SECTION 2.

Boiler Assembly and Placement

2A. Field Assembly

These boilers are available in two congurations; the JVH has a hot surface ignition pilot and integral draft fan, and the JVS has an electronic intermittent ignition device (I.I.D.). Look for the model designation on the rating plate, which can be found on top of the boiler in the right rear corner.

The Bradford White automatic vent dampers are standard on all JVS models. The Bradford White side wall power venters can be used on JVS models. Special instructions for their installation are included

in the vent damper and power venter package. Read

them carefully before installation.

Brute Mini JV

Vent Damper (JVS only):

1. Brute Mini JVS boilers have built-in draft diverter for natural draft operation.

2. Find the vent damper box which is located in the boiler package.

3. Install the vent damper directly to the top of the

draft diverter outlet with the damper operator

facing to the front of the boiler, and with the ow direction arrow pointing upward. Use the vent

damper wire harness provided with the boiler to connect the vent damper to the boiler. The

bracket end of the harness should be connected to

the vent damper actuator.

4. For Model JVS only: Install the metal plug

provided with the vent damper onto the damper plate hole.

5. Do not modify the automatic vent damper device. It is very important that no other vents are closed. Provide at least six inches clearance between

the automatic vent damper and combustible construction, and be sure to allow access for

servicing the damper.

Temperature/Pressure Gauge: Install the temp/

pressure gauge provided in the parts box.

2C. Flooring

JVS model boilers can only be installed on

noncombustible ooring.

JVH model boilers are designed and certied for installation on a combustible oor.

All boilers must be installed on a level oor and

must NEVER be installed on carpeting. NEVER store objects on or around the boiler.

Noncombustible ooring is dened as ooring material and surface nish not capable of being ignited and burning and with no combustible materials against the underside. Acceptable materials are those consisting entirely of a combination of steel, iron, brick, tile, concrete, slate, glass or plaster.

The JVS model boilers can be installed on a

combustible oor if a noncombustible base

assembly, available from Bradford White, is used.

See the JVS Parts List at the back of this manual for

the appropriate Noncombustible Base Kit part number.

2B. Boiler Placement

1. The boiler must be placed to provide clearances

on all sides for maintenance and inspection. There must also be minimum distances maintained from combustible surfaces. Avoid locations which can

be damaged by water or moisture.

2. A minimum of 15" (381mm) access must be

available in front of the boiler for burner tray removal. Consult local codes for clearances to hot water pipes and accessories.

3. If the boiler is to be installed in a garage, all

burners and burner ignition devices must have a minimum 18" (457mm) clearance

above the oor.

4. Boilers can be installed in a closet as long as

the minimum clearances shown in Table 2 are observed. Special attention should be paid to clearances between the front of the boiler and the closet door when it is closed (see Figure 2).

WARNING

This boiler is intended for indoor installation only.

Do not install this boiler in a location subject to

negative pressure, or improper operation will occur.

SECTION 3.

Air and Venting

3A. Combustion Air Supply

The boiler location must provide sufcient air

supply for proper combustion, and ventilation of

the surrounding area as outlined in the latest edition of U.S. ANSI standard Z223.1 or in Canada, CAN/

CGA-B149.1 or .2, and any local codes that may be applicable.

In general, these requirements specify that the boiler rooms which represent conned spaces should be provided with two permanent air supply openings; one within 12 inches (305mm) of the ceiling, the other within 12 inches (305mm) of the oor.

Page 9

NOTE: In Canada, follow Canadian Standard,

CAN/CGA-B149 or local codes.

Outside Air Supply: When combustion air is

supplied directly through an outside wall, each opening should have a minimum free area of one square inch per 4,000 BTU/h (6 sq. cm per 1.2 kW) input of the total input rating of all appliances in the

enclosed area.

Inside Air Supply: When combustion is supplied

from inside the building, each opening should have a minimum free area of one square inch per 1,000 BTU/h (6 sq. cm per 0.3 kW) input of the total input rating of all appliances in the enclosed area. These openings should never be less than 100 square inches (645 sq. cm).

Table 3. Minimum Recommended

Air Supply to Boiler Room

Exhaust Fans or Vents: Any equipment which exhausts air from the boiler room can deplete the

combustion air supply or reverse the natural draft

action of venting system. This could cause ue

products to accumulate in the boiler room. Additional

air must be supplied to compensate for such exhaust.

The information in Table 3 is not applicable in

installations where exhaust fans or blowers of any type are used. Such installations must be designed by qualied engineers. If a blower or fan is used to supply air to the boiler room, the installer should make sure it does not create drafts which could cause nuisance shutdowns. If a

blower is necessary to provide adequate combustion air to the boiler, a suitable switch or equivalent must

Vertical vents of the induced draft JVH boilers must

be installed in accordance with the code requirement

for Category 1, Fan Assisted Appliances. Follow the requirements as indicated in the latest edition of ANSI Z223.1/NFPA 54, sizing of Category I Venting System and Appendix G, or in Canada, follow the instruction

of CAN/CGA-B149 installation code. An unused lined chimney can be used as a raceway

for single wall vent pipe, (see Figure 3). Never run vent pipe through a ue that has another appliance

attached to it.

3D-1. Horizontal Venting - Category III

(JVH only)

When venting is horizontal, or cannot meet the requirements of Category I, it can develop positive

pressure and must be installed in accordance with

this section and the specic vent manufacturer’s instructions. Common venting is not allowed in Category III systems.

Materials Vent Length

In U.S.A.: UL type 304, 316 or 294-C

stainless steel or equal 26 gauge minimum. In Canada: Use "BH-Type" vent material certied to ULD-S636 Class I (more than 135°C, but not more than 245°C

ue gas temperature), made of AL29-4C stainless steel or equal.

Do not use plastic venting of any kind.

Up to a maximum

of 55' (17m) of

equivalent pipe run (including required

elbows).

The boiler vent collar must be fastened to the vent

pipe with rustproof metal screws no longer than 1/2” (13mm) and sealed with high temperature (500ºF / 260ºC) silicone sealant. For larger diameter vent pipes,

use a sealed reducer fastened directly to the boiler collar and seal all joints as indicated in Figure 7.

Allow the sealant to cure for 24 hours before operating

the boiler. The entire vent system must not exceed the size

specied in Table 4. The following criteria must be observed:

1. Attach a vertical pipe at least 12” (305mm) high

to the boiler outlet before the horizontal run if

run exceeds 5 feet (see Figure 5).

2. Support the vent run at 3’ (.9m) intervals with overhead hangers.

3D-2. Vent Connections (JVH only)

The vent system must be gas tight. All seams and joints must be sealed with silicone sealant or adhesive

tape having a minimum temperature rating of 400°F (204ºC). Use at least three corrosion resistant screws at

each slip joint, when required.

For each elbow eliminated, add 5’ (1.5m) of allowable vent.

Table 4. Horizontal Venting Conguration.

3. Pitch down the vent run, toward the vent terminal

(hood), 1/4” per foot (20mm per meter).

4. Do not locate any joint screws at the bottom of

the vent run.

3D-3. Vent Termination (JVH only)

The side wall vent terminal (hood), Bradford White

Brute Mini JV

Page 13

Part Number D2004300 (4”) or D2000401 (6”), must be used when the boiler is vented through a side wall. It provides a means of installing vent pipe through the building wall, and must be located in accordance with ANSI Z223.1/NFPA 54, or in Canada CAN/

CGA-B149 and local applicable codes, (see Figure 6 ).

Locate the vent terminal so that it cannot be

blocked by snow. Most codes requires termination of at least 12” (305mm) above grade, but the installer

must follow local codes.

3E. Common Venting System

WARNING

Operation of appliances with a blocked common

vent may lead to serious injury or death. Safety

devices must be implemented to prevent blocked

common vent operation. If safe operation of all

appliances connected to a common vent cannot

be assured, including prevention of spillage of ue

gasses into living spaces, common venting should

not be applied, and appliances should each be

vented separately.

AVERTISSEMENT

Le fonctionnement des appareils avec un

système d’évacuation bloqué peut provoquer des

blessures graves, voire la mort. Des dispositifs

de sécurité doivent être installés pour éviter le blocage des systèmes d’évacuation. Si le

fonctionnement de tous les appareils connectés

à un système d’évacuation commun ne peut

pas être assuré, y compris la prévention de la

dispersion des gaz toxiques dans les espaces

habités, on ne devrait pas installer un système

d’évacuation commun et chaque appareil devrait

être ventilé séparément.

3. Insofar as it is practical, close all building doors

and windows and all doors between the space in

which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any gas burning appliance not connected to the common venting system. Turn bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close replace dampers.

4. Place in operation the appliance being inspected. Follow the lighting instructions.

Adjust thermostat so appliance will operate continuously.

5. Test for spillage at the burner opening after ve

minutes of main burner operation.

6. After it has been determined that each appliance remaining connected to the common venting

system properly vents when tested as outlined

above, return doors, windows, exhaust fans, replace dampers and any other gas burning

appliance to their previous conditions 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 re-sizing any portion of the common venting system, the common venting system should be re-sized to approach the minimum size as determined using the appropriate tables in Appendix G in the National Fuel Gas Code, ANSI Z223.1.

SECTION 4. Gas Connections

4A Gas Supply and Piping

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 appliances remaining connected to it. At the time of removal of an existing boiler, 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 the common venting system

are not in operation.

1. Seal any unused openings in the common venting

system.

2. Visually inspect the venting system for proper

size and horizontal pitch and determine there is

no blockage or restriction, leakage, corrosion or other deciencies which could cause an unsafe

condition.

WARNING

The Brute Mini JVS and JVH boilers are

designed for use with either natural gas or LP

gas. Check the rating plate to be sure that the

boiler is designed to use the type of gas being

supplied. DO NOT ATTEMPT TO CONVERT

1. Gas piping installation must be in accordance with the latest edition of ANSI Z223.1 and all local codes. In Canada, the installation must be in

accordance with CSA-B149.1 and all local codes that apply.

2. Check the gas supply to be sure that it is the same as the gas indicated on the boiler’s plate. Brute Mini JVS and JVH boilers, as shipped from the factory, are certied to operate within the altitude range indicated on the rating plate. If a eld conversion to a different altitude range or different gas should be necessary, conversion

parts are available. Contact a Bradford White representative or the factory for the correct part numbers to order for conversions

Caution

4. A sediment trap (drip leg) must be installed ahead of the gas controls (see Figure 8). Fit the

trap with a threaded cap which can be removed

for cleaning.

5. Install a manual gas shutoff valve for service and safety. Do not use a restrictive gas cock. Flexible gas connectors, if used, must be CSA rated for the total input rating of the boiler.

6. Disconnect the boiler and its individual shutoff valve from the gas supply system during pressure testing of the system at pressures higher than 1/2 pounds per square inch (psi) (3.45 kilopascals [kPa]). If the test pressure is equal to or less than 1/2 psi (3.45 kPa), close the manual shutoff valve on the heater during the piping pressure test.

7. If the gas supply pressure is less than required, check for undersized pipe between the meter and the boiler, a restrictive tting, or an undersized gas meter. Gas supply pressures to the heater are

listed in Table 5.

NOTE: The maximum inlet gas pressure must not

exceed the specied value. The minimum value listed is for the purpose of input adjustment. Refer to Table 5.

NOTE: The boiler and all other gas appliances sharing the boiler gas supply line must be ring

at maximum capacity to properly measure the

inlet supply pressure. Low gas pressure could be an indication of an undersize gas meter and/or obstructed gas supply line.

8. The correct high re burner manifold gas pressure is stamped on the rating plate. The regulator is pre-set at the factory, and normally requires no further adjustment. For two-stage units (JVS 100-225) be sure unit is able to re at both high and low re.

9. Before operating the boiler, the complete gas

supply system and all connections must be tested

for leaks using a leak detector solution. Do not use an open ame.

Caution

Some leak test solutions (including soap and water) may cause corrosion or stress cracking. Rinse the piping with water after testing.

Attention

Certaines solultions d’essai d’étanchéité (y

compris l’eau et le savon) peuvent causer de

la corrosion ou de la ssuration. Rincez les tuyaux à l’eau apprès l’essai d’étanchéité.

Page 15

4B Special Precautions for LP Gas

LP Gas is heavier than air and can therefore more readily collect or “pool” in enclosed areas if provision

for proper ventilation is not made. Be sure to pay

special attention to proper ventilation for LP gas. Locate boilers a safe distance from LP gas cylinders and lling equipment. In the United States, consult the “National Fuel Gas Code” (NFPA 54 / ANSI Z223.1, latest edition) or in Canada, the Propane Installation Code (CSA-B149.1), any local codes and re protection authorities about specic installation

restrictions in your area.

SECTION 5. Water Connections

5A. Water Piping

Figure 10. shows ‘typical’ plumbing installations. Be sure to provide unions and isolation valves at the boiler inlet and outlet so it can be isolated for service.

Check local codes for specic plumbing requirements before beginning the installation. An ASME pressure relief valve is supplied on all JV boilers, and is pre-set at 30 PSI. The valve outlet piping must discharge to a drain. Under no circumstances should the relief valve piping be a

closed circuit.

A pressure reducing valve (automatic feed) must be

used to maintain the system at constant proper pressure

(see Figure 10). Supply properly installed purge

valves to eliminate air from each circuit. A drain valve is supplied with the boiler, and can be

found in the plastic bag shipped with each boiler. This valve is to be installed on the lower right side of the boiler and is used for draining the unit. To drain the

boiler completely, open the drain valve and remove the two drain plugs located on the lower left side of the boiler.

Be sure to include air vent devices located at the

highest point in the system to eliminate trapped air,

and an air elimination device near the outlet side of the JV boiler. Manual vent valves are recommended.

Hot water piping should be supported by suitable hangers or oor stands, NOT by the boiler. Due to expansion and contraction of copper pipe, consideration should be given to the type of hangers used. Rigid hangers could transmit noise through the system caused by the piping sliding in the hangers. It is recommended that padding be used when rigid hangers are installed. Gas piping should also be supported by suitable hangers or oor stands, not the boiler. A properly sized expansion tank must be included in

the system.

Table 7. Temperature Rise °F °C.

Page 17

5B By-pass Piping

The following information and suggestions are made on by-pass piping as it affects the temperature rise at the boiler. A boiler temperature rise must be taken on all JV boiler installations. If the temperature rise exceeds 30°F (17°C) at full rate, it is an indication that the boiler is not receiving adequate water ow. Check

the pump for any obstruction, replace the pump with a

larger size where necessary, or install a system by-pass

as indicated in Figures 10 and 11.

A full sized, 1¼" bypass with balancing valves is strongly recommended for all systems, and required when: 1) the boiler is installed without primarysecondary piping in a multiple zone system; 2) when the return water temperature can be expected to be lower than 120°F (44°C); or 3) whenever the system piping on the outlet side of the boiler may allow reduced ow through the heat exchanger, causing excessive temperature rise (see Section 5.2).

Note: Bradford White strongly recommends a primary/

secondary piping system for all installations, especially

sizes 125, 160 and 225. In this system, a circulator is dedicated to pumping the boiler only. This circulator should be sized for the boiler head loss and ow rate.

5C Adjusting the bypass:

Refer to Figure 11. Provide a means of measuring

temperature on the inlet pipe to the boiler such as

using a strap on or infrared thermometer. Starting with both balancing valves fully open, start the boiler. Adjust the balancing valve on the return to the system slowly to provide 120°F (44°C) water at the inlet to the boiler, leaving the bypass balancing valve fully

open. As the system warms up, this valve may need

to be adjusted open. In rare cases, this valve will have to be kept fully open, and the bypass balancing valve

adjusted toward closed to prevent heated bypass water

from satisfying the call for heat when the system is up

to temperature.

5D Alternate Auto-Bypass Operation

Use of the Bradford White thermostatic union, p/n 2400-030, can provide automatic bypass operation in primary - secondary piped systems (but cannot be used when primary - secondary piping is not used). The thermostatic union is installed on the outlet piping, after the bypass assembly. It can be used in place of a balancing valve. It opens fully at 140°F

(see Figure 11). Contact the factory for more information.

All precautions must be taken by the installer to insure that a maximum temperature rise through the boiler does not exceed 30°F (17°C). The temperature rise on boilers installed in multi-zone systems using zone valves must be taken when the zone of the longest length and/or the zone of the highest head loss is open.

A full size, 1¼" diameter by-pass with

balancing valve must be installed if a return water temperature below 120°F (44°C) is expected under operating conditions regardless of boiler size. This may be expected in many systems, including inoor radiant and snow melt systems.

5E Flow Requirements

All high recovery, low volume water boilers must have adequate ow for efcient operation. Pump selection is critical to this goal, and pumps should be selected to provide for system design water temperature rise. Table 7 details temperature rise and water ow (GPM)

for the Brute Mini boilers.

Damage from improper ow is not warranteed.

Failure to insure proper water ow through the heat exchanger of the boiler will void the Bradford White warranty. Flow can be veried by measuring

the difference in water temperatures between the

boiler inlet and outlet. For example: For a JV-100 installation, the inlet water temperature is 160°F (71°C), and the outlet temperature is 180°F (82°C) at Normal Input Rate from the rating plate. That means there is a 20° (11°C) temperature rise through the boiler. According to Table 7, that would indicate a ow rate of 8 GPM (0.5L/S). Temperature rise must be measured with the longest (highest head) zone calling for heat alone. Other factors to be considered before selecting a pump are pipe size, the number of ttings throughout

the system, smoothness of the interior surface of the

pipe, the quantity of water owing through the pipe, whether a glycol solution is being used, and the total length of piping in the system. Table 8 provides example pump selection criteria using Type L copper

5F Chilled Water Systems

If the boiler is installed in conjunction with refrigeration systems, it shall be installed so that the chilled medium is piped in parallel with the heating

boiler with appropriate valves to prevent the chilled

medium from entering the heating boiler. When boiler piping is connected to heating coils, which are in close proximity to refrigerated air circulation, there must be ow control valves or other automatic methods to prevent gravity circulation of the boiler water during the cooling cycle.

5G Oxygen Permeable Systems

The JV boiler must not be direct connected to a

heating system utilizing oxygen permeable tubing. Provide a water-to-water heat exchanger between

systems to prevent corrosion of ferrous metals such

as the boiler’s piping wet walls, etc. Air elimination devices are not sufcient protection, and corrosion damage is not covered under the limited warranty.

5H Anti-Freeze

Non-toxic HVAC anti-freeze may be added to the

hydronic system provided the concentration does

not exceed 50%, and the anti-freeze contains an anti

foamant and rust inhibitor. Follow the anti-freeze

manufacturer’s recommendations for yearly or

biannual replacement of system anti-freeze. Never use automotive anti-freeze in a boiler system.

Brute Mini JV

Page 19

The preferred piping configuration for JV boilers is always using primary/secondary piping.

There are some applications that are acceptable without primary/secondary piping, see below.

and connect the hot lead from the 115V power supply, and the neutral lead to the white wires.

4. Attach the leads from the wall thermostat to the terminal strip, located on the left side of the

control box.

5. Check the boiler wiring and pump for correct voltage, frequency and phase. If the pump circuit

is other than 115V, be sure there is an appropriate transformer or relay installed. The pump relay is

suitable for pumps of 1/3 HP or less (max 5A).

6. For systems with multiple zone pumps or valves

(see Figure 17).

WARNING

The boiler must be electrically grounded in

accordance with the requirements of the authority

having jurisdiction or, in the absence of such

requirements, with the latest edition of the national

Electrical Code, ANSI/NFPA 70, in the U.S. and with

the latest edition of CSA C22.1 Canadian Electrical

Code, Part 1, in Canada. Do not rely on the gas or

water piping to ground the metal parts of the boiler.

Plastic pipe or dielectric unions may isolate the boiler

electrically. Service and maintenance personnel who

work on or around the boiler may be standing on wet

oors and could be electrocuted by an ungrounded

boiler.

SECTION 7.

7A Filling the System

Page 25

It is crucial to the efcient operation of the system

that all air be removed from the circuit. For this reason, an air scoop and vent should be located close to the boiler outlet, and there should be a minimum

distance between cold water feed and system purge

valve.

1. When the system has been completely installed,

close all air vents and open the makeup water valve. Allow the circuit to ll slowly.

2. If a make-up water pump is employed, adjust the pressure to provide a minimum of 12 psi (83kPa) at the highest point in the circuit. If a pressure regulator is also installed in the line, adjust it to

the same pressure.

3. Close all valves. Purge one circuit at a time as follows:

a. Open one circuit drain valve and let water

drain out for at least 5 minutes. Be certain there are no air bubbles visible in the water

stream before closing the drain valve.

b. Repeat this procedure for each circuit.

4. Open all valves after all circuits have been purged.

5. Run the system circulating pump for a minimum of 30 minutes with the boiler shut off.

6. Open all strainers in the system, and check for

debris.

7. Recheck all air vents as described in Step 3.

8. Inspect the liquid level in the expansion tank,

with the system full of water, and under normal

operating pressure, to ensure proper water level in the expansion tank.

9. Start up boiler according to the procedures

described in Section 2 and operate the system,

including the pump, boiler, and radiation units,

for one hour.

10. Recheck the water level in the expansion tank. If it exceeds 1/2 of the volume of the tank, open the tank drain and reduce the water level.

11. Shut down the entire system, and vent all

radiation units and high points in the system.

12. Close the water makeup valve and check the strainer in the pressure reducing valve for sediment or debris. Reopen the water makeup

valve.

13. Verify system pressure with the boiler pressure

gauge before beginning regular operation.

14. Within 3 days of start-up, recheck and bleed all air vents and the expansion tank using these

instructions.

Page 26

SECTION 8.

Operating Procedures

Before placing the boiler in operation, check and reset the safety shutoff devices. Once the boiler is connected to the gas and water piping and after all the requirements in previous pages have been met, follow these procedures:

Bradford White Corp

8A. System Start-up

1. Verify that the pump system is operating properly:

a. Shut off the manual gas valve located

outside the boiler.

b. Raise the wall thermostat high enough to

call for heat.

c. The pump should come on immediately. If

it does not, test the electrical circuits.

2. Pilot and Main Burner Lighting:

a. The JV boiler does not require manual

lighting. The pilot is controlled by the automatic ignition system.

b. Different models of the JV boiler utilize

various gas valves. Although the gas valves may have different control knobs, they are

all similar in operation.

c. Understand and follow the operating

instructions that are applicable to the type

of ignition system installed on the boiler.

3. The pilot and main burners will automatically

ignite when there is a call for heat.

8B. Sequence of Operation

1. Wall thermostat will call for heat.

2. Pump relay will turn on the circulating pump.

3. If water temperature is below the limit setting,

the inducer motor relay will turn on the draft

inducer (JVH).

4. Pressure switch will sense the fan (JVH only) operation and send 24 volts to the ame rollout

switch.

5. In normal conditions, the ame rollout switch

will be in a closed position. 24 volts will be sent

to the gas valve/controller, the igniter will glow/spark and the pilot valve will open, lighting

the pilot.

6. After pilot is proven to be lit, the main gas valve will open, the main burners will ignite and

continue until either the primary control, hi-limit or wall thermostat opens.

7. When the wall thermostat is satised, the burners

will shut off. The relays will turn off the draft

inducer (JVH only) and the circulating pump.

When the room temperature falls below the wall

thermostat setting, the cycle will repeat.

8.E Operating Temperature Controls

Note: The Temperature Controllers, the Dip switch panel, and the LED panel can be found under the Control Access Panel after removing the bolts.

Two temperature controls are now standard on all

JVS and JVH boilers.

1. The primary temperature controller maintains all normal heating operations.

2. A secondary, mechanical high-limit aquastat provides safe shutdown, should the primary controller fail.

Important: If the secondary controller (See Figure 18A and Figure 18B) dial is set below 220F, it may

inhibit proper operation of the primary controller.

Prior to calling for technical support, please ensure high limit control is set for at least 220F).

Figure 18B. Secondary, mechanical high-limit

aquastat

Pump Operation. When a call for HEAT and/ or DHW is present the boiler pump will turn on. Post purge can be selected via dip switch #5, Pump Post Purge Inactive (Off) /Active 3 min. (On). In the On

position the pump will continue to run for 3 min after

the last call has been satised. When the dip switch is

Off there is no post purge of the pump, the pump turns

off immediately after the last call is removed. Bradford

White strongly recommends using a pump post purge. During WWSD and a call for HEAT is present the

pump will remain off. Pump Exercising The control exercises the boiler pump every 3 days of inactivity. While the

control is exercising the pump all LEDs will turn off and the power LED will ash for 10 seconds. Staging (where applicable – factory setting): Dip #1 is used to select the number of stages: 2-Stage (Off) / Single Stage (On). Note: Use of 2-Stage operation may reduce efciency. For 2-stage operation, the rst stage is cycled on Proportional error and the second stage is cycled based on PI according to a xed algorithm. No user

adjustment is necessary. Note: All stages are turned off when the water

outlet temperature reaches the Maximum setting that is elected via dip switch #4, Boiler Maximum 210°F (Off) / 190°F (On).

Auto Boiler Target Setpoint: Space Heating:

The boiler target temperature is automatically determined from Space Heating and DHW requirements. Space heating is based on outdoor reset. When both a Heat Call and a DHW Call are present

at the same time, the control operates to provide the

higher boiler target temperature.

Heating Curve (Outdoor Temperature Reset)

The control uses a linear heating curve to calculate a target setpoint. The following data are used to calculate the target setpoint from the outdoor

temperature.

1. The heating curve or reset ratio (RR) is set by the potentiometer with a range of 0.4 to 3.6.

2. The room temperature is xed at 70 deg F.

DHW Operation The boiler target for DHW calls is xed at 180 deg F. Note: There is no control of a DHW pump, so the boiler pump runs with the call for DHW. Limiting The boiler target is limited to a minimum and a maximum target to ensure that the water temperature does not exceed the limits.

1. Target Min - The boiler target minimum is the point at which the stages will start to turn on to

maintain a minimum water temperature. The Boiler

Minimum water temperature is 130 deg F, regardless of other calculated targets. To ensure that the water temperature is greater than the Boiler Minimum water temperature the target is increased to allow the stages

to cycle on by the Boiler Minimum water temperature,

Boiler Minimum target is set to Boiler Minimum +

differential/2.

2. Target Max - The boiler target maximum is the point at which the stages will start to turn off to maintain a maximum water temperature. The Boiler Maximum water temperature is set by setting dip switch #4: Boiler Maximum 210°F (Off) / 190°F (On).

To ensure that the water temperature is less than the

Boiler Maximum water temperature the target is decreased to allow the stages to cycle off by the Boiler Maximum water temperature, Boiler Maximum target is set to Boiler Maximum - differential/2.

Auto Differential The control automatically

adjusts differential to prevent short cycling and maximize the lifetime of components.

WWSD Operation Warm Weather Shutdown -

WWSD feature is selected via dip switch #3, WWSD Inactive (Off) / Active 70°F (On). WWSD point is xed at 70 deg F. Control exits WWSD when the outdoor temp falls to 65 F. When there is a call for HEAT and the control is in WWSD the HEAT call will be ignored. When there is a call for DHW and the control is in WWSD the DHW call will be satised. WWSD LED turns on when control detects WWSD.

Summary of Dip Switch Settings:

#1 Two Stage (Off) / Single Stage (On) (Note: Efciency may be reduced with 2-stage

operation.)

#2 (Off) / Outdoor Reset (On) (Note: Outdoor Reset

is required for residential operation) #3 WWSD Inactive (Off) / Active 70°F (On) #4 Boiler Maximum 210°F (Off) / 190°F (On) #5 Pump Post Purge Inactive (Off) / Active 3 min.

Summary of Input Sensors:

1. Outdoor sensor - monitors the outside air

temperature for outdoor reset mode

2. Boiler outlet sensor -monitors the water temperature of the boiler outlet supply

3. System Supply sensor - monitors the water temperature of the system supply

The boiler outlet sensor is required at all times. If

the boiler outlet sensor has any fault then the control

will ash an error and turns all stages off. The

system supply sensor is optional and utilizes primary

/ secondary piping. If the system supply sensor has a fault then the control ashes an error message and operates using the boiler outlet sensor (system supply = boiler outlet).

SECTION 9.

9A. Maintenance

1. Lubricate the water circulating pump per the instructions on the pump.

2. If a strainer is employed in a pressure reducing valve or the piping, clean it every six months.

3. At start-up, and periodically thereafter, the burner

and pilot ames should be observed. If the ame has the appearance of “sooting” tips, check for debris near the orices and call the service

technician.

4. Ensure proper operation of the mechanical damper, mounted in the ue collar, by observing the damper handle. Be sure the handle swings when the draft inducer starts (depending on the boiler size, swing may be as little as 30°). Remove any obstructions and clean around the pivot rod (handle) holes.

5. Inspect the venting system for obstruction, leakage or corrosion at least once a year.

6. Keep the boiler area clear and free from combustible materials, gasoline, and other ammable vapors and liquids.

7. Be sure that all combustion air and ventilation

openings are unobstructed.

8. Upon completion of the installation, inspect the external surfaces of the heat exchanger for fouling based on the following schedule:

24 hours - 7 days - 30 days - 90 days

Once every six months thereafter.

9. If the boiler is not going to be used for long periods of time in locations where freezing

occurs, it should be completely drained of all water. To accomplish this, there is a drain

valve on the right side of the boiler which can be opened. This will drain the right side of the boiler. There are two plugs located on the left

side of the heater which must be removed to drain that side. Both sides must be drained.

10. The gas and electric controls on the boiler are engineered for long life and dependable

operation, but the safety of the equipment

depends on their proper functioning. It is strongly

recommended that the basic items listed below be

inspected by a qualied service technician every

year.

a. Water temperature controls. b. Pilot safety system.

c. Automatic gas valves. d. Fan proving switch. e. Inducer/Blower assembly. f. Mechanical ue damper operation.

WARNING

The Warranty does not cover damage caused by

lack of required maintenance, lack of water ow,

or improper operating practices.

AVERTISSEMENT

La garantie ne couvre pas les dommages causés

par l'absence d'entretien, absence de débit d'eau,

ou pratiques de fonctionnement irrégulières

Fouling on the external surfaces of the heat exchanger is caused by incomplete combustion, and is a sign of venting and/or combustion air problems. The heat exchanger can be inspected by using a ashlight and placing a mirror under the burners. An alternate method is to remove the venting and top panel to inspect the exchanger from above. The vent system should be inspected at the same time. If cleaning is required:

a. Shut off all power to the boiler.

b. Remove the venting top, ue collector,

draft inducer assembly, and heat exchanger

bafes. c. Remove the burner tray. d. Use a hand-operated spray bottle lled with

water, and a wire brush to clean soot and

loose scale from the underside of the heat

exchanger. DO NOT USE COMPRESSED

AIR, HIGH PRESSURE WATER, OR A

GARDEN HOSE.

e. Clean any fallen debris from the bottom of

the unit.

f. Check to make sure the burner ports and

pilot assembly are free of debris before

returning the burner tray to its original

position.

g. Reassemble the boiler in reverse order,

making sure to replace the heat exchanger

bafes.

9B. Electrical Troubleshooting

1. Remove the control box cover on the front of the

boiler.

2. Verify that 115 volts is reaching the boiler by testing across the black wire and the white wire

on the transformer.

3. Verify 24 volts transformer output by placing the meter leads on the yellow and red wires. If

24 volts is not evident, replace the transformer.

Perform the following series of tests with one

meter lead attached to the yellow wire on the transformer.

4. Place the second lead on the “HEAT” connection

on the terminal board. Turn the wall thermostat

high enough to call for heat. If the meter fails to register 24 volts, the thermostat or its circuit may

be defective.

5. Place the second lead on the purple wire terminal

on the hi-limit switch. If no voltage across the switch, check for defective hi-limit, open circuit due to excessive water temperature, or a low temperature setting.

6. For JVH only, place the second lead on the blue wire terminal on the fan proving switch. If voltage is present, skip to step 8. If voltage isn’t

present, connections or the draft inducer/motor could be defective.

Caution

Label all wires prior to disconnection when servicing controls. Wiring errors can cause

improper and dangerous operation. Verify proper

operation after servicing.

A section of pipe (including an adjustable valve) that diverts part of the water ow from undersized piping to the boiler. Adjusted to maintain minimum ow requirement (GPM) through the boiler.

Circuit

Entire water circulation piping, beginning and ending at the boiler (Series Loop System).

Expansion Tank (Compression Tank)

Installed in the circuit to accommodate excess water produced by heat expansion.

Heat Distribution Units

Transfers heat from the water supplied by the boiler

to the area to be heated through the use of baseboard, convector, radiator, nned tube. Also known as “radiation”.

Page 35

Reverse-Return Piping

Balanced, equal ow (rst in, last out) piping. Utilized

with multiple boilers and/or radiation. Applied with

single system pumps, or primary-secondary pump.

System Purge Valve

A device used to purge air from the circuit. Should be

located as close as possible to the cold water feed, but not immediately after the cold water feed.

Temperature Controllers The primary temperature controller maintains all

normal heating operations.

A secondary, mechanical high-limit aquastat provides safe shutdown, should the primary controller fail.

Trunk

The section of piping which connects the boiler return and supply with the branch(es). Also known as a “main” or “header”. Should be same size as boiler

inlet/outlet connections.

Zone Pump

Circulators installed in branch piping that divert hot water coming from the boiler into various areas (zones) of a building.

Isolation Valve

Used to isolate the boiler from the circuit. It minimizes

the amount of water drained from the system.

Primary-Secondary Piping

Two or more interconnecting circulating loops, each with its own pump. Primary =System Circuit; Secondary=Boiler Circuit.

Zone Valve

Diverts hot water from the boiler into various areas (zones) of a building.
