Trinity Ts│Installation and Operation Instructions Ts Series
4.0 GENERAL VENTING
The Trinity Ts is a “Direct Vent” boiler requiring a “Special Venting System” designed for pressurized venting.
Both the Vent and Air-Intake piping must be piped to the outdoors, using the vent material and rules outlined in
this section. Under no conditions may this unit vent gases into a masonry chimney, unless it is vacant, and
utilizes the approved venting material and rules described in this section. Installations must comply with the
National Fuel Gas Code, ANSI Z223.1 (U.S.) or CSA B149.1 (Canada) and local requirements.
Combustion Air-Intake Contamination
Be careful not to locate the Air-Intake termination in an area where contaminants can be drawn in and used for
combustion. Combustion air containing dust, debris or air-borne contaminants will drastically increase the
required maintenance and may cause a corrosive reaction in the Heat Exchanger which could result in premature
failure, fire, serious injury, or death. See Table 4-1 for a list of areas to avoid when terminating air-intake piping:
Table 4-1 Corrosive Products and Contaminant Sources
Products to Avoid Contaminated Sources to Avoid
Antistatic fabric softeners, bleaches, detergents, cleaners Laundry facilities
Perchloroethylene (PCE), hydrocarbon based cleaners Dry cleaning facilities
Chemical fertilizer, herbicides/pesticides, dust, methane gas Farms or areas with livestock and manure
Paint or varnish removers, cements or glues, sawdust Wood working or furniture refinishing shops
Water chlorination chemicals (chloride, fluoride) Swimming pools, hot tubs
Solvents, cutting oils, fiberglass, cleaning solvents Auto body or metal working shops
Refrigerant charge with CFC or HCFC Refrigerant repair shops
Permanent wave solutions Beauty shops
Fixer, hydrochloric acid (muriatic acid), bromide, iodine Photo labs, chemical / plastics processing plants
Cement powder, crack fill dust, cellulose, fiber based insulation Concrete plant or construction site
Flammable Solvents and Plastic Piping
Due to the extremely flammable characteristics of most glues, cements, solvents and primers used in the process
of joining plastic vent and air-inlet pipe, explosive solvent vapors must be evacuated from the vent and air-intake
prior to start-up. Avoid using excess cement or primer that may lead to pooling inside the pipe assembly. Freshly
assembled piping assembly should be allowed to cure for a minimum of 8 hours before applying power to the gas
fired boiler. Refer to Mandatory Pre-commissioning Procedure for Plastic Venting
to reduce these risks. Failure to follow these instructions can cause explosions, property damage, injury or death.
Near Boiler Vent/Air-Intake Piping
Each Trinity Ts is equipped with a short piece of approved CPVC vent pipe. Insert one end into the boiler flue
outlet adapter and cement
vent pipe should extend fully into the boiler flue outlet adapter (see Table 4-2). DO NOT
directly into the flue outlet connection as it can deform from the clamping force of the gear clamp. Ensure that
the venting system does not apply a load or strain on the boiler flue outlet adapter. The manufacturer
recommends using two elbows to create a “swing joint” to reduce potential strain on vent piping and cemented
joints. See Figures 4-1 through 4-3 for illustrations.
Vent and Air-Intake to be piped separately. The Trinity Ts cannot share a common vent or
air-intake with multiple boilers.
Failure to comply will result in serious injury or death.
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this
or any other boiler. Failure to follow instructions may result in serious injury or death.

Trinity Ts│Installation and Operation Instructions Ts Series
Mandatory Pre-commissioning Procedure for Plastic Venting
1) Working with the power turned off to the boiler, completely install the vent and air intake system, securely
cementing joints together. If possible, allow primers/cements to cure for 8 hours before firing the burner. If
curing time is less than 8 hours, proceed with Steps 2 through 6.
2) Maintain the boiler gas supply shut-off valve in the off position.
3) Disconnect electrical leads to the Hot Surface or Spark Igniter. Ensure the cables are placed in a fashion
where they will not arc to ground or other conductor.
4) Turn power on to the boiler and apply a heat demand.
5) Allow for 3 complete trials for ignition, consisting of pre and post purge of the combustion blower, until an
ignition lockout occurs. Repeat the process two more times (i.e. 9 complete ignition sequences in total).
6) Turn power off and reconnect the electrical leads to the Igniter.
Vent/Air-Intake Pipe Length Determination
Use Table 4-4 to determine the maximum pipe length that can be used. The table calculates sweep, 90º elbows,
and 45º elbows at 5 equivalent feet [1.52 m] each. Length calculations need not include the three 90° elbows of
the exterior vent piping (two outlet, one inlet).
Example: A Ts80 can be installed with 105 equivalent feet [32 m] of air-intake piping and 105 equivalent feet
[32 m] of vent piping. See Table 4-4 for more details.

Venting Rules and Guidelines
1. Prevailing Winds: Ensure the vent is located where it will not be exposed to normal prevailing winds.
2. Combustion Air-Intake Contamination: Air for combustion must be drawn from outdoors from an area
free of dust and contaminants. Combustion air containing chemicals such as chloride, fluoride, bromine or
iodine or dust and debris will cause corrosion damage of the heat exchanger voiding your NTI warranty.
Refer to Table 4-1 for a list of corrosive products and contaminants sources to avoid.
3.Vertical Separation: The exhaust must be a minimum of 18” [457 mm] above the air inlet, and the air inlet
must always be a minimum of 12” [305 mm] plus snow allowance above any surface that will support snow.
(Two feet plus snow allowance is highly recommended). Consult your weather office, for the maximum
typical snowfall for your region.
Example: New Brunswick Canada - typical maximum snowfall is 19”, thus the inlet must be (12”+19”)
31” above grade and exhaust must be (31”+18”)
4.Horizontal Separation: The horizontal distance between the inlet and exhaust must be a minimum of 4”
[102 mm] center to center. When the horizontal distance between the inlet and exhaust is greater than
[305 mm], the difference in horizontal distance
the same amount.
Example: The horizontal distance (HD)
= 24” [610 mm] and the vertical separation (VSmin) = 18” [457
mm], the new vertical separation (VSnew) can be calculated using the following equation:
(If the horizontal distance is greater than 6’ [1.83 m], no additional vertical spacing is required. Vertical
separation is never required to be greater than 36” [915 mm].
5.Wall Flashing: Under normal operating conditions this boiler will produce a plume of white gases, and
should be taken into consideration when selecting an adequate location. A 36” [915 mm] diameter stainless,
plastic, or vinyl shield can be used to flash the exterior of the residence.
6.Flue Gas Hazard: Position the vent termination where vapors cannot make accidental contact with people
and pets or damage nearby shrubs and plants.
7. Elbow Extensions: Elbows on outside of wall must be no more than ½” [13 mm] away from the wall.
8. Vent Sloping: All indoor exhaust piping must be on a slope back to the boiler a minimum of ¼” per linear
foot of vent [6.25 mm per linear 305 mm]. For applications where excessive condensation is possible ½” per
linear foot [13 mm per linear 305 mm] is recommended.
9.Vent Supports: Where re quired Vent and Air-intake piping shall be secured to the wall for more rigidity.
All interior vent pipe shall be supported a minimum of every 36” [915 mm].
10. Roof Exhaust: In all roof applications the discharge must point away from the pitch of the roof.
11. Roof Flashing: Install adequate flashing where the pipe enters the roof, to prevent water leakage.
12. Rain Cap: Install and seal a rain cap over existing chimney openings, in vacant chi mney applications.
13. Venting Below Grade: Fo r installations that exit the wall below grade refer to Figure 4-9.
14. Vent Screens: Install factory supplied vent screens on the outside of the last elbow for both the inlet and
exhaust vent terminal elbows. Install the screen into the female opening of the elbow. Then cut a small piece
of pipe to sandwich the screen into the elbow. NOTE be sure that the small piece of pipe cut, does not
extend past the end of the elbow. Two screens are provided in the package. See Figures 4-6 and 4-7. Vent
screens are included in Optional Termination Kits.
15.Pipe Sizing: It is extremely important that the intake and exhaust vent piping be adapted to the appropriate
size immediately upon exiting the boiler cabinet. Refer to Figure 4-1 and Table 4-4.
16.Condensate Hazard: Do not locate vent over public walkways, driveways or parking lots. Condensate
could drip and freeze resulting in a slip hazard or damage to vehicles and machinery.
17.Warning Plate: Install the warning plate “Gas Vent Directly Below”, directly above (within 4 ft [1.22 m]
vertically) the location of the air inlet pipe, so it is visible from at least 8 ft [2.4 m] away. See Figure 4-16.
18.Wall Thickness: Direct vent terminations are designed to work with any standard wall thickness.
Installation guidelines for min/max wall thickness are as follows: Min.= 1” [25mm], Max.= 60” [1.52 m].
19.Venting Options: Due to potential moisture loading (build-up) along the exterior wall, sidewall venting
may not be the preferred venting option. Refer to Figures 4-2(b) and 4-3(b) for roof top venting options.

connected to it. Instructions have been provided on how to remove the existing boiler and how to resize the
remaining venting system. Failure to follow these instructions may result in property damage, serious injury or
death.
At the time of removal of an existing boiler, the following steps shall be followed with each boiler remaining
connected to the common venting system placed in operation, while the other boilers remaining connected to the
common venting system are not in operation.
Steps to Removing an Existing Boiler
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch. Verify that there is no blockage,
restriction, leakage, corrosion or other deficiencies which could cause an unsafe condition.
3. Insofar as is practical, close fireplace dampers, all building doors and windows and all doors between the
space in which the boilers remaining connected to the common venting system are located and other spaces
of the building. Turn on clothes dryers and any boiler 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.
4. Place in operation the boiler being inspected. Follow the lighting instructions. Adjust thermostat so boiler
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, cigar or pipe.
6. After it has been determined that each boiler remaining connected to the common venting system properly
vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other
gas burning boiler 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/NFPA 54 and/or CAN/CSA B149.1, Natural Gas and
Propane Installation Code. 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 Part 11
of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CSA B149.1, Natural Gas and Propane
Installation Code.
Extra precaution must be taken to adequately support the weight of the Vent/Air-Intake
piping in applications using roof-top terminations. Failure to follow these instructions
Under no circumstances may an existing chimney or chase-way be used to vent or
provide combustion intake air to a Trinity Ts. Failure to follow these instructions will
Do not install the Trinity Ts into a common venting system with any other boilers.
Failure to comply with this warning will cause flue gas spillage and leech carbon
When an existing boiler is removed from a common venting system, the common
venting system is likely to be too large for proper venting of the remaining boilers

6.0 CONDENSATE DRAIN
This unit produces liquid condensate in the heat exchanger and venting system as a product of combustion.
Steps must be taken to ensure that condensate does not collect in the venting system; therefore, all exhaust
piping must slope back to the boiler a minimum 1/4” per linear foot of vent. Condensate must be drained from
the unit into a household drain.
condensate must be neutralized prior to entering a drain).
The following are important notes that must be taken into consideration when constructing the condensate drain
system (See Figure 6-1 for further details):
•DO NOT install condensate lines outside. A frozen or blocked drain will cause the condensate to fill the
combustion chamber. This will result in a no heat condition, as the unit will shut down, and damage to the
flame sensor, and components can occur.
•NEVER use copper, steel, or galvanized piping in the construction of the condensate system (condensate is
very corrosive and will corrode most metals).
• When a condensate pump is used or required, select a pump that is designed for residential furnaces.
the boiler must be inspected for component damage, e.g. the internal insulation at the front and back of the
chamber. Failure to follow these instructions may result in fire, property damage, serious injury or death.
Check with your municipality, or local gas company to determine if the disposal of
combustion condensate is permitted in your area (e.g. in the State of Massachusetts the
If the combustion chamber has been flooded due to the condensate drain backing up, or
for any other reason, the combustion chamber door must be removed and the inside of

7.0 INSTALLING GAS PIPING
Conversion Kit (see Table 7-1) must be installed prior to installing the gas piping to the boiler. Failure to
properly convert the unit to operate with Propane may result in property damage, serious injury or death.
Codes as they may require boilers fueled with LP gas be provided with an approved means of removing
unburned gases from the room. Failure to follow these instructions may result in serious injury or death.

Trinity Ts80 82650-1 34 (3.4mm)
Installation
Refer to the current National Fuel Gas Code ANSI Z223.1/NFPA 54 or CAN/CGA B149.1 installation codes,
and local codes for gas piping requirements and sizing. Pipe size running to the unit depends on:
• Length of pipe.
• Number of fittings.
• Type of gas.
• Maximum input requirement of all gas boilers in the residence.
Ensure that:
• The gas line connection to the boiler does not apply any weight to the gas valve. NTI recommends using
approved flexible gas piping (if acceptable by local codes) to connect the boiler to the gas supply (See
Figure 7-1 for details).
• You plan the installation so that the piping does not interfere with the vent pipe, or the removal of the valve,
burner, and serviceable components.
• The Boiler shall be installed such that the gas ignition system components are protected from water
(dripping, spraying, rain etc.) during installation and servicing.
• The gas piping is large enough for all the boilers in the home. No appreciable drop in line pressure should
occur when any unit (or combination of units) lights or runs. Use common gas-line sizing practices.
• Always use a pipe-threading compound that is resistant to propane (LP) gas solvent action. Apply sparingly
to all male threads, starting at two threads from the end. Over doping or applying dope to the female end,
can result in a blocked gas line.
• DO NOT TIGHTEN FITTINGS WITHOUT SUPPORTING THE GAS VAL VE as damage to the valve or
blower motor can occur.
• Install a manual “Equipment Shut-Off Valve” as shown in Figure 7-1. Valve must be listed by a nationally
recognized testing lab.
• The gas line piping can safely be removed from the boiler for servicing, by strategically placing the gas line
shutoff and union; see example in Figure 7-1.
• All gas piping, including gas components in the boiler, are checked for leaks using a “Bubble Test”, prior to
operating the boiler.

10.0 BOILER AND HEATING SYSTEM PIPING
The heat exchanger of the Trinity boiler is designed to attain the highest level of heat transfer in a compact
design. To accomplish this, the heating water flows through a series of fin shaped tubes, designed to maximize
the heat transfer area. To maintain the efficient and reliable operation of the heat exchanger, and to avoid heat
exchanger failure, it is critical to ensure the rules and guidelines in this section are followed.
Failure to follow the instructions provided in this section will void the NTI warranty and
may result in property damage, fire, serious injury or death.
Boiler System Preparation
Prior to connecting plumbing to the boiler, flush the entire system to ensure it is free of sediment, flux, solder,
scale, debris or other impurities that may be harmful to the system and boiler. During the assembly of the
heating system, it is important to keep the inside of the piping free of any debris including construction and
copper dust, sand and dirt.
For retrofits, all system piping including radiators, must be cleansed of all build-up including sludge and scale.
All systems, old and new, must be cleansed to remove flux, grease and carbon residue. NTI recommends
cleansing the boiler system with “Fernox F3 Cleaner”. For retrofit applications with heavy limescale and sludge
deposits, a heavier duty cleaner may be required; NTI recommends the use of “Fernox DS-40 System Cleaner”.
For information on performing the cleansing, follow the instructions included with the Fernox DS-40 System
Cleaner. See Table 10-1 for a list of recommended boiler cleansing products.
Table 10-1 Boiler System Cleansers and Corrosion Inhibitors
Application Fernox Product NTI Part # Description
Boiler Water Treatment F1 Protector 83448 Corrosion inhibitor.
Cleanser for new and old systems F3 Cleaner 83449 Removes flux, grease and carbon residue.
Cleanser for Retrofits DS-40 System Cleaner83450 Removes heavy limescale and sludge deposits.
Boiler Water
Pressure - The Trinity boilers are intended solely for use in pressurized closed loop heating systems operating
with a minimum pressure of 15 PSI at the boiler outlet. To obtain the minimum system design pressure, follow
the piping diagrams illustrated in this section.
Oxygen Elimination - This boiler may only be installed in a pressurized closed-loop heating system, free of air
(oxygen) and other impurities. To avoid the presence of oxygen, ensure all of the air is removed from the system
during commissioning via strategically placed adequately sized air-removal devices, located throughout the
heating system. See figures in this section detailing the location of the primary air-removal device required for
the boiler. Immediately repair any leaks in the system plumbing to avoid the addition of make-up water; makeup water provides a source of oxygen and minerals that may lead to heat exchanger failure. Failure to follow
these instructions will result in poor performance, unnecessary wear of system components and premature
failure.
Water Chemistry – The installer of the Trinity Ts boiler must consider the condition of the water in the heating
system. Ensure the condition of the boiler water falls within the following parameters:
• Water hardness – between 3 and 9 Grains/gal.
• PH – between 7.5 and 9.5.
Failure to rid the heating system of the contaminants listed above will void your NTI
warranty and may result in premature heat exchanger failure and property damage.
The “Boiler Application” is not approved for operation in an “open system”, thus it
cannot be used for direct potable water heating or process heating of any kind.
28
Page 29
Ts Series Installation and Operation Instructions│Trinity Ts
Treatment - Boiler water that falls outside of the conditions listed above must be treated with a corrosion
inhibitor. Each Trinity Ts boiler is provided with a bottle of “Fernox F1” corrosion inhibitor, adequate to treat a
26.4 gallon (100 liter) heating system to a minimum required concentration of 0.5%. Systems with greater
volume will require more inhibitor. For information on performing the treatment, follow the instructions
included with the Fernox F1 Protector. See Table 10-1 for a list of recommended boiler system cleansers and
corrosion inhibitors.
Anti-freeze - For systems requiring freeze protection, use only inhibited propylene glycol, specially formulated
for hydronic heating systems; use of other types of antifreeze may be harmful to the system and will void the
warranty. Note: the use of glycol may reduce the usable output capacity of the boiler, thus requiring the unit to
be “down-fired” by limiting the maximum operating capacity and/or the maximum water temperature. NTI
recommends against exceeding 35% concentration of glycol.
Near Boiler Plumbing
Pressure Relief Valve - A Pressure Relief Valve is factory supplied with each unit. Trinity Ts boilers have a
maximum allowable operating pressure of 160PSI. A pressure relief valve with a higher discharge pressure
rating (up to the MAWP of the boiler) may be used as long as the relieving capacity is in excess
input capacity of the boiler.
The pressure relief valve must be installed at the boiler outlet and in the vertical position, as shown in Figure 101, with the drain pipe outlet exiting the side of the pressure relief valve horizontally and elbowing down.
Pressure Gauge – Trinity Ts units come with a factory supplied Pressure Gauge. The pressure gauge must be
installed at the boiler outlet prior to any circulators and in the vicinity of the pressure relief valve. See Figure 10-
1.
Flow Switch / Low Water Cutoff – Trinity Ts boilers are not provided with a LWCO or Flow Switch. Check
with your local authorities for the requirements of these devices prior to installing the boiler. If a Flow Switch is
installed it must be located in series with the boiler and in accordance with the instructions provided with the
flow switch. NTI recommends installing the flow switch in a 1”diameter line.
Refer to Section 3.0 for more information.
To maintain protection, the level of corrosion inhibitor must be monitored periodically
for the correct concentration.
of the maximum
If installed with the incorrect orientation (horizontally with drain pipe out the bottom) the
relief valve may not function properly resulting in property damage or personal injury.
Ensure the discharge of the pressure relief is piped to a location where the steam or water
will not cause property damage or serious injury.
When external safety devices are used, such as a LWCO, Flow Switch, or a Temperature
Limiting Switch, they must be wired as per the instructions provided in this manual.

Boiler System Plumbing
The Trinity Ts boiler uses a low mass heat exchanger that requires a minimum rate of forced water circulation
any time the burner is operating (See Table 10-4 for minimum flow rates). To ensure the minimum flow rate is
attained, the boiler must be installed in a “Primary/Secondary” plumbing configuration utilizing “Closely Spaced
Tees” to de-couple the Boiler-Primary loop from the System-Secondary loop(s). See the examples of
Primary/Secondary Loop configurations in Figures 10-2 and 10-3.
System Components – As well as a Primary/Secondary Loop Configuration utilizing closely spaced tees a
properly installed system will include the following major components identified in Table 10-3 as a minimum.

Air Removal – The boiler and system plumbing layout must be configured to promote the removal of air from
the water. Air vents and bleeders must be strategically placed throughout the system to aid in purging the air
from the system during commissioning of the boiler. The system must also employ the use of a strategically
located air removal device, such as an air scoop or micro-bubbler, designed to remove the air from the water as it
flows through the system.

in close proximity to the water fill and expansion tank.
to remove the air from the system plumbing, even if the air makes it back to the boiler. A strategically located
air removal device must be installed in the system.
Expansion Tank – The expansion tank must be sized in accordance with the water volume of the system as well
as the firing rate of the appliance. It is important to locate the expansion tank, and make-up water fill, on the
inlet side of any circulator in the system, as doing so will guarantee the lowest pressure in the system will be at
least equal to the tank and make-up water pressure. See examples in Figures 10-2 and 10-3.

Indirect Fired Water Heater – When installed as per Figure 10-3, the indirect fired water heater is in series
with the boiler during a demand for DHW. Therefore when using this configuration it is important to use an
Indirect Fired Water Heater that has minimal head loss. Indirect fired water heater head loss must not exceed 4’
at 4 GPM when installed as per Figure 10-3.
Figures 10-2 and 10-3 are examples of plumbing configurations using a single system circulator and multiple
system circulators, respectively.
Figure 10-2: Single System Circulator Configuration - Often used in applications zoned with “Zone Valves”.
During a demand for central heat, the boiler energizes the System Circulator via the Central Heating (CH) pump
output (PUMP C). The System Circulator must be sized to provide adequate circulation throughout the heating
system. During a Domestic Hot Water (DHW) demand, the boiler de-energizes the System Circulator (PUMP
C) and energizes the DHW Circulator (Pump A). With this configuration the Boiler Circulator is the only pump
that causes flow through the boiler and it is powered during any demand via the boiler pump output (PUMP B).
This circulator must be sized according to Table 10-4.
Figure 10-3: Multiple System Circulator Configuration - Often used in applications with “Zone Circulators”.
This configuration requires the installation of a check valve located at each circulator. During a central heating
demand the boiler energizes the Central Heat Circulator via the Central Heat pump out (PUMP C). During a
Domestic Hot Water (DHW) demand, the boiler de-energizes PUMP C and energizes the DHW Circulator
(Pump A). Both Pump A and C, used in this configuration, are responsible for water flow through the boiler and
must be sized according to Table 10-4. Pump output, PUMP B is not used in this configuration.
installation. Concepts not shown include: prevention of thermal-siphoning (heat traps), isolation valves, drain
and purge valves, etc. It is the responsibility of the installing contractor and system designer to determine which
system best meets the need of the installation and to consider all aspects of a proper system design. Contractor
modifications to these instructions may be required, based upon existing piping and system design.
The piping configuration described above requires the Central Heating system and DHW
system to be de-coupled from the “Primary Loop” via closely spaced tees (Figure 10-3).

13.0 CONTROLLER AND DISPLAY
Introduction
The Controller and Display, together, form the control system of the Trinity Ts. All control configuration
parameters are stored in non-volatile memory in the Ts controller. Access to controller status and configuration is
achieved with the display; however, the controller is completely capable of operating with the display
disconnected. Controller factory settings must be field adjusted to suit the application and system requirements.
Please read the following document carefully as factory settings are not configured for a
particular application and may require adjustment in order to satisfy system requirements.
Example: The factory setting for central heat setpoint is 180°F [82°C] which is well suited for many “low masshigh temperature” systems; however, it should be adjusted down for “high mass-low temperature” heating
systems (i.e. 100-130
o
F for infloor heat or 130-160oF for cast iron radiator systems).
It is the responsibility of the installer, a licensed qualified heating technician, to configure and commission the
unit and adjust any parameters required to comply with the application and satisfy the system requirements. See

Holds, Alerts and Lockouts
The controller dynamically reports status by means of codes. These codes are classified as Hold, Alert, and
Lockout and are listed in the Troubleshooting Section of this manual. Refer to Table 16-3 for Hold and Lockout
codes and Table 16-4 for a list of Alert codes.
In a Hold state the controller is waiting for an event to occur, such as closing of the air proving switch. Typically
no manual intervention is needed; Hold conditions are transient in nature and a normal part of appliance
operation. Alert codes are used to report non-critical events that do not require manual intervention.
Lockouts occur when a safety limit is exceeded, e.g. stack temperature limit of 220°F [104°C], or the air proving
switch cannot prove. Lockouts force burner shutdown and require manual action to restore the appliance to
normal operation. A Lockout persists until a) the “Reset” button on the display is pressed and released; b) the
Reset button on the controller is pressed and released; c) power to the appliance is turned off and turned on
again.

16.0 TROUBLESHOOTING
Servicing the Boiler
• Disconnect or shut off all energy sources to the boiler: 120VAC power, water and gas.
• Identify and mark wires before disconnecting or removing them.
• Never bypass electrical fuses or limit devices except temporarily for testing.
• Use proper personal protective equipment (PPE) i.e. eye protection, safety footwear.
These procedures should only be performed by qualified service personnel, when abnormal operation of the
boiler is suspected. The boiler incorporates a sophisticated microprocessor based control which normally
responds appropriately to varying conditions. If the boiler operation appears to be incorrect, or it is not
responding at all to a demand for heat, the following is suggested to determine and correct the problem.
Resistance (ohms) and Continuity.
Check 120VAC and 24VAC at the Boiler
First, verify the following:
• There is 120V being supplied to the boiler:
o The circuit breaker in the electrical panel supplying power to the boiler is not tripped.
o The service switch (if applicable) is in the ON position.
• There is a heat call from the thermostat:
o Verify 24VAC to thermostat.
o The thermostat is placed at a sufficiently high setting to create a call for heat to the boiler.
To check for the presence of 120VAC and 24VAC at the boiler follow this procedure:
• Remove the boiler front cover.
• 120VAC
o Disconnect the spark cable from the burner door.
o Remove the control panel cover. First loosen the two #8 hex-head sheet metal screws securing the cover
to the control panel. Lift the cover off and remove it from the unit, this will expose the field wiring
barrier strip. Note: once the cover is partially removed the spark cable can be disconnected from the
controller.
oWith an AC voltmeter set on the appropriate scale, measure the voltage across the L1 and L2 terminals
(terminals 12 and 13).
oIf 120VAC is not detected, check the electrical service as suggested above. If the service is verified,
inspect the circuit wiring from the panel to the boiler for broken or disconnected conductors.
oIf 120VAC is detected, turn power off to the boiler at the service switch and check the 120VAC fuse
located on the right side of the control panel; refer to Figure 16-1 – replace if necessary.
• 24VAC (only check if 120VAC supply is verified).
o Disconnect the spark cable from the burner door.
o Remove the control panel cover. First loosen the two #8 hex-head sheet metal screws securing the cover
to the control panel. Lift the cover off and remove it from the unit, this will expose the field wiring
barrier strip. Note: once the cover is partially removed the spark cable can be disconnected from the
controller.
oWith an AC voltmeter set on the appropriate scale, measure the voltage between the R and COM
terminals (terminals 1 and 2).
oIf 24VAC is not detected, check the 24VAC fuse located at the transformer in the control panel; refer to
Figure 16-1 – replace if necessary.
Observe the following precautions when servicing the boiler. Failure to comply with
these may result in fire, property damage, serious injury or death.
Before undertaking any troubleshooting procedures it is highly recommended to have
available a digital multimeter(s) capable of measuring AC and DC volts, Amperes,
