250-638D
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 oor protection materials are acceptable:
All oor protection must be non-combustible (i.e., metals, brick, stone, mineral ber boards, etc.). Any organic materials (i.e., plastics, wood paper
products, etc.) are combustible and must not be used. The oor protection specied includes some form of thermal designation such as R-value
(thermal resistance) or k-factor (thermal conductivity).
PROCEDURE:
1. Convert specication to R-value:
2. Determine the R-value of the proposed alternate oor 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 specied oor protector, the alternate is acceptable.
EXAMPLE: The specied oor 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 specication to R-value.
Step (b): Calculate R of proposed system.

4" brick of R = 0.2, therefore:
1/8" mineral board of k = 0.29, therefore:

= 0.8 + 0.431 = 1.231
Step (c): Compare proposed system R
total
of 1.231 to specied R of 0.893. Since proposed system R
total
is greater than required, the system is acceptable.

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 replace 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 nally the trim (page 12).
Position unit into replace leaving width enough for berglass batting to be inserted around face seal.
Work unit securely into the replace using sheet metal shims if leveling bolts are needed (page 11).
Remove all labels from glass prior to building rst re.
Ensure that plated surfaces are cleaned prior to building rst re (page 18).
Read Operation Instructions found on pages 15 and 16.
