ROOF JACK

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 continuing.

2.

Only use the appropriate roof jack. See Figures 6
& 7 for correct application.

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 furnace will not heat properly and could result in explosion.

3.

Do not exceed the maximum height as determined 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.

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-installation 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.

Failure to follow all venting instructions can result
in fire, asphyxiation, or explosion.

EXISTING FURNACE REPLACEMENT
If this furnace replaces an existing furnace, do the following:

INSTALLATION IN SNOW REGIONS

1.

If a 2nd roof, roof cap or addition has been made to the
existing roof of the home, remove the old roof jack completely! 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 correct roof jack to use. Refer to the vent selection table, of
the furnace installation instructions.

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.

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 furnace will not heat properly and could result in explosion.

LOCATING AND CUTTING ROOF JACK OPENING

2.

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 preinstallation 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.

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.

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.
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 better 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.

8.

Cut out the opening to the supply duct. If sealant was not
used, the installer should tape the mating flanges to provide a good air seal.

NOTE: Duct sealant and tape must be classified as
meeting HUD Standard 3280.715, U.L. Standard 181A.
If tape is used to provide a better air seal, it should be a type
approved by the applicable national or local codes.

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.

GAS PIPING
INSTALLATION AND CHECKING OF GAS LINE
Gas Supply piping must be sized in accordance with the recommendations contained in National Fuel Gas Code (ANSIZ223.1, NFPA-54) unless local codes or regulations state otherwise.
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 furnace side to the gas valve.

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.

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 Propane 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 appreciably yellow tips. On Propane gas a yellow flame may
be expected. If flame is not the proper color call a qualified 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.

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.

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.
A dirt leg may be required by some local codes to trap moisture and contaminations.

Unitary Products Group

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 unobstructed.

If the cause for the failure to operate is not obvious, do not
attempt to service the furnace yourself. Call a qualified service agency or your gas supplier.

FINAL PROCEDURE

FURNACE AND AIR CONDITIONER
INSTALLATIONS

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.

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 activate 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 cooling 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 circulated 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 manufacturer. See Figure 24.
