Service Tip 1
All 120V wiring on the ELITE control panel is separate from the 24V wiring. The 120V wiring is located on
the terminal strip in front of the transformer. The 24V wiring is located on the terminal strip to the left of the
transformer. Both terminal strips are numbered from right to left; the 120V strip begins with #1 and the 24V
begins with #5. For control panel, see pages 22 through 23.
Service Tip 2
The control panel consists of (2) DPDT relays. The relays are designated as Relay 1, which controls the burn-
er function and is located near the transformer. The second relay, Relay 2, controls the circulator function and
is located on the left side of the control panel.
Service Tip 3
During initial startup the ELITE may emit an odor. This odor is due to the initial burning of ceramic fibers
in the combustion insulation and the oils on the interior tank surfaces. These odors will dissipate as the unit
continues to operate.

Check the Manual Reset Safety Limit.
-The Manual Reset Safety Limit reset button is located on the center of the front control panel.
-If the Manual Reset Limit had tripped then check the following items:
• The function of the Manual Reset Limit.
• The setting of the Manual Reset Limit should be 205ºF.
• The function of the Primary Thermostat.
• Check the Primary return system temperature. The recommended supply/return temperature dif-
ferential is 20ºF to 30ºF.
Check the Burner Control.
Some oil burner controls are equipped with a LED indicator to aid the service technician in diagnosing poten-
tial problems. If a LED is part of the burner control. consult with the control manufacturer and/or the burn-
er manufacturer for a detail list of flash codes and troubleshooting guidelines.
If the burner control contains a reset button, depress the button for approximately 60 seconds and release. If
the burner resets and attempts to ignite, consult the burner manufacturer’stroubleshooting guidelines or the
general troubleshooting guidelines listed on page 17.
Note: If the burner control has no reset button, turn the power supplied to the unit OFF for approximately 60
seconds and then ON.
Check the Incoming Power Supply.
-Access the control panel components per Service Instruction 1.
- Check for voltage across terminals 1 and 2 for 120V.See Service Tip 1.
• If voltage is not present check incoming electrical supply.
- Check for 120V,polarity, across terminals 1 and G. See Service Tip 1.
• If voltage is present across terminals 1 and G, then polarity is correct.
•If voltage is not present check incoming electrical supply wire connections and electrical supply
source.
-Proceed to Check the Transformer and 24V Circuit.
Check the Transformer and 24V Circuit.
-Complete the procedure for checking Incoming Power Supply.

• If voltage is not present, and 120V is supplied to the unit replace the Transformer.
- Proceed to Check the Safety Limits.
Check the Safety Limits.
- Complete the procedures for checking Incoming Power Supply and for checking the Transformer and
24V Circuit.
-Check for voltage across terminals 6 and 7 for 24 volts. See Service Tip 1.
•If voltage is not present, check the following items related to the LWCO device:
- Is the system pressure above 10 psig? The system pressure must be above 10 psig for the LWCO
device to activate.
- If the system pressure is above 10 psig, check for continuity across the LWCO device terminals.
Replace the LWCO device if switch is proven open.
- Check for voltage across terminals 6 and 8 for 24 volts. See Service Tip 1
•If voltage is not present, check the following items related to the Manual Reset Limit:
- Push the reset button located on the Control Panel. Does it reset?
- If the manual reset limit does reset check to ensure limit is set to 205ºF and ensure primary sup-
ply/return differential is 20º to 30ºF.
- Is the Manual Reset Limit functioning properly? Is the manual reset limit tripping at a tempera-
ture setting of 205ºF? Replace the Manual Reset Limit as needed.
- Check the function of the Automatic Reset Limit by:
1. Turn the Secondary thermostat to the highest possible setting. The installer may need to run domes-
tic hot water with the unit shut down in order to cool the inner tank and to initiate a “call for heat” on
the Secondary thermostat.
2. Check for voltage across terminals 6 and 11 for 24 volts. See Service Tip 1. If voltage is not present
check the following:
-Check for voltage across terminals 12 and 6 for 24 volts. If voltage is present continue to run
domestic hot water to cool the unit down.
-Turn the Secondary thermostat to the lowest possible setting and check for voltage across termi-
nals 12 and 6 for 24 volts. If voltage is not present, replace the Secondary thermostat.
3. If 24 volts is present at terminals 11 and 6, check for 24 volt across terminals 14 and 6. If voltage is
not present check the following:
- Is the system temperature below 160ºF?
- If the temperature is below 160ºF, then replace the Automatic Reset Limit.
No Heat Call - Unit is Cold & Burner Not Firing

- If the system temperature is above 160ºF, initiate a “call for heat” within the system and attempt
to cool the unit down. If the unit cools down and the Automatic Reset limit does not reset, replace
the limit.
The reason for either the Manual Reset or the Automatic Reset Limit to activate in a lockout mode may
be due to a low return temperature from the system. It is recommended to maintain a 20ºF to 30ºF dif-
ferential between the primary supply temperature and the primary return temperature. In radiant systems
using a mixing valve or other means of providing tempered water to the system it is recommend to use a
bypass loop between the primary supply and return piping. This by-pass loop should contain a valve that
can be used to divert primary water from the supply to the return. The valve should be adjusted to increase
the return temperature and a supply /return differential of 20º to 30ºF. Once the differential is achieved,
no further adjustments are required on the valve.
Check the Function of “Relay 1”. See Service Tip 2.
• If 24 volts is present at terminals 14 and 6, then check for 120 volts at terminals 4 and 2. See Service
Tip 1.
- If 120 volts is not present at terminals 4 and 2, replace the “Relay 1”.

- Ensure the thermostat wire connection at the Room T-stat Snap-set is connected to C and 1 terminals and
is secured.
- Ensure the system electrical is not feeding 24 volts through the thermostat wires connected to the Room
Snap-set.
• Having a secondary 24 volts incoming through the room snap-set could cause failure of the internal
control components.
Check for the Function of the ELITE System Circulator and Relay 2.
•Access the control panel per Service Instruction 1.
• Turn the Secondary thermostat to the lowest setting.
• Initiate a “call for heat” within the primary heating system.
• Check voltage across terminals 12 and 6 for 24 volts. See Service Tip 1.
-If voltage is not present, check for 24 voltages across terminals 5 and 6, terminals 7 and 6, and ter-
minals 8 and 6 to ensure no Safety Limits are locked out.
• With voltage at terminals 12 and 6, check for 24 volts at terminals 13 and 6. If no voltage is present
at terminals 13 and 6 check the thermostat wires at the Room T-stat Snap-set and check to ensure the
primary system is communicating a “call for heat” to the ELITE.
• With voltage at terminals 13 and 6, check for 120 volts at terminals 3 and 2.
- If no voltage is present at terminals 3 and 2, replace Relay 2. See Service Tip 2.

Is the ELITE properly sized for the domestic water application?
•There are many methods of sizing various domestic hot water applications, i.e ASHRAE sizing tables,
or ASPE domestic water heating design manual. Re-confirm the domestic hot water demand required
for the application.
•Re-confirm the flow rates of the fixtures. Was the domestic demand based on showers heads at 2.0
gpm when they are actually 5.0 gpm? Use a bucket and a stopwatch to determine fixture flow rates.
-Evaluate the hot water usage patterns for a day. Is the peak demand unusually high for the appli-
cation?
- Has the demand for domestic hot water changed since the system was installed? A bathroom
remodeling project with a newly installed whirlpool tub will drastically change the domestic water
demand.
The ELITE will provide domestic hot water at the following rates for a 10 minute dump period with a mix-
ing valve setting for 120ºF:
F-25 5.6 gpm
F-30 6.1 gpm
F-35 6.5 gpm
F-40 7.4 gpm
F-45 8.1 gpm
The outlet temperatureafter 10 minutes will be considerably lower that the initial draw of hot water.
The overall temperatureof the water collected during the draw will be approximately 110ºF.
Is the thermostatic mixing valve properly set?
•The operating range of the mixing valve is 90ºF to 120ºF.
•The mixing valve is equipped with a cap that may be locked into position. Adjust the mixing valve set-
ting to the desired temperature prior to locking the cap.
•The manual valve located on the U-tube should be in the open position.
Closing the manual valve on the U-tube will affect the amount of cold water supplied to the mixing
valve and the overall function of the mixing valve. A potential scalding hazard may exist resulting in
severe personal injury or death.

Does the mixing valve require cleaning due to scaling deposits?
1. Isolate the domestic water supply to the ELITE and relieve any existing pressure.
2. Remove the main valve body from the ELITE using the union connections.
3. Remove the blue cap and locking ring from the valve using a 2.5 mm L key wrench (supplied with the
mixing valve).
4. The interior of the valve body can be removed by unscrewing the large hexagonal nut and sliding the
interior components out. Ensure the orientation of the components is noted so that they can be
reassembled in the correct manner.
5. A mild cleaner that is safe to use on plastic parts can be applied to any scale buildup and then brushed
away with a small bristle brush like a toothbrush.
6. After cleaning and reassembling, the valve should be reset and tested for outlet mixed temperatures
based on mixing valve settings. A record of the temperatures and valve settings should be retained for
future checks.
Does the domestic water system contain a recirculation line?
-The recirculation line circulator must be controlled by an aquastat placed on the recirculation line.
- Not having an aquastat controlled recirculation will cause the mixing valve not to function properly and
will affect the domestic performance of the unit.
It is recommended to set the operating limit of the recirculation aquastat a minimum of 10ºF below
the setting of the mixing valve.
-Ensure the recirculation system contains a check valve to prevent back flow of cold water.

Is the expansion tank on the primary system properly sized?
• Each ELITE unit contains approximately 20 gallons of primary water that needs to be accounted for
in the sizing of an expansion tank.
• Insufficient allowance for expansion on the boiler side can cause the pressure relief valve to lift or
weep.
Is the expansion tank defective, water logged or improperly charged?
• Check for failed gaskets or bladders or a faulty Schrader valve.
• Use a tire gauge to check the charge pressure of the tank with the system pressure at 0 psig. The
diaphragm expansion tank should be pre-charged to 12 psig.
• Check the location of the system circulator in relationship to the expansion tank and pressure relief
valve. The relief valve may be sensing the head pressure of the circulator directly and not the actual
system pressure.
Is the pressure relief valve functioning properly?
•Dirt and water deposits can accumulate under the valve seat.
Check the primary fill valve for defects.
• Is the valve filling the system to the correct pressure of 12 psig to 15 psig?
• Is the valve maintaining the correct system pressure?
Check for possible inner tank leak.
• If possible, isolate the outer tank of the ELITE by shutting the primary supply and return isolation
valves off. Relieve the outer tank (primary) pressure. Observe the primary system pressure during
that time.

Is there a thermal expansion tank installed on the domestic supply piping and is it properly sized?
• A thermal expansion tank is required if the domestic supply piping includes a backflow preventer or
pressure reducing valve.
•Ensure the potable water thermal expansion tank is properly sized for a minimum 20 gallons volume
and pre-charged at the incoming supply pressure.
• During long periods, when there is no draws of domestic hot water (i.e. overnight), the T&P relief
valve may lift or weep due to thermal expansion, but may function properly during normal periods of
domestic draws.
Is the thermal expansion tank defective, water logged or improperly charged?
• Check for failed gaskets or bladders or a faulty Schrader valve.
•Use a tire gauge to check the charge pressure of the tank. The charge pressure of the tank should be
equivalent to the incoming supply pressure or the pressure measured downstream of a pressure reduc-
ing valve.
Check the incoming domestic supply pressure entering the ELITE.
• If the pressure is over 70 psig it is recommended to install a pressure-reducing valve. This will pre-
vent any pressure spikes or increases in pressure due to thermal expansion, which may cause the T&P
valve to lift or weep.
Check the domestic water system for possible sources of water hammering or pressure spikes.
•Some appliances such as clothes washers and dishwashers utilize fast acting valves, which may cause
water hammering or pressure spikes through the domestic water system.
•Install water hammer arrestors as required per the manufacturer’sinstructions or install flexible con-
nectors to isolate the tank from vibrations within the domestic water system.
Is the pressure relief valve functioning properly?
• Dirt and water deposits can accumulate under the valve seat.
If the relief valve continues to weeps. The valve may require replacement.
- Replace the T&P relief will the following relief valve or equivalent:

Is the source of the water from the ELITE?
•Check for possible water seepage through foundation cracks. Did the water appear after a heavy rain?
• Check overhead pipes for leaking connections or excessive condensation.
Is the source of the water from the T&P Relief Valve?
• Place a bucket under the discharge piping of the T&P relief valve and monitor it for the next several
days. This is a procedure that can be completed by the homeowner.
• If the T&P relief valve is the source of water found, refer to the T&P Relief Valve section of this man-
ual (page 13).
The discharge piping of the T&P relief valve is required to be directed towards a suitable place of
drainage. Refer to the Installation manual for additional information regarding the discharge piping
of the T&P relief valve.
Check all piping connections - primary connections and domestic connections
•Check all primary connections at or near the ELITE. A buildup of corrosion is a sure sign of a leak.
• Check the domestic connections. Check around the areas where the domestic connections enter the
outer tank of the ELITE. Excessive water hammering in the domestic system may crack the welds
around the domestic connections and the outer tank shell.
Is the source of the water from the pressure relief valve?
•Place a bucket under the discharge piping of the pressure relief valve and monitor it for the next sev-
eral days. This is a procedure that can be completed by the homeowner.
•If the pressure relief valve is the source of water found, refer to the pressure relief valve section of this
manual (page 12).

The water smells like “rotten eggs”.
The most common cause of water to smell like “rotten eggs” is a non-toxic sulfate reducing bacteria. The
bacteria usually enters into the water system through a break in the supply piping or during construc-
tion/maintenance of the supply piping. The bacteria survives in the water system by converting sulfate
(SO4) in the water to hydrogen sulfide (H2S) gas. It is this gas that creates the “rotten egg” smell. The
presence of hydrogen sulfide can also affect the taste of the water. Along with the stench caused by these
bacteria, black deposits, which typically indicate pipe or fitting corrosion may also appear in the water.
In extremely high concentrations, hydrogen sulfide gas can be toxic. However, the gas is detectable
prior to any harmful levels can be reached.
The bacteria will thrive in any water system under the following conditions:
• High levels of sulfur in the water.
• Activated hydrogen in the water from cathodic reactions within the tank.
• Water with little or no dissolved oxygen.
• Storing the domestic water below 140ºF.
Other causes of smelly or bad tasting water:
•Chlorides of magnesium and calcium gives water a bitter taste.
• Chloride of sodium will produce a salty tasting water.
• Sulfates above 50 ppm in the water gives the water a medicinal taste.
• Carbon dioxide in the water with a low pH results in water that is fizzy.
• Iron and tannic waters will produce water with a bad taste and odor.
The treatment of this situation requires the inner tank and water system to be shock chlorinated. Depending
on the severity of the bacteria within the water system, several treatments may be required.
- To shock chlorinate the ELITE inner tank and water system, introduce (1) gallon of household bleach
into the system.
- Flush the entire system by drawing hot water from every faucet or fixture until the smell of bleach has
diminished.
-Repeat the procedure as needed.
Hot Water from the faucet appears milky.
When water is initially drawn from the faucet it appears to be milky or cloudy, but it becomes clear after
the water is allowed to stand for several minutes. This is usually an indication that the water contains
high levels of soluble gases such as oxygen, chlorine, carbon dioxide, hydrogen sulfide or others.
WARNING
Water Quality Problems

As the water system pressure increases, the amount of gas that the water can hold in a solution decreas-
es. When air and gases are forced out of the heated water, the problem may be evident in one or both of
the following conditions
• Gases, in the form of small bubbles, may make the water appear milky from the tap, but clear after
several minutes when those bubbles will separate. Similar to the reaction that occurs as air bub-
bles form on the walls of a pan shortly before the water begins to boil.
• The release of dissolved gas can also create air pockets and air locks in the water system piping.
This can cause spurts of air or gases when operating the hot water faucet.
There is generally no cure for milky water caused by dissolved gases, although it can be reduced with aer-
ated faucets. In some applications the amount of air and gases precipitating out of the water will reduce
in time. It should be noted that these gases are not harmful to the end user.
Discolored Water from the Hot Water Faucet
The water from the hot water faucet appears discolored: rusty, brown, black or yellow. Because the inner tank
and sensing well is made of stainless steel, which by nature is resistant to corrosion, the problem is not tank
related. The problem is usually a non-toxic iron reducing bacteria that are commonly found in soil, well water,
and water treatment plants and piping systems. The bacteria usually thrives in those systems in which the sol-
uble iron content exceeds 0.2 ppm. The bacteria will feed on the soluble iron in the water producing “rusty”
color water as a by-product of the feeding process.
Variables in which the bacteria can thrive in:
• Elevated levels of iron and manganese in the water.
• Water with little or no dissolved oxygen.
• Water storage temperatures below 140ºF.
Items that can potentially increase the presence of the bacteria:
• Water softeners.
• Well water.
• Long periods of no water movement.
The treatment of this situation requires the inner tank and water system to be shock chlorinated. Depending
on the severity of the bacteria within the water system, several treatments may be required.
- To shock chlorinate the ELITE inner tank and water system introduce (1) gallon of household bleach
into the system.
-Flush the entire system by drawing hot water from every faucet or fixture until the smell of bleach has
diminished.
-Repeat the procedure as needed.

The start up of the ELITE should be performed by a qualified installer, service agency or the gas
or oil supplier. The start up procedure should include a complete combustion test. A complete com-
bustion test must also be performed after any adjustments to the burner factory setting. Failure to
comply with these requirements can result in severe personal injury, death or substantial property
damage.
Combustion Test Guidelines
- The combustion test should be conducted using an electronic combustion analyzer or at minimum a
“Fyrite” type CO2 analyzer.
- The combustion test sample can be taken a point between the flue hood and the barometric damper on
the venting system of the ELITE.
-Ensure the vent system and air inlet duct system are install completely prior to start up and conducting a
combustion test.
