General
 
venting 
This appliance requires a special venting 
system. Use only approved stainless steel, 
PVC, CPVC or polypropylene pipe and 
fittings listed in Tables 3D, 3E, and 3G for 
vent pipe, and fittings.  Failure to comply 
could result in severe personal injury, 
death, or substantial property damage.
Installation must comply with local 
requirements and with the National 
Fuel Gas Code, ANSI Z223.1 for U.S. 
installations or CSA B149.1 for Canadian 
installations.
Install vent and combustion air piping
 DANGER
The Knight wall mount boiler must be 
vented and supplied with combustion and 
ventilation air as described in this section.  
Ensure the vent and air piping and the 
combustion air supply comply with these 
instructions regarding vent system, air 
system, and combustion air quality.  See 
also Section 1 of this manual.
Inspect finished vent and air piping 
thoroughly to ensure all are airtight and 
comply with the instructions provided and 
with all requirements of applicable codes.
Failure to provide a properly installed vent 
and air system will cause severe personal 
injury or death.
 WARNING
 NOTICE
 WARNING
For closet and alcove installations, CPVC, 
polypropylene or stainless steel material 
MUST BE used in a closet/alcove structure.  
Failure to follow this warning could result 
in fire, personal injury, or death.
Air intake/vent connections
1.  Combustion Air Intake Connector (FIG. 3-6) - Used to 
 
provide combustion air directly to the unit from outdoors.  
 
A fitting is provided on the unit for final connection.  
 
Combustion air piping must be supported per guidelines 
 
listed in the National Mechanical Code, Section 305, Table 
 
305.4 or as local codes dictate.
2.  Vent Connector (FIG.'s 3-7 thru 3-9) -  Used to provide a 
 
passageway for conveying combustion gases to the 
 
outside.  A transition fitting is provided on the unit for 
 
final connection.  Vent piping must be supported per the 
 
National Building Code, Section 305, Table 305.4 or as 
 
local codes dictate.
The Knight wall mount boiler vent and air piping can be 
installed through the roof or through a sidewall.  Follow the 
procedures in this manual for the method chosen.  Refer to the 
information in this manual to determine acceptable vent and 
air piping length.
You may use any of the vent/air piping methods covered in 
this manual.  Do not attempt to install the Knight wall mount 
boiler using any other means.
You must also install air piping from outside to the boiler 
air intake adapter unless following the Optional Room 
Air instructions on page 18 of this manual.  The resultant 
installation is direct vent (sealed combustion).
 WARNING
DO NOT mix components from different 
systems.  The vent system could fail, 
causing leakage of flue products into the 
living space.  Mixing of venting materials 
will void the warranty and certification of 
the appliance.
 WARNING Do not connect any other appliance to 
the vent pipe or multiple boilers to a 
common vent pipe.  Failure to comply 
could result in severe personal injury, 
death, or substantial property damage.
Improper installation of venting systems 
may result in injury or death.
 CAUTION
Follow the instructions in Section 1, page 
11 of this manual when removing a boiler 
from an existing vent system.
