BEFORE INSTALLING
WHEN SERVICING BOILER
To avoid electric shock, disconnect electrical supply before performing maintenance.
To avoid severe burns, allow boiler to cool before performing maintenance.
BOILER OPERATION
Do not block flow of combustion or ventilation air to boiler.
Should overheating occur or gas supply fail to shut off, do not turn off or disconnect electrical supply to circulator. Instead, shut off the gas supply at a location external to the appliance.
Do not use this boiler if any part has been under water. Immediately call a qualified service technician to inspect the boiler and to replace any part of the control system and any gas control that has been under water.
BOILER WATER
If you have an old system with cast iron radiators, thoroughly flush the system (without boiler connected) to remove sediment. The high-efficiency heat exchanger can be damaged by build-up or corrosion due to sediment. HTP recommends a suction strainer in this type of system.
Do not use petroleum-based cleaning or sealing compounds in boiler system. Gaskets and seals in the system may be damaged. This can result in substantial property damage.

B. HOW BOILER OPERATES
Elite Heating Boiler
®
Condensing Technology is an intelligent system that delivers highly effi­cient hydronic heating, while maximizing effi­ciency by measuring the data parameters of your heating system. Outlined below are the features of the system and how they operate:
1. Stainless Steel Heat Exchanger – The highly
efficient Elite Heating Boiler
®
Stainless Steel Heat exchanger is designed to use the cold return water from the system and extract the last bit of heat before it is exhausted.
2. Modulating Combustion System – The combustion system will modulate the output of the burner during operation to match the system demand and achieve the control set
point while in operation. The set point can change by internal or external signals which enhance the overall performance of the system.
3. Control – The integrated control system monitors the system and regulates the fan speed to control the boilers output. This allows the boiler to deliver only the amount of heated energy required and nothing more. This control can be set up to monitor outdoor temperature through an outdoor sensor to regulate the set point of the boiler. The system can be further enhanced by connecting up to an indirect water heater to provide domestic hot water.
The control can regulate the output of multiple boilers through its cascade system function. The cascade system is capable of connecting up to eight boilers together in such a way that they function as one boiler system. This allows for greater turn down ratios and provides systematic control of the multiple boilers in an installation to minimize downtime and maximize efficiency.
The cascade system works by establishing one boiler as the master and the other connected boilers as followers. The master boiler will have a cascade system sensor and a cascade pump connected to it in addition to its own boiler pump. The follower boilers will have their own individual pump connected to

CAUTION
Consider piping and installation when determining boiler location.
n
CAUTION
NEVER use automotive or standard glycol antifreeze, ethylene glycol made for hydronic systems. Use only inhibited propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is toxic and can attack gaskets and seals used in hydronic systems.
Continual fresh make-up water will reduce boiler life. Mineral buildup in the heat exchanger reduces heat transfer, overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen carried in by make-up water can cause internal corrosion in system components. Leaks in boiler or piping must be repaired at once to prevent make-up water.

each follower boiler.
4. Text Display and Operational Led light
Indicators – The display allows the user to
change the system parameters and monitor the system outputs.
5. Gas Valve – The gas valve senses suction from the blower allowing gas to flow only if the gas valve is powered and combustion air is flowing.
6. All Metal Integrated Venturi – Controls the air and gas flow into the burner.
7. Burner – Constructed of high grade stainless steel, the burner uses premixed air and gas fuel and provides a wide range of firing rates.
8. Spark Ignition – The burner is ignited by applying a high voltage through the system spark electrode. This causes the spark from the electrode to ignite the mixed gas off of the burner.
9. Supply Water Temperature Sensor – This sensor monitors the boiler outlet water temperature (System Supply). The control adjusts the boiler firing rate so the supply temperature will match the boiler set point.
10. Return Water Temperature Sensor – This sensor monitors the boiler return water temperature (System Return).
11. Flue Sensor – Monitors flue temperature and adjusts firing rate.
12. Temperature and Pressure Gauge – Allows the user to monitor the system temperature and pressure.
13. Electrical field connections with terminal strips – The electrical cover allows easy
access to the line voltage and low voltage terminals strips which are clearly marked to facilitate wiring of the boiler.
14. Condensation Collection System – This boiler is a high efficiency appliance, therefore the boiler will produce condensate. The collection system has a float switch which monitors the condensation level and prevents condensation from backing up into the combustion system. Inside the collection system there is a built in trap which seals the combustion system from the connected drain. This condensate should be neutralized to avoid damage to the drainage system or piping.
15. Outdoor Sensor – The outdoor sensor will
monitor the outdoor temperature and adjust the unit’s set point to provide greater efficiency.
16. 0-10 Volt Input – Allows Installer to connect to a BMS (Building Management System) to control the boiler.
17. Condensate Flue Check System – The Check system prevents exhaust from the heat exchanger from backing up into cabinet.
18. Pump Service Mode – Allows manual operation of pumps to commission system and check pump operation.
19. The Vision II system allows the user to supply mixed temperatures in up to eight zones when connected to the Elite Boiler. The Vision II system controls the temperature to each zone by employing three way mixing valves. The Vision II also controls the output temperature of the Elite Boiler to assure accurate temperature delivery to all the connected zones.

CAUTION
DO NOT install automatic air vents on closed­type expansion tank systems. Air must remain in the system and return to the tank to provide an air cushion. An automatic air vent would cause air to leave system, resulting in water­logging the expansion tank.
n
CAUTION
DO NOT use the boiler circulator in any location other than the ones shown in this manual. The boiler circulator location is selected to ensure adequate flow through the Elite Heating Boiler®. Failure to comply to this caution could result in unreliable performance and nuisance shut downs from insufficient flow.
CAUTION
Undersized expansion tanks cause system water to be lost from the relief valve causing makeup water to be added. Eventual boiler failure can result due to excessive make-up water addition. This type of failure is NOT covered by warranty.

isolated from the boiler loop by the primary/secondary connection.
2. Size the piping and components in the space heating system using recognized design methods.
F. HYDRONIC PIPING WITH CIRCULATORS,
ZONE VALVES AND MULTIPLE BOILERS
The Elite Heating Boiler®is designed to function in a closed loop Hydronic System. We have included a Temperature and Pressure Gauge that allows the user to monitor the system pressure and outlet temperature from the Elite Heating Boiler
®
. It is im-
portant to note that the Elite Heating Boiler
®
has a minimal amount of pressure drop and must be cal­culated when sizing the circulators. Each Elite Heating Boiler
®
installation must have an air elim­ination device that will remove air from the system. Install the Elite Heating Boiler
®
so the gas ignition system components are protected from water (dripping, spraying, etc.). Allow clearance for basic service of boiler circulator, valves and other com­ponents. Observe the minimum 1” clearance around all un-insulated hot water pipes when openings around pipes are not protected by non-
combustible materials. On an Elite Heating Boiler
®
installed above radiation level, some states and local codes require a low water cut off device which is optional on the Elite Heating Boiler
®
. Check with local codes for additional requirements. If the Elite Heating Boiler
®
supplies hot water to heating coils in air handler units, flow control valves or other devices must be installed to prevent grav­ity circulation of boiler water in the coils during the cooling cycle. Chilled water medium must be piped in parallel with the boiler. Freeze protection for new or existing systems must use glycol that is specif­ically formulated for this purpose. It will include in­hibitors that will prevent the glycol from attacking the metallic system components. Make certain that the system fluid is checked for the correct glycol concentration and inhibitor level. The system should be tested at least once a year and as rec­ommend by the producer of the glycol solution. Allowance should be made for the expansion of the glycol solution in the system piping. Example: 50% by volume glycol solution expands 4.8% in volume for the temperature increase from 32 F to 180 F, while water expands 3% with the same tem­perature rise.

Basic steps are listed below, with Illustration, that will guide you through the installation of the Elite Heating Boiler
®
.
1. Connect the system return marked “Boiler Return”.
2. Connect the system supply marked “Boiler Supply”.
3. Install a purge and balance valve or shut off valve and drain on the system return to purge air out of each zone.
4. Install a back flow preventer on the cold feed make-up water line.
5. Install a pressure reducing valve on the cold feed make-up water line, (15 PSI nominal on the system return). This boiler has a maximum working pressure of 160 PSI. You may order a higher pressure relief valve kit from the factory. Check temperature and pressure gauge when operating. It should read minimum pressure of 12 PSI.
6. Install a circulator as shown in piping details
(this section). Make sure the circulator is properly sized for the system and friction loss.
7. Install an expansion tank on the system supply. Consult the expansion tank manufacturer’s instruction (see part 5, section D for water volume) for specific information relating to expansion tank installation. Size the expansion tank for the required system volume and capacity.
8. Install an air elimination device on the system supply.
9. Install a drain valve at the lowest point of the system. Note: The Elite Heating Boiler
®
can not be drained completely of water without purging the unit with an air pressure 15 PSI.
10. The relief valve, temperature & pressure gauge are included in the accessory kit with the Elite Boiler Accessory Kit. A pipe discharge line should be installed 6” above the drain in the event of a pressure relief. The pipe size must be the same size as the relief valve outlet. NEVER BLOCK THE OUTLET
OF THE SAFETY RELIEF VALVE.

I. FILL AND PURGE HEATING SYSTEM
Attach the hose to balance and purge hose connector or drain valve and run hose to nearest drain.
Close the other side of the balance and purge valve or the shut off valve after the drain.
Open the first zone balance and purge or drain valve to let water flow out the hose. If zone valves are used, open the valves one at a time manually. (Note: You should check zone valve manufacturer’s instructions prior
to opening valves manually, so as not to damage the zone valve.)
Manually operate fill valve regulator. When water runs out of the hose you will see a steady stream of water without bubbles. Close the balance and purge valve or drain to stop the water from flowing. Disconnect the hose and connect it to next zone to be purged.
Repeat this procedure for additional zones (one at time).

Upon completion, make sure that the fill valve is in the automatic position and each zone balance and purge or shut off is in an open position and zone valves are positioned for automatic opera­tion.
1. Glycol in hydronic applications which is specially formulated for this purpose includes inhibitors that prevent the glycol from attacking metallic system components. Make certain that the system fluid is checked for the correct glycol concentration and inhibitor level.
2. The glycol solution should be tested at least once a year and as recommended by the glycol manufacturer.
3. Anti-freeze solutions expand more than water. For example a 50% by volume solution expands 4.8% in volume for a temperature increase from 32° F to 180° F, while water expands 3% with the same temperature rise. Allowances must be made for this expansion in the system design.
4. A 30% mixture of glycol will result in a BTU output loss of 15% with a 5% increase in head against the system circulator.
5. A 50% mixture of glycol will result in a BTU output loss of 30% with a 50% increase in head against the system circulator.
J. ZONING WITH ZONE VALVES
1. Connect the boiler to the system as shown in Piping Details (Part 5) when zoning with zone valves. The primary/secondary piping shown ensures the boiler loop will have sufficient flow. It also avoids applying the high head of the boiler circulator to the zone valves.
2. Connect DHW (domestic hot water) piping to indirect storage water heater as shown in Piping Details (Part 5).
K. ZONING WITH CIRCULATORS
1. Connect the boiler to the system when using circulator zoning as shown in the Piping Details when zoning with circulators. NOTE: The boiler circulator cannot be used for a zone. It must supply only the boiler loop.
2. Install a separate circulator for each zone.
3. Connect DHW (domestic hot water) piping to indirect storage water heater as shown in the Piping Details (Part 5).
L. MULTIPLE BOILERS
1. Connect multiple boilers as shown in the Piping Details (Part 5).
2. All piping shown is reverse return to assure balanced flow throughout the connected boilers.
3. Each connected boiler must have its own circulator pump to assure adequate flow.
4. Connect DHW (domestic hot water) piping to indirect storage water heater as shown in the Piping Details (Part 5).
5. The system flow (secondary loop) must be greater than the boiler’s primary loop flow.
n
CAUTION
For installations that incorporate standing iron radiation and systems with manual vents at the high points. Follow the previous section and starting with the nearest manual air vent, open the vent until water flows out, then close the vent. Repeat the procedure, working your way toward furthest air vent. It may be necessary to install a basket strainer in an older system where larger amounts of sediment may be present. Annual cleaning of the strainer may be necessary.
n
WARNING
Use only inhibited propylene glycol solutions which are specially formulated for hydronic systems. Ethylene glycol is toxic and can attack gaskets and seals used in hydronic systems. Glycol mixtures should not exceed 50%.
n
CAUTION
It is highly recommended that you carefully follow the glycol manufacturer’s recommended concentrations, expansion requirements and maintenance recommendations (pH additive breakdown, inhibitor reduction, etc.). You must carefully calculate the additional friction loss in the system as well as the reduction in heat transfer co-efficients.

PIPE LOCATION
NOTE: SEE ADDITIONAL REQUIREMENTS FOR MASSACHUSETTS IN THE BACK OF THIS MANUAL.
1. Determine exhaust vent location:
• Total length of vent may not exceed the limits specified in Part 6 Section E.
The vent piping for this boiler is approved for zero clearance to combustible construction.
See Venting Details within this section of clearances for location of exit terminals of direct-vent venting systems.
• Avoid terminating exhaust vents near shrubs, air conditioners or other objects that will obstruct the exhaust stream.
• The flue products coming from the exhaust vent will create a large plume when the boiler is in operation. Avoid venting in areas that will affect neighboring buildings or be considered objectionable.
The boiler vent system shall terminate at least 3 feet (0.9 m) above any forced air intake located within 10 ft (3 m). Note: this does not apply to the combustion air intake of a direct-vent appliance.
Provide a minimum of 1 foot distance from any door, operable window, or gravity intake into any building.
Provide a minimum of 1 foot clearance from the bottom of the exhaust above the expected snow accumulation level. Snow removal may be necessary to maintain clearance.
Provide 4 feet horizontal clearance from electrical meters, gas meters, gas regulators, relief equipment, exhaust fans and inlets. In no case shall the exit terminal be above or below the aforementioned equipment unless the 4 foot horizontal distance is maintained.
Do not locate the boiler exhaust over public walkways where condensate could drip and/or freeze and create a nuisance or hazard.
When adjacent to a public walkway, locate exit terminals at least 7 feet above grade.
Do not locate the exhaust directly under roof overhangs to prevent icicles from forming.
Provide 6 feet of clearance from the inside corner of vertical walls, chimneys, etc., as well as horizontal corners created by roof overhangs.
2. Determine air intake vent locations.
Provide 1 foot of clearance from the bottom of the intake air vent and the level of maximum snow accumulation. Snow removal may be necessary to maintain clearances.
Do not locate the intake air vent in a parking area where machinery may damage the vent.
Follow required minimum clearances located in Fig. 6-3, 6-4, 6-5.
3. Determine location of Condensate Piping
This boiler is a high efficiency appliance, therefore the boiler produces condensate. Condensate is a by-product of the boiler combustion process. A condensate collec­tion system with an internal float switch
n
WARNING
You must not use “B” Vent in an exhaust application. ‘B’ vent is for intake applications only. Failure to do so will result in serious injury or death.
n
WARNING
Both exhaust and intake air vents must exit from the same side of the building to assure correct appliance operation.
n
WARNING
You must insert the provided intake and exhaust screen at your vent terminations to prevent blockage caused by birds or debris.
Page 29
28
Boiler Manual
CAUTION
It is very important that the condensate piping be no smaller than ¾” and you must use a tee at the condensate connection with the branch vertically up and open to the atmosphere so it will not cause a vacuum that could obstruct the flow of condensate from the boiler. The condensate piping should also be properly supported with pipe supports to prevent sagging and to maintain the pitch of the piping.
4. Condensate Neutralization
The condensate from the boiler is slightly acidic with a pH of 3.2 – 4.5 Heat Transfer Products, Inc. recommends neutralizing the condensate with a Condensate Neutralizer Kit p/n 7450P-212 (EL-80/110/150/220) p/n 7350P­611 (EL-299/399) that can be added to your system to avoid long term damage to the drainage system and to meet local code requirements. The neutralizer kit is connected to the drain system and contains marble chips that will neutralize the pH level of the water vapor. The neutralizer should be checked at least once a year and the marble chips should be replenished if necessary. When replacing the marble chips, they should be no smaller than ½” to avoid blockage in condensate piping. (Refer to Fig. 6-1 and 6-2 for piping of the Condensate neutralizer.)
PART 6: VENTING, COMBUSTION AIR & CONDENSATE REMOVAL (CONTINUED)
monitors the condensate level to prevent it from backing up into the combustion sys­tem. There is a ¾” sweat connection provid­ed to connect the outlet of the collection system to a drain or condensate pump. (See Table 6-3 for approved condensate piping material)
Page 30

Boiler Manual
PART 6: VENTING, COMBUSTION AIR & CONDENSATE REMOVAL (CONTINUED)
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 boiler tee, resulting in potential water damage to property.
NOTICE
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 Elite Heating Boiler®will be slightly acidic (typically with a pH from 3.2 to
4.5). Install a neutralizing filter if required by local codes.

2. The total combined equivalent length of exhaust vent and intake air pipe should not exceed 200 feet.
a. The equivalent length of elbows, tees,
and other fittings are listed in the Friction Loss Table 6-8.
*Friction loss for long radius elbow is 1 foot less.
b. For example: If the exhaust vent has two
short 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 short 90° elbows, one 45° elbow and 10 feet of PVC pipe, the following calculation applies:
Intake Air Vent Pipe Equivalent Length = (2x5)+1+10=21 feet
c. The intake air vent pipe and the exhaust
vent are intended to penetrate the same wall or roof of the building.
d. You should keep an equivalent length
between the intake air vent pipe and the exhaust vent. The minimum combined equivalent length is 16 to 32 maximum combined equivalent feet.
e. The size of the venting can also be
reduced in order to accommodate an existing vent sizes.
When reducing down to a 2” vent from a 3” vent or down to a 3” vent from 4”, the combined length shall not exceed an equivalent of 100 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 16 to 32 maximum combined equivalent feet from the boiler on both the intake and exhaust equally.
a. The maximum equivalent length for the
increased diameter vent pipes is 275 feet, which includes the combined 32 feet from the boiler, 16 ft. (inlet) + 16 ft. (exhaust) = 32 ft. combined with transition total of 245 ft. upsize piping for longer vent runs.
G. EXHAUST VENT AND INTAKE AIR PIPE
INSTALLATION
1. Use only solid PVC, or CPVC schedule 40 or 80 pipe and AL294C Stainless Steel. FOAM CORE PIPING IS ONLY ALLOWED FOR INTAKE PIPING.
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. Refer to the Venting Table 6-4.

PART 6: VENTING, COMBUSTION AIR & CONDENSATE REMOVAL (CONTINUED)
4. Horizontal lengths of exhaust vent must slope back towards the boiler 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. All vent pipes must be glued, properly supported and the exhaust must be pitched a minimum of ¼” per foot back to the boiler to allow drainage of condensate. The condensate drain piping should be a minimum of ¾” PVC rigid piping, pitched at a minimum of ¼” per foot away from the boiler. (See Fig. 6-1, 6-2)
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. When placing support brackets on vent piping, the first bracket must be within 1 foot of the appliance and the balance at 4 foot intervals on the vent pipe. The boiler venting must be readily accessible for visual inspection for the first three feet of the boiler.
6. Do not use the boiler to support any piping.
7. A screened straight coupling is provided with the boiler for use as an outside exhaust termination.
8. A screened inlet air tee is provided with the boiler to be used as an outside intake termination.
H. HEATER REMOVAL FROM A COMMON
VENT SYSTEM
At the time of removal of an existing 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
Note: For Canadian Installations, it is required that Non Metallic Vent Installations conform to ULC S636. Where plastic venting is not allowed, HTP recommends AL294C Stainless Steel Venting be used for Exhaust venting installa­tions and “B” vent for intake air.
Please refer to 6-7 below for U.L. Approved Stainless Steel Vent Adapters.

PART 7: GAS PIPING
A. GAS CONNECTION
The gas supply shall have a maximum inlet pressure of less than 14" w.c. (3.5 kPa), and a minimum of 3.5" w.c. (.87 kPa). The entire piping system, gas meter and regulator must be sized properly to prevent pressure drop greater than
0.5" (.12 kPa) as stated in the National Fuel Gas Code. This information is listed on the rating label.
The gas connection on the Elite Heating Boiler
®
is 3/4” for the EL-80/110/150 and 1” for the EL-220/299/399. It is mandatory that this fitting is used for connection to a field fabricated drip leg as shown in the illustration above per the National Fuel Gas Code. You must ensure that the entire gas line to the connection at the Elite Heating Boiler
®
is no smaller than the unit sup-
plied connection. Once all the inspections have
n
WARNING
Failure to follow all precautions in this section could result in fire, explosion or death!
n
WARNING
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. You must not do a gas conversion on this boiler without an approved gas conversion kit. All gas connections must be approved by the local gas supplier, or utility in addition to the governing authority, prior to turning the gas supply on.
been performed, the piping must be leak tested. If the leak test requirement is a higher test pres­sure than the maximum inlet pressure, you must isolate the Elite Heating Boiler
®
from the gas line. In order to do this, you must shut the gas off using factory and field-installed gas cocks. This will prevent high pressure. 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" w.c. (3.5 kPa), the gas valve must be replaced. Never use an open flame (match,
lighter, etc.) to check gas connections.
B. GAS PIPING
1. Run the gas supply line in accordance with all
applicable codes.
2. Locate and install manual shutoff valves in ac-
cordance with state and local requirements.
3. In Canada, the Manual Shutoff must be
identified by the installing contractor.
4. It is important to support gas piping as the
unit is not designed to structurally support large amount of weight.
5. Purge all gas lines thoroughly to avoid start
up issues with air in the lines.
6. Sealing compound must be approved for gas
connections. Care must be taken when applying compound to prevent blockage or obstruction of gas flow which my effect the operation of the unit.

C. CHECK INLET GAS PRESSURE
The gas valve is equipped with an inlet gas pres­sure tap that can be used to measure the gas pressure to the unit. To check gas pressure, per­form the steps listed below:
1. Before you connect to the inlet pressure, you must shut off the gas and electrical power to unit.
2 Loosen the pressure tap with a small screw-
driver. Refer to Figures 7-2 for location.
3. Each unit is equipped with a needle valve that will accept a 5/16 ID hose to connect to a digital manometer or liquid gauge to measure incoming pressure from 0-35” w.c. See Figure 7-1.
4. Turn on the Gas and Power up the unit.
5. Put the unit into manual test mode (Details on test mode are in Part 11 Section B). In service mode, monitor pressure to assure it does not drop below 1 inch from its idle reading. If Gas Pressure is out of range or pressure drop is excessive, contact the gas utility, gas supplier, qualified installer or service agency to determine correct action that is needed to provide proper gas pressure to the unit. If Gas Pressure is within normal range proceed to Step 6.
6. Exit test mode, then turn power off and shut off gas supply at the manual gas valve before
disconnecting the hose from the gas monitoring device. Tighten the screw on the pressure tap tightly and turn gas on and checks for leaks with soapy solution.
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 pressure drop. 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" w.c. (.87 kPa), the meter, regula­tor or gas line may be 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" (.87 kPa) and 14" (3.5 kPa) during stand-by (static) mode and while in operating (dynamic) mode. If an in-line regula-
tor is used, it must be a minimum of 10 feet from the Elite Heating Boiler
®
. 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 notice-
able in NEW LP installations and also in empty tank situations. This situation can also occur when a utility company shuts off service to an area to provide maintenance to their lines. This gas valve must not be replaced with a conven­tional gas valve under any circumstances.
n
WARNING
Never use an open flame (Match or Lighter) to check for Gas leaks. Use A soapy solution to test gas connection for leaks. Failure to use soapy solution test or check gas connection for leaks can cause substantial property damage, severe personal injury or death.
NOTICE
CSA or UL listed Flexible gas connections can be used when installing The Elite Heating Boiler®. Flexible gas connections have different capacities and must be sized correctly for the connected boiler firing rates. Consult with the flex line supplier to assure the line size is adequately sized for the job. Follow local codes for proper installation and service requirements.

1. National Electrical Code and any other national, state, provincial or local codes or regulations.
2. In Canada, CSA C22.1 Canadian Electrical Code Part 1, and any local codes.
B. FIELD WIRING
All connections made to the Elite Heating Boiler®in the field are done inside the electrical junction box located on the side of the unit. The electrical junction box is located on the left side of Elite Heating Boiler
®
. Multiple knockout loca­tions are available to route field wires into and out of the electrical junction box.
The control used in the Elite Heating Boiler
®
series of boilers is capable of directly controlling 2 pumps when in standard mode and 3 pumps when configured as a cascade master boiler. When configured as a standard unit, each pump output can provide a maximum of 3 amps at 120 volts. If pumps used require more than this amount of power, an external contactor or motor starter is needed. If the boiler is config­ured as a cascade master, the system pump out­put is a dry contact output capable of switching 5 amps at 120 volts in addition to the boiler pump and DHW pump outputs sourcing 3 amps each.
The electrical junction box has separate, clearly marked terminal strips for line voltage and low voltage wiring. Special jacks are provided for trouble-free cascade system wiring using stan­dard CAT3 or CAT5 patch cables.
C. LINE VOLTAGE WIRING FOR
STANDARD BOILER
1. Connect the incoming power wiring to the line voltage terminal strip in the electrical junction box at terminals 120V, Neutral, Ground (shown in figure 8-1.)
2. A line voltage fused disconnect switch may be required to be externally mounted and connected according to local codes that may apply.
3. Connect the central heating pump as shown in Figure 8-1 to the terminals marked BOILER HOT, BOILER NEUT, BOILER GND. The connections shown are suitable for a maximum continuous pump draw of 3 amps at 120 volts. If a the pump requires more current or voltage other than the 120 volts supplied, an external motor starter or contactor will be required.
4. If using DHW, connect the domestic hot water pump as shown in Figure 8-1 to the terminals marked DHW HOT, DHW NEUT, DHW GND. The connections shown are suitable for a maximum continuous pump draw of 3 amps at 120 volts. If a pump that requires more current or voltage other than 120 volts supplied, an external motor starter or contactor will be required.

devices such as television sets that could influence the ability of the thermostat to measure room temperature.
3. If the thermostat is equipped with an anticipator and it is connected directly to the Elite Heating Boiler®, the anticipator should be set at .1 amps. If the thermostat is connected to other devices, the anticipator should be set to match the power requirements of the device it is connected to. See the instruction manual of the connected devices for further information.
F. OUTDOOR SENSOR
1. There is no connection required if an outdoor sensor is not used in this installation.
3. Use a minimum 22 AWG wire for runs of 100 feet or less and minimum 18 AWG wire for runs of up to 150 feet.
4. Mount the outdoor sensor on an exterior surface of the building, preferably on the north side in an area that will not be affected by direct sunlight and will be exposed to varying weather conditions. NOTE: Follow instructions provided with the sensor for correct mounting instructions.
G. INDIRECT SENSOR
1. There is no indirect sensor connection required if an indirect water heater is not used in the installation.
2. The Elite Heating Boiler
®
will operate an indirect fired water heater with either a thermostat type aquastat installed in the indirect tank or an HTP 7250P-325 tank sensor. When a tank sensor is used, the Elite Heating Boiler
®
control will automatically detect its presence and a demand for heat from the indirect water heater will be generated when the tank temperature falls below the user set point by more than the user selectable offset. The demand will continue until the sensor measures that the indirect water heater temperature is above the set point.
3. Connect the indirect tank sensor (7250P-325) to the terminals marked DHW SENSOR (shown in figure 8-1) in the electrical junction box.
H. OPTIONAL 0-10 VOLT BUILDING
CONTROL SIGNAL
1. A signal from a building management system may be connected to the Elite Heating Boiler
®
to enable remote control. This signal should be a 0-10 volt positive-going DC signal. When this input is enabled using the installer menu, a building control system can be used to control either the set point temperature or the heat output of the Elite Heating Boiler
®
. The control interprets the 0-10 volt signal as follows; when the signal is between 0 and 1 volt, the Elite Heating Boiler
®
will be in stand­by mode, not firing. When the signal rises above 1 volt, the Elite Heating Boiler
®
will ignite. As the signal continues to rise towards its maximum of 10 volts, the Elite Heating Boiler
®
will increase either in set point temperature or firing rate depending on the setting of function 17 in the installer menu. See Part 11 for details on the setting of functions 16 and 17 for this option.
2. Connect a building management system or other auxiliary control signal to the terminals marked 0-10 VOLT + and 0-10 VOLT – in the electrical junction box (shown in figure 8-1) Caution should be used to ensure that the 0­10 VOLT + connection does not become connected to ground.
I. OPTIONAL UL353 LOW WATER CUT-OFF
INTERFACE KIT
If an optional UL 353 Low Water Cut-Off (LWCO) Interface Kit is used, the control box of the kit should be mounted to the left side of the boiler cabinet near the low water cut-off probe, which is located on the outlet nipple of the boiler.
Follow the complete instructions included in the kit for proper installation.

communication bus between each of the boilers. These cables are readily available at any office supply, computer, electronic, department or discount home supply store in varying lengths. If you possess the skills you can also construct custom length cables.
2. It is recommended to use the shortest length cable that will reach between the boilers and create a neat installation. Do not run unprotected cables across the floor where they may become wet or damaged. Avoid running communication cables parallel and close to or against high voltage (120 volt or greater) wiring. HTP recommends that the maximum length of communication bus
cables not exceed 200 feet.
3. Route the communication cables through one of the knockouts in the cabinet.
4. Connect the boilers in a daisy chain configuration as shown below. It is best to wire the boilers using the shortest wire runs rather than trying to wire them in the order that they are addressed. The communication bus jacks on the customer connection panel are interchangeable so you can use either one or both in any order to connect the cable. If you have connected the boilers to each other properly, two of the boilers will have one open connection port on them.

2. If you are using an indirect fired water tank connected directly to the follower boiler connect the pump for it to the DHW, HOT DHW NEUT, and DHW GND terminals.
An alarm bell or light can be connected to the alarm contacts of the follower boiler. The nor­mally closed alarm contact may be used to turn a device off if the boiler goes into lockout mode. The alarm contacts are rated 5 amps at 120 VAC.
To connect an alarm device, connect the power
for the device to the ALARM COM terminal. Connect the alarm device hot wire to the ALARM NO terminal. Connect the neutral or return of the alarm device to the neutral or return of the power for the alarm device.
To connect a device that should be powered off during a boiler lockout condition, follow the same instructions as above except use the ALARM NC terminal rather than the ALARM NO terminal.
Note that in a cascade system the alarm output of the boiler addressed as #1 will also be active if the master boiler has a lockout condition. The alarm output of boilers addressed as 2-7 will only activate an alarm if a lockout condition occurs on that specific boiler.

PART 9. START-UP PREPARATION
To assure good extended service life, it is recommended that you test your water quality prior to installation. Listed below are some guidelines.
A. CHECK/CONTROL WATER CHEMISTRY
Water pH between 6.0 and 8.0
1. Maintain boiler water pH between 6.0 and 8.0. Check with litmus paper or have it chemically analyzed by a water treatment company.
2. If the pH differs from above, consult local water treatment company for treatment needed.
Hardness less than 7 grains.
1. Consult local water treatment companies for unusually hard water areas (above 7 grains hardness).
Chlorine concentration less than 200 ppm
1. Using chlorinated fresh water should be acceptable since drinking water chlorine levels are typically less than 5 ppm.
2. Do not connect the boiler to directly heat a swimming pool or spa water.
3. Do not fill boiler or operate with water containing chlorine in excess of 200 ppm.
Clean system to remove sediment
1. You must thoroughly flush the system (without boiler connected) to remove sediment. The high-efficiency heat exchanger can be damaged by build up or corrosion due to sediment build up.
2. For zoned systems, flush each zone sepa­rately through a purge valve. (If purge valves and isolation valves are not already installed, install them to properly clean the system.)
3. Flush system until water runs clean and you are sure piping is free of sediment.
Test freeze protection fluid
1. For systems using freeze protection fluids,
follow fluid manufacturer’s instructions to verify inhibitor level and that other fluid characteristics are satisfactory.
2. Freeze protection fluid must be replaced period­ically due to degradation of inhibitors over time. Follow all fluid manufacturer’s instructions.
B. FREEZE PROTECTION (WHEN USED)
1. Determine the freeze protection fluid quantity using total system water content, following fluid manufacturer’s instructions. Remember to include expansion tank water content.
2. Local codes may require back flow preventer or actual disconnect from city water supply.
3. When using freeze protection fluid with automatic fill, install a water meter to monitor water makeup. Freeze protection fluid may leak before the water begins to leak, causing concentration to drop, reducing the freeze protection level.
C. FILL AND TEST WATER SYSTEM
1. Fill the system only after ensuring the water meets the requirements of this manual.
2. Close the manual and automatic air vents and boiler drain valve.
3. Fill to the correct system pressure. Correct pressure will vary with each application.
a. Typical cold water fill pressure for a
residential system is 12 psi.
b. Pressure will rise when boiler is turned
on and system water temperature increases. Operating pressure must never exceed the relief valve pressure setting.
n
WARNING
NEVER use automotive or standard glycol antifreeze. Do not use ethylene glycol made for hydronic systems. Use only freeze-prevention fluids certified by fluid manufacturer as suitable for use with stainless steel boilers, verified in the fluid manufacturer’s literature.
Thoroughly clean and flush any system that has has used glycol before installing the new boiler.
Provide the boiler owner with a material safety data sheet (MSDS) on the fluid used.
n
WARNING
Do not use petroleum-based cleaning or sealing compounds in the boiler system. Damage to elastomer seals and gaskets in the system could occur, resulting in substantial property damage.
Page 51

Boiler Manual
PART 9. START-UP PREPARATION (CONTINUED)
4. At initial fill and during boiler startup and testing, check system thoroughly for any leaks. Repair all leaks before proceeding further.
5. The system may have residual substances that could affect water chemistry. After the system has been filled and leak tested, verify that water pH and chlorine concentrations are acceptable by sample testing.
D. PURGE AIR FROM WATER SYSTEM
1. Purge air from system:
a. Connect a hose to the purge valve and
route hose to an area where water can drain and be seen.
b. Close the boiler or system isolation valve
between the purge valve and fill
connection to the system. c. Close zone isolation valves. d. Open quick-fill valve on cold water make-
up line. e. Open purge valve. f. One zone at a time, open the isolation
valves. Allow water to run through the
zone, pushing out the air. Run water until
no noticeable air flow is present. Close
the zone isolation valves and proceed
with the next zone. Follow this procedure
until all zones are purged. g. Close the quick-fill water valve and purge
valve and remove the hose. Open all
isolation valves. Watch the system
pressure rise to correct cold-fill pressure.
It is recommended that you put the
pumps into manual operation to assist in
purging the circuits.
n
WARNING
Eliminate all system leaks. Continual fresh make-up water will reduce boiler life. Minerals can build up in the heat exchanger, reducing heat transfer, overheating the heat exchanger, and causing heat exchanger failure.
n
CAUTION
It is important that you purge the system of air to avoid damage to the boiler.
h. Disconnect the wires that are connected
to the THERMOSTAT terminals of the cus­tomer connection board. Apply power to the boiler. The display will show the tem­perature of the water in the boiler. Press the and {ENTER} keys simultaneously and hold for 1 second. The Display will say:
SERVICE PUMP CH PUMP ON 11:47A
and the Central Heating Pump will come on. If
you then press the key the Central Heating Pump will shut off, the display will say:
SERVICE PUMP DH PUMP ON 11:47A
and the DHW pump will come on. If the boiler
is set up as the Cascade Master and you press the key again, the DHW pump will shut off, the dis­play will say:
SERVICE PUMP SH PUMP ON 11:47A
and the system pump will come on. Using the
and keys in this manner you can toggle be­tween running each pump in the system as re­quired to help bleed out all entrapped air. Some good indicators that air is removed include the ab­sence of gurgling noises in the pipes and pump operation becoming very quiet. Pressing  and  together at any time will return the boiler control to normal operation.
i. After the system has operated for a
while, eliminate any residual air by using the manual air vents located throughout the system.
j. If purge valves are not installed in the
system, open manual air vents in system one at a time, beginning with lowest floor. Close vent when water squirts out. Repeat with remaining vents.
k. Refill to correct pressure.
Page 52

Boiler Manual
PART 9. START-UP PREPARATION (CONTINUED)
E. CHECK FOR GAS LEAKS
F. CHECK THERMOSTAT CIRCUIT(S)
1. Disconnect the two external wires connected to the boiler thermostat terminals (low voltage terminal strip).
2. Connect a voltmeter across these two incoming wires with power applied to thermostat circuits. Close each thermostat, zone valve and relay in the external circuit one at a time and check the voltmeter reading across the incoming wires.
3. There should NEVER be a voltage reading.
4. If a voltage does occur under any condition, check and correct the external wiring. (This is a common problem when using 3-wire zone valves.)
5. Once the external thermostat circuit wiring is checked and corrected if necessary, reconnect the external thermostat circuit wires to the boiler low voltage terminal strip Allow the boiler to cycle.
G. CONDENSATE REMOVAL
1. The Elite Heating Boiler
®
is a high efficiency condensing boiler, therefore, the unit has a condensate drain. Condensate fluid is nothing more than water vapor, derived from
combustion products, similar to an automobile when it is initially started. The condensation is slightly acidic (typically with pH of 3 to 5) and must be piped with the correct materials. Never pipe the condensate using steel, copper, brass or other materials that will be subject to corrosion. Plastic PVC or CPVC pipe are the only approved materials. 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 may be done by the installer or you may purchase a condensate neutralizer from Heat Transfer Products, Inc. (P/N S7350-025)
2. The Elite Heating Boiler
®
is equipped with a ¾ female socket weld fitting connection that must be piped to a local drain. It is very important that the condensate line is sloped downward away from the Elite Heating Boiler to a suitable inside drain. If the condensate outlet on the appliance is lower than the drain, you must use a condensate removal pump, available from Heat Transfer Products (#554200). This pump is equipped with two leads that can be connected to an alarm or another type of warning device to alert the user of a condensate overflow, which, if not corrected, could cause property damage.
3. If a long horizontal run is used, it may be necessary to create a vent in the horizontal run to prevent a vacuum lock in the condensate line.
4. Do not expose the condensate to freezing temperatures.
5. It is very important you support the condensation line to assure proper drainage.
H. FINAL CHECKS BEFORE STARTING BOILER
1. Read Startup Procedures within this manual for proper steps to start boiler. (See Startup Report to record steps for future reference.)
2. Verify the boiler and system are full of water and all system components are correctly set for operation.
3. Fill condensate trap with water.
4. Verify electrical connections are correct and securely attached.
n
WARNING
Before starting the boiler, and during initial operation, smell near the floor and around the boiler for gas odorant or any unusual odor. Remove boiler front door and smell interior of boiler enclosure. Do not proceed with startup if there is any indication of a gas leak. Repair any leak at once.
n
WARNING
Propane boilers only — Your propane supplier mixes an odorant with the propane to make its presence detectable. In some instances, the odorant can fade, and the gas may no longer have an odor. Before startup (and periodically thereafter), have the propane supplier verify the correct odorant level in the gas.

PART 10. 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
5. Inspect intake piping and exhaust piping for signs of deterioration from corrosion, physical damage or sagging. Verify intake piping and exhaust piping are intact and correctly installed per Venting Section, (Part 6) and local code.
I. CASCADE SYSTEM
1. If the boiler is used in a stand alone configuration, skip this section.
2. Programming The Master Boiler
1. Make sure there is no demand for heat
being supplied to the boiler
2. Apply power to the boiler
3. Enter the System Setting Program
Navigation following instructions in Part 11 of this manual.
4. Verify that Cascade Address function 15
is set to 0. This makes the master boiler address 0. NOTE: The Master Boiler MUST be addressed as 0.
5. Change Cascade Mode function 23 to 926
Boiler. This makes it the master boiler.
6. Exit the installer menu
NOTE: The temperature set point of the master must match the follower boiler set point in order for the system to operate properly.
3. Follower Boilers
NOTE: READ THE NOTES BELOW BEFORE PROGRAMMING FOLLOW­ER BOILERS:
The boiler addressed as 1 will share its alarm output with the master boiler
If one of the follower boilers has an in­direct fired water heater connected to it, the address of this boiler must be 2 or greater.
It is recommended but not necessary to address boilers in the order that they are wired.
No two boilers can have the same ad­dress
It is not required to use all consecutive address numbers. Example: In a 2 boil­er system with an indirect connected to the follower, the follower address would be 2 (address 1 is not used)
1. Make sure there is no demand for heat being supplied to the master boiler
2. Apply power to the follower boiler you are working on.
3. Enter the System Settings following instructions in part 11 of this manual
4. Set Cascade Address parameter 15 to 1 for the first follower, 2 for the second follower, etc. depending on which boiler you are programming.
5. Change “CASCADE MODE” PARAMETER to “926 BOILER”. This makes the boiler a follower boiler and enables all data to be transferred between boilers as needed for the system to function to full capability.
6. Exit the system menu
NOTE: The temperature set point of the follow­er must match the master boiler set point in order for the system to operate properly.

Cascade Control FAULT Codes Fault Code EO3
System Sensor Failure
SYS SUPPLY SENSOR PUMP OFF E03
Description:
This screen shows that there is a problem with the system sensor circuit. The circuit could be either open or shorted. Possible reasons for this error to be present are:
There is no system sensor connected to the master boiler
The system sensor is faulty
There is a short circuit in the system sensor wiring; possibly from a staple placed through the wire or damage to the wire
causing both conductors to touch.
The system sensor wiring is open due to defect or damage.
Remedy:
Disconnect the system sensor from the wiring and measure the resistance of it. Compare the meas­ured resistance to the table in this manual to see if it corresponds to the temperature of the sensor. If the resistance does not agree with the tempera­ture of the sensor, replace the sensor. If the sensor is OK, disconnect the sensor wiring from both the boiler and the sensor and check continuity using an ohmmeter. Repair or replace as necessary.
If this error is present, all boilers in the cascaded group will run and ignite simultaneously when there is a heat demand. Each boiler will modulate to maintain set point temperature on its own sup­ply sensor. The code will reset automatically when repair is complete. This code will not display if System Setting Function ERROR SYSTEM SENS is set to OFF.
Fault Code TT Temperature Blocking TT demand
TEMPER BLOCKING PUMP ON TT
Description:
This screen shows that there is a demand on the boiler from the TT circuit and that the pump is powered on and the temperature of the water at the supply sensor is too high for the boiler to ignite. This occurs because the water tempera­ture measured by the supply sensor is higher than the central heat setting – Central Diff Setting, when a demand from the TT circuit is placed on the boiler. This message will stay present until the water temperature measured by the supply sensor is less than the Central Heat Setting – Central Diff Setting.

The bottom line of the display will indicate the status of the pump.
Remedy:
Inspect the wiring from the outside sensor for damage or shorted connections and repair as nec­essary. Measure the resistance of the outdoor sen­sor and compare it to resistance chart. If not with­in the range on the chart, replace the sensor.
Fault Code E07
FLUE TEMP HIGH PUMP OFF E07
Description:
This display indicates that the flue sensor tem­perature is excessive and above 210 deg. F. When this code is displayed, the boiler will not respond to a demand for heat. When the flue temperature decreases below 194 Deg. F, the display will return to normal and allow the boil­er to respond for a demand to heat. The bottom line of the display indicates the status of the pump. The pump will remain off when this error is displayed.
Remedy:
Check the flue for obstructions or any sign of damage, especially signs of excessive heat. Repair as necessary. Run the boiler and check the flue temperature with an external ther­mometer. If the flue temperature on the ther­mometer does not agree with the flue tempera­ture displayed in the status menu, inspect the wiring to the flue temperature sensor in the boil­er and repair as necessary. If the wiring is intact, replace the flue sensor. If the flue temperature is excessive on the status menu and the test ther­mometer reads the same, check and adjust combustion controls on the boiler. If the prob­lem persists, inspect the target wall in the com­bustion chamber and replace it if cracked or damaged.
Fault Code E19
LINE VOLTAGE PUMP OFF E19
Description:
This display indicates that the line voltage fre­quency is out of range. This could happen if the boiler is being powered from a small gasoline powered generator that is not functioning cor­rectly or overloaded.
Remedy:

This code will reset automatically if it is the result of an overload and that overload con­dition is removed. The second line indicates the status of the pump. Note that while 24 volt power is low, the pump output will be on.
Remedy:
1. Check line voltage. It must be between 100­128 volts.
2. If available, connect PC and using HTP serv­ice software check the 24v supply display in the lower left corner of the screen. The num­ber displayed here must be greater than 128 and should be no greater than 250. Use this as a troubleshooting guide as you follow the steps below.
3. Remove the 10 pin Molex Connector from customer connection board. If the message clears, then the problem is with the external
sensor wiring. Examine the external sensor wiring for shorts to the ground, repairing as necessary. If the message is still present and the boiler is so equipped, disconnect the UL 353 low water cut-off to see if the message clears. Replace the faulty part. Check the low voltage wire harness in boiler for shorts to ground.
4. If a message only occurs when the burner tries to light, check the gas valve for exces­sive current draw.
5. If a message is present with the low voltage harness disconnected from the 926 control board, replace the 926 control board.
Fault Code FL
LOW WATER FLOW FL PUMP OFF
Description:
This display indicates that there is low water flow in the boiler. This code should never be displayed on the Elite Heating Boiler
®
since there is no flow switch in this product. This code will display on VWH products only. This code will reset automat­ically when the water flow is high enough for the boiler to run safely. The second line indicates the status of the pump. The pump should always be on when this code is displayed. When there is a demand, the control will start the pump, wait for the flow switch to indicate flow then try to ignite the boiler. This display occurs after the pump is energized for several seconds and the flow is still too low.
Remedy:
1. Check to see if boiler pump is functioning.
