HOW THE PHOENIX EVOLUTION OPERATES

PART 2: HOW THE PHOENIX EVOLUTION OPERATES

The Phoenix Evolution with Total System Control is truly a revolutionary System that provides High
Efficiency Heating and Domestic Hot Water from one appliance. The Total System Control manages
your system needs to assure maximum comfort and efficient operation. Listed below is a brief expla-
nation of the major system components.

1. Stainless Steel Water Storage Tank

The Storage Tank is constructed of 316L Stainless Steel to provide maximum corrosion resistance.
The water blown foam insulation and plastic jacket provides superior insulation allowing no more
than a ½ degree heat loss per hour.

2. High Efficiency Heat Exchanger

The Phoenix Evolution’s highly efficient 90/10 copper nickel Heat Exchanger provides a direct
transfer of energy from the combustion gases into the domestic water. The hot gases travel from
the primary circuit to heat the combustion walls which then transfers the heat directly into the
water. The secondary circuit then transfers the last bit of energy to the bottom of the tank where
the hot gases are also converted to a water vapor giving the Phoenix Evolution a combustion
efficiency of 98% with a thermal efficiency of up to 96%.

3. Modulating Combustion System

The Modulating combustion system is designed to modulate and regulate the firing rate based on
the heat demand. The Total System Control monitors the operation of the tank and system
parameters controlling the firing rate of the burner. This provides only the required energy needed
to satisfy the needs of both the Domestic Heating and Central Hot Water System.

4. Total System Control

Total System Control will automatically manage the needs of both the Central Heating System and
The Domestic Hot Water System. This is accomplished through sensors that provide feedback to
the control that monitors inputs such as - Outdoor Temperature –Tank Temperature- Heating
Module Outlet Temperature, thus allowing accurate control over the entire system. You may
choose to use the factory default settings or you can re-program the control system parameters
to help provide system design flexibility.

5. Hydronic Heating Module

The Hydronic Heating Module is connected to the Storage Tank through two dip tubes, The first
dip tube draws heated water from the top of the storage tank and is circulated through a Brazed
Plate Heat Exchanger that transfers the stored energy from the storage tank to the hydronic side
of the plate. Once the energy is transferred, it returns through the second dip tube to a lower
section of the storage tank to continue circulating. A Stainless Steel Circulator Pump modulates
the output to vary the flow through the Brazed Plate Heat Exchanger in order to meet the domestic
hot water demand and central hot water demand. An outlet sensor will provide feedback to the
control to assure accurate temperature control.

6. Venting System

This appliance vents in plastic pipe. Use only approved material when venting as outlined in the
venting section of this manual. Vent size can vary from 2” to 3” depending on the appliance input
rate. The venting system requires an intake and exhaust vent and special attention should be taken
when selecting a vent location. Vents can be run either horizontal or vertical depending on your
system design. Supporting the vents is required as shown in the Venting Details Part 8.

7. Burner

The burner is constructed of high grade stainless steel construction and uses pre-mixed air and gas
to provide a wide range of firing rates.

8. Condensate Drain Connection

This is a high efficiency condensing appliance, therefore, this unit has a condensate removal system.
