9.2 Factory Built Fireplaces
The following information applies to Factory Built (metal) Wood-Burning Fireplace installations
:
Trim panels must not seal ventilation openings in the fireplace. Any parts that are removed must be saved and reinstalled if the insert
is ever removed. If the factory-built fireplace has no gas access hole(s) provided, an access hole of 1 1/2” (38.1 mm) or less may be
drilled through the lower sides or bottom of the firebox in a proper workmanship-like manner. This access hole must be plugged with
noncombustible insulation after the gas supply line has been installed.
The damper (A) and grate with logset (B) must be removed or fully blocked open.
The smoke shelf (C), internal baffles (D), screen ( E), masonry lining or refractory (G and I), and metal or glass doors (F) may be
removed.
The fireplace must be permanently marked to indicate that it has been altered and is no longer suitable for burning any fuel unless the
removed parts are reinstalled (See
Figure 9.0.02
). Cutting out of any metal parts is prohibited, except the metal floor (J) as specified.
The insulation (H), and any structured rigid frame member must not be removed or altered (side and top of door frame, side and top of
the face of fireplace, metal sides, etc.).
The metal floor of the firebox may be removed only if the following is strictly adhered to.
The metal floor (J) may be removed to allow additional room for installation of the insert as long as it does not compromise the
structural integrity of the existing fireplace. If the floor is removed the insert must be placed directly on the metal base of the metal
fireplace.
Under no circumstance can it be placed directly on a combustible material
.
