ROOF JACK
EXISTING FURNACE REPLACEMENT
If this furnace replaces an existing furnace, do the following:
1. If a 2nd roof, roof cap or addition has been made to the
existing roof of the home, remove the old roof jack com-
pletely! To avoid the possibility of an improperly installed
pipe or gaps in the old roof jack, INSTALL A NEW ROOF
JACK. Your ceiling and roof height will determine the cor-
rect roof jack to use. Refer to the vent selection table, of
the furnace installation instructions.
2. After unpacking the roof jack, check the rain caps. Insure
they are not damaged, tilted or crooked. Do not twist,
crush or sit on the roof caps during installation. Damaged
roof caps will cause improper furnace operation. The fur-
nace will not heat properly and could result in explosion.
3. Before inserting the roof jack into the furnace top,
inspect the furnace flue and combustion air opening for
debris or insulation which might have fallen in during pre-
installation steps. Do not proceed unless all debris has
been cleaned out or removed.
4. After installing roof jack on furnace top collar, check to
make sure there is no gap in back or side between the
pipe collar and the furnace casing top.
5. Use only the pipes provided with the roof jack assembly.
Do not add to or adapt other sheet metal pipes. Do not
cut, insert or add other pipes to this assembly.
6. In no case should there be a gap between sections of
the flue pipe or the combustion air pipe. If necessary to
prevent excessive air leakage, the installer should seal
joints in the combustion air tube with aluminum type or
other suitable sealant.
NEW HOME INSTALLATION
If this furnace is installed on a new home do the following:
1. Inspect the furnace top collars for signs of insulation or
ceiling debris which might have fallen in during cutting of
the ceiling and roof holes. Remove all debris before con-
tinuing.
2. After unpacking the roof jack, check the rain caps. Insure
they are not damaged, tilted or crooked. Do not twist,
crush or sit on the roof caps during installation. Damaged
roof caps will cause improper furnace operation. The fur-
nace will not heat properly and could result in explosion.
3. Before inserting the vent pipe into the furnace top,
inspect the furnace flue and combustion air opening for
debris or insulation which have fallen in during pre-instal-
lation steps. Do not proceed unless all debris have been
cleaned out or removed.
4. After installing roof jack on furnace top collar, check to
make sure there is no gap in back or side between the
pipe collar and the furnace casing top. If necessary to
prevent excessive air leakage, the installer should seal
joints in the combustion air tube with aluminum type or
other suitable sealant.
INSTALLATION IN SNOW REGIONS
When the combustion air pipe inlet is covered or blocked with
snow, the furnace will not operate properly due to the
depleted combustion air supply.
Therefore, if the furnace will be located in regions where
snow accumulation on the roof exceeds 7" or in H.U.D. Snow
Load Zones, a roof jack extension (Part No. 7680B6541) is
recommended.
LOCATING AND CUTTING ROOF JACK OPENING
To facilitate the proper installation of the roof jack, it is very
important that the roof jack opening in the ceiling and roof be
on the same vertical center line as the furnace flue collar. See
Figure 9.
Mark this location on ceiling and scribe a circle with a 5"
radius (10" diameter) around this mark. Cut opening for roof
jack through ceiling and roof. (If furnace was installed during
construction, cover furnace and flue opening to prevent
debris from entering flue when hole is cut for roof jack.)
INSTALLING ROOF JACK IN ROOF
(See Figure 6 & 7 for Dimensional requirements.)
Insert roof jack into opening in the roof.
The roof jack should be secured to the furnace before roof
flange (flashing) is secured to the roof. This will insure a bet-
ter alignment of the flue pipe and furnace flue collar. Caulk
around and under roof flange to provide a water tight seal,
before securing roof jack flashing to roof.
Failure to follow all venting instructions can result
in fire, asphyxiation, or explosion.
Only use the appropriate roof jack. See Figures 6
& 7 for correct application.
Do not exceed the maximum height as deter-
mined from Figures 6 & 7. Installer should allow
an additional 1-1/2" travel before the flue pipe
assembly is fully extended against the built-in
stop. This provides an additional safeguard
against the flue assembly being pulled from the
roof jack during transportation or other stress
conditions.

4. Determine which of the four positions the duct connector
best centers over the supply duct and insert it through
the floor cutout.
5. Mark cut-out location on the supply duct and remove the
duct connector.
6. Cut out the opening to the supply duct.
7. Bend tabs down through and back up under the supply
duct.
8. Secure the duct connector to the floor with nails, flat
head screws or staples.
The duct connector is designed for use on ducts down to 12"
in width. When using the connector on smaller width ducts,
there will not be sufficient clearance to bend the tabs on two
sides of the duct connector.
In such cases the tabs may be attached to the sides of the
duct by using sheet metal screws or other suitable fasteners.
Holes for sheet metal screws are provided in three (3) tabs on
each side of the duct connector. If more than 3 tabs need to
be used to provide a more secure and air tight connection,
the remaining tabs can also be fastened to the duct with
screws after drilling the required screw holes.

INSTALLATION OF THE FURNACE
1. Remove the front panels and set the furnace onto the
duct connector. Slide it back until the rear of the unit
engages the locator bracket.
2. Secure the front of the furnace with two screws at the
mounting holes provided.
3. Secure the top of the furnace to a structural member
using screw through the strap at the back of the furnace.
Strap may be moved to any of the holes located along
the top back of the furnace. Installer may provide an
equivalent method, such as screws through the casing
side.
NOTE: Combustion air tube and flue pipe are part of the
same assembly. Only the combustion air tube need be fas-
tened to the furnace.
1. Check to be certain that the flue pipe and combustion air
tube are present.
2. Pull the telescoping flue tube and combustion air tube
assembly down from the roof jack. Slide the flue tube/
combustion air tube assembly down firmly over the fur-
nace flue outlet and combustion air collar. Insure that the

CEILING RINGS
The ceiling ring is to meet fire stop requirements. Accessory
Ceiling Ring (P/N 7660-2841) may be used, (See Figure 15)
or the manufactured home manufacturer or the installer may
use other approved methods to stop fire.
If required, three (3) sections of Accessory Ring may be used
as shown in Figure 15 to provide closer clearance around
roof jack.
ELECTRICAL WIRING
CONNECT POWER SUPPLY WIRES
1. Remove the field wiring cover.
2. Insert 115 volt wires through the large plastic bushing on
the left side of the furnace (See Figure 16). If conduit is
used it should be secured to the control box.
3. Connect the “hot" wire to the BLACK pigtail lead, and the
“neutral" wire to the WHITE pigtail lead. Secure all con-
nections with suitable wire nuts and wrap with electrical
tape.
4. Connect the “ground" wire to the grounding screw.
5. Reinstall the control panel cover and secure mounting
screw.
CONNECT THERMOSTAT WIRES
1. Insert 24 volt wires through the small plastic bushing just
above the control panel.
2. Connect the thermostat wires to the furnace low voltage
pigtails. See Figure17 (heating only) and Figure 18
(heating and cooling).
3. Connect low-voltage circuit to the wall thermostat pig-
tails.
NOTE: Five-conductor thermostat cable is recommended for
all installations to allow easy installation of an air conditioning
system at a later time.
Eighteen gauge thermostat wire is highly recommended.
Smaller gauge thermostat wire may be used only if the guide-
line below is followed.
Do not use thermostat wire smaller than 22 gauge. If thermo-
stat wire smaller than 18 gauge is used, pay particular atten-
tion that the connections between the different wire sizes are
tight.
Operational problems may be caused by loose connections
or by the use of thermostat wire that is too small to carry the
required load. Any such problems are the responsibility of the
installer.
A separate 115 V.A.C. supply circuit must be used for the fur-
nace. The circuit should be protected by a 15 amp fuse or cir-
cuit breaker.

WALL THERMOSTAT
Avoid locations where the thermostat could be subject to
drafts from outside, or exposed to direct light from lamps,
sun, fireplaces, etc., or affected by air from a duct register
blowing directly on the thermostat.
The wall thermostat should be located 52 to 66 inches above
the floor. The preferred location is on an inside wall situated
in an area with good air circulation, and where the tempera-
ture will be reasonably representative of other living areas the
thermostat is controlling.
NOTE: In order to provide proper ventilation control when
using DGPH model furnaces with Coleman Blend
Air ventilation systems, it is required that a 4-wire
wall thermostat and Blower Relay Kit 7900-7761 be
installed.

GAS PIPING
INSTALLATION AND CHECKING OF GAS LINE
Gas Supply piping must be sized in accordance with the rec-
ommendations contained in National Fuel Gas Code (ANSI-
Z223.1, NFPA-54) unless local codes or regulations state oth-
erwise.
Materials used and pipe sizing for U.S. manufactured homes
must comply with requirements contained in Manufactured
Homes A119.1, Recreational Vehicles A119.2 and H.U.D.
Title 24, Section 3280.705 and any local or state codes.
NOTE: The gas line inlet on the gas valve is 1/2-14 N.P.T.
The gas line may be installed through the furnace floor or fur-
nace side to the gas valve.
A dirt leg may be required by some local codes to trap mois-
ture and contaminations.
For natural gas operation, the furnace is designed for 7" W.C.
inlet gas pressure. Pressure to main burner is then reduced
to 3 1/2" W.C.
For Propane gas operation, the furnace is designed for 11"
W.C. inlet gas pressure. Pressure to main burner is then
reduced to 10" W.C.
IMPORTANT - When converting gas valve from or to Pro-
pane gas, it will be necessary to change main burner orifice
to prevent an underfired or overfired condition. See label
inside lower furnace door for complete instructions.
Pilot Adjustment
On models equipped with standing pilot ignition, the pilot
should be adjusted so that the flame is approximately 1” in
height (500 BTU / hr.). This will allow proper burner ignition
without excessive fuel usage. The pilot adjustment screw is
located on the top of the gas valve.
Observing Burner Operation
1. Observe burner to make sure it ignites. Observe color of
flame. On natural gas the flame will burn blue with appre-
ciably yellow tips. On Propane gas a yellow flame may
be expected. If flame is not the proper color call a quali-
fied service technician for service.
2. Let furnace heat until blower cycles on.
3. Turn thermostat down.
4. Observe burner to make sure it shuts off.
5. Let the furnace cool and blower cycle off.
If any abnormalities are observed when checking for correct
operation, such as burner failing to ignite or to turn off, sooty
flame, etc., call your nearest authorized service technician as
shown in the Service Center List included in the home owner
envelope with the furnace.
If Furnace Fails to Operate Properly
1. Check setting of thermostat - and position of HEAT/
COOL switch if air conditioning is installed. If a set-back
type thermostat is employed be sure that the thermostat
is in the correct operating mode.
2. Check to see that electrical power is ON.
3. Check to see that the knob or switch on the gas control
valve is in the full ON position.
4. Make sure filters are clean, return grilles are not
obstructed, and supply registers are open.
5. Be sure that furnace flue piping is open and unob-
structed.
If the cause for the failure to operate is not obvious, do not
attempt to service the furnace yourself. Call a qualified ser-
vice agency or your gas supplier.
To install gas line and to connect it to the gas
valve, care must be taken to hold gas valve firmly
to prevent misalignment of the burner orifice, or
to damage gas valve which could result in
improper heating, explosion, fire or asphyxiation.
DO NOT USE EXCESSIVE PIPE SEALANT ON
PIPE JOINTS. Pipe sealant, metal chips or other
foreign material that could be deposited in the
inlet of the gas valve, when gas pipe is installed
or carried through the gas piping into the gas
valve inlet after installation, may cause the gas
valve to malfunction and could result in possible
improper heating, explosion, fire or asphyxiation.
Also, pipe sealant must be resistant to Propane
gas.
Where regulations require, a main shut-off valve
shall be installed externally of furnace casing.
After piping has been installed, turn gas on and
check all connections with a leak detector or
soap solution.
Never use open flame to test for gas leaks as
fire or explosion could occur.
Do not test the fuel system at more than 14" W.C.
after furnace has been connected to fuel line.
Such testing could void the warranty. Any test run
above 14" W.C. may damage furnace control
valve which could cause an explosion, fire or
asphyxiation.
If the gas input to the furnace is too great
because of excessive gas pressure, wrong size
orifice, high altitude, etc., the burner flame will be
sooty and may produce carbon monoxide, which
could result in unsafe operation, explosion, and/
or fire or asphyxiation.
Should overheating occur, or the gas supply fail
to shut off, shut off the manual gas valve to the
furnace and allow burner to run until furnace
cools down and blower shuts off before shutting
off the electrical supply.

FINAL PROCEDURE
INSTALL FURNACE DOORS
Install the lower door first by sliding the bottom of the door
down until the tabs on the casing base engage the slots in the
bottom door end cap. Then push the top of the lower door in
until the door clips snap into place. Install the upper door in a
similar manner, first engaging the slots in the top of the upper
door on the tabs on the casing top. Then snap the bottom of
the upper door into place against the casing.
FINISH AND TRIM
Alcove and Closet Installations may now be finished and
trimmed as necessary.
FURNACE AND AIR CONDITIONER
INSTALLATIONS
If an air conditioner is installed which does not use the blower
for air distribution and operates completely independent of
the furnace, the thermostat system must have an interlock to
prevent the furnace and air conditioner from operating at the
same time. This interlock system usually contains a heat-cool
switch which must be turned to either HEAT or COOL to acti-
vate either heating or cooling operation, or a positive OFF
switch on the cooling thermostat.
When used in connection with a cooling unit the furnace shall
be installed parallel with or on the upstream side of the cool-
ing unit to avoid condensation in the heat exchanger.
For installations with a parallel flow arrangement, the furnace
must be equipped with a damper to prevent cold air from
being discharged up around the heat exchanger. Cold air
causes condensation inside the exchanger and can cause it
to rust out which can allow products of combustion to be cir-
culated into the living area by the furnace blower resulting in
possible asphyxiation. An air flow activated automatic
damper, P/N 7900-6771, is available from furnace manufac-
turer. See Figure 24.
NOTE: See label on coil panel for conversion and lighting
instructions. Obtain a temperature rise within the ranges
specified on the name plate.
