VERTICAL VENT APPLICATIONS AND

TERMINATION

Roof mounted vertical terminals may be field fabricated. Standard PVC/ SRD fittings may be used. If installing a vertical venting system through any unconditioned space such as an attic or crawl space it must be insulated.

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

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

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

4.Termination should be located where it cannot be damaged, plugged or restricted by tree limbs, leaves and branches.

5.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).

VENTING MULTIPLE UNITS

Only the sealed combustion system can be used for installations requir- ing more than one furnace in a structure. A separate sealed combustion air pipe and a separate vent pipe must be installed for each furnace. Do not connect more than one furnace to a combustion air pipe or a vent pipe. The combustion air and vent termination must be located as shown in Figures 23 or 24.

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 sealed combustion air configuration where the 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 the same atmospheric zone as the vent. This type of installation is approved on all models. Refer to Figures 25 & 27.

2.AMBIENT COMBUSTION AIR: Combustion air is supplied from the area surrounding the furnace through the combustion air pipe in the furnace casing. The combustion air and the vent pipes are not terminated in the same atmospheric zone. Refer to Figures 19 & 26 for vent terminations. Refer to “AMBIENT COMBUSTION AIR SUPPLY” and “VENT AND SUPPLY OUTSIDE AIR SAFETY CHECK PROCEDURE” for proper installation.

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 28 for crawl space and attic termination. Only the combustion air intake may terminate in the attic. The vent must terminate outside.

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 Figures 31, 33, or 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 Figures 31, 33 or 35) is the furnace vent pipe.
