RESOLUTE RT BOILER
IMPORTANT MESSAGE TO HOMEOWNER/USER:These instructions should be carefully read and kept for future
reference to gain the best performance from your Resolute RT boiler.
CONGRATULATIONS ON YOUR PURCHASE OF THE RESOLUTE RT BOILER with its highly efficient low mass
hydronic heat exchanger, the Energy Converter. It is the product of years of engineering and advanced design, which
brings together in a single system all elements needed to provide efficient home heat and hot water. This operation and
maintenance information has been prepared so that you may better understand and use your Energy Kinetics Resolute
RT Boiler and Heating System.
RESOLUTE RT BOILER - PRINCIPLE OF OPERATION
Resolute RT comprises a heat source, the energy converter, circulating water, and five (or more) zones controlled by
an electronic control, the Energy Manager.
The boiler sits cold until a thermostat calls for heat. The Energy Manager receives the call for heat and turns on the
main circulator and burner. Water circulates within the boiler as it warms up to operating temperature. When ready, the
zone valves open and deliver heat to the zones calling for heat. When the thermostats are satisfied, the Energy Manager
turns off the burner and enters the energy recovery stage. The circulator and zone valve stay energized to deliver the
heat remaining in the boiler to your home or to the domestic hot water storage tank.
When energy recovery is complete and the boiler has been cooled off, the Energy Manager turns off the system and
waits for another thermostat (or tank aquastat) to call for heat. Resolute RT runs the burner only when you need heat
and delivers that heat only where you need heat.
The Energy Converter is the product of advanced thermal engineering. It is designed with two separate
passageways, nearly 15 feet long, coiled around each other. Water travels along one passageway from your home
toward the center of the unit and heated gases travel from the unit center toward the chimney. This is a “forced circulation
counter-flow” design and it provides very efficient transfer of heat from the burning fuel to the circulating water. The
superior insulation of the boiler minimizes heat losses to the surroundings, resulting in directing heat to your home in an
efficient and quiet manner.
Resolute RT has an extremely high annual efficiency (over 95% of steady state) because it runs only when your
home or hot water storage tank needs heat. Energy recovery is completed at the end of each heat call, virtually
eliminating off cycle losses.
Your Resolute RT holds a minimal quantity of water so it begins to supply heat in about 2 minutes. This rapid
response means that your rooms can be heated quickly when cold. The Resolute RT can also provide heating of
domestic water just as quickly.
A modern retention head gas burner fires into the center of Resolute RT where a high temperature, light weight
stainless steel chamber provides ideal conditions for “near perfect” efficient, pollution-free combustion. Your Resolute RT
is tightly sealed so all products of combustion pass only to the Smart Vent system.
The Resolute RT boiler is designed with a hinged front cover that allows access to the inside of the boiler for
inspection and cleaning. All access for service is from the front, so the Resolute RT boiler can be placed against a wall or
into a closet.
ENERGY MANAGER - PRINCIPLE OF OPERATION
The left side of the Manager is the input side, which provides 24-volt power supply and connections for thermostats.
The right side is the output side, which starts the burner, circulator, zone valves or zone circulators and the domestic hot
water circulator. See photo of the Manager on the cover.
Lights on the Energy Manager indicate what is calling for heat (left side) and (right side) lights indicate active zone(s),
burner operation and circulator operation. These function lights are an aid in servicing. The following is a typical cycle.
1. SYSTEM WAITING FOR A CALL: The boiler is turned off and sits cold, waiting until a call for heat. The red power
light on the Manager is glowing.
2. CALL FOR HEAT: A room thermostat call starts the cycle. The thermostat light on the left side will turn on for that
zone.
3. PRE-HEAT: Output lights for the main circulator and burner turn on, the circulator starts, and the burner begins firing.
The boiler water circulates through the energy converter via the bypass line, heating up the water.
4. HEAT: Once the boiler water has heated to 140°F (about 90 seconds), the Manager will turn on the zone output light
on the right side. The zone valve will open and hot water will flow to the zone needing heat. The burner runs as long
as there is a thermostat calling and as long as heat is being delivered to the zone. The burner may shut off if the
return temperature exceeds 170°F/190°F (RED burner light turns off) or if the high limit temperature is exceeded
(RED burner light stays on, but the high limit aquastat shuts the burner off).
5. ANOTHER CALL FOR HEAT: If another zone calls for heat while the burner is already running and the return
temperature is above 140°F, the zone output will turn on, immediately supplying heat to the zone.

Resolute RT Gas – November 2020 8
TIP:
6. MONITOR RETURN TEMPERATURE: The Energy Manager continually senses the return temperature and will turn
off the zone outputs if the return temperature drops below 120oF (130o F if Option Switch #1 is ON). With the zone
outputs closed, the boiler water will quickly reheat and once the return temperature reaches 140oF (150o F if Option
Switch #1 is ON), then the Energy Manager will reopen the zone valves.
7. THERMOSTAT SATISFIED: The thermostat light on the left side will go out. The burner light and the burner will then
turn off.
8. ENERGY RECOVERY: The circulator and zone valve remain energized. The circulating water will remove the energy
from the converter, sending the heat to the last zone that called. The energy recovery stage continues until the return
temperature has dropped sufficiently or until maximum timing has been reached. The boiler is now sitting cold,
waiting for the next call for heat. Maximum timing for heat recovery stage is usually set at twenty minutes for space
heating zones and is fixed at five minutes for the Hot Water zone. (See Energy Manager Option Switch Settings).
RECEIVING and UNPACKING
Inspect shipment upon receipt for external damage. When
unpacking and uncrating, inspect each item for internal
damage. Any damage found should immediately be
reported to the freight carrier before installation. The
receiver is responsible for following the claims procedure of
the freight carrier. The freight carrier is responsible for taking prompt action
on all claims. If freight cannot be inspected at the time of delivery, sign the
bill of lading “Subject to Inspection” and inspect the shipment as soon as
possible after receipt. Replacements for parts damaged in shipment are
available upon receipt of a signed copy of a claim report (concealed damage
claims should be filed immediately against the freight carrier by the
consignee).
After unpacking, check each item against the packing list. Inspect it
thoroughly for loose parts, instruction sheets and packing lists. Immediately
report any missing items. It is wise to complete the installation before
discarding packing material. Store all parts where they will not be damaged
or lost during installation.
LOCATION and CLEARANCE
DANGER:Provide clearance to combustible surfaces in accordance with
all local and national codes. Follow National Fire Protection
Association Bulletin NFPA Installation of Oil Burning Equipment and all applicable codes.

Resolute RT boilers come with a stand mounted at the factory which provides a convenient, solid, level and smooth
foundation for the boiler. Place the unit as near to the venting location as possible allowing clearance for front cleaning
and service as shown in Figure 1B
NOTICE: The stand must be level to slightly higher at the back, to allow for proper venting of air from the boiler.
SMART VENT SYSTEM
The Smart Vent with Dilution Air System is a complete vent system that has been specifically designed for use with
Energy Kinetics’ Resolute RT boiler. It uses a Dilution Air Exhaust Fan (inducer) and requires outside air for combustion
air. Each part of this system works together and must be installed properly to work correctly.
Starting with combustion air, outside air must be piped directly to the factory supplied PVC air inlet tee. The PVC
branch on the inlet tee is connected to the sealed air box and provides combustion air using PVC pipe and elbows
supplied.
The Dilution Air Exhaust Fan (inducer) assembly is factory mounted directly on the boiler breech. The boiler pressure
vessel is maintained at negative pressure by the forced draft fan. A fan proving safety switch is wired in series with the
puff switch and blocked inlet switch to the ‘BV’ terminals on the primary control. A safety recycle or lockout occurs on the
primary control if ‘BV’ is interrupted if operation of the forced draft fan is not proven. The system requires no draft
adjustment when installed as recommended and is designed for use without any draft damper.
Combustion air is piped from the branch of the dilution air tee to the PVC male adapter on the sealed air box frame.
Piping of outside air directly to the boiler is required to ensure that adequate fresh air is available for combustion and
proper dilution of flue gasses. It completely isolates the boiler from the home environment, as well as greatly reducing
operating noise from the boiler. A blocked air intake safety switch is wired in series with the standard Resolute RT
blocked vent switch and fan prover. Burner operation will be prevented if the air inlet is blocked or if the boiler flue
passage is blocked.
The Smart Vent system for the Resolute RT boiler must be installed according to the Smart Vent with Dilution Air
installation manual.

WARNING: Ensure that all gear clamps on the Dilution Air adapter are tightened. After installation pull upwards on the
vent to confirm a good mechanical connection. Failure to properly tighten all gear clamps can result in a failure of the
venting system.
WARNING: Sidewall venting and combustion air piping from outside the building is required. The Energy
Kinetics Smart Vent kit contains specific instructions for installation that must be followed. For length of run for intake air
and for the vent connection, refer to the Smart Vent with Dilution Air installation manual. Combustion air may be supplied
through PVC pipe. A Tek-screw joint allows the door to swing down when the air inlet pipe is disconnected.
GAS BURNER MOUNTING
Resolute RT boilers are shipped from the factory with the gas burner mounted. The burner flanges are designed to
insert the burner head 2-3/8” into the boiler. Energy Kinetics installs a ceramic sleeve, the amulet, to protect the burner
head from the heat of combustion, and then seals the air tube flange joint with a high-grade retort cement.
NOTICE: Gas burners for field installation or for field replacement should be installed according to burner manufacturer
instructions, according to installation instructions below, and with consultation from Energy Kinetics for any special
considerations or adjustments.
Follow these instructions for field installation or replacement of Energy Kinetics supplied burners. Start by checking
electrode and flame sense rod position per manufacturer’s specifications prior to assembly to unit. Test fit the amulet by
inserting the amulet into the boiler opening. If the amulet doesn't easily slide into the boiler, then gently sand the outside
diameter of the amulet until it will fit into the boiler opening. Test fit the amulet onto the burner head. The amulet for the
Carlin burners has a smooth interior. If the amulet is a tight fit on the burner head, then slightly moisten inside the amulet
with water.
Place a 3/8" bead of retort cement onto the burner head at the flange to air tube joint, and slide the (moistened)
amulet over the burner head and against the flange. Ensure proper seating of the amulet by pressing the amulet onto the
burner with a flat object. Leave the excess retort cement at the amulet to flange joint and the cement will provide an
airtight seal of the air tube flange to the boiler face.
The Carlin amulet does not have an edge and when fully seated the amulet will be flush with the front of the Carlin
burner head. If needed, trim the front edge of the amulet to be flush with the front of the burner head.
Once the amulet has been seated and trimmed, then install the burner into the boiler by carefully inserting the air tube
with amulet into the boiler opening while aligning the burner flange holes with the boiler studs. Install flat washers and
nuts onto the boiler studs and tighten all nuts evenly.
GAS BURNER SETTINGS
Resolute RT gas boilers are shipped from the factory preset for 100,000 Btu/Hr firing rate.The following table lists

GAS PIPING SYSTEMS
The boiler and its individual shutoff valve must be disconnected from the gas supply piping system during any
pressure testing of the gas supply piping system at test pressures in excess of 1/2 psi (3.5 kPa, 14 in wc).
The boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during
any pressure testing of the gas piping system at test pressures equal to or less than 1/2 psi (3.5 kPa, 14 in wc).
A manual shut off valve and a sediment trap must be provided in the gas piping upstream of the electric combination
gas valve at the boiler. The boiler and its gas connection must be tested for gas leakage before placing the boiler in
operation.
Gas piping must be properly sized in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or
according to state and local codes as applicable. Gas piping must be sized to provide the maximum firing rate gas flow

Resolute RT Gas – November 2020 11
for all appliances in the building. For Natural Gas installations, be sure to verify that the gas meter is properly sized for all
appliances. Do not use any service 90oelbows. Use only full port shutoff valves. If in doubt, oversize the piping.
BEST PRACTICE: Always size piping based on natural gas pipe size guidelines.
The following tables provide suggested sizing for Black Iron Pipe. Be sure to add the appropriate equivalent length for
every fitting and elbow used. For other types of pipe or tubing, consult NFPA 54 or the manufacturer of the pipe or tubing
or your gas supplier for pipe sizing information.

ZONE CONTROL BY VALVE: The Resolute RT boiler is designed to provide multi-zone control of the heating system
and optionally can supply domestic hot water. Energy Kinetics recommends and supplies two wire, full port, 24-volt zone
valves for control of each heating zone. A system with a single heating zone still requires a zone valve to provide control
for preheat of unit and to maintain minimum temperature during operation.
ZONE CONTROL BY CIRCULATOR:
Zone control by circulators requires a
flow valve, circulator and 24-volt relay
(EK# 10-0412-RIB or equivalent) for
each zone. The main circulator and
boiler bypass line are still used in these
cases.
NOTICE: An additional tee must be
installed into the supply on the inlet
side of the main circulator. This tee is
the supply for circulators with returns
for these zones into normal return
location. Call Energy Kinetics and
request “Zoning with Circulators”
diagram.
ZONE PURGING: Valves to isolate
and purge individual zones should be
installed according to good piping
practices.
EXPANSION TANK SIZING: The type and size of expansion tank depends on the total system water volume. The
Resolute RT contains 3 gallons of water. NOTICE: Sizing must consider cold start and hot operation due to system
concepts of energy recovery and rapid heat up.
BOILER BYPASS LINE AND VALVE
NOTICE: Systems are piped at the factory with the boiler bypass line and bypass ball valve. The bypass
valve must be at least partially open for the boiler to operate properly.
FILLING WITH WATER, VENTING, and PURGING
When piping is completed and all accessories installed the Converter and piping should be filled with water. The
Converter purges itself of air when properly installed. NOTICE: AIR VENT CAP MUST REMAIN OPEN.Vent cap
should be removed and kept in a safe location. Each zone should be purged until a steady stream of water without air
passes out of purge hose. Vent all radiation.
NOTICE: DO NOT START BURNER UNTIL CONVERTER AND SYSTEM ARE FULL OF WATER.Fill to normal
cold system pressure, 10 to 12 psi on pressure gauge. Before placing system in operation, carefully check for leaks
throughout system. Tighten pipe joints, circulator flanges; check gaskets, etc., as needed.
BOILER WATER TREATMENT
Addition of boiler water treatment is recommended to reduce lime buildup inside the boiler. Energy Kinetics
recommends addition of one quart of 8-Way Boiler Treatment per 30 gallons system water. 8-Way Boiler Treatment is
recommended to treat water up to medium hardness. Call Energy Kinetics for more details about boiler water treatment
and about hard water conditions.
ANTI-FREEZE
Only non-toxic antifreeze (such as Propylene Glycol) should be used if adding anti-freeze to a system that produces
domestic hot water. Hard water should not be used in combination with generic antifreeze. Energy Kinetics supplies a
quality inhibited Propylene Glycol anti-freeze with orange dye and an antifoam agent. 8-Way Boiler Treatment can be
added to Energy Kinetics anti-freeze and is recommended in areas of medium water hardness. NOTICE: Thoroughly
clean system prior to adding antifreeze. TSP is recommended for removing flux and other oil based compounds.
Once system has been cleaned and flushed, then add antifreeze to obtain approximately a 30% by volume mixture of
antifreeze in water. Call Energy Kinetics for assistance in calculating how much anti-freeze to add to system.

WINTERIZING
NOTICE: If the Resolute RT boiler may be exposed to freezing temperatures, such as a vacation home shut down for
the winter, then anti-freeze should be added. When a home is winterized by draining all domestic water piping, then the
Resolute RT boiler must be protected. It is not recommended to drain the boiler, because introducing air into the boiler
can cause rusting inside the boiler shell and also because the Energy Converter has a spiral water passage that cannot
be completely drained of water. When draining the domestic water piping system, be sure to drain the domestic side of
the plate heat exchanger. If the hydronic system will not be drained, then add enough anti-freeze to protect the entire
hydronic system including the boiler, piping, radiation, circulators, etc. If the hydronic system will be drained, then add
shut off valves to isolate the boiler and add anti-freeze to the boiler only, as follows. Drain water from the boiler and then
add anti-freeze to the boiler. Refill boiler with water and run boiler circulator through the bypass to distribute antifreeze
within boiler. Propylene Glycol in water will provide the following freeze protection: 30% down to +8°F, 40% to -8°F, 50%
to -27°F. Energy Kinetics recommends using 30% anti-freeze to obtain the best boiler performance. Use over 30% anti-
freeze only if lower temperature freeze protection is mandatory.
Caution: Always keep the fuel supply valve shutoff if the burner is shut down for an extended period of time.

ELECTRICAL CONNECTION - LINE VOLTAGE
POWER SUPPLY: 120 VOLT 60 HZ, 7.5 Amperes
Resolute RT requires 120 VAC. The supply voltage must be within 108 VAC min / 132 VAC max for reliable operation
of the boiler and the Manager. An easy way to check the supply voltage is to plug a voltmeter in at the service outlet
located on the side of the system junction box.
DANGER: Make All Connections with Power Off at Main Circuit Box
Figure 3A: Connect power from a separate 15 AMP fused circuit. Install 3rd wire grounding for proper bond between all
electrical accessories. The system switch is included so power can be shut off at the unit for servicing.
Pigtails are provided for the line voltage power connection. Connect black pigtail to hot, white pigtail to neutral, and the
green pigtail to ground.
WARNING: The junction box is wired at the factory with the service outlet always powered, even with the System
Emergency Switch turned off. To have the service outlet controlled by the System Emergency Switch, move the service
outlet black lead to top lug of system switch. A low water cut-off may be field installed if required by local codes and is
available from Energy Kinetics.
LOW VOLTAGE WIRING
ENERGY MANAGER OPERATES ONLY ON 24 VOLTS 60 HZ POWER
WARNING: Make All Connections with Power Off at Main Circuit Box
A typical low voltage wiring diagram for the Energy Manager is shown in Figure 4A. Thermostats must be
located on inside walls away from cold drafts, windows or heat from fireplaces, appliances or sunlight. Set thermostat
heat anticipators to 0.1 amps or Hydronic option. Call Energy Kinetics to request alternate low voltage wiring diagrams to
handle special situations such as air handler wiring, heat pump wiring, isolation relays for thermostats, and isolation relays
for heat motor style zone valves or circulators, etc.
The single 24-volt/50VA transformer is suitable for the Energy Manager and five zone outputs (zone valves or
relays). NOTICE: Additional load such as extra valves may require greater transformer capacity. To add transformers,
wire in parallel as follows: wire terminal “A” on one transformer to “A” on the other. Repeat with other low voltage terminal
“B”. Be sure to verify 24VAC output from all transformers.
The Energy Manager is designed to heat domestic water and up to four (4) heating zones. Use Energy Kinetics
supplied zone valves with two wire connections. For more than four heating zones, use Energy Kinetics expanded 10 or
15 zone Energy Manager, or call Energy Kinetics for alternatives.
LOW VOLTAGE WIRING DIAGRAM
INSTALL ENERGY MANAGER
The Energy Manager is shipped in its own protective shipping box. NOTICE: The option switches can be set very
easily before the Manager is installed. Locate the pre-wired quick connectors fastened to the front of the junction box by
two cable ties. Cut the two cable ties and discard. Fasten the Energy Manager to the junction box with the four corner
screws. Slide the two quick connectors onto the Energy Manager. Label each zone on the manager, using the adhesive
labels supplied.

Display Manager Option Menu Descriptions
Fuel Type - VIEW-ONLY. Must be set using physical option switch on bottom of Manager Board
This menu can be used to view the setting of physical option switch one, which determines the Fuel Type setting.
Venting - VIEW-ONLY. Must be set using physical option switch on bottom of Manager Board
This menu can be used to view the setting of physical option switch two, which determines the Venting setting.
SmartBoostTM - Default setting is OFF
This option turns the SmartBoost function ON or OFF. While ON, if a zone has been calling for heat for 25 minutes
(optionally 45 minutes), then SmartBoost kicks in to help satisfy that zone sooner by boosting the maximum return
temperature to be 190°F/175°F from the standard 170°F/155°F. The boosted zone will stay at the 190°F/175°F
setting for up to 25 minutes after the call is satisfied.
SmartBoostTM Delay - Default setting is 25 Minutes
This option sets the delay to either 25 minutes or 45 minutes before SmartBoost raises the maximum return
temperature to be 190°F/175°F. This option only impacts boiler operation if SmartBoost is ON.
HW Zone - Default setting is Hot Water
This option will allow the hot water zone to be turned into a heating zone. While this option is set to Heating, the “Hot
Water Zone” will act as a heating zone with 20 minutes of thermal purge. This change will allow the hot water zone to
become a fifth heating zone, for those cases where domestic hot water isn’t required.
HW Priority - Default setting is NO
This option allows the Hot Water Zone to have priority over heating calls for 20 minutes. While this option is set to
YES, the Energy Manager will ignore heating calls to the system for the first 20 minutes of a hot water call. After 20
minutes, or when the hot water call is satisfied, the system will resume providing heat to the rest of the zones.
MultiPurgeTM - Default setting is OFF
This option turns the Multipurge function ON or OFF. While ON, any zones finishing in the prior 20 minute period will
purge with the last zone satisfied. Setting the Purge Time for a given zone to 5 minutes prevents that zone from multi-
purging.
Zone Purge Times - Default setting for each zone is 20 Minutes
This option sets either a 20 minute or 5 minute purge time for heating zones. After all zone calls have been satisfied,
there may still be heat remaining in the boiler. Instead of wasting that remaining heat, the Energy Manager will keep
the last calling zone (or zones, if Multipurge is ON) open to allow the heat to be purged out of the boiler and into the
system. The user is able to choose to let the boiler purge for either 5 minutes or 20 minutes before closing the zone.
Any zone set to 5 minutes will also have Multipurge disabled for that zone. Regardless of the selected option, the
Energy Manager will always end purging and close the zone when the return temperature has dropped sufficiently.
The following types of zones are recommended to have a 5 minute purge time.
•AIR HANDLER / FAN COIL
•VERY SMALL ZONE (like an individual bathroom)
•RADIANT ZONE with STORAGE TANK
Secondary Zones - Default setting for each zone is OFF
This option allows for primary/secondary operation. If any secondary zone is enabled, the manager will assume that
zone 3 controls the injection zone (IZ) and zone 4 controls the loop circulator (LC). Any zone that gets a call while set
as a secondary zone will also activate the IZ and LC, when needed. Thermostats connect to zone 1 (T1) and zone 2
(T2). If the hot water zone is set as a heating zone, the HWZ will also be displayed under the Secondary Zones
options.
INSTALLATION TIPS
•Option Switches “OFF”
Display Managers are shipped with
both dip switches “OFF” (set for an oil
system with a chimney).
•Burner Restart
Thermostat short cycle protection is
25 seconds
•Manager Reset
Shutting the power off momentarily
and then back on again resets the
manager from the short-cycle delay
or an error condition.

EXPANDED ENERGY MANAGER
15 ZONE MANAGER INSTALLATION INSTRUCTIONS
1. Remove cover from junction box.
Use a free knockout on the top of the junction box to mount a second or third transformer, wire black lead to “XFMR”
and white lead to “NEUTRAL” on relay board in box. (Use sections marked “120 VOLTS” only.) A second junction
box is not needed for the expanded Energy Manager. Wire additional transformer(s) in parallel with first transformer.
To wire in parallel, wire terminal “A” on one transformer to “A” on the other. Repeat with other low voltage terminal
“B”. Verify 24VAC output from all transformers BEFORE reconnecting the Manager.
2. Mount long panel on top of box cover with long screws provided in lower 4 holes with spacers down.
3. Mount expanded Energy Manager to cover plate over 4 long screws and 2 wide bolts (top 2 holes).
4. Wire the bottom half of expanded manager as 5 zones Energy Manager. For top half, attach one thermostat lead to a
zone and the other to A1 on lower half of manager. Attach one lead from zone valve or relay to corresponding zone
output and the other lead to 24VAC on lower half.
5. Option switches set fuel type (oil or gas) and venting (chimney or power vented).
See Location of Switches: Figure. 4B.
6. NOTE: When using secondary zones with 15-zone manager, zone 13 controls injection zone, and zone 14 controls
loop circulator.
NOTICE: When operating without an expanded manager, use a 5 zone service board for the lower half. If you do not
have a service board, refer to “Operation of Boilers without Energy Manager” in the Tech Manual.

PREPARE FOR START UP
DANGER: MAKE CERTAIN THE FOLLOWING REQUIREMENTS HAVE BEEN SATISFIED BEFORE START UP:
1. The boiler and piping are completely filled with water.
2. Re-check wiring to ensure that it is correct and in accordance with appropriate wiring diagrams and codes.
3. Verify that proper gas orifice size is used.
4. Verify electrode and flame sense rod settings.
5. Verify the burner settings for air band position and head position (see "Gas Burner Settings" Table).
6. Gas supply is connected to burner. Gas supply lines and shut-off valves are open.
7. Gas lines are purged.
8. Verify operating gas pressure at inlet of gas valve.
9. Adjust bypass valve on boiler side of heat exchanger to half open (see #4 under “Gas Burner Operation”).
10. Polypropylene flue pipe properly connected from unit to sidewall vent hood or chimney kit. All joints are secured and
sealed with integrated gaskets – all interior connections must utilize lockrings.
11. Combustion air supply is available and sufficient. (See “Combustion Air”)
12. NOTICE: Do not punch a hole in the polypropylene flue pipe.
13. Loosen both of the 1/8” plugs in front door of the boiler, one for use as the overfire sampling location and the other for
the breech sampling location.
START UP PROCEDURE
Turn on system supply switch and burner supply switch. The Display Energy Manager lights should come on briefly,
the circulator relay should close briefly, and then the Display Energy Manager will show a red light next to 'power' and
yellow lights on the left side if any thermostats are calling.
1. If needed, adjust a thermostat to call for heat. Burner and main circulator should come on at the same time. If not,
check primary control and reset it if necessary.
2. Check for burner light off. If gas piping is not well purged, then several starts may be required to clear air from gas
piping.
3. On light off, water temperature and flue gas temperature will start to rise. A slight odor is common on initial light off as
combustion chamber and converter surfaces warm for the first time.
4. NOTICE: Perform carbon monoxide test two minutes after light off. If the carbon monoxide exceeds 400 ppm air-free
after two minutes of operation, shut off boiler immediately and repeat "Prepare for Start Up" checklist. (See “Air-free
method of measuring CO”)
5. Once the boiler heats up and reaches temperature, Display Energy Manager “Heating” light will signal heat
distribution to zone(s) calling for heat.
6. Allow system to run about 15 minutes before testing and recording burner operation. (See "Gas Burner Operation")
