Flue Sensor
Monitors flue temperature and adjusts firing rate.
Temperature and Pressure Gauge
Allows the user to monitor system temperature and pressure.
Electrical field connections with terminal strips
The electrical cover allows easy access to the clearly marked
line voltage and low voltage terminal strips to facilitate wiring
the boiler.
Condensate Collection System
This boiler is a high efficiency appliance and will produce
condensate. The condensate collection system has a float
which monitors condensate level and prevents condensate
from backing up into the combustion system. Inside the
collection system is a built in trap which seals the combustion
system from the connected drain. This condensate should be
neutralized to avoid damage to the drainage system or piping.
Flow Protection
The supplied flow switch is designed to protect the boiler
during low flow conditions. The boiler control also monitors
flow through the heat exchanger by monitoring the return
and supply sensors and will shut down the burner before
overheating occurs.
0-10 Volt Input
Allows the installer to connect a BMS (Building Management
System) to control the boiler.
Condensate Flue Check System
The check system prevents heat exchanger exhaust from
backing up into the cabinet.
Pump Service Mode
Allows manual operation of pumps to commission system and
check pump operation.

Part 3 - Prepare the Boiler
COLD WEATHER HANDLING
- If the boiler has been stored in a
very cold location (BELOW 0
o
F) before installation, handle with
care until the components come to room temperature. Failure
to do so could result in damage to the boiler.
Carefully consider installation when determining boiler location.
Please read the entire manual before attempting installation.
Failure to properly take factors such as boiler venting, piping,
condensate removal, and wiring into account before installation
could result in wasted time, money, and possible property
damage and personal injury.
This boiler is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by
warranty. Failure to install the boiler indoors could result in
property damage, severe personal injury, or death.
A. Locating the Boiler
1. Installation Area (Mechanical Room) Operating Conditions
•
Ensure ambient temperatures are higher than 32
o
F / 0
o
C
and lower than 104
o
F / 40
o
C
•
Prevent the air from becoming contaminated by the
products, places, and conditions listed in this manual
•
Avoid continuously high levels of humidity
•
Never close existing ventilation openings
•
Ensure a minimum 1” clearance around hot water and
exhaust vent pipes
•
NOTE: To prevent condensing in the fan, it is recommended
to avoid prolonged exposure to temperatures below 45
o
F
Incorrect ambient conditions can lead to damage to the
heating system and put safe operation at risk. Ensure that the
installation location adheres to the information included in this
manual. Failure to do so could result in property damage, serious
personal injury, or death. Failure of boiler or components due
to incorrect operating conditions IS NOT covered by product
warranty.
This boiler has a condensate disposal system that may freeze
if exposed to sustained temperatures below 32
o
F. Precautions
should be taken to protect the condensate trap and drain lines
from sustained freezing conditions. Failure to take precautions
could result in property damage, severe personal injury, or
death.
Remove all sides of the shipping crate to allow the boiler to be
moved into its installation location. The boiler is also equipped
with leveling feet that can be used to level the boiler properly on
an uneven location surface. If surface flooring is rough, take care
when moving the boiler into position, as catching the leveling
feet could damage the boiler.
This boiler must be installed upright in the vertical position as
described in this manual. DO NOT attempt to install this boiler
in any other orientation. Doing so will result in improper boiler
operation and property damage, and could result in serious
personal injury or death.
