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.

•For Canada only: B149.1 Installation Code, CSA C22.1 Canadian Electrical Code Part 1 and any local codes.

NOTICE

The Knight wall mount boiler gas

manifold and controls met safe lighting

 

 

and other performance criteria when the

 

boiler underwent tests specified in ANSI

 

Z21.13 – latest edition.

Before locating the boiler, check:

￿WARNING

￿WARNING

This appliance is certified as an indoor appliance. Do not install the appliance outdoors or locate where the appliance will be exposed to freezing temperatures or to temperatures that exceed 100°F.

Failure to install the appliance indoors could result in severe personal injury, death, or substantial property damage.

This appliance requires a special venting system. The vent connection to the appliance is made of CPVC. Field supplied vent fittings must be cemented to the CPVC fitting on the boiler. Use only the vent materials, primer, and cement specified in the manual to make the vent connections. Failure to follow this warning could result in fire, personal injury, or death.

1. Check for nearby connection to:

• System water piping

• Venting connections

• Gas supply piping

• Electrical power

2. Locate the appliance so that if water connections should

leak, water damage will not occur. When such locations

cannot be avoided, it is recommended that a suitable

drain pan, adequately drained, be installed under the

appliance. The pan must not restrict combustion air

flow. Under no circumstances is the manufacturer to be

held responsible for water damage in connection with

this appliance, or any of its components.

Closet and alcove installations

A closet is any room the boiler is installed in which is less than 79 cubic feet for WBN051 through WBN106 models, 104 cubic feet for WBN151 models, and 125 cubic feet for WBN211 models.

An alcove is any room which meets the criteria for a closet with the exception that it does not have a door.

Example: Room dimensions = 4 feet long, 4 feet wide, and 9 foot ceiling = 4 x 4 x 9 = 144 cubic feet. This would be considered a closet for a Knight wall mount boiler.

3. Check area around the boiler. Remove any combustible

materials, gasoline and other flammable liquids.

Failure to keep boiler area clear and free ￿ WARNING of combustible materials, gasoline, and other flammable liquids and vapors can result in severe personal injury, death, or

substantial property damage.

￿WARNING

For closet and alcove installations as shown in FIG.’s 1-1 and 1-2, CPVC or stainless steel vent material must be used inside the structure. The two ventilating air openings shown in FIG. 1-1 are required for this arrangement. Failure to follow this warning could result in fire, personal injury, or death.

4. The Knight wall mount boiler must be installed so that gas control system components are protected from dripping or spraying water or rain during operation or service.

5. 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.

Provide clearances:

Clearances from combustible materials

1.Hot water pipes—at least 1/4" from combustible materials.

2.Vent pipe – at least 1" from combustible materials.

3.See FIG.’s 1-1 and 1-2 on page 8 for other clearance minimums.

Clearances for service access

1.See FIG.’s 1-1 and 1-2 on page 8 for recommended service clearances. If you do not provide the minimum clearances shown, it may not be possible to service the boiler without removing it from the space.
