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 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.

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 com- pletely! 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 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 cape during installation. Damaged roof cape 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 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 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 cops 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 insulationwhich 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 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 bet- ter 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.
