5 Flexible Options for Direct-Venting up to 100 Feet!
Placement of units within a building will never be a problem with KNIGHT.
It permits up to 100 feet of air intake and 100 feet of exhaust vent with
3" PVC, CPVC, polypropylene or stainless steel pipe. Three Wall-Mounted
KNIGHT
models (WBN 51 -106) also permit intake and vent runs up to 40
feet using 2" pipe.

NEW!
Multiple Sized Boiler Cascade
Control
KNIGHTS of one or more sizes can be combined
into a single cascade to maximize turndown and
meet minimum demands.
* Internal Cascading Sequencer
with Multiple Programmable
System Efficiency Optimizers
Fine-tune installations using Lead-Lag or
Efficiency Optimization Cascade features.
* Controls up to Three
Setpoint Temperatures
Allows three different temperature inputs to
be controlled. Boiler can be run at the lowest
temperature demand for optimal efficiency.
* Outdoor Reset for Each Temp Loop
The boiler setpoint temperature responds to changes
in outdoor air temperature. Outdoor temperature
monitor guides the reset schedule to meet the load.
Night Setback
Program a heating loop temperature setback for
any time of the day, each day of the week.
Domestic Hot Water
Prioritization w/Pump Control
On DHW call, SMART SYSTEM overrides the
outdoor reset and starts the DHW pump to the
indirect water heater alternating to meet both
heating and hot water demands.
* DHW Night Setback
Resets DHW setpoint to save water-heating
energy during times of low or no usage.
* DHW Max Firing Rate
Allows you to limit the maximum percentage of
firing rate when in DHW mode.
* Separately Adjustable
SH/DHW Mode Switching Times
Allows controls to be tailored to meet system
demand. Design system setup for flexibility.
Indirect Water Heater
Zone Pump Control
All boilers in cascade can be used to meet DHW
demand as well as satisfy building load.
System & Boiler Pump Controls
Provides power to system and boiler pumps on
a call for heat. Programmable post purge allows
pumps to operate after a call has been satisfied.
Option for Continuous System Pump Operation.
* Pump Relay with
Freeze Protection
Parameters adjustable by installer for flexibility in
low-temperature applications.
* Installer Access to
BMS and Ramp Delay Settings
Set up or change these parameters through the control
itself on the front of the boiler; no PC software required.
Low-Water Flow Indicator
Uses temperature differential to protect
against low flow in heat exchanger by reducing
modulation or forcing boiler shutdown.
Password Security
Allows only qualified personnel to access
parameters
* Product Service Indicator
Program reminders for cycle count, operation
hours or last service. Installer's name and
number may be displayed.
Optional Modbus Capability
Allows boiler communication through Modbus
protocol. Simplifies BMS/boiler interface for
status monitoring.
0-10V Building Management
System (BMS) Control Input
BMS-driven input for modulation rate or
temperature control.
0-10V Cascade Setpoint
and Modulation Control
BMS-driven input for modulation rate or
temperature control of cascade.
0-10V Heat Demand Input
Enables thermostat or a 0-10V signal to initiate
a call for heat. Gives the BMS options on how to
enable boiler or cascade.
0-10V Boiler Rate Output
Signal output of modulation rate allows BMS to
monitor boiler firing rate.
0-10V Pump Signal Input
Input from variable speed system pump allows
faster reaction to changes of flow in system,
reducing possibility of temperature over-shoot
and cycling.
0-10V Signal to Control Variable
Speed Boiler Pump
Allows control to maintain a higher
T at low
firing rates and reduces boiler flow when it
responds to lower flow rates in the system loop.
Dial in System Performance
*An optional concentric vent kit is sold separately to allow a single penetration for both combustion air and vent pipes.
