GALAXY SUPREME FIREPLACES

4.2.1 Clean Face Configuration
The gravity kit is required to be installed with the louverless Clean Face
configuration of the Galaxy.
Instructions for Gravity Kit Installation:
1. Remove the knockouts from the top of the fireplace.
2. Cut the insulation and remove the knockout below the insulation. Assure
that both openings are completely open and you can see all the way down
to the top of the firebox.
3. Remove the rectangular knockouts from the sides of the fireplace.
CAUTION: Both knockouts from the top and bottom must be removed.
Parts Required:
CM2315, CY2304, and CY2305-2. The face part # GY4000-3 can
be installed later on.
Gravity Kit Installation Rules:

Two hot air gravity ducts must be installed.

The two hot air grilles can be installed in the same or in different rooms
from each other. If the grilles are installed at different heights, more heat
will be distributed to the highest one.

Two openings are required at the lower part of the chase for the entry of the circulating air.

Each opening must have an area no less than 80 square inches. The location of the openings is left at the discretion
of the installer.
Tip: Openings can be made on the floor inside the chase (not underneath the fireplace) to bring the circulating air
from a floor below the floor the fireplace is installed in as long as that floor communicates freely with the room in
which the fireplace is installed.
WARNINGS:

The hot air grilles of the Gravity Kit should be at least 68 inches from the floor and the ducting should have a
maximum length of 10 feet (see figure 14).

Make certain that each exit grill has a minimum circulating area 60 square inches.

The hot air ducts should never extend downwards; only horizontally or upwards.

A minimum clearance of 10 inches must be respected from the hot air grilles to any combustible wall, mantle or
ceiling.

The hot air ducts must not be connected to a central heating system.

The hot air ducts must be insulated.

Do not make the chase unnecessarily small. Be sure that the air entry through the chase can easily flow to the entry at
the openings at the lower part on the sides of the fireplace.
4.3 Framing
The fireplace can be placed directly onto or against
normal, combustible construction materials such as
lumber, plywood, millboard, particleboard, drywall and
decorative wood paneling. The fireplace should NOT be
placed directly against, or be in contact with an
insulation material. The framing on the face of the
fireplace must be constructed with nominal 2" x 3" metal
studs (see figure 15). The framing must be nailed or
screwed onto the floor and to the ceiling.
WARNING: DO NOT NAIL OR SCREW FRAMING MEMBERS INTO THE FIREPLACE.
