Installation and Service Manual

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 a minimum of 3" (76mm) clearance to the air inlet. 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.

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 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.

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.

Do not install in locations where rain from building runoff drains will spill onto the unit.

Flue gas condensate can freeze on exterior walls or on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition. Some discoloration to exterior building or unit surfaces can be expected. Adjacent brick or masonry surfaces should be protected with a rust resistant sheet metal plate.

The Outdoor Vent Kit

The optional outdoor vent kit is available from the appliance manufacturer. The outdoor kit part numbers are listed by unit size. See TABLE-D for kit numbers.

You can install the outdoor vent cap and combustion air inlet panel(s) on the unit (see Figures 15 and 16).
