DOWNWARD VENTING

In some applications, it may be necessary to run the vent pipe and air intake downwards. If this is to be done, the following rules must be fol- lowed.

• A condensate trap hose must be connected to both the air intake

pipe and the vent pipe at the lowest part of the horizontal run.

• The condensate drain trap must have a trap of a minimum of six

inches.

• The total vertical downward distance must not exceed sixteen

feet.

• The condensate drain hose must be connected to a condensate

drain pump, a open or vented drain or into the condensate drain

line from the furnace.

• The condensate drain lines must not pass through unconditioned

spaces where the temperature may fall below freezing.

Outdoor Combustion Air

Combustion Air Intake/Vent Connections

This installation requires combustion air to be brought in from outdoors. This requires a properly sized pipe (Shown in Figure 35) that will bring air in from the outdoors to the furnace combustion air intake collar on the burner box. The second pipe (Shown in Figure 35) is the furnace vent pipe.

NOTICE

An optional plastic birdscreen is shipped in the loose parts bag with every furnace. This may be installed in the intake collar to prevent any small objects from entering the furnace.

• The condensate drain line must be primed at the initial start-up

prior to the start of heating season.

COMBUSTION AIR SUPPLY

All installations must comply with Section 5.3, Air for Combustion and Ventilation of the National Fuel Gas Code, ANSI Z223.1 or Sections 7.2, 7.3 or 7.4 of CAN/CGA B149.1 or .2 Installation Code - latest edi- tions.

This furnace is certified to be installed with one of three possible com- bustion air intake configurations.

1.OUTDOOR COMBUSTION AIR: This is a direct vent configuration where the combustion air is supplied through a PVC or ABS pipe that is connected to the PVC coupling attached to the furnace and is terminated in the same atmospheric zone as the vent. This type of installation is approved on all models. Refer to Figure 35.

2.AMBIENT COMBUSTION AIR: Combustion air is supplied from the area surrounding the furnace through openings in the furnace casing. The combustion air and the vent pipes are not terminated in the same atmospheric zone. Refer to Figure 30 for vent termina- tions. Refer to "Ambient Combustion Air Supply" for proper installa- tion. Refer to Figure 36.

3.VENTILATED COMBUSTION AIR: Combustion air is supplied through a PVC or ABS pipe that is connected to the PVC coupling attached to the burner box and is terminated in a ventilated attic or crawl space. The combustion air and the vent pipes are not termi- nated in the same atmospheric zone. Refer to Figure 38 for attic and crawl space termination. Only the combustion air intake may terminate in the attic. The vent must terminate outside.

FIGURE 36: Direct Vent Air Intake Connection and Vent Connection

The combustion air intake pipe should be located either through the wall (horizontal or side vent) or through the roof (vertical vent). Care should be taken to locate side vented systems where trees or shrubs will not block or restrict supply air from entering the terminal.

Also, the terminal assembly should be located as far as possible from a swimming pool or a location where swimming pool chemicals might be stored. Be sure the terminal assembly follows the outdoor clearances listed in Section #1 “Outdoor Air Contaminants.”

Ambient Combustion Air Supply

This type installation will draw the air required for combustion from within the space surrounding the appliance and from areas or rooms adjacent to the space surrounding the appliance. This may be from within the space in a non-confined location or it may be brought into the furnace area from outdoors through permanent openings or ducts. It is not piped directly into the furnace. A single, properly sized pipe from the furnace vent connector to the outdoors must be provided. It is recom- mended that the supplied intake coupling and 18” (46 cm) of pipe be attached to the furnace to prevent accidental blockage of the combus- tion air intake.
