GENERAL INSTALLATION PROCEDURE

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

Install liner, if required, for your chosen installation.

Attach metal warning plate to the back of the fireplace with screws or nails.

Set appliance on the hearth (See Hearth Requirements page 5 and Support Kit information on page 16.)

Complete the vent connection required for your instal- lation type.

Relocate plate for Outside Air. (Required for Mobile Home Installation) page 13; Assemble Panel Set and Cast Trim Set or the Basic Panel & Trim Set and install as one piece. See page 14.

Position unit into fireplace leaving width enough for fiber- glass batting to be inserted around face seal.

Work unit securely into the fireplace using sheet metal shims if leveling bolts are needed. See Figure 12B on page 12.

Remove all labels from glass prior to building first fire.

Ensure that plated surfaces are cleaned prior to build- ing first fire. See page 20.

Read Operation Instructions found on pages 18 and 19.

if installing this model to a masonry chimney, always be sure the chimney is in good condition and that it meets the minimum standards of the national fire protection association (NFPA) standard 211. A FACTORY BUILT CHIMNEY MUST BE 6 inch (152mm) UL103 HT and ULC S629.

this appliance is made with a 6 inch (152mm) diam- eter chimney connector as the flue collar on the unit. changing the diameter of the chimney can affect draft and cause poor perfor- mance. it is not recommended to use offsets or elbows at altitudes above 4000 feet above sea level or when there are other factors that affect flue draft. See page 5.

CAUTION: tHIS APPLIANCE IS HOT WHILE IN OPERA-

TION AND MAY REMAIN SO UP TO 40 MINUTES OR LONGER AFTER THERE IS NO FUEL IN THE FIREBOX. IF THIS APPLIANCE IS IN A HIGH TRAFFIC AREA OR CHILDREN MAY BE NEAR, IT IS RECOMMENDED THAT YOU PURCHASE A DECORATIVE BARRIeR TO GO IN FRONT OF THE APPLIANCE.

CALCULATING ALTERNATE FLOOR PROTECTION MATERIAL

Thermal Conductivity: k value

The k value indicates the amount of heat (in BTU’s) that will flow in 1 hour through 1 square foot of a uniform material 1 inch thick for each degree (F) of temperature difference from one side of the material to the other. The LOWER the k factor means less heat is being conducted through the non-combustible material to the combustible material beneath it. The k value of a material must be equal or smaller then the required k value to be accept- able.

(BTU) (inch) (foot2 (hour) (oF)

Thermal Resistance: R value

The R value is a measure of a material’s resisteance to heat transfer. R value is convenient when more than one material is used since you can add the R values together, whereas you can not do this for k value. The HIGHER the R factor means less heat is being conducted through the non-combustible material to the combustible material beneath it. The R value of a material must be equal or larger then the required R value to be accept- able.

Converting k to R:

Divide 1 by k and multiply the results times the thickness in inch- es of the material.

R = 1/k x inches of thickness

Converting R to k:

Divide the inches of thickness by R. k = inches of thickness/R

Calculations:

Example: Floor protection requires k value of 0.84 and 3/4 inch thick.

Alternative material has a k value of 0.6 and is 3/4 inch thick.

Divide 0.6 by .75 = k value of 0.80. This k value is smaller than 0.84 and therefore is acceptable.
