Always adhere to local building codes when installing a wall
Figure 7 shows a method of passing a connector through a wall. All combustible material in the wall is cut away to provide the required clearance that is three times the pipe diameter. The resulting space must re- main empty. A

Hearths
This appliance must be installed on to hearth that meets the requirements of Part J of the Building Regu- lations 2000 (Combustion Appliances and Fuel Storage Systems). This can be achieved by ensuring that the hearth is constructed and sized in accordance with the guidelines included in section 2 of approved document ‘J’. The size and clearances of the hearth are as fol- lows:
The constructed hearth should be constructed in ac- cordance with the recommendations in document J, and should be of minimum width 840 mm and minimum depth 840 mm (if a free standing hearth b) above) or a minimum projection of 150 mm from the jamb (if a recessed hearth a) above).

Floor Protection for Fireplace Installations
Do not assume your fireplace hearth is completely noncombustible.
Many fireplace hearths do not satisfy the “completely noncombustible” requirement because the brick or concrete in front of the fireplace opening is supported by heavy wood framing as in Figure 8. Because heat passes through brick or concrete readily, it can easily pass through to the wood. As a result, such fireplace hearths can be a fire hazard and are considered a com- bustible floor.
Keep in mind that many raised hearths will extend less than the required clearance from the front of the heater when it is installed. In such cases, sufficient floor protection as described above must be added in front of the hearth to satisfy the minimum floor protector requirement from the front of the stove: 406 mm (16”) from the front. Fireplace hearths must also offer the required protection of 152 mm (6”) on either side.
Optional 76 mm (3”) short legs may be used only on such hearths that meet the width and depth require- ments outlined previously under “floor protection.”
Hearth rugs do not satisfy the requirements for floor protection.
Fireplace installations also have special clearance requirements to the side walls, side decorative trim, and fireplace mantle. Refer to the information on fireplace and mantel trim shields in this section.
