven wood to provide plenty of air space between.

4.Now, light the paper at both sides of the firebox.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

5.Close the screens to prevent the escape of sparks and embers.

6.Close the damper only when your fire is completely out and ashes are cold. Keep closed when fireplace is not in use to prevent unneces- sary loss of heated or cooled air.

SCREEN PANELS

The screen panels must be closed when the fireplace is operated with the glass doors open. However, the screen panels may be left open when the fireplace is operated with the doors closed.

GLASS DOOR SAFETY PRECAUTIONS

FirePlusTM systems include a twin-pane, full en- closure, ceramic door with conventional screen panels. The door and screen panels can be opened for easy refueling. While the fireplace may be operated with the glass doors fully open, it is recommended that the doors be fully closed during operation for best performance. When opening the doors to refuel, a slight spillage should be expected. This should be considered normal. Open doors slowly, otherwise an increase in smoke spillage could occur.

WARNING: IF THE DOORS ARE LEFT PARTIALLY OPEN, GAS AND FLAMES MAY BE DRAWN OUT OF THE OPENING, CREATING RISK OF BOTH FIRE AND SMOKE.

CAUTION: YOUR FIREPLACE IS EQUIPPED WITH CERAMIC GLASS DOORS. EXERCISE CAUTION WHEN OPENING AND CLOSING THESE DOORS AS CERAMIC GLASS IS EASILY BROKEN BY A MECHANICAL IMPACT.
