Lochinvar 400-801 Provide clearances, Outdoor vent / air intake location, Flooring and foundation

Provide clearances:

Clearances from combustible materials

1.Hot water pipes—at least 1/4" (6 mm) from combustible materials.

2.Jacket—minimum of 0" from right side and 14" from rear side for proximity from combustible materials.

3.Vent—minimum of 1" from combustible materials.

Clearances for service access

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

Recommended service clearances

Front: 30" (762mm)

Top: 24" (610mm)

Left side: 24" (610mm)

Rear: 24" (610mm)

Outdoor vent / air intake location:

￿WARNING The flue products discharged from the flue outlet on the outdoor vent may be

very hot. Avoid touching or making other direct contact with the flue gases or the vent termination. These components are hot and direct contact can result in burns.

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 or 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" clearance to 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 the unit at least 10 feet (3.05m) away from any forced inlet.

Multiple unit outdoor installations require 24" (1.22m) 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.

Flooring and foundation

Flooring

The Outdoor Knight XL 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.
