2. Outdoor installation venting

NOTICE

Before installing a venting system, follow

all venting clearances and requirements

 

 

found in the Venting, General Information

 

section, page 16.

 

Only install outdoor models outdoors

WARNING

and only use the vent caps supplied by

 

the appliance manufacturer. Personal

 

injury or product damage may result if

 

any other cap is used or if an outdoor

 

model is used indoors. Properly install all

 

covers, doors and jacket panels to ensure

 

proper operation and prevent a hazardous

 

condition.

Units are self-venting and can be used outdoors when installed with the optional outdoor caps. These caps mount directly to the unit and cover the flue outlet and combustion air inlet openings. No additional vent piping is required.

Combustion air supply must be free of contaminants (see Combustion and Ventilation Air, page 12). To prevent recirculation of the flue products into the combustion air inlet, follow all instructions in this section.

Outdoor vent/air inlet location

Keep venting areas free of obstructions. Keep area clean and free of combustible and flammable materials. Maintain a minimum clearance of 3'' (76mm) to combustible surfaces and 36" clearance to the rear of the unit for outdoor installations. To avoid a blocked air inlet or blocked flue condition, keep the air inlet, flue outlet and drain slot clear of snow, ice, leaves, debris, etc.

CAUTION

Do not install outdoor models directly on

the ground. You must install the outdoor

 

 

unit on a concrete, brick, block, or other

 

non-combustible pad.

 

 

Do not locate unit so that high winds

CAUTION

can deflect off of adjacent walls, buildings

 

 

or shrubbery causing

recirculation.

 

Recirculation of flue products may cause

 

operational problems, bad combustion or

 

damage to controls. Locate

unit at least

 

3 feet (0.91m) from any wall or vertical

 

surface to prevent wind conditions from

 

affecting performance.

 

Installation & Service Manual

NOTICE

Multiple outdoor unit installations require

48'' (1.22m) clearance between each vent

 

 

cap. Locate the outdoor cap at least 48''

 

(1.22m) below and 48'' (1.22m) horizontally

 

from any window, door, walkway or gravity

 

air intake.

 

Locate the unit at least 10 feet (3.05m) away

 

from any forced air inlet.

 

Locate the unit at least 3 feet (0.91m)

 

outside any overhang.

 

Clearances around outdoor installations can

 

change with time. Do not allow the growth

 

of trees, shrubs or other plants to obstruct

 

the proper operation of the outdoor vent

 

system.

 

A minimum of 3 feet must be maintained

CAUTION

at all times from outdoor air vent cap

 

surfaces to combustible construction and/or

 

materials.

 

Do not install in locations where rain from

CAUTION

building runoff drains will spill onto the

 

unit.
