Positioning the Hearth Extension
STEP 18 - Installing the Glass Doors.
If desired, or required by local building codes, install
the glass doors using the instructions supplied with
the particular set of doors you have chosen.
STEP 19 - Positioning the Hearth Extension.
Position and secure the hearth extension over the
protective metal strips that have been placed partially
under the firebox front. These strips should be pro-
truding approximately two inches from under the fire-
place front. Seal the crack between the hearth
extension and fireplace with a non-combustible
sealant.
STEP 20 - Applying Finishing Materials on the
Hearth Extension.
Apply the non-combustible finishing material of your
choice to the hearth extension.
Do not install com-
bustible materials over the black face of the fire-
place. This poses a safety hazard and may start
a fire.
You may only use non-combustible material
over the black face of the fireplace. Refer to Figure 7
for combustible material information.

STEP 17 - Provisions for a Gas Log Set or Gas Log
Lighter.
Knockouts are provided on both sides of the fireplace
for the connection of a certified gas log lighter or a dec-
orative gas appliance with a maximum input of 100,000
BTU/hr incorporating an automatic gas shutoff device
and complying with the Standard for Decorative Gas
Appliances for Installation in Vented Fireplaces, ANSI
Z21.60. The decorative gas appliance should be
installed in accordance with the National Fuel Gas
Code, ANSI Z223.1. The side refractories are designed
to allow 1/2” iron pipe to pass through. Use a non-com-
bustible sealant to seal any opening between the gas
pipe and the refractory on the inside. Repack the insu-
lation removed, to seal around the gas pipe where it
exits the side of the fireplace. A minimum 1-1/2” air
clearance must be provided to the 1/2” iron pipe.
