HROIZONTALTRIMINSTALLATION
On the GHC Model, remove the four (4) black
louvers and the two (2) antique brass cover pieces
from the protective container and fasten onto the
face ofthe fireplace. The louver str~ snap onto the
louver pegs wnhoutthe need fortools. T0 assemble
the louver str.,s, tilt the str., on top of the pegs and
snap lower edge to lock in place. The antique brass
cover pieces are mounted over the support bars
directly over and below the fireplace opening. They
also snap into place. Keep the locking dimples on
the bottom side of the covers when installing.
FLAMECOLORIZATIONDEVICES
The burner assembly is equ.,ped with a special
flame enhancement rod located between the lower
logs and a mineral fiber llame enhancement strip
across fromthe (lower) burner parts. These devices
colorize the gas flame and produce the "ember
effect".
In normal operation, these devices will provide
many hours ofsatisfadory performance. Overtime,
the orange color wUldiminish in intensity and it will
be necessary to purchase a replacement rod and/
or mineral fiber flame enhancement device. These
devices are available at nominal charge from your
local distributor/dealer or directly form Superior.

If the optional Ian kit, Model FAK-1500 is to be
installed on the GHC-SOOONor GHC-SOOOLgas
fireplace,refertotheinstallaiton instrudions packed
wnh the fan assembly. The GHC-5000NandGHC-
SOOOLgas fireplacehasbeenprewiredat the fac-
tory to accept the forced air kit at some later time.
The firepalce,must, however,be connected to
main powersupplyattime of installation if the FAK-
1500 forced air kit is to be instaUedlater.
HorizontalTrimInstallation
There are three optional horizontal trim kits, Models
35HTK-SPS, HTK-PB and HTK-AB and two 0p-

COLDCLIMATEINSULATION
If you live in a cold climate, seal all cracks around
your fireplace with non-combustible material and
wherever cold air could enter the room. It is espe-
cially importantto insulateoutsidechase cav~y
between studs and under floor on which rests, if
floor is above ground level.
Surround material must be caulked where nmeets
the black metal facing of the fireplace to avoid air
intrusion. Use non-combustible caulking material
onlyonfireplacefacingtoseal.
Do nol place insulation materials inthe 1"gas vent
system clearance space.
