Outdoor Knight Boiler Installation & Operation Manual

1 Determine boiler location

Installation must comply with:

Local, state, provincial, and national codes, laws, regulations, and ordinances.

National Fuel Gas Code, ANSI Z223.1 – latest edition.

Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1, when required.

National Electrical Code.

NOTICE

The Outdoor Knight gas manifold and

controls met safe lighting and other

 

 

performance criteria when the boiler

 

underwent tests specified in ANSI Z21.13

 

– latest edition.

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.

The outdoor unit must not be installed in an area that is enclosed by walls or a fence that will block free wind movement around the unit. Free movement of wind around the outdoor unit is required to carry away the flue products and provide combustion

￿WARNING

CAUTION

Outdoor models must be installed outdoors only and must use the outdoor vent kit assembly supplied by the manufacturer. Personal injury or product damage may result if any other cap 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 situation.

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.

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

- Do not install the outdoor unit under a deck.

-Do not install an outdoor unit in a well, stairwell, alcove, courtyard or other recessed area.

-Do not install outdoor units on stack frames.

Before locating the boiler, check:

1.Check for nearby connection to:

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 of 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 pressure-treated wood platform.

8

Failure to comply with the above could result in severe personal injury, death or substantial property damage.

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

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

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

￿WARNING Failure to keep the 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 cracks from hard water deposits.

Incorrectly-sized expansion tank.

Lack of freeze protection in boiler water causing system and boiler to freeze and leak.
