Television Considerations
Installingatelevision above a replace has become adesirable
feature;however,thefollowinginformationshouldbeconsidered.
All replaces, whether decorative or heater rated create heat.
Most television manufacturers recommend not placing a television
near a heat source. Because there is a large variety of television
manufactures, styles and sizes, it is impractical to test every potential
installation.Ifyouchoosetoinstallatelevisionaboveornearyour
replace, understand that Empire Comfort Systems accepts no
responsibilityforthisdecisionandanyinjuryordamageduetothis
applicationisthesoleresponsibilityoftheowner.Additionally,itis
highlyrecommendedtoturnoffthereplaceandletitcooldown
before servicing or using the operational buttons located on the
television. In all cases, the television manufacturer’s instructions
andwarningsshouldbefollowed.
Combustible Material
No greeting cards, stockings or ornamentation of any type should
beplacedonorattachedtothereplace.Theowofheatcanignite
combustibles.SeeFigure3.

34829-1-0115Page 8
GAS SUPPLY
The gas pipeline can be brought in through the left side of the
appliance. Consult the current National Fuel Gas Code,ANSI Z223.1

Notice:Neveruseplasticpipe.Checktoconrmwhetheryourlocal
codesallowcoppertubingorgalvanized.
Notice:Since some municipalities have additional local codes, it
isalwaysbesttoconsultyourlocalauthorityandinstallationcode.
The use of the following gas connectors is recommended:
— ANSIZ21.24ApplianceConnectorsofCorrugatedMetalTubing
and Fittings.
— ANSI Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
Theaboveconnectorsmaybeusedifacceptablebytheauthority
having jurisdiction. The state of Massachusetts requires that a
exibleapplianceconnectorcannotexceedthreefeetinlength.

Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
Amanualmaingascockshouldbelocatedinthevicinityoftheunit.
Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compoundsusedonthreadedjointsofgaspipingshallberesistant
totheactionofliqueedpetroleumgases.Thegaslinesmustbe
checkedforleaksbytheinstaller.Thisshouldbedonewithasoap
solutionwatchingforbubblesonallexposedconnections,andif
unexposed,apressuretestshouldbemade.
Never use an exposed ame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
Notice:The gas controls are equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8"
test point up stream of the control.
Whenusingcopperorexconnectoruseonlyapprovedttings.
Theapplianceandit’sindividualshutoffvalvemustbedisconnected
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5kPa).
Theappliancemustbeisolatedfromthegassupplypipingsystem
byclosingitsindividualmanualshutoffvalveduringanypressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (3.5kPa).
Attention! If one of the procedures results in pressures in excess of
1/2psig(14"w.c.)(3.5kPa)onthereplacegasvalve,itwillresult
in a hazardous condition.
Checking Manifold Pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5" w.c. (.871kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 5.0" w.c.
(1.245kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa). Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8" w.c.
(2.68kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa).
