Installation & Operation Manual

Determine boiler location
7
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.
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.
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.
Before locating the boiler, check:
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.
3.
Check area around the boiler. Remove any combustible
materials, gasoline and other flammable liquids.
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.
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.
Provide clearances:
Clearances from combustible materials
1. Hot water pipes—at least 1" 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.
Closet and alcove installations
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.
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.

NOTICE
WARNING
A closet is any room the boiler is installed in which is less than
79 cubic feet for WBN050 through WBN105 models,
104 cubic feet for WBN150 models, and 125 cubic feet for
WBN210 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.
