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.

34829-3-0515Page 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).

VENTING FIREPLACE
To Use the Vent Graph
1. Determine the height of the center of the horizontal vent pipe. Using this dimension on the Sidewall Vent Graph, locate the point it
intersects with the slanted graph line.
2. Fromthepointofthisintersection,drawaverticallinetothebottomofthegraph.
3. Select the indicated dimension, and position the unit in accordance with same.
Special Note: Foreach45degreeelbowinstalledinthehorizontal
run,thelengthofthehorizontalrunMUSTbereducedby18"(45cm).
Thisdoesnotapplyifthe45degreeelbowsareinstalledonthe
verticalpartoftheventsystem.Reduce3'forevery90°elbow.
Example:According to the chart the maximum horizontal vent length
is20'andiftwo45degreeelbowsarerequiredinthehorizontal
ventitmustbereducedto17'.
Themaximumnumberof45degreeelbowspermittedpersidewall
installationistwo(2).Theseelbowscanbeinstalledineitherthe
vertical or horizontal run.
NOTE:Therstelbowdoesnotgetcounted.

The 7" (178mm) is measured from the center of the horizontal vent
pipe as it penetrates through the wall.
Ensure the sidewall venting clearances are observed. If venting
system is installed below ground, we recommend a window
well with adequate and proper drainage to be installed around
the termination area.

TERMINATION CLEARANCES
Vertical Sidewall Installations
Important!Minimumclearancebetweenventpipesandcombustible
materials is 3 inch (76 mm) on top, and 1 inch(25mm)onbottom
and sides.
Important! When vent termination exits through foundation less
than20inch(508mm)belowsidingoutcrop,theventpipemust
extend outward so that the horizontal vent termination is located
ushto,orbeyondtheoutcropsiding.
Information on Various Venting Routes and Components
Important:Itisalwaysbesttolocatethereplaceinsuchaway
thatminimizesthenumberofoffsetsandhorizontalventlength.
Sinceitisveryimportantthattheventingsystemmaintainitsbalance
betweenthecombustionairintakeandtheuegasexhaust,certain
limitations as to vent congurations apply and must be strictly
adhered to.
Thegraphshowingtherelationshipbetweenverticalandhorizontal
side wall venting will help to determine the various vent lengths
allowable.
The horizontal vent run refers to the total length of vent pipe from
theuecollarofthereplacetothefaceoftheouterwall.
Ventingterminationshallnotberecessedintowallorsiding.
