2.Vent pipes—minimum of 14" (356mm) from the rear and 0" on the right side from combustible materials.

Clearances for service access

1.If you do not provide the minimum clearances, it may not be possible to service the boiler without removing it from the space.

Recommended service clearances:

Front

-

24" (610mm)

Top

Outdoor vent / air intake location

Flooring and foundation

Flooring

The Outdoor Knight is approved for installation on combustible flooring.

￿ WARNING

Do not install the boiler on carpeting even if

 

foundation is used. Fire can result, causing

 

severe personal injury, death, or substantial

 

property damage.

Under no circumstances is the manufacturer to be held responsible for water damage in connection with this appliance, or any of its components. If flooding is possible, elevate the boiler sufficiently to prevent water from reaching the boiler.

Prevent combustion air contamination

Do not install unit in locations that can allow contamination of combustion air. Refer to Table 1A for products and areas which may cause contaminated combustion air.

￿WARNING

The flue products discharged from the flue outlet on the outdoor vent may be very hot. Avoid touching or other direct contact with the flue gases or the vent termination assembly. These components are hot and direct contact can result in burns.

Table 1A Corrosive Contaminants and Sources

Products to avoid:

Spray cans containing chloro/fluorocarbons

Permanent wave solutions

Chlorinated waxes/cleaners

To prevent recirculation of the flue products into the combustion air inlet, follow all instructions in this section.

Flue gas condensate can condense on exterior walls or on the vent. 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.

Maintain a minimum of 24" (610mm) clearance to the side of the air inlet.

Locate the outdoor vent termination at least 48" (1.22m) below and 48" (1.22m) horizontally from any window, door, walkway or gravity air intake.

Locate outdoor unit at least 10 feet (3.05m) away from any forced air inlet.

Multiple outdoor unit installations require 24" (.61m) clearance between each vent termination.

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.
