VENT SYSTEM

This furnace is certified to be installed with one of two possible vent configurations.

1.Horizontal vent system. This vent system can be installed com- pletely horizontal or combinations of horizontal, vertical, or offset using elbows.

2.Vertical vent system. This vent system can be installed completely vertical or a combination of horizontal, vertical, or offset using elbows.

HORIZONTAL VENT APPLICATIONS AND TERMINATION

When selecting the location for a horizontal combustion air / vent termi- nation, the following should be considered:

1.Observe all clearances listed in vent clearances in these instruc- tions.

2.Termination should be positioned where vent vapors will not dam- age plants or shrubs or air conditioning equipment.

3.Termination should be located where it will not be affected by wind gusts, light snow, airborne leaves or allow recirculation of flue gases.

4.Termination should be located where it will not be damaged or exposed to flying stones, balls, etc.

5.Termination should be positioned where vent vapors are not objec- tionable.

6.Horizontal portions of the vent system must slope upwards and be supported to prevent sagging. The vent system may be supported by the use of clamps or hangers secured to a permanent part of the structure every 4 ft. (1.22 m).

7.Sealed combustion air systems must be installed so the vent and the combustion air pipes terminate in the same atmospheric zone. Refer to Figures 19, 20, & 21.

DOWNFLOW VENT ASSEMBLY

1.Place the 2” (5.08 cm) 45° PVC street elbow on the vent connec- tion shown in Figure 18.

2.Place the 2” (5.08 cm) PVC WYE (“Y”) assembly on the 2” (5.08 cm) 45° PVC street elbow as shown in Figure 18.

3.Locate the rubber condensate hose in front of the blower access panel.

4.Slide the hose through the hole in the top cover, and insert the hose on to the barbed fitting on the bottom of the 2” (5.08 cm) PVC WYE (“Y”) assembly as shown in Figure 18.
