Condensate Collection System
This boiler is a high efficiency appliance and will produce condensate.
The condensate collection system has a float switch 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.
Outdoor Sensor
Monitors outdoor temperature and adjusts unit set point to provide
greater efficiency.
0-10 Volt Input / 4-20 mA Input (with Optional Analog Clip-In
Board, part # 3319457)
Allows the installer to connect a BMS (Building Management System)
to control the boiler.
Condensate Trap and Air Pressure Switch
The condensate trap and air pressure switch prevent condensate
and heat exchanger exhaust backing up into the cabinet.
Pump Service Mode
Allows manual operation of pumps to commission system and check
pump operation.
Internal By-Pass Valve
Protects the boiler from damage in low flow conditions.
Internal ECM Pump
The internal ECM Pump uses less electricity than standard pumps,
providing high performance operation.
B. Optional Equipment
Optional equipment available from HTP (and Part #):
• Indirect Sensor (7250P-325)
• System Sensor (7250P-324)
• 3” PVC Concentric Vent Kit (KGAVT0601CVT)
• 3” Stainless Steel Vent Termination Kit (V1000)
• 3” Polypro Vent Kit (8400P-001)
• 3” Polypro Pipe
(33’ length # 8400P-002, 49.5’ length # 8400P-003)
• Condensate Neutralizer (7450P-212)
• Condensate Removal Pump (554200)
NOTE: When using an optional system sensor, pipe insulation
must be wrapped around it to improve temperature measurement
accuracy and increase overall system efficiency.
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.
CAUTION
Part 3 - Prepare the Boiler for Installation
WARNING
!
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
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 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.
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
WARNING
!
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.
Circulators suitable for DHW applications must be used.
Failure to take precautions could result in property damage, severe
personal injury, or death.

2. Check for nearby connections to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
• Condensate drain
3. Check area around boiler. Remove any combustible materials,
gasoline, and other flammable liquids.
CAUTION
The service life of the boiler’s exposed metallic surfaces, such as
the casing, as well as internal surfaces, such as the heat exchanger,
are directly influenced by proximity to damp and salty marine
environments. In such areas higher concentration levels of
chlorides from sea spray coupled with relative humidity can lead
to degradation of boiler components. In these environments,
boilers must not be installed using direct vent systems which draw
outdoor air for combustion. Such boilers must be installed using
room air for combustion. Indoor air will have a much lower relative
humidity, and hence potential corrosion will be minimized.
Failure of the boiler or components due to incorrect operating
conditions IS NOT covered by product warranty.
