ROOF JACK

AWARNING

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

[AkCAUTION

Only use the appropriate roof jack. See Figures 6

& 7 for correct application.

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.

EXISTING FURNACE REPLACEMENT

If this furnace replaces an existing furnace, do the following: f.

If a 2nd roof, roof cop or addition has been made to the existing roof of the home, remove the old roof jack completely! To avoid the possibility of an impropedy 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.

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 cape during installation. Damaged roof cape will cause improper furnace operation. The furnace 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 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.

6.

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.

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 installedon 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.

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 cops will cause improper furnace operation. The furnace 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 insulationwhich 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 end 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 reef 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 secoring roof jack flashing to roof.

Do not use thermostat wire smaller than 22 gauge. If thermostat wire smaller than 18 gauge is used, pay particular attention 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 _/A.C. supply circuit must be used for the furnaco. The circuit should be protected by a 15 amp fuse or circuit breaker.

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 temperature 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 recommendations contained in National Fuel Gas Code (ANSI-

Z223.1, NFPA-54) unless local codes or regulations state otherwise.

Matedals used and pipe sizing for U.S. manufactured homes must comply with requirements contained in Manufactured

Homes Al19.1, Recreational Vehicles Al19.2

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.ET

The gas line may be installed through the furnace floor or furnace side to the gas valve.

F& CAUTION

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 bumer 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 shaft be installed externally of furnace casing.

After piping has been installed, turn gas on and check aft 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" HZC. after furnace has been connected to fuel line.

Such testing could void the warranty. Any test run

above 14" WC.

may damage furnace control valve which could cause an explosion, fire or asphyxiation.

I CAUTION!

If the gas input to the furnace is too great because of excessive gas pressure, wrong size orifice, high altitude, etc., the burnerflame 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 cedes to trap moisture and contaminations.

035-16328-002 Rev. C (0902)

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.

2,

3.

4.

5.

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.

Let furnace heat until blower cycles on.

Turn thermostat down.

Observe burner to make sure it shuts off.

Let the furnace cool and blower cycle off.

kWARNING]

Should overheating occur, or the gas supply fail

to shut off, shut off the manual gas valve to the furnace and allow bomer to run until furnace cools down and blower shuts off before shutting off the electdcal supply.

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.

2.

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.

3.

4.

5.

Check to see that electrical power is ON.

Check to see that the knob or switch on the gas control valve is in the full ON position.

Make sure filters are clean, return gdfies are not obstructed, and supply registers are open.

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 ser- vice agency or your gas supplier.

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.

/ AUTOMATIC

DAMPER

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 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, PIN 7900-6771, is available from furnace manufacturer. 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.
