Side Wall Protection

BFC36 Balance Flue Heat-Circulating Fireplace

Hearth Installation

Adjacent combustible side walls that are within mini- mum dimensions shown in Figure 24 of the fireplace opening must be protected with CFM Corporation Wall Shield Model SP40 or a specifically built wall shield described in Figure 18.

The special wall shield design described in Figure 18 is an alternate method of adding protection to side walls and can be used in place of the SP40 with the same wall clearances specified for the SP40. Rt must =1.85 minimum.

Examples of wall shield insulation:

1.Manville - CERAFORM 126, K=.27, 1/2 inches thick

2.EH2416, K = .458,

1 inch thick required.

A hearth extension is required to protect a combustible floor in front of the fireplace. Refer to Figure 21 for mini- mum dimensions and mounting detail.

Note: Hearth Extension must not cover the air inlet opening of a fireplace.

The hearth extension described in Figure 21 must be a durable non-combustible material with a minimum (total) Rt value of 1.09; refer to Figure 22 for examples. The overall height (above a combustible floor), depth and width must be as indicated, with the extension cen- tered to the fireplace opening.

The top of insulation must be covered with a non-com- bustible decorative covering or a piece of .018” mini- mum sheet metal, to protect hearth extension material.

(Fig. 21)

Secure the hearth extension to the floor to prevent shifting, using trim molding or other similar means at three (3) outer edges. Seal crack between the fireplace hearth and hearth extension with a non-combustible

material. (Figs. 21 and 23)

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.

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.

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.
