Inplanningtheinstallationfortherebox,itisnecessarytodetermine
wheretheunitistobeinstalledandwhetheroptionalaccessories
aredesired.Gassupplypipingshouldalsobeplannedatthistime.
A gas shut off must be in this line.

The appliance, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes,
with the National Electrical Code, ANSI/NFPA 70, if an external
electrical source is utilized. This appliance is equipped with
a three-prong [grounding] plug for your protection against
shock hazard and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or remove the
grounding prong from this plug. Foranungroundedreceptacle,
anadapter,whichhastwoprongsandawireforgrounding,canbe
purchased,plugged intothe ungroundedreceptacleanditswire
connectedtothereceptaclemountingscrew.Withthiswirecom-
pletingtheground,theappliancecordplugcanbepluggedintothe
adapterandbeelectricallygrounded.
Caution: Labelallwirespriortodisconnectionwhenservic-
ingcontrols.Wiringerrorscancauseimproperanddangerous
operation.Verifyproperoperationafterservicing.
Note: Junctionboxonrightsideofreboxmustbepre-wiredat
timeofreboxinstallationforusewithblowerassembly.A
standardwall ON/OFFwall switchoroptional SCV1Vari-
ableSpeedControlKitshouldbeinstalledtoactivatepow-
er to the Firebox, and control the operation of the FBB5
Blowerassembly.Itisrecommendedthatinstallationofthe
wiringbeperformedbyaqualiedelectrician.See Figure
20.
1. Ifinstalled,turnOFFgassupplytorebox/gaslog.
2. Ifapplicable,turnOFFelectricsupplytorebox.
CAUTION: ALL WIRING SHOULD BE DONE BY A QUALI-
FIED ELECTRICIAN AND SHALL BE IN COMPLIANCE WITH
ALLLOCAL,CITYANDSTATEBUILDINGCODES.BEFORE
