Venting and Combustion Air Installation

Venting Option - Direct Vent / Horizontal

In this vent application the PERFORMANCE PLUS is vented horizontally through a wall using only approved 3-inch stainless steel vent material and using outside air for combustion.

The installer should consider the following when choosing this vent option:

a.The vent system should contain a con- densate trap located near the unit as shown in Figs. 22, 22A& 22B, page 34.

b.The vent system must pitch back to the unit 1/4 inch per foot.

BEST PRACTICE

Although the vent system is allowed to pitch away from the unit, it is recom- mended that the vent system pitches toward the unit with a condensate drain installed as close to the unit as possible. Opting to pitch the vent system away poses potential damage to the building exterior or to the surrounding landscape and/or potential risks of icing if conden- sate is formed.

c.Penetration at the wall requires a thimble.

d.Clearance to combustibles must be maintained per the vent manufacturer’s requirements. Refer to the vent manu- facturer’s installation instructions for additional details.

NOTICE

Maintain a minimum 2-inch clearance to combustible wall and 1-inch clearance to non-combustible in the absence of a manufacturer’s recommended clearance when penetrating a sidewall.

e.For a zero clearance concentric termina- tion of the vent and combustion air refer to the Horizontal Concentric, Horizontal Single Wall Vent or Horizontal Wall Thimble Kits.

There are two methods available for Direct Venting - Horizontal:

Separate: The vent and the combustion air inlet are run together and exit the structure sep- arately with different terminations. See Fig. 23, page 35.

NOTICE

The combustion air inlet and the vent termination must reside in the same pressure zone area of the building for proper operation of the appliance.

Combination: The vent and combustion air ter- minate at a single concentric point using the Horizontal Concentric, Horizontal Single Wall Vent or Horizontal Wall Thimble Kit. See Figs. 22, 22A & 22B page 34.

Horizontal Wall Thimble Kit

- Requires a 5 1/2 inch x 5 1/2 inch penetra- tion through any type of wall.

-Allows zero clearance at the wall penetration.

-Maximum wall thickness is 11 inches.

-The use of a termination elbow for the venting system is not recommended when using the Horizontal Wall Thimble Kit.

BEST PRACTICES

To prevent potential nuisance lock-outs or flue gas recirculation it is recom- mended to terminate the vent with a hor- izontal termination tee or side discharge vent hood.
