Installation & Operation Manual
The Knight Wall Hung Fire Tube 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 Hung Fire Tube 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.
• Debris left from existing piping, if not flushed and
cleaned with an appropriate cleaner.
6. Check around the boiler for any potential air
contaminants that could risk corrosion to the boiler or
the boiler combustion air supply (see Table 1B on page
10). Prevent combustion air contamination. Remove
any of these contaminants from the boiler area.

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.
Do not install the appliance where the
relative humidity may exceed 93%.
Do not install the appliance where
condensation may form on the inside
or outside of the appliance, or where
condensation may fall onto the appliance.
Failure to install the appliance indoors
could result in severe personal injury,
death, or substantial property damage.
Closet and alcove installations
This appliance requires a special venting
system. If using PVC the vent connection
to the appliance must be made with the
starter CPVC pipe section provided with
the appliance. The field provided vent
fittings must be cemented to the CPVC
pipe section. Use only the vent materials,
primer and cement specified in this
manual to make the vent connections.
Failure to follow this warning could result
in fire, personal injury, or death.
For closet and alcove installations CPVC,
polypropylene or stainless steel vent
material must be used. The ventilating air
openings shown in FIG. 1-1 are required
for closet installations. Failure to follow
this warning could result in fire, personal
injury, or death.

Determine boiler location
A closet is any room the boiler is installed in which the room
volume is less than the room volume listed in the table below.
An alcove is any room which meets the criteria for a closet,
but it does not have a door.
DO NOT install units in rooms or
environments that contain corrosive
contaminants (see Table 1B on page 10).
Failure to comply could result in severe
personal injury, death, or substantial
property damage.

WARNING
Example: Room dimensions = 4 feet long, 3 feet wide,
and 8 foot ceiling = 4 x 3 x 8 = 96 cubic feet. This would be
considered a closet for a WHN286 model.
