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.

PART 2: HOW THE PHOENIX OPERATES (CONTINUED)
9. Spark ignition
The burner flame is ignited by applying a high voltage to the system spark electrode. This causes a
spark from electrode to ground.
PART 3: PREPARE WATER HEATER LOCATION
A. INSTALLATIONS MUST COMPLY WITH:
• Local, state, provincial, and national codes, laws, regulations and ordinances.
• National Fuel Gas Code, ANSI Z223.1 – latest edition.

when undergoing tests specified in ANSI Z21.10.3 — latest edition.
n
WARNING
Failure to keep water heater area clear and free of combustible materials, gasoline and
other flammable liquids and vapors can result in severe personal injury, death or
substantial property damage.
6
PREPARATION
• System leaks.
• Incorrectly-sized expansion tank.
C. CLEARANCES FOR SERVICE ACCESS
1. If you do not provide minimum clearances, it
might not be possible to service the water heater
without removing it from the space. (See Fig. 31 at right)
D. RESIDENTIAL GARAGE INSTALLATION
Precautions
Take the following special precautions when installing the water heater in a residential garage. If the
heater is located in a residential garage, per ANSI Z223.1, paragraph 5.1.9:
• Place the Phoenix with a minimum of 18 inches above the floor of the garage to the bottom of the
heater to ensure the burner and ignition devices will be no less than 18 inches above the floor.
• Locate or protect the water heater so it cannot be damaged by a moving vehicle.
E. EXHAUST VENT AND INTAKE AIR VENT
The Phoenix requires a special vent system, designed for pressurized venting. Phoenix Water
Heaters are rated ANSI Z21.10.3 Category IV (pressurized vent, likely to condense in the vent).
You must also install air intake piping from outside to the water heater flue adaptor. The resultant
installation is categorized as direct vent (sealed combustion). Note: To prevent combustion air
contamination see Table 3-2 in this section for examples of areas to avoid when considering exhaust vent and intake air vent termination.

PREPARATION
each appliance remaining connected to the common venting system placed in operation, while the
other appliances remaining connected to the common venting system are not in operation.
a. Seal any unused openings in the common venting system.
b. Visually inspect the venting system for proper size and horizontal pitch and determine there is no
blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe
condition.
c. Insofar as is practical, close all building doors and windows and all doors between the space in
which the appliances remaining connected to the common venting system are located and other
spaces of the building. Turn on clothes dryers and any appliance not connected to the common
venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they
will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.
d. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust
thermostat so appliance will operate continuously.
e. Test for spillage after 5 minutes of main
burner operation. Use the flame of a match or
candle, or smoke from a cigarette, cigar, pipe,
or aerosol smoke (synthetic smoke).
f. After it has been determined that each
appliance remaining connected to the
common venting system properly vents when
tested as outlined herein, return doors,
windows, exhaust fans, fireplace dampers,
and any other gas-burning appliance to their
previous conditions of use.
g. Any improper operation of common venting
system should be corrected so the installation
conforms with the National Fuel Gas Code,
ANSI Z223.1 — latest edition. Correct by
resizing to approach the minimum size as
determined using the appropriate tables in
Table 13 of NFPA54 ANSI Z223.1 2006 of that
code. Canadian installations must comply
with B149.1 or B149.2 Installation Code.
H. WATER CHEMISTRY
1. Water Hardness
Water hardness is mainly due to the presence of calcium and magnesium salts dissolved in the
water. The concentration of these salts is expressed in mg/L, ppm or grains per gallon, as a
measure of relative hardness of water. Grains per gallon is the common reference measurement
used in the U.S. water heater industry. Hardness expresses as mg/L or ppm may be divided by
17.1 to convert to grains per gallon. Water may be classified as very soft, slightly hard, moderately
PART 3: PREPARE WATER HEATER LOCATION (CONTINUED)
n
CAUTION
Chemical imbalance of your water can cause severe damage to your water heater and
associated equipment and may also affect the efficiency. You may have to have your
water quality professionally analyzed to determine whether you need to install a water
softener. Failure of a heat exchanger due to lime scale build-up on the heating surface,
low pH or other chemical imbalance is non-warrantable.
9
PREPARATION
hard or hard based on its hardness number. The minerals in the water will precipitate out when
the water is heated and will cause accelerated lime and scale accumulation on a heat transfer
surface.
If the hardness of the water exceeds the maximum level of 25 grains per gallon, water should be
softened to a hardness level no lower than 5 grains per gallon. Water softened as low as 0 to 1
grain per gallon may be under-saturated with respect to calcium carbonate resulting in water that
is aggressive and corrosive.
2. pH of Water
pH is a measure of relative acidity, neutrality or alkalinity. Dissolved minerals and gases affect
water's pH. The pH scale ranges from 0 to 14. Water with a pH of 7.0 is considered neutral. Water
with a pH lower than 7 is considered acidic. Water with a pH higher than 7 is considered alkaline.
A neutral pH (around 7) is desirable for most potable water applications. Corrosion damage and
heater failures resulting from water pH levels of lower than 6 or higher than 8 are non-warrantable.
The ideal pH range for water used in a storage tank or a water heater system is 7.2 to 7.8.
3. Total Dissolved Solids
Total dissolved solids (TDS) is a measure of all minerals and solids that are dissolved in the water.
The concentration of total dissolved solids is usually expressed in parts per million (ppm) as
measured in a water sample. Water with a high TDS concentration will greatly accelerate lime and
scale formation in the hot water system. Most high TDS concentrations will precipitate out of the
water when heated. This can generate a scale accumulation on the heat transfer surface that will
greatly reduce the service life of a water heater. This scale accumulation can also impede the ability
of the heat exchanger to transfer heat into the water. A heat exchanger that is damaged or blocked
by lime/scale accumulation must be replaced. Failure of a water heater due to lime scale build up
on the heating surface is non-warrantable. The manufacturer of the water heater has no control
of the water quality, especially the TDS levels in your system. Total dissolved solids in excess of
2,000 ppm will accelerate lime and scale formation in the heat exchanger. Heat exchanger failure
due to total dissolved solids in excess of 2,000 ppm is a non-warrantable condition.
PART 3: PREPARE WATER HEATER LOCATION (CONTINUED)
CAUTION
Failure of a heat exchanger due to lime scale build-up on the heating surface, low pH
or other chemical imbalance is non-warrantable.
10
PREPARATION
I. TEMPERATURE AND PRESSURE RELIEF VALVE
A temperature and pressure relief valve is installed into the marked port (upper right). We recommend a WATTS 100XL-4 valve or equivalent for 100,000 BTU models, 40XL5 valve or equivalent for
130,000 BTU models or above input, meeting the requirements for relief valves for hot water heaters
as per ANSI Z21.22B by a nationally recognized lab that maintains a periodic inspection of production of such listed safety device. The pressure rating of the valve must not exceed the listed working pressure of this appliance, and must be rated to the proper BTU/hr capacity of the water heater.
Do not, under any circumstances, thread a cap or plug into the relief valve! Explosion, serious injury
or death may result! Relief valve piping must be directed to the floor or to an open drain, but not
connected directly. There must be a 6" space between the outlet of relief valve piping and drain or
floor. Do not hook up to drain system directly without an air space. The relief valve must be periodically checked for proper operation.
J. POTABLE EXPANSION TANK
A potable hot water expansion tank is required to offset the water expansion as the water is heated.
In most city plumbing systems, the water meter has a no return or back flow device built into the
system to prevent back flowing of water back into city mains. Some local codes require back flow
preventers on all incoming water supplies. The hot water expansion tank must be listed for potable
water use. The expansion tank should be located on the cold inlet piping close to the water heater.
n
CAUTION
The expansion tank must be suitable for hot potable water.
PART 3: PREPARE WATER HEATER LOCATION (CONTINUED)
n
WARNING
Following installation of the T & P Relief Valve, the valve lever MUST be operated AT
LEAST ONCE A YEAR by the water heater owner to ensure that waterways are clear.
Certain naturally occurring mineral deposits may adhere to the valve, blocking waterways,
rendering it inoperative. When the lever is operated, hot water will discharge if the
waterways are clear. PRECAUTIONS MUST BE TAKEN TO AVOID PERSONAL INJURY
FROM CONTACT WITH HOT WATER AND TO AVOID PROPERTY DAMAGE. BEFORE
operating lever, check to see that a discharge line is connected to the valve, directing the
flow of hot water from the valve to a proper place of disposal. If no water flows when the
lever is operated, replacement of the valve is required. TURN THE WATER HEATER “OFF”
AND CALL A PLUMBER IMMEDIATELY.
This device is designed for emergency safety relief and shall not be used as an operating
control. A relief valve functions, in an emergency, by discharging water. Therefore, it is
essential that a discharge line be piped from the valve in order to carry the overflow to a
safe place of disposal. The discharge line must be same size as the valve outlet must pitch
downward from the valve and terminate at least 6" above a drain where any discharge
will be clearly visible.
11
PREPARATION
K. WATER PIPING
The domestic water connections must be installed in accordance to all local and national plumbing
codes, or any applicable standard which prevails. The inlet and outlet ports of the Phoenix are 1" on
55 gallon models. On the 80 and 119 gallon models, the inlet and outlet ports are 1 ½". On the cold
inlet, (bottom left), install a 1" brass tee on 55 gallon models, or a 1 ½" tee on 80 and 119 gallon models. On the run of the 1" brass tee, install with pipe sealant compound, a 1" brass drain cock or equivalent. Into the branch of the 1" or a 1 ½" brass tee, install a copper male adapter to match your copper plumbing system. For convenience, you may install a sweat shut off valve and a union in the cold
inlet piping to ease servicing in the future. If there is a back flow preventer, or any type of a no return
valve in the system, then you must install an additional tee here for a suitable potable hot water
expansion tank. In the hot outlet, (top left), install a suitable adapter to match the copper tubing of
the plumbing system. A thermal trap or heat trap loop may be installed here, to provide additional
energy savings and prevent the thermal siphoning of domestic hot water.
L. AUXILIARY CONNECTIONS
The auxiliary connections are additional connections for an air handlers, plate exchangers or other
devices that supply hot water. These connections must be installed in accordance with all local and
national codes or any applicable standard that prevails. The auxiliary connections are 1" on all
Phoenix Models. Never use dielectric unions or galvanized steel fittings. Use only copper or brass
fittings. Teflon Sealant must be used on all connections. The top port is the supply outlet and the
bottom port is the return inlet.
n
WARNING
Never connect auxiliary connections to any system that uses glycol or other solutions
formulated for hydronic systems. These auxiliary connections are to be used only
in a
potable water system. Failure to follow this warning could result in death or serious
injury.
PART 3: PREPARE WATER HEATER LOCATION (CONTINUED)
