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.

• National Electrical Code.

• For Canada only: B149.1 or B149.2 Installation Code, CSA C22.1 Canadian Electrical Code Part 1
and any local codes.

B. BEFORE LOCATING THE PHOENIX

1. Check for nearby connection to:

• System water piping

• Venting connections

• Gas supply piping

• Electrical power

2. Check area around water heater. Remove any combustible materials, gasoline and other
flammable liquids.

3. The Phoenix gas control system components are protected from dripping or spraying water or rain
during operation or service.

4. If the Phoenix Water Heater is to replace an existing water heater, check for and correct any
existing system problems such as:

n

DANGER

Water temperature over 125 degrees F. can cause severe burns
instantly, or death from scalds. Children, disabled, and elderly are
at highest risk of being scalded. See instruction manual before
setting temperature at water heater. Feel water before bathing or
showering! Temperature limiting valves are available.

NOTICE

The Phoenix gas manifold and controls met safe lighting and other performance criteria
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

Intake and exhaust must terminate near each other and may be vented vertically through the roof or
through a side wall. The intake and exhuast venting methods are detailed in the Venting Section. Do
not attempt to install the Phoenix Water Heater using any other venting means. Be sure to locate the
Phoenix such that the air intake and exhaust vent piping can be routed through the building and prop­erly terminated outdoors. The air intake and exhaust vent piping lengths, routing and termination
method must all comply with the methods and limits given in the Venting section.

F. PREVENT COMBUSTION AIR CONTAMINATION

Install intake air piping for the Phoenix Water Heater as described in the Venting section. Do not ter­minate exhaust in locations that can allow contamination of intake air.

G. WHEN REMOVING A WATER HEATER FROM AN EXISTING COMMON VENT SYSTEM

At the time of removal of an existing gas water heater, the following steps shall be followed with

PART 3: PREPARE WATER HEATER LOCATION (CONTINUED)

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.

PREPARATION

PART 4: PREPARE WATER HEATER

A. ELECTRICAL CONNECTION

The Phoenix Water Heater must be wired to a 120 volt circuit by a qualified electrician. It is recom­mended that the Phoenix Water Heater be wired on its own circuit to minimize the possibility of cir­cuit failure due to outside causes. The Phoenix Water Heater requires a maximum of 6 amps at 120
volts in use.

To wire the Phoenix Water Heater

1. Remove the screws on each side of the cover of the Phoenix burner control, then tilt the cover up
and remover it from the back plate.

2. Following all local and national wiring codes; route the incoming power wiring through the
knockout near the lower right corner of the back plate of the Phoenix burner control from the rear
to the inside of the burner control.

NOTE: Some earlier versions of the back plate
may require drilling of the hole to increase its size
to ½” conduit trade size (7/8” diameter)

3. Connect the line power wire (usually black) to
the terminal marked 120V

4. Connect the neutral wire (usually white) to the
terminals marked Neut.

5. Connect the ground wire (usually green) to the
terminal marked GND

6. Place the cover back on the Phoenix burner
control and secure it with the screws you
removed

B. GAS CONNECTION

The gas supply shall have a maximum inlet pressure of
less than 14" water column (350 mm), ½ pound pres­sure (3.5 kPa), and a minimum of 3.5" water column. The
entire piping system, gas meter and regulator must be
sized properly to prevent pressure drop greater than

0.5" WC as stated in the National Fuel Gas Code. This

information is listed on the rating plate. It is very impor­tant that you are connected to the type of gas as noted
on the rating plate. "LP" for liquefied petroleum, propane
gas or, "Nat" natural or city gas. All gas connections

WARNING

It is of extreme importance that this unit be properly grounded. It is very important that the
building system ground is inspected by a qualified electrician, prior to making this connection.
It is very important that the electrical power is only turned on when the Phoenix is completely
filled with cold water.

must be approved by the local gas supplier, or utility in addition to the governing authority, prior to
turning the gas supply on. Do not remove this adaptor! It is mandatory that this fitting is used for

connection to a field fabricated drip leg as shown in the illustration at right per the National Fuel
Gas Code. You must ensure that the entire gas line to the connection at the Phoenix Water Heater is

no smaller than ¾". Once all the inspections have been performed, the piping must be leak tested.
If the leak test requirement is a higher test pressure than the maximum gas inlet pressure, you must
isolate the Phoenix from the gas line to continue leak testing. In order to do this, you must turn off
the factory and field-installed gas cocks. This will minimize the possibility of damaging the Phoenix
gas valve. Failure to do so may damage the gas valve. In the event the gas valve is exposed to a
pressure greater than ½ PSI, 14" water column, the gas valve must be replaced. Never use an open
flame (match, lighter, etc.) to check gas connections.

C. GAS PIPING

1. Run the gas supply line in accordance with all applicable codes.

2. Locate and install manual shutoff valves in accordance with state and local requirements.

D. GAS TABLE

Refer to the below table to size the supply piping to minimize pressure drop between meter or
regulator and unit.

Maximum Capacity of Pipe in Cubic Feet of Gas per Hour for Gas Pressures of 0.5 psi or Less and a
Pressure Drop of 0.3 Inch water Column

Gas Table

It is recommended that a soapy solution be used to detect leaks. Bubbles will appear on the pipe to
indicate a leak is present. The gas piping must be sized for the proper flow and length of pipe, to avoid
excessive pressure drop. Both the gas meter and the gas regulator must be properly sized for the total
gas load. If you experience a pressure drop greater than 1" WC, the meter, regulator or gas line is
undersized or in need of service. You can attach a manometer to the incoming gas drip leg, by
removing the cap and installing the manometer. The gas pressure must remain between 3.5" WC and
14" WC during stand-by (static) mode and while in operating (dynamic) mode at full output. If an in-

line regulator is used, it must be a minimum of 10 feet from the Phoenix. It is very important that
the gas line is properly purged by the gas supplier or utility. Failure to properly purge the lines or
improper line sizing, will result in ignition failure. This problem is especially noticeable in NEW LP

installations and also in empty tank situations. This can also occur when a utility company shuts off
service to an area to provide maintenance to their lines. The gas valve must not be replaced with a
conventional gas valve under any circumstances. As an additional safety feature in the Phoenix water
heater, the gas valve in this appliance has a flanged connection to the swirl plate and blower.

E. EXHAUST VENT AND INTAKE AIR VENT SIZING

1. The exhaust and intake vent size is 2" for the PH100 and PH130 and 3" for the PH199.

2. The total combined equivalent length of exhaust vent and intake air pipe should not exceed 85
feet.

a. The equivalent length of elbows, tees, and other fittings are listed in the Friction Loss Table 5-5.

b. For example: If the exhaust vent has two 90° elbows and 10 feet of PVC pipe we will calculate:

Exhaust Vent Pipe Equivalent Length = (2x5)+10=20 feet

Further, if the intake air vent pipe has two 90° elbows, one 45° elbow and 10 feet of PVC pipe,
the following calculation applies:

Intake Air Vent Pipe Equivalent Length = (2x5)+3+10=23 feet

Finally, if a concentric vent kit is used we find:

Total Combined Equivalent Length = 20+23+3=46 feet

Therefore, the total combined equivalent length is 46 feet which is well below the maximum
of 85 feet.

c. The intake air vent pipe and the exhaust vent are intended to penetrate the same wall or roof

of the building.

d. Effort should be made to keep a minimum difference in equivalent length between the intake

air vent pipe and the exhaust vent.

3. The minimum combined equivalent length is 16 equivalent feet.

F. LONGER VENT RUNS

1. The maximum combined equivalent length can be extended by increasing the diameter of both
exhaust vent and intake air vent pipe equally. However, the transitions should begin a minimum
of 15 equivalent feet from the water heater.

a. The maximum equivalent length for the increased diameter vent pipes is 125 feet.

b. Transitions should always be made in vertical sections of pipe to prevent the condensate from

pooling in the vent pipe.

c. If the transition occurs at a distance greater than 15 equivalent feet from the water heater, the

maximum equivalent length will be reduced. See Table 5-7.

G. EXHAUST VENT AND INTAKE AIR PIPE INSTALLATION

1. Use only solid PVC or CPVC pipe. FOAM CORE PIPING IS NOT APPROVED. Refer to chart Section
5-C.

2. Remove all burrs and debris from joints and fittings.

3. All joints must be properly cleaned, primed, and cemented. Use only cement and primer approved
for use with the pipe material. Cement must conform to ASTM D2564 for PVC and ASTM F493
for CPVC pipe.

4. Horizontal lengths of exhaust vent must slope back towards the water heater not less than ¼" per
foot to allow condensate to drain from the vent pipe. If the exhaust pipe must be piped around
an obstacle that results in the creation of a low point, condensate will collect in this low point and
form a blockage. This condensate must be drained away using a field-installed condensate drain
assembly as shown. (See Fig. 1 Section 5)

5. All piping must be fully supported. Use pipe hangers at a minimum of 4 foot intervals to prevent
sagging of the pipe where condensate may form.

6. Do not use the water heater to support any piping.

7. A screened straight coupling is provided with the water heater for use as an outside exhaust
termination.

H. WATER HEATER REMOVAL FROM A COMMON VENT SYSTEM

At the time of removal of an existing water heater, the following steps shall be followed with each
appliance remaining connected to the common venting system placed in operation, while the other
appliances remaining connected to common venting system are not operating.

1. Seal any unused openings in the common venting system.

2. Visually inspect the venting system for proper size and horizontal pitch to determine if there is block­age, leakage, corrosion or other deficiencies that could cause an unsafe condition.

3. If practical, close all building doors, windows and all doors between the space in which the
appliance remains connected to the common venting system located and other spaces in the
building. Turn on clothes dryers and any appliances not connected to the common venting system.
Turn on any exhaust fans, such as range hoods and bathroom exhausts, at maximum speed. Do
not operate a summer exhaust fan. Close all fireplace dampers.

4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust the
thermostat so the appliance will operate continuously.

5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the
flame of a match or candle or smoke from a cigarette.

6. After it has been determined that each appliance remaining connected to common venting system
properly vents when tested as outlined, return doors, windows, exhaust fans, fireplace dampers and
any other gas burning appliance to their previous condition of use.

7. Any improper operation of the common venting system should be corrected so the installation
conforms with the National Fuel Gas Code, ANSI Z223.1. When resizing any portion of the
common venting system, the common venting system should be resized to approach the
minimum size as determined using the appropriate tables in Appendix G in the National Fuel Gas
Code, ANSI Z 223.1

I. CONDENSATE REMOVAL SYSTEM

This is a condensing high efficiency appliance, therefore this unit has a condensate removal system.
Condensate is 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 boiler and
down to a suitable inside drain, if the condensate outlet on the water heater is lower than the drain,
you must use a condensate removal pump (kit P/N 554200 available from Heat Transfer Products,
Inc.) A condensate filter, if required by local authorities can be made up of lime crystals, marble or
phosphate chips that 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.

TEE IN THE LINE AFTER THE CONDENSATE NEUTRALIZER TO PROPERLY REDUCE VACUUM LOCK IN THE DRAIN LINE.

2. PLASTIC PIPE SHOULD BE THE ONLY MATERIAL USED FOR THE CONDENSATE LINE. STEEL, BRASS, COPPER OR OTHERS WILL BE
SUBJECT TO CORROSION OR DETERIORATION.

3. IT IS ALSO VERY IMPORTANT THAT THE CONDENSATE LINE IS NOT EXPOSED TO FREEZING TEMPERATURES, OR ANY OTHER TYPE

NOTES:

CAUTION

The condensate line must remain unobstructed, allowing free flow of condensate. If
condensate is allowed to freeze in the line or if the line is obstructed in any other manor,
condensate can exit from the water heater tee, resulting in potential water damage to
property.

NOTICE

Use materials approved by the authority having jurisdiction. In the absence of other
authority, PVC and CPVC pipe must comply with approved venting material chart in
Section 5-C.
When installing a condensate pump, select one approved for use with condensing
boilers and furnaces. The pump should have an overflow switch to prevent property
damage from condensate spillage.
Condensate from the Phoenix will be slightly acidic (typically with a pH from 3.2 to 4.5).
Install a neutralizing filter if required by local codes.

PART 6. START-UP PROCEDURE

FOR YOUR OWN SAFETY READ BEFORE OPERATING

1. This appliance does not have pilot. It is equipped with an ignition device which automatically lights
the burner. Do not try to light the burner by hand.

2. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor
because some gas is heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor's phone. Follow the gas suppliers'

instructions.

• If you cannot reach your gas supplier, call the fire department.

3. Turn on gas shutoff valve (located inside of the down near burner) so that the handle is aligned
with the gas pipe. If the handle will not turn by hand, don't try to repair it, call a qualified service
technician. Force or attempted repair may result in a fire or explosion.

4. Do not use this appliance if any part has been under water. Immediately call a qualified service
technician to inspect the appliance and to replace any part of the control system and any gas
control which has been under water.

5. The Phoenix shall be installed so the gas ignition system components are protected from water
(dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement,
condensate trap, control replacement, etc.)

A. OPERATING INSTRUCTIONS

If you smell gas, STOP. Follow listed safety instructions above. If you do not smell gas, follow the
next steps.

1. Turn on all electric power to appliance. Make sure tank is full with cold water and purge all piping.
To assure adequate purging, open all hot water faucets.

2. Adjust the temperature setpoint of the Phoenix if desired. The factory default setting is 119°. If
changes are ncessary follow “Overall Appliance and Control Operation” in this section.

3. If the appliance fails to start, refer to the Troubleshooting section in the back of this manual.

B. OVERALL APPLIANCE AND CONTROL OPERATION

To adjust temperature of the stored water press and hold {S3} for 2 seconds. The first item is: DU:
Water Temperature Set Point – factory set at 119°F, adjustable down by pressing S1 key to 70°F and
adjustable up by pressing the {S2} key up to 159°F. The {S3} key is then pressed again momentarily to
display DH, the differential which is factory set at 7°F and adjustable down to 1°F by pressing the {S1}
key and up to 18°F by pressing the {S2} key. Note: Due to the highly advanced control on this appli­ance which compensates for varying inlet water temperature, the actual differential temperature

SHUTDOWN / TROUBLESHOOTING

PART 7: SHUTDOWN

A. SHUTDOWN PROCEDURE

If the burner is operating, lower the set point value to 70 degrees F. and wait for the burner to shut
off. Continue to wait for the combustion blower to stop so all latent combustion gases are purged
from the system. This should take a maximum of 40 to 90 seconds. Disconnect the electrical supply.
If the burner is not operating, disconnect the electrical supply.

B. VACATION PROCEDURE

If there is danger of freezing, change the set point to 70 degrees F. DO NO

T turn off electrical

power. If there is no danger of freezing, follow the "Shutdown Procedure".

C. FAILURE TO OPERATE

Should the burner fail to light, the control will perform two more ignition trials prior to entering a
lockout state. Note that each subsequent ignition trial will not occur immediately. After a failed igni­tion trial, the blower must run for approximately 10 seconds to purge the system. Therefore, a time
period of approximately 40 to 90 seconds will expire between each ignition trial. If the burner lights
during any one of these three ignition trails, normal operation will resume. If the burner lights, but
goes off in about 4 seconds, check the polarity of the wiring. See electrical connection section in Part 4.
If the burner does not light after the third ignition trial, the control will enter a lockout state. This lock­out state indicates that a problem exists with either the appliance, the controls, or the gas supply.
Under such circumstances, a qualified service technician should be contacted immediately to prop­erly service the appliance and correct the problem. If a technician is not available, depressing the
{S4/RESET} button once will remove the lockout state so additional trials for ignition can be per­formed. The unit will try to re-light once every 6 minutes.

PART 8: TROUBLESHOOTING

A. PHOENIX ERROR CODE

An error code may occur in the installation of the Phoenix. This condition may lead to a lock out condition of
the controller, which will need to be manually reset through the {S4/RESET} button. These temporary codes will
help the installer correct the problem before going into a lock out condition, which will require a manual reset.

B. PHOENIX ERROR

1. When an error condition occurs the controller will display an error code on the display module.

2. These error codes and several suggested corrective actions are included in Table 8-2.

3. In the case of |E00|, |E13|, and |E14| this error, if uncorrected, will go into a fault condition as described

in Paragraph C.

C. PHOENIX LOCKOUT

1. When a fault condition occurs the controller will illuminate the red “fault” indication light and display

a fault code in the format (Example: |F00|) on the display module.

2. Note the fault code and refer to Table 8-3 for an explanation of the fault code along with several
suggestions for corrective actions.

3. Press the reset key to clear the fault and resume operation. Be sure to observe the operation of the
unit to prevent a recurrence of the fault.
