After picking a location that meets the requirements, inspect the wall, floor and outside areas. Make sure there
are no pipes, wiring, or anything else that would interfere
with furnace or vent or thermostat installation. If required,
move them or pick a new location.
2203621,
(All other models have a built-in thermostat)
Choose a location for the thermostat about 5 feet above
the floor on an inside wall. The thermostat wire supplied
with your furnace is 20 feet long, which should be enough
to run up through the attic so the thermostat can be a maximum of 16 feet from furnace measured in a straight line,
or approximately 12 feet from the furnace if the wire is run
under the floor. The thermostat should be sensing average
room temperature, avoid the following:
Installation
BEFORE YOU BEGIN: To avoid electrical shock turn off
electrical circuits that pass through the wall where you are
going to install the furnace.
Make sure the inside and outside wall openings
aligned so tubes and vent will fit properly.
are
IN NEW CONSTRUCTION frame in 9-1/4 inch x 9-1/4 inch
opening centered between studs spaced 16 inches on
center, and center point located as noted per Fig. 3.
This furnace must be installed using only the vent tube,
air inlet tube and vent cap assembly supplied by the
manufacturer.
Before the furnace is installed an opening must be cut
through the wall for the vent cap.
i
NOllE: S-I./,, x 9-1/40I:'£NblG MAYBE ROUNDOR SQUARECUT.
FIND THE STUDS
Find the studs where the furnace is to be placed. Use a
stud Iocator or small finishing nails. Repeatedly drive and
remove a nail into the wall in the area of the stud until you
find it. Then find one side. Leave the nail there. Drive
another nail just on the other side of the same stud.
The inside edge of the other stud should be about 14-1/2
inches from the one found. Drive a finishing nail on the
inside edge of this stud, then another nail on the outside
edge.
Using a level, draw vertical lines that will represent the
two stud center lines.
CUT VENT OPENING
After locating studs, use the cardboard template (Fig. 4,
page 8). Line up the CENTER OF STUD lines on the
template with the center lines you have drawn on the wall.
Use the template to draw the 9-1/4 inch diameter circle on
the wall. Then mark the location of the gas supply line.
Using a window, door or wall corner for reference, measure
to find where vent will be on outside wall. Check to be sure
of proper clearances (Figs. 1 and 2, page 6). If necessary,
relocate for proper clearances.
Drill a 1/4 inch hole in the wall at the vent opening center
mark all the way through to the outside. Cut the 9-1/4 inch
diameter hole through inside wall. Using the 1/4 inch hole
as center, cut a matching hole in outside wall. It may be
petter to work from the outside when breaking through
brick, stone or tile.

4. Replace junction box cover.
Blower will not operate unless fan switch is pulled to "On"
position, either "High" or "Low." To check "On" position,
turn automatic fan switch "E" to 70, then pull chain on
switch to obtain High, Low or Off position. Set the fan
switch dial at 110 and readjust higher or lower as
necessary to obtain blower operation within 4 to 5 minutes
after the main burner is in operation.
5. After blower and junction box are installed, rotate
bushing "H" if needed to prevent motor wire binding
against blower case.
The unit must be electrically grounded in accordance with
ANSI/NFPA 70 current edition of the "National Electrical
Code." In Canada: FollowC22.1 Canadian Electrical Code.

Start-Up
Procedure
Start the furnace using the procedures in section
Operating Your Furnace on pages 15 through 19.
CHECK THE GAS INPUT (NATURAL GAS ONLY)
WARNING
WARNING
NATURAL GAS HEATING VALUE (BTU PER CUBIC
FOOT) CAN VARY SIGNIFICANTLY, THEREFORE,
IT IS THE INSTALLER'S RESPONSIBILITY TO SEE
THAT BTU INPUT TO THE FURNACE IS ADJUSTED
PROPERLY. FAILURE TO DO SO COULD CAUSE
HEAT EXCHANGER FAILURE, ASPHYXIATION, FIRE
OR EXPLOSION, RESULTING IN DAMAGE, BODILY
INJURY OR DEATH. REFER TO THE NATURAL
FUEL GAS CODE (NFPA-54) TO BE SURE THE FURNACE IS BURNING FUEL AT THE PROPER RATE.
DANGER OF BODILY INJURY OR DEATH
LIQUEFIED PETROLEUM (L.E) GAS IS HEAVIER
THAN AIR AND IT WILL SETTLE IN ANY LOW
AREA, INCLUDING OPEN DEPRESSIONS AND IT
WILL REMAIN
THERE
UNLESS
AREA IS
VENTILATED.
NEVER ATTEMPT START-UP OF UNIT BEFORE
THOROUGHLY VENTILATING AREA•
Check the furnace operation as outlined in the following
instructions• If any sparking, odors or unusual noises are
encountered,
shut off electrical power immediately.
Recheck for wiring errors, or obstructions in or near optional blower motor•
NOTICE:
During the initial firing of this unit some smoke and odor
may occur• We recommend ventilating the area during this
initial "break in period."
CHECK GASlNPUT
AND PRESSURES
For furnace located at altitudes between sea level and
2000 feet, the measured input must not be greater than
the input shown on the rating plate of the furnace. For
elevations above 2000 feet, the measured input must not
exceed the input of the rating plate reduced by 4 percent
for each 1000 feet that the furnace is above sea level.
Gas supply pressure and manifold pressure with the
burners operating must also be as specified on the rating
plate.
TYPE OF GAS
Natural
L.R
MANIFOLD
Underfiringcould cause inadequate heat, excessivecondensation or ignition problems. Overfiring could cause sooting flame impingement or overheating of heat exchanger•
Before starting natural gas input check, obtain heating
value of gas (BTU per cubic foot) at standard conditions
from your local supplier. This factor is used in "Check the
Gas Input" section and procedure.
To measure the input using the gas meter, proceed as
follows:
Step 1: Turn off gas supply to all other appliances except
the furnace.
Step 2: With the furnace operating, time the smallest dial
on the meter for one complete revolution. If this
is a 2 cubic foot dial, divide the seconds by 2; if
it is a 1 cubic foot dial, use the time in seconds
as is. (3,600 = Sec. Per Hr.) This gives the
seconds per cubic foot of gas being delivered to
• the furnace.
Step 3: Assuming natural gas with a heating value of 1000
Btu per cubic foot and 34 seconds per cubic foot
as determined by step (2), then:
Input: 1,000 X 3,600 + 34 = 106,000 Btu Per Hour
This measured input must not be greater than the
input indicated on the rating plate of the furnace.
PRESSURE, IN. W.C.
Step 4: Relight all other appliances turned off in step 1
above. Be sure all pilot burners are operating.

11
ADJUST PILOT BURNER
Rated input will be obtained on 2500 B'FU propane at 11
inches manifold pressure with factory-sized orifices. If L.R
Gas having a different heating value is supplied, orifices
must be changed by a qualified installer before the furnace is operated•
CHECK THE MANIFOLD GAS PRESSURE
NOTE: Pilot gas may need adjustment depending on inlet
pressure, increase or decrease to obtain proper
setting.
Pilot flame should surround 3/8 inch to 112inch of the thermocouple tip. To adjust, if needed, remove pilot adjustment
cap (do not lose gasket).
1,
A tapped opening is provided in the gas valve to facilitate
measuring the manifold gas pressure. A "U Tube"
manometer having a scale range from 0 to 12 inches of
water should be used for this measurement. The manifold
pressure must be measured with the burner and pilot
operating. Any major changes in the flow must be made
by changing the size of the burner orifice. Check with local
gas company for proper orifice size.
Remove screw cover over pilot adjusting screw.
2. Insert small screwdriver. Adjust flame as needed. Turn
screw counterclockwise (I¢-_) to increase flame,
clockwise (_)
to decrease.
3. Turn thermostat to highest setting. Main burners should
light quickly and smoothly. Turn thermostat to lowest
setting. Main burners should go out. Pilot should remain lighted.
4. Replace screw cover over pilot adjusting screw.

WARNING
DO NOT STORE OR USE GASOLINE OR OTHER
FLAMMABLE LIQUIDS OR VAPORS NEAR THE
FURNACE.
THE SURFACE OF THE FURNACE IS HOT DURING OPERATION. KEEP CHILDREN, CLOTHING,
FURNITURE, AND FLAMMABLE MATERIAL AWAY
FROM IT.
On new installations the gas lines will be filled with air and
it may take several tries to establish the pilot flame.
LIGHTING THE FURNACE WITH A MATCH
Check the manual shut-off valve in the gas line. It must
be in the open position (handle parallel to gas line) before
you can light your furnace.
If the spark ignitor fails to provide spark to light the pilot,
loosen the wing nut holding the peep hole cover. This will
open the peep hole into the heat exchanger and the pilot
can be ignited with a match.
Your furnace is equipped with a 100% safety pilot which
will shut off the gas valve in case the pilot is not burning
or functioning properly. Make sure the pilot is adjusted properly and that the thermocouple or generator connection
at the control valve is tight. If furnace will not stay lit, call
your local gas utility company.
1. Follow the instructions
under "LIGHTING
AND
OPERATING INSTRUCTIONS" and use a match to
light the pilot as instructed.
WARNING
Your furnace is equipped with a built-in pressure regulator.
L.R Gas models also have a regulator at the supply tank.
If you have a question regarding the amount of fuel
consumed, call your local gas utility or gas supplier. DO
NOT TAMPER WITH THE REGULATORS OR BURNER
ORIFICES, AS PROBLEMS RESULTING THEREFROM
MAY CAUSE PRODUCT FAILURE NOT COVERED BY
