WARNING: Hearth extension must be installed in accordance with Figure 23 and must not cover the bottom front opening of the circulating model.

Alternate noncombustible materials may be used pro- viding the (total) thermal resistance (Rt value) of the al- ternate material employed is greater than or equal to R

=1.09 Thermal resistance (R) or thermal conductivity (K), may be obtained from manufacturer of the material. Factors are related by the formula K = 1/R. (Fig. 24)

T = given thickness

R = thermal resistance for a given thickness (T) K = thermal conductivity

Non-combustible material with a lower R value may be used, provided thickness of material is sufficiently greater to maintain an equivalent (total) thermal resis-

tance (Rt).

The fallaway handles are used to open and close the front doors. The fallaway handles may be removed after each use or may be left in place. CAUTION: If the handles are left in place during operation, they may become hot. (Fig. 24)

Adjust door alignment by loosening the phillips head screws which secure the door hinges to the door. Adjusting one hinge while leaving the other tight will serve to rotate the inner edge up or down. Adjusting both hinges at the same time allows the door to adjust side-to-side.

647 BFC specifications

The Vermont Casting 647 BFC, a renowned wood-burning stove, combines timeless design with advanced technology, making it a popular choice among homeowners seeking both efficiency and aesthetics. With its robust construction and classic look, the 647 BFC stands as a statement piece in any living space while delivering a high level of performance.

One of the standout features of the Vermont Casting 647 BFC is its exceptional heating capacity. Designed to warm spaces up to 2,000 square feet, this stove is ideal for residential use, particularly in larger homes or open-concept layouts. The 647 BFC utilizes a large firebox that can hold logs up to 22 inches in length, allowing for extended burn times and less frequent refueling, making it not only convenient but also energy-efficient.

A key technology incorporated into the Vermont Casting 647 BFC is its soapstone lining. This material retains heat longer than traditional steel, ensuring a steady release of warmth even after the fire has died down. This feature contributes to the overall efficiency of the stove, minimizing fuel consumption and promoting a cleaner burn. The stove also features an adjustable air control system, which allows users to fine-tune the burn rate, enhancing efficiency and reducing emissions.

Moreover, the 647 BFC is designed with style and versatility in mind. Its traditional appearance, characterized by a cast iron body and elegant detailing, makes it a fitting addition to both modern and rustic interiors. Available in a variety of finishes, including classic black and vibrant colors, homeowners can find a model that complements their decor.

Safety is a paramount consideration in the design of the Vermont Casting 647 BFC. Equipped with a solid cast iron door and a secure latch, the firebox remains contained, preventing accidental contact with flames. Additionally, the stove features a raised grate system that allows for ash to fall through, keeping the firebox cleaner and reducing maintenance.

In summary, the Vermont Casting 647 BFC combines classic aesthetics with modern technology for an exceptional wood-burning experience. Its impressive heating capabilities, efficient design, and safety features solidify its position as a top choice for anyone looking to enhance their home's warmth and charm. Whether used as a primary heat source or a cozy addition to a living space, the 647 BFC is a testament to quality craftsmanship and thoughtful engineering.
