MINIMUM CLEARANCE TO COMBUSTIBLE CONSTRUCTION FROM FIREPLACE AND VENT SURFACES:
It is not necessary to install a hearth extension with this fireplace sys- tem. Objects placed in front of the fireplace should be kept a minimum of 48" away from the front face.
Combustible framing:
Sides, back, and bottom of the unit Top
0" to stand-offs if using optional clean face surround
0" to
3 1/2" to
6 1/2" if using optional clean face surround
When roughing in the fi replace, raise the fireplace to accommodate for the thickness of the fi nished fl oor materials, i.e. tile, carpeting, hard wood, which if not planned for will interfere with the opening of the lower access door and the installation of many decorative flashing accessories.
Note: In order to avoid the possibility of exposed insulation or vapor barrier coming in contact with the fi replace body, it is recommended that the walls of the fi replace enclosure be “fi nished” (ie: drywall/ sheetrock), as you would fi nish any other outside wall of a home. This will ensure that clearance to combustibles is maintained within
Combustible fi replace fi nishing: |
|
Sides, bottom and top | 0" to fi replace edge |
Enclosure top | 8 1/4" to top of fi replace |
Recessed depth | 17 1/4" |
Sides and bottom of the vent pipe | 1" |
Top of vent pipe | 2" |
Ceiling | 72" from bottom of unit |
HORIZONTAL VENT SECTIONS: - A minimum clearance of 1" at the bottom and sides of the vent and 2" at the top on all horizontal runs to combustibles is required. Use fi restop spacer
VERTICAL VENT SECTIONS: - A minimum of 1" all around the vent pipe on all vertical runs to combustibles is required except for clearances in
fireplace enclosures*. See "MINIMUM ENCLOSURE CLEARANCES" section. Use fi restop spacer
* Vertical vent sections in fi replace enclosures require a minimum of 1 1/2" all around the vent pipe.

INSTALLING STANDOFFS
Both the BGD36CF(G) and BGD42CF are supplied with two standoffs. For convenience, the standoffs have been shipped fl at and located on the top at the front. Before framing ensure the standoffs are bent up and screwed into place ensuring a height of 4.5".

It is best to frame your fireplace after it is positioned and the vent sys- tem is installed. Use 2x4's and frame to local building codes.
