Combustible mantle clearance can vary according to the | CORNER | |
mantle depth.Use the graph to help evaluate the clearance | POST | |
needed. Curtains, above the fireplace, must not be posi- |
| |
tioned lower than the 2" distance required for the 2" com- | NAILING | |
bustible mantle. These same requirements apply to any | TAB | |
combustibles protruding on either side of the fireplace. |

1)Attach the nailing tabs to the corner
posts using the 2 sheet metal screws | FIGURE 42 |
|
supplied. Secure through the centre |
| |
of the top and bottom slots in the nail- |
|
|
ing tab and then through the existing |
|
|
holes in the corner posts. | NAILING | |
If there are no existing holes, follow | TAB | |
these instructions: |
|
|
Position the nailing tab so that the front |
|
|
face is offset with the front edge of the |
|
|
corner post (approx. ½"). Centre the |
|
|
nailing tab vertically on the corner |
|
|
post. |

Drill through the centre of the top and bottom slots in the nailing tab. Secure using the two sheet metal screws supplied. This allows the nailing tab to slide back and forth for desired fram- ing. Figure 43 b.
2)To determine the final location of the nailing tab
you must first determine the thickness of your finishing material (i.e. drywall). This will determine the dimension from the front edge of the corner post to the nailing tab. Once the nailing tab is in the desired location, drill through the centre hole of the nailing tab. Secure with a sheet metal screw*. Figure 43 c.
*Additional set screws may be installed.
