Installation

The following formula can be used to determine the maximum heater rating per the definition of unconfined space:

BTU/HR = (L1+L2) Ft x (W) Ft x (H) Ft x 1000

Consider two connecting rooms with an open area between,

with the following dimensions:(See Fig. 2, Example)
L1=15-1/2 Ft., L2=12 Ft., W=12 ft., H=8Ft		H (8')
50		H (8')
50	L2 (12')
=52800 BTU/HR	L2 (12')
=52800 BTU/HR
	L1 (15-1/2')	W (12')
	L1 (15-1/2')
If there were a door between the two rooms the calculation

	would be based only on the room with the heater.
	BTU/HR=(15-1/2) x (12) x (8) x 1000

	=29760 BTU/HR

WARNING WARNING WARNING

When installing the appliance directly on carpeting, tile or other combustible material, other than wood flooring, the appliance must be installed on a metal or wood panel extending the full width and depth of the appliance.

If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, Section 5.3, or applicable local codes.

Ensure the minimum clearances shown in FIGURE 3 are maintained for accessibility for purposes of servicing and proper operation. Left and right clearances are determined when facing the front of the heater.

B9945N specifications

The United States Stove B9945N is a premium wood-burning stove designed to provide efficient heating while adding a classic aesthetic to any home. This model is known for its robust construction and innovative features, making it an ideal choice for homeowners looking for both functionality and style.

One of the standout characteristics of the B9945N is its spacious firebox. It can accommodate logs up to 22 inches in length, allowing for longer burn times and reducing the frequency of reloading. This feature not only enhances convenience but also helps in maintaining consistent heat output during colder months. The firebox is lined with fire brick, which helps in optimizing the combustion process by retaining and radiating heat more effectively.

The B9945N also features an advanced air wash system that keeps the glass door clean. By directing air over the surface of the glass, this system helps to prevent soot and creosote buildup, ensuring a clear view of the fire and an aesthetically pleasing appearance. This is particularly valuable for users who appreciate the ambiance of a visible flame without the hassle of constant maintenance.

Moreover, the stove utilizes a secondary burn technology that enhances its efficiency. This feature ensures that more of the smoke produced during combustion is burned off, resulting in cleaner emissions and a greener footprint. Not only does this make the B9945N eco-friendly, but it also maximizes heat output from the wood fuel, making every log burned contribute more effectively to warming your space.

The stove's construction is a combination of heavy-duty steel and cast iron, providing durability and long-lasting performance. The elegant design, coupled with a matte black finish, allows it to fit seamlessly into various décor styles, whether rustic or modern. Additionally, the unit is equipped with adjustable air controls, giving users the flexibility to regulate the burn rate and, consequently, the heat output, catering to individual comfort needs.

In summary, the United States Stove B9945N combines efficiency, aesthetic appeal, and innovative technology. From its spacious firebox to its advanced air wash and secondary burn systems, this wood-burning stove is engineered for performance and designed to enhance the warmth and beauty of your home. With the B9945N, homeowners can enjoy a captivating fire while benefiting from efficient and eco-friendly heating.
