Laboratories, Inc. to ANSI Z21.50-1986 as a vented

decorative gas appliance.

Installation must conform to local codes. In theabsence of local codes installation must conformwith the current National Fuel Gas Code, ANSI

Z223.1. Theappliance,when installed,must beelectricallygrounded inaccordance withlocalcodes,with the National ElectricalCode, ANSIINFPANo.70-1984.

Note: Installationandrepairshouldbe donebyaqualifiedserviceperson.Theapplianceshouldbeinspectedannuallybya professionalserviceper-son.Morefrequentinspectionslc/eaningsmayberequireddw toexcessive/intfromcarpeting,bed-dingmaterial,etc.It is imperativethatthecontrolcompartment,burnersandcirculatingairpassagewaysof theappliancebekeptclean.

Provide for adequate ventilation.

~

Provide adequate clearances around air openings

and adequate accessibility dearance for serviceand proper operation. Never obstruct the frontopening of the fireplace.

Minimumclearances to combustibles are:

Sides 112', Floor 0', Back 112', Ceiling 41 112',Sidewall O', Vent Surfaces 1'.

Minimum inlet gas pressure is 4.5 inches watercolumn for natural gas and 11 inches water columnpropane for the purpose of input adjustment.

Maximum inlet gas supply pressure is 7.0 incheswater column fornatural gas and 13.0 inches watercolumn for propane.

Input is 18,000 aTUMR

A 1/8' N.P.T. plugged tapping is provided on thegas control along side of the outlet to the mainburner for a test gage connection.

This apptiance must oot be connected to a chimney

flue servicing a solid fuel burning appliance.

The appliance must be isolated from the gas supply

piping system by dosing its individual manual shut-

off valve during any pressure testing of the gas

supply piping system altest pressures equal to or

more than 112 psig.

INTRODUCTION

The GHC-SOOOis a heat circulating system that

utilizing a miUivok gas control valve and a piezo

ignition system. Glass doors, trim kits and a forced

air fan assembly are optional equipment.

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. T 0 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 specialflame enhancement rod located between the lower

logs and a mineral fiber llame enhancement strip

across from the (lower) burner parts. These devices

colorize the gas flame and produce the "embereffect".

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.

HIGHELEVATIONDERATING

Wheninstallingthesefireplacesabove4,000feellevel, n is recommended that the fireplace bumerbe

derated by changing the existing orifice to a smaller

one. Order and install appropriate high altnude

ACCESSORIESOptionalFanKIt

If the optional Ian kit, Model FAK-1500 is to beinstalled on the GHC-SOOONor GHC-SOOOLgas

fireplace,refertotheinstallaiton instrudions packed

wnh the fan assembly. The GHC-5000NandGHC-SOOOLgas fireplacehas beenprewiredat 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 instaUed later.

HorizontalTrimInstallation

There are three optional horizontal trim kits, Models

35HTK-SPS, HTK-PB and HTK-AB and two 0p-tional vertical trim kits, Models VTK-ABR and VTK-

GOEavailablefor usew~hthe GHC-SOOOgasfireplace.Referto thespecificinstallationinstruc-tionspackedwnh eachtrimkit lor theirproperusage.

OptionalGlassDoors

Several models of optional glass doors are avail-

able for installation on these gas fireplaces. Use

glass door Models 35G-PB, 33BF-AB, 33GOD-AS,33GBF-PB, 33GBF-SPB, 33GBFT-SPB, 33GBF-

ABR and 35GT-SPS wnh Model GHC-SOOON,L.

COLDCLIMATEINSULATION

If you live in a cold climate, seal all cracks around

your fireplace with non-combustible material andwherever cold air could enter the room. It is espe-

cially importantto insulate outside chase cav~ybetween studs and under floor on which rests, if

floor is above ground level.

Surround material must be caulked where n meets

the black metal facing of the fireplace to avoid airintrusion. Use non-combustible caulking material

onlyonfireplacefacingtoseal.

Do nol place insulation materials in the 1"gas vent

system clearance space.
