The safety strips should extend in front and
sides of the fireplace opening 2" (51 mm) . In
the event a wooden support is used to elevate
the fireplace above the floor, a “Z” type safety
strip should be fabricated and used to protect
the front surface of the wood support as well
as the floor beneath the hearth extension (
see
Figures 8, 9, 10, and 11 ). The safety strips
should be tacked down to prevent possible
movement.
Note: The “Z” type safety strip is not supplied.
Step 3. Refer to fireplace drawings and speci-
fications on pages 7 and 8 for framing dimen-
sions and details. False header may be posi-
tioned directly on top of the fireplace spacers
(
see Figures 12, 13 and 14 ).

YOU NOTCH THE HEADER TO FIT AROUND OR
BE INSTALLED LOWER THAN THE SPACERS.
THE HEADER MAY BE IN DIRECT CONTACT
WITH THE TOP SPACERS BUT MAY NOT BE
SUPPORTED BY THEM.
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
The header may rest on the top metal spacers,
but must not be notched to fit around them.
