• A gas log lighter access can be provided for in the Magnum-See-Thru and Magnum standard models.
IMPORTANT NOTE: This is an access only and should be used only to bring the gas line through.
Do not make a direct connection to the fireplace box or a fracture of the gas line may occur. A log
grate must be used to prevent any direct contact of firewood with the lighter. Refer to log-lighter
manufacturer’s instructions and to your local building jurisdiction before installing.
• Place at least 12” of fiberglass insulation, with the paper removed, on top of the slab.
• You are ready for the face brick. A ¼” – ½” expansion joint along the faceplate is necessary along
both sides and over the top supported by the lintel iron. Note: If this expansion area is not left
between the unit and the brick, face brick cracking will occur. The steel fireplace must not, at any
point, touch any of the block or brick work. When ever it must be sealed, use ½” insulation to form an
expansion joint. CAUTION: The facing material must be a masonry product over the entire front of
the unit starting at the concrete slab and going all the way to the ceiling.
• A sleeve has been provided on the damper control system to allow expansion of the unit. Make sure
that there is no binding on this system. Note: If a mantelpiece is to be used, provide for it at this time.
We recommend using a non-combustible mantle.
• When laying up face brick on the sides and back, allow at least 4” of space to be filled with loose
fiberglass insulation. If the face brick is being used on the outside of the building allow 6” of area to
be insulated. Make sure that this insulation surrounds the bottom slab below the frostline, thus
preventing any cold air conduction through the hearth and lower grill area. SEE FIGURE ________
Note: If installing adjacent to combustible materials, leave at least 6" of open space between block
and combustible surface. Fill this area with fiberglass insulation.
• As you progress to the ceiling, install the upper grill. This grill must be installed no closer than 17”
from ceiling and must be positioned immediately under the slab to prevent a heat trap. Allow the grill
to be removable for future access. Note:: Make sure that the face brick and face of the top slab are
sealed together with mortar to prevent any heat from escaping. A double soldier course can also be
constructed provided that the minimum of 300 sq. inches of opening are allowed to release the heat.
CAUTION: This provision is intended for connection to a decorative gas appliance incorporating an automatic shut-
off device and complying with the standard for decorative gas appliances for installation in vented fireplaces.
When using the decorative appliance, the fireplace damper must be set in the fully open position.
ELECTRICIAN’S NOTE: Now is a good time to see that all electrical is serviceable and operating properly.
