New Buck Corporation 94NC installation instructions

Step (b): Calculate R of proposed system. 4” brick of C=1.25, therefore Rbrick = 1/C = 1/1.25 =0.80 1/8” mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431

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

CAUTION

SPECIAL METHODS ARE REQUIRED WHEN PASSING THROUGH A WALL OR CEILING. SEE INSTRUCTIONS AND BUILDING CODES. “DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.”

DETERMINING CHIMNEY LOCATION

A.CEILINGEXIT ( Using 8” inch Diameter Residential Single Wall (minimum 24-ga.) Black Chimney Connector and any listed 2100 UL 103 HT type Chimney System ). (See Page 14).

1. Suspend a plumb bob from ceiling above unit so that weight is hanging in center of flue exit. (A small weight on a string will serve as a plumb bob). Mark ceiling where string is suspended to locate center of chimney.

2.After locating center of hole, install ceiling support box, chimney flashing and rain cap per chimney manufacturer’s instructions.

Now connect stove and ceiling support box using #24 ga. minimum blue or black steel connector pipe (DO NOT USE GALVANIZED PIPE). Connect each section so crimped end faces downward, and secure each section to each other using at least three (3) sheet metal screws or rivets. Also use three (3) sheet metal screws to fasten pipe to collar on heater. (See Figure 10. Page 15).
