10. This unit complies with ANSI Z21.11.2 Unvented
Heaters.
11. Do not install heater in a bathroom or bedroom unless
approved for bedroom use.
12. Correct installation of the ceramic ber logs, proper
locationoftheheater, andannualcleaningareneces-
sarytoavoidpotentialproblemswithsooting.Sooting,
resultingfrom improper installation oroperation, can
settleonsurfacesoutsidethereplace.Seelogplacement
instructions for proper installation.
13. Avoidanydraftsthatalterburneramepatterns.Donot

can produce odors. It is recommended to minimize the
useofcandles,incense,etc.whilethevent-freeappliance
is in operation.
15. Thisisanunventedgas-redheater.Itusesair(oxygen)

vided. See page 8.
IMPORTANT
Read these instructions carefully before installing or trying to operate this vent-free gas heater.
IMPORTANT SAFETY INFORMATION
8. CARBON MONOXIDE POISONING:Earlysignsof
carbonmonoxidepoisoningaresimilartotheuwith
headaches,dizzinessand/ornausea.Ifyouhavethese
signs, obtain fresh air immediately. Have the heater
servicedasitmaynotbeoperatingproperly.
9. Theinstallationmust conformwith localcodesor,in
theabsenceoflocalcodes,withtheNational Fuel Gas
Code, ANSI Z223.l/NFPA54. Continued on page 4
WARNING
• Any change to this heater or its controls can be dangerous.
• Improper installation or use of the heater can cause serious injury or death from fire,
burns, explosion or carbon monoxide poisoning.
• Do not allow fans to blow directly into the stove. Avoid any drafts that alter burner
flame patterns.
• Do not use a blower insert, heat exchanger insert or other accessory, not approved
for use with this heater where applicable.
1.Duetohightemperatures,theapplianceshouldbelocated
outoftrafcandawayfromfurnitureanddraperies.
2. Children and adults should be alerted to the hazard of
highsurfacetemperatureandshouldstayawaytoavoid
burnsorclothingignition.
3.Youngchildrenshouldbecarefullysupervisedwhenthey
are in the same room with the appliance.
4.Donotplaceclothingorotherammablematerialonor
near the appliance.
5.Anysafetyscreenorguardremovedforservicinganappli-
ance,mustbereplacedpriortooperatingtheheater.
6.Installationandrepairshouldbedonebyaqualiedser-
vice person.
7.Topreventmalfunctionand/orsooting,anunventedgas
heater should be cleaned before use and at least annually
by a professional service person. More frequent clean-
ingmayberequiredduetoexcessivelintfromcarpet-
ing,beddingmaterial,etc.Itisimperativethatcontrol

16. Keep room area clear and free from combustible materi-
als,gasolineandotherammablevaporsandliquids.
17. Unventedgasheatersareasupplementalzoneheater.
They are not intended to be a primary heating appli-
ance.
18. Unventedgasheatersemitmoistureintothelivingarea.
Inmosthomesofaverageconstruction,thisdoesnotpose
aproblem. In houses of extremelytight construction,
addition mechanical ventilation is recommended.
19. Duringmanufacturing,fabricatingandshipping,various
components of this appliance are treated with certain
oils,lmsorbondingagents.Thesechemicalsarenot
harmfulbutmayproduceannoyingsmokeandsmells
astheyareburnedoffduringtheinitialoperationofthe
appliance;possibly causing headaches or eyeor lung
irritation. This is a normal and temporary occurrence.
  Theinitialbreak-inoperationshouldlasttwotothree
hours with the burner at the highest setting. Provide
maximumventilationbyopeningwindowsordoorsto
allowodorstodissipate.Anyodorsremainingafterthis
initialbreak-inperiodwillbeslightandwilldisappear
with continued use.
20. Inputratings are shownin BTU per hourand are for
elevationsupto2,000feet.Forelevationsabove2,000
feet,inputratingsshouldbereduced4percentforeach
1,000feetabovesealevel.RefertotheNationalFuel
Gas Code.
21. Theapplianceanditsappliancemaingasvalvemustbe
disconnectedfromthegassupplypipingsystemduring
anypressuretestingofthatsystemattestpressuresin
excessof1/2psig(3.5kPa).
22. The appliance must be isolated from the gas supply

23. Do not use this room heater if any part has been under
water.Immediately call aqualied service technician
to inspect the room heater and to replace any part of the
controlsystemandanygascontrolwhichhasbeenunder
water.

GENERAL INSTALLATION INFORMATION
Thefollowingformulacanbeusedtodeterminethemaximumheaterratingperthedenitionofunconnedspace:
BTU/Hr = (L1+ L2) Ft x (W) Ft x (H) Ft
50
Considertwoconnectingroomswithanopenareabetween,withthefollowingdimensions:
L1= 151/2Ft., L2= 12 Ft., W = 12 Ft., H = 8 Ft.
BTU/Hr = (151/2 + 12) x (12) x (8)
50
If there were a door between the two rooms the calculation would be based only on the room with the heater.
BTU/Hr = (151/2) x (12) x (8)

WARNING
If the area in which the heater may be operated is smaller than that defined as an
unconfined space or if the building is of unusually tight construction, provide adequate
combustion and ventilation air by one of the methods described in the National Fuel
Gas Code, ANSI Z223.1, NFPA54, Section 5.3 or applicable local codes.

Locations that the Pressure
Tapping Point May Be Installed
CAUTION
Use new black iron or steel pipe. Internally tinned copper or copper tubing can be used
per National Fuel Code, section 2.6.3, providing gas meets hydrogen sulfide limits, and
where permitted by local codes. Gas piping system must be sized to provide minimum
inlet pressure (Listed on Data Plate) at the maximum flow rate (BTU/Hr). Undue pressure
loss will occur if the pipe is too small.
A manual shutoff valve must be installed upstream of the appliance. Union tee and
plugged 1/8" NPT pressure tapping point should be installed upstream of the appliance.
See Figure 10.
CAUTION
CHECK GAS TYPE: The gas supply must be the same as stated on the heater’s rating
plate. If the gas supply is different, DO NOT INSTALLTHE HEATER. Contact your dealer
for the correct model.

WARNING
The positioning of the logs are critical to the safe and clean operation of this heater.
Sooting and other problems may result if the logs are not properly and firmly positioned
in the appliance. Never add additional logs or embellishments such as pine cones,
vermiculite or rock wool to the heater. Only use the logs supplied with the unit.
Failure to position the parts in accordance with diagrams below or to use only
parts specifically approved for this heater may result in property damage or
personal injury.

During initial operation of the new
heater, burning logs will give off
a paper burning smell and orange
flames will be present. Simply open
the windows for a few hours to vent
the odor.

Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed.
Inaddition,periodicallychecktheamesvisuallyduringoperation.
CHECKING PILOT FLAME
The pilot flame must always be present when the heater is in operation. It should just touch the top of the ther-
mocouple tip for natural. See Figure 17 forcorrectpilotame.
Ifthepilotamedoesnottouchthethermocouple,thentheburnerscannotfunctionreliably.See Figure 18 for incorrect

In normal operation at full rate after 15 minutes, the following flame appearances should be observed:
Theleftandrightrearamesshouldbeyellowandextend1"-2"abovemiddlelogs.Theyellowamesshouldnot contact

OPERATING INSTRUCTIONS
Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the stove. Do not place
ablowerinsidetheburnareaofthestove.Ceilingfansmaycreatedraftsthatalteramepatterns.Sootingandimproper
burningwillresult.
Duringmanufacturing,fabricatingandshipping,variouscomponentsofthisappliancearetreatedwithcertainoils,lmsor
bondingagents.Thesechemicalsarenotharmful,butmayproduceannoyingsmokeandsmellsastheyareburnedoffduring
theinitialoperationoftheappliance,possiblycausingheadachesoreyeorlungirritation.This is a normal and temporary
occurrence.
Theinitialbreak-inoperationshouldlasttwotothreehourswiththeburneratthehighestsetting.Providemaximumventila-
tionbyopeningwindowsordoorstoallowodorstodissipate.Anyodorsremainingafterthisinitialbreak-inwillbeslight
and will disappear with continued use.
