Why Choose the Buck Stove Bay Series Model 91 Catalytic Stove?

Catalytic combustion delivers 1.2 g/hr emissions and longest burn times. The three-cell ceramic catalytic combustor ignites smoke at 700 to 900 degrees Fahrenheit, burning off particulates that would otherwise leave the chimney. Result: higher efficiency, lower emissions, and the longest sustainable low-burn cycles in the Buck Stove lineup, appropriate for overnight heating without reloading.

Heats up to 3,200 square feet, the largest Buck Stove wood stove. EPA tested heat output from 10,400 to 62,745 BTU per hour. The 4.4 cubic foot firebox accepts logs up to 22 inches in front-to-back or side-to-side orientation, supporting extended burn times on a single load. The largest heating envelope in the Buck Stove wood-burning lineup we carry.

Factory-installed variable-speed blower with automatic thermostat. The Model 91 ships with a factory-installed blower, rheostat speed control, and Automatic/Off/Manual switch. In Automatic mode, the internal thermostat activates the blower when the stove reaches operating temperature. The blower distributes heat to adjacent rooms through open architecture or doorways.

Installs as masonry fireplace insert or freestanding stove. Fits an existing masonry fireplace with minimum interior dimensions of 31-3/4 inches wide by 23-1/2 inches high by 15-1/2 inches deep using fireplace kit PA FP91. Alternatively installs freestanding with leg kit FA FS9151 or pedestal kit FA P4150B. The same stove serves both configurations.

The Buck Stove Model 91 catalytic heats 1,800 to 3,200 square feet, the largest heating range in the Buck Stove wood-burning lineup. Tested EPA output ranges from 10,400 to 62,745 BTU per hour. The 4.4 cubic foot firebox accepts logs up to 22 inches. Actual heated area depends on home insulation, ceiling height, layout, and climate zone.

Is the Model 91 catalytic?

Yes. The Model 91 uses a three-cell ceramic catalytic combustor (2 inch by 3-1/2 inch by 6 inch by 25 cells per cell) supplied by Applied Ceramics of Atlanta, Georgia. The catalyst ignites smoke at 700 to 900 degrees Fahrenheit, delivering 1.2 g/hr emissions and 79.5 percent HHV efficiency. An integrated catalyst monitor probe lets you verify operating temperature.

How long does the catalytic combustor last?

Catalytic combustors typically last 10,000 to 12,000 hours of operation. The Model 91 manual specifies visual inspection of the combustor at least three times per heating season. Signs of catalyst end-of-life include loss of heating efficiency, increased smoke, and inability to maintain temperatures above 1,000 degrees Fahrenheit. Replacement combustors are ordered from Applied Ceramics directly.

Does the Model 91 come with a blower?

Yes. The Model 91 ships with a factory-installed variable-speed blower as standard equipment.
