Step 3: Choose a Location for Your Heater
In choosing a location for yourheater, the following
guidelinesmust be considered:
•Theheater maybe installed on combustibleflooring on
the metaltrayprovided.
•The area around the heatershould be free of obstacles
thatmightinterferewith the freeflow of air. Allow the
clearances shown in Figure 4.
•Theheatermust notbe installed ina fireplace.
•AnAC walloutletmust be withinreach ofthe heater's
power cord.Extensioncordsmust notbe used.
•The area outsidewhere the fluepipewillemergeshould
be free of foliage,fuelstoragetanks and flammable
objects. Air shouldcirculatefreely inthe area.Allow the
clearances shown in Figure 6 onthe nextpage.
•Refer to Figure 4to provide adequateaccessibility clearances
for servicing.
•Thewallwherefluepipeholewill becut should be free of
plumbingpipes,electricalwires,studs, air ducts and other
obstacles.
NOTE: L/se the cardboard templateprovided with your
heater for flue pipelocation.

Step 4: Drill a Pilot Hole
NOTE:The following directions apply to "standard"
installation. For other methods, follow instructions
included with accessory kits.
For walls up to 8Y2 inches (21.59cm) thick, use a
short flue pipe; for walls up to 141/^ inches
(36.83cm) thick, use a medium flue pipe; and for
walls up to 20 inches (50.80cm) thick use a long
flue pipe.
Use the template to position the hole tobe drilled. The
"bluedot"indicates the exactcenter ofthe hole.Using
an electric drill anda long drill bit, make a pilot hole
through the wall(Figure 5).Be sure the holeextends
through the outsidewall.

^CAUTION: The opening on the inside wall should
be approximately '/4 inch higher than onthe outside
wall so the flue pipe will slope downward when
installed. This will allow condensation to drain
outdoors.

FLUE PIPECLEARANCES
• Vent terminalmust be located at least 3 feetabove any forced air inletlocatedwithin 10 feet.
•The ventterminal ofa directventappliancewith an input of 50,000 Btuper hour or lessshall be located at least 9
inches from any openingthroughwhichfluegasescouldenter a building, and such an appliancewith an input over
50,000 Btuper hourshallrequire a 12-inch ventterminationclearance. The bottom ofthe ventterminal andtheair
intake shall be located at least 12 inchesabovegrade.

Step 5:Cutthe Hole forthe Fluepipe
Using a hole saw attachment andan electric drill, cuta 21/2
inch diameterholethrough the inner and outerwalls
figure 7).
After the hole is cut, usea straightedge anda level to
be sure the insideopening is approximately
1A
inch
higher than the outsideopening.
NOTE: After cutting the inside wall, remove the
insulation. Make sure there are no obstructions
inside the wall, such as electrical wiring, water
pipes, hot air ducts,etc.
Step 6: Install the FluePipe
FromINSIDE the building, insert the fluepipe(with
arrow pointing "up")into the hole.Fasten the fluepipe
with the3 #8x3A tapping screws(Figure 8).
(See Figure 3 for screwsize and application.)
NOTE: Top center port is an extra exhaust port.

Holding the "Up"mark tothe top, slide the rubber
packingonto the sleeve(caulkside tothe wall).
NOTE: If it is difficult to slide the packing onto the
sleeve, apply soapy water to the inside of the
packing.
Once the rubberpacking isin place,slide the outer
flange onto the sleevewith the conicalsidepointing

Step 8: Level the cabinet
Place the tray onthe floorwhere you plan to located
your heater.
Position the heater onthe tray sothe legs ofthe
cabinet fit into the circularindentation inthe tray.
In order for heater to operateproperly. It must be
positioned ona levelsurface.Ensureproperleveling by
adjustingeach legandby using a carpenterslevel to
check both side to side, and front to backlevel
condition.(Figure 11)
Step 10: Connect the Heater tothe FluePipe
Move the heatertoward the wall,guiding the jointpipe
into the centerport ofthe fluepipe(Figure 13).
Be sure the jointpipe is completelyinsertedinto the
fluepipe.

Step 9: Install the JointPipe
At the rear ofthe heater,slide the large end opening of
the jointpipeinto the exhaustportoutlet ofthe heater.
Be sure the joint pipe is fully seated. Slide the fabric
cover over the jointpipe(Figure 12).
The o-rings thatseal the jointpipe maybedryand
tight. A little soapywaterwilleaseinstallation.
Step 11: Install theAir Damper
If installation is standard(that isno extensionkits are
required),place theair dampermarked with a
"STANDARD" over theair intakeflange onthe fluepipe
(Figure14).
Place the hosebandaround theendoftheair supply
hose.Push theair supplyhoseonto theair intake
flange and secure the hosewith the hoseband.

NOTE: The "STANDARD" damper is to be used with
extension kits up to a total overall length of 20
inches and a maximum of 3 bends (90° elbow).
The "EXTENSION" damper must be used when
extension kit or kits exceed 20 inches.
Step 12: Install the Flue Pipe Holder
Place the ring ofthe flue pipe holder around the flue
pipe. The otherside ofthe holder hooks ina slot
directlyabove the jointpipe atthe rear ofthe heater
(See Figure15).
Step 14: Recheck the Heater
Beforeproceeding,checkagain tobe surethere areno
flammablematerialsclose tothe heater.Check tobe
sure the heater is level.
Examine the fluepipe tobe sureconnections are tight.

STARTING INSTRUCTIONS
•Step 1: Plug inthe Heater
Plug intheAC cord, and route it away from the area ofthe
flue pipe. Itis recommendedthat no otherappliance share
the same outlet.
NOTE: When the unit is operated for the first time or the
gas piping is replaced, the unit may not come ON
the first few times since air is in the piping. In this
case, repeat the starting procedures.
Step 2:Set "ON"Button
Depress the operationbutton toputitinthe "ON"
position(Figure 17).The "RUN"Lamplightsindicating
"Set Room Temperature" and "Present Room Temperature".
Burnerstatuslamps will light and ignition willstartafter
approximately 20 seconds. In30 seconds the circulation
fan willstart to operate, and warm air will be feltcoming

NOTE: The heater may display room temperature 4 degrees above set temperature, depending on heater load
conditions, before shutting itself off.
INSTRUCTIONS FOR ECONOMYPLUSMODE
To engage the economyplusmode,simplypressdown the button labeled "EconomyPlus", to disengagepressagain.
NOTE: Operation switch must be "ON" and in manual mode.
Thisfeatureminimizes the "ON" and "OFF"cycling ofthe unit by allowing itto overshoot theset temperature by12
degreesinstead ofthe normal 4 degrees.
The advantages of thisfeature areto increase the overallefficiency ofthe unit by:
1. Reducingheatloss during the prepurge and postpurgecycles.
2. Reducinginefficientcombustionassociatedwithstart upand shutdown.
3. Prolongingcomponentlife by decreasingexpansion and contraction of internalparts.
