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 14.

•Complete the vent connection required for your installation type.

•Install optional blower, if purchased, (page 13), then the panel set and finally the trim (page 12).

•Position unit into fireplace leaving width enough for fiberglass batting to be inserted around face seal.

•Work unit securely into the fireplace using sheet metal shims if leveling bolts are needed (page 11).

•Remove all labels from glass prior to building first fire.

•Ensure that plated surfaces are cleaned prior to building first fire (page 18).

•Read Operation Instructions found on pages 15 and 16.

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) UL 103 HT and ULC S629.

this appliance is made with a 6 inch (152mm) diameter chimney connector as the flue collar on the unit. changing the diameter of the chimney can affect draft and cause poor performance. 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 6.

CAUTION: tHIS APPLIANCE IS HOT WHILE IN OPERATION AND MAY REMAIN SO UP TO 40 MINUTES AFTER THERE IS NO FUEL IN THE FIREBOX. IF THIS APPLIANCE IS IN A HIGH TRAFFIC AREA OR CHILDREN MAY BE NEAR, IT IS RECOM- MENDED THAT YOU PURCHASE A DECORATIVE BARRIeR TO GO IN FRONT OF THE APPLIANCE.

ALTERNATE FLOOR PROTECTION WORKSHEET

How to determine if alternate floor protection materials are acceptable:

All floor protection must be non-combustible (i.e., metals, brick, stone, mineral fiber boards, etc.). Any organic materials (i.e., plastics, wood paper products, etc.) are combustible and must not be used. The floor protection specified includes some form of thermal designation such as R-value (thermal resistance) or k-factor (thermal conductivity).

PROCEDURE:

1. Convert specification to R-value:

R-value given - no conversion needed.			K-factor is given with a required thickness (T) in inches:	R =	1	x T
					K x 12
k-factor is given with a required thickness (T) in inches: R =	1	x T	r-factor is given with a required thickness (T) in inches: R =
	k

2.Determine the R-value of the proposed alternate floor protector.

i.Use the formula in step (1) to convert values not expressed as “R”.

ii.For multiple layers, add R-values of each layer to determine overall R-value.

3.If the overall R-value of the system is greater than the R-value of the specified floor protector, the alternate is acceptable.

EXAMPLE: The specified floor protector should be 3/4 inch thick material with a k-factor of 0.84. The proposed alternate is 4” brick with an r-factor of 0.2 over 1/8” mineral board with a k-factor of 0.29.

Step (a): Use formula above to convert specification to R-value.		R =	1	x T	=	1	x	0.75 =		0.893
			k			.84
Step (b): Calculate R of proposed system.	4" brick of R = 0.2, therefore:				1/8" mineral board of k = 0.29, therefore:
	Rbrick = 0.2 x 4 = 0.8				Rmineral board			=	1		x 0.125 = 0.431
									0.9

Rtotal = Rbrick + Rmineral board = 0.8 + 0.431 = 1.231

Step (c): Compare proposed system Rtotal of 1.231 to specified R of 0.893. Since proposed system Rtotal is greater than required, the system is acceptable.

	(ft2)(hr)(oF)	k = Btu(in) = K x 12			Btu(ft)	r = (ft2)(hr)(oF)	1
R =	Btu		ft2(hr)(oF)	K =	ft2(hr)(oF)	(Btu)(in) =	k
