•National Electrical Code.

NOTICE

The Outdoor Knight XL gas manifold

and controls met safe lighting and other

 

 

performance criteria when the boiler

 

underwent tests specified in ANSI Z21.13

 

– latest edition.

￿CAUTION

The unit must not be installed in an area that is enclosed by walls or a fence that will block free wind movement around the appliance. Free movement of wind around the outdoor unit is required to carry away the flue products and provide combustion air. The flue outlet/ combustion air inlet of an outdoor unit must not be installed closer than 10 feet from an inside corner of an L-shaped structure. Walls or enclosed fencing may cause eddy currents which can recirculate the flue products into the combustion

￿WARNING

Outdoormodelsmustbeinstalledoutdoors only and must use the outdoor vent assembly supplied by the manufacturer. Personal injury or product damage may result if any other venting is used or if an outdoor model is used indoors. All covers, doors and jacket panels must be properly installed to ensure proper operation and prevent a hazardous condition.

CAUTION

air inlet. Recirculation of flue products may cause operational problems, bad combustion or non-warrantable damage to controls.

Locate the unit at least 3 feet (0.91m) outside any overhang.

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

￿WARNING

This product contains a condensate management and disposal system that may be subject to freezing if exposed to sustained temperatures below 32°F. Precautions should be taken to protect the condensate trap and drain lines during extended periods of outdoor temperatures below 32°F.

￿WARNING

Do not locate the unit so that water from sprinklers may spray directly onto it. Water may damage controls or other electrical components.

Do not install the unit under a deck.

Do not install the unit in a well, stairwell,

Before locating the boiler, check:

1.Check for nearby connection to:

•System water piping

•Gas supply piping

•Electrical power

2.- Keep venting areas free of obstructions.

- Keep area clean and free of combustible and flammable materials.

- To avoid a blocked air inlet or blocked flue condition, keep the outdoor air inlet and flue outlet clear or leaves, debris, etc.

CAUTION

Do not install outdoor models directly on

the ground. You must install the outdoor

 

 

unit on a level concrete, brick, block, or

 

pressure-treated wood platform.

alcove, courtyard or other recessed area.

Do not install outdoor units on stack frames. Failure to comply with the above may result in severe personal injury, death or substantial property damage.

3.Check area around the boiler. Remove any combustible materials, gasoline and other flammable liquids.

￿ WARNING

Failure to keep boiler area clear and free

of combustible materials, gasoline, and

 

other flammable liquids and vapors can

 

result in severe personal injury, death, or

 

substantial property damage.

4. If a new boiler will replace an existing boiler, check for

and correct system problems, such as:

• System leaks causing oxygen corrosion or heat exchanger

￿CAUTION

8

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.

cracks from hard water deposits.

• Incorrectly-sized expansion tank.

• This unit is not intended for installations where

temperatures may reach below 32°F (0°C). Exposure to

freezing temperatures will cause the system and boiler

to freeze and leak.
