HOW THE PHOENIX OPERATES
PART 2: HOW THE PHOENIX OPERATES
Phoenix Modulation Condensing Technology is an intelligent system that delivers highly efficient
water heating, while maximizing efficiency by measuring the Data Parameters of your water heating
system.
1. 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 fired, the combustion gases heat the combustion chamber walls,
transferring the heat directly into the surrounding water. The hot gases are blown into the secondary
heat exchanger coils, where even more heat is transferred into the water, wringing even more heat
from the gases.
2. Modulating Combustion System
Modulation during the water heating operation is based on the tank temperature. The control
monitors the system to regulate the output of the burner during operation to match the system
demand. This increase in efficiency allows for substantial fuel savings.
3. Gas Valve
The gas valve senses suction from the blower, allowing gas to flow only if the gas valve is energized
and combustion air is flowing.
4. Upper Supply Tank Sensor
This sensor monitors water heater upper portion water temperature (system supply). The control
module adjusts the burner firing rate so the outlet temperature is correct.
5. Lower Return Tank Sensor
This sensor monitors the lower portion of the water heater return water temperature (system return).
The control module reduces or increases the input, depending on how close the water temperature
is to the outlet water temperature set point.
6. Control
The integrated control system monitors the upper and lower water temperature and regulates the
fan speed to regulate the unit’s BTU output. This allows the unit to only deliver the amount of heated
energy required and nothing more!
7. Burner
Constructed of high grade stainless steel construction, the burner uses pre-mixed air and gas and
provides a wide range of firing rates.
8. Condensate drain connection
This is a condensing high efficiency appliance, therefore this unit has a condensate removal system.
Condensate is nothing more than water vapor, derived from the combustion products, similar to an
automobile when it is initially started. It is very important that the condensate line is sloped away
from the water heater and down to a suitable inside drain. If the condensate outlet on the Phoenix
is lower than the drain, you must use a condensate removal pump (kit p/n 554200 available from
Heat Transfer Products, Inc.) A condensate neutralizer, if required by local authorities can be made
up of lime crystals, marble or phosphate chips and will neutralize the condensate. This can be done
in the field by the installer or you may purchase one from Heat Transfer Products, Inc. (P/N N1100).
It is also very important that the condensate line is not exposed to freezing temperatures or any other
type of blockage. Plastic tubing must be the only material used for the condensate line. Steel, brass,
copper or others will be subject to corrosion or deterioration. A second vent may be necessary to
prevent condensate line vacuum lock if a long horizontal run is used. Also, an increase in pipe size
may be necessary to drain properly. Support of the condensation line may be necessary to avoid
blockage of the condensate flow.
