Part 2 - Before You Start
B. How the Heater Operates
Modulating Condensing Technology is an intelligent system
that delivers highly ecient water heating, maximizing
eciency by measuring the data parameters of your water
heating system. Some of its features are:
Stainless Steel Water Storage Tank
The stainless steel water storage tank has a combustion
chamber submerged into the tank water. When the water heater
is red, combustion gases heat the combustion chamber walls,
transferring heat directly into the surrounding water. These hot
gases are blown into secondary heat exchanger coils, where
more heat from these gases is transferred into the water.
Modulating Combustion System
The control monitors the water heating system and
temperatures, regulating burner output during operation to
match system demand. This increase in eciency allows for
substantial fuel savings.
Gas Valve
The gas valve senses suction from the blower, allowing gas to
ow only if the gas valve is energized and combustion air is
owing.
Upper Outlet Tank Sensor
This sensor monitors the upper portion water temperature
(outlet) of the water heater. The control module adjusts burner
ring rate so the outlet water temperature meets the set point.
Lower Inlet Tank Sensor
This sensor monitors the lower portion water temperature (inlet)
of the water heater. The control module reduces or increases
input, depending on how close the inlet water temperature is to
the outlet water temperature set point.
Control
The integrated control system monitors upper and lower water
temperature and adjusts fan speed to regulate the heater’s
energy output. This allows the unit to deliver the required
amount of heated energy and nothing more.
Burner
Constructed of high grade stainless steel, the burner uses pre-
mixed air and gas and provides a wide range of ring rates.
Condensate Drain System
This is a condensing high eciency water heater with a
condensate removal system. Condensate is nothing more than
water vapor derived from combustion products, similar to that
of an automobile when it is initially started. It is very important
that the condensate line slopes away from the water heater and
down to a suitable inside drain.
If the condensate outlet on the heater is lower than the drain, us

a condensate removal pump (Part # 554200, available from
HTP). In addition, local authorities may require an additional
condensate neutralizer to neutralize the condensate.
Condensate neutralizers are made up of lime crystals, marble,
or phosphate chips. Neutralizers can be installed in the eld
by the installer and purchased from HTP (p/n 7450P-212).
It is also very important not to expose the condensate line to
freezing temperatures or any type of blockage. Plastic tubing
must be the only material used for the condensate line. Steel,
brass, copper, or other materials will be subject to corrosion
or deterioration. A second vent may be necessary to prevent
condensate line vacuum lock on a long horizontal run. Also,
an increase in pipe size may be necessary to allow condensate
to drain properly. Support of the condensate line may be
necessary to avoid blockage of the condensate ow.
Spark Ignition
The burner ame is ignited by applying high voltage to the
system spark electrode. This causes a spark from electrode to
ground.
Outdoor Sensor
Monitors outdoor temperature and adjusts set point to
provide greater eciency.

COLD WEATHER HANDLING - If the water heater has

o
F) before
installation, handle with care until the components come to
room temperature. Failure to do so could result in damage to
the water heater.
Carefully consider installation when determining heater
location. Please read the entire manual before attempting
installation. Failure to properly take factors such as heater
venting, piping, condensate removal, and wiring into account
before installation could result in wasted time, money, and
possible property damage and personal injury.
