II. GENERAL INFORMATION

A. INSTALLATION LIMITATIONS

Installation and service instructions in this manual are

applicable to the steam/hot water unit heaters which should be installed in their proper applications for their most effective function as overhead heating units. The copper coils are warranted for operation at steam or hot water pressures up to 150 psig, and/or temperatures up to 375°F. Canadian Standards Association (CSA) requirements state that explosion-proof units may not be used with a ﬂ uid temperature in excess of 329°F and still maintain their explosion-proof rating, for national electric code ignition temperature rating T3B for grain dust.

B. INSPECTION ON ARRIVAL

1. Inspect unit upon arrival. In case of damage, report immediately to transportation company and your local Burnham Hydronics Representative.

GNINRAW

DRAUGNAFTELTUOEVOMERTONOD

.STINUVBLEDOMMORF

2. Check rating plate on unit and motor to verify that power input and motor speciﬁ cation meet available electric power at point of installation.

3. Inspect unit received for conformance with description of product ordered (including speciﬁ cations where applicable).

III. INSTALLATION

SPECIAL PRECAUTIONS

1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage. All units must be wired strictly in accordance with wiring diagram furnished with unit.

2. Units should not be installed in atmospheres where corrosive fumes or sprays are present.

3. Units must not be installed in potentially explosive or ﬂ ammable atmospheres.

4. Be sure no obstructions block air intake or air discharge of unit heater.

5. Do not install unit above recommended maximum mounting heights (see Table 1) or below the minimum height of eight feet.

B. UNIT SUSPENSION

Horizontal Delivery Units, Model BH Series

All horizontal delivery units have two tapped holes

(3/8”-16) in the top for unit suspension. Piping support hangers or clamps are recommended and should be placed as close to the unit heater as possible. For other models, independent suspension can be made with threaded rods, pipes, or ceiling hanger brackets.

Figure 1: Horizontal Air Delivery

Vertical Delivery Units, Model BV Series

Models BV-42 through BV-161 have 4 tapped holes

(1/2”-13) on the top surface for unit suspension. Suspension can be made with threaded rods, pipes, or ceiling hanger brackets. Models BV-193 through BV-610 have angle-iron frame mounting brackets for heavy-duty installation with applicable hardware.

No Deﬂ ector

accessories. Locate horizontal delivery unit heaters so air streams of individual units wipe the exposed walls of the building with either parallel or angular ﬂ ow without blowing directly against the walls. Heaters should be spaced so the air stream from one supports the air stream from another heater. Locate vertical delivery unit heaters in the center area of the space to be heated, using horizontal delivery unit heaters along the walls where heat loss is usually greatest.

D. PIPING INSTALLATION

Horizontal and Vertical Unit Heaters

Note: Only make piping connections using two (2)

pipe wrenches. One wrench is used as a “back-up” while the other wrench is used for applying force necessary to tighten the ﬁ tting.

C. UNIT HEATER MOUNTING HEIGHT

Do not install unit above recommended maximum

mounting heights or below the minimum height of eight feet. The height at which unit heaters are installed is critical. Maximum mounting heights for all units are listed in Table 1. Maximum mounting heights for Model BV is given for units with or without air diffusion

The illustrations, on page 6, suggest four (4) different

piping conﬁ gurations. Refer to the ASHRAE Guide & Specialty Manufacturer for selection of ﬁ lter, piping traps and other specialty sizing. Piping is typical for unit heaters.

E. WIRING INSTRUCTIONS

1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage. All units must be wired strictly in accordance with wiring diagram (Figure 3).

2. All wiring must be done in accordance with the National Electric Code and applicable local codes. In Canada, wiring must conform to the Canadian Electric Code. It is recommended that all wiring be adequately grounded.

3. Electric wiring must be sized to carry the full load amp draw of the motor, starter, and any controls that are used with the unit heater. Overcurrent protectors should be sized based on motor current rating shown on the unit serial plate, and applicable national electric code procedures.

4. All units should be installed with an electrical junction box. Junction boxes are either integral to the motor or to be attached to the unit casing. Units with explosion-proof motors have an explosionproof junction box attached to the motor. Any damage to or failure of Burnham Hydronics heater units caused by incorrect wiring of the units is not covered by Burnham Hydronics standard warranty.

IV. OPERATION

A. PRIOR TO OPERATION

1. Check all electrical connections to assure they are secure.

2. Check rigidity of unit mounting. Tighten all fasteners, if necessary.

3. Inspect piping, strainers, traps, ﬁ ttings, etc.

B. INITIAL START-UP

1. Set thermostat to lowest position.

2. Turn on power supply to unit.

3. Open return gate valve, and then open supply gate valve to unit.

4. Raise thermostat setting to desired position.

5. Adjust louvers (if provided) for desired heat distribution.

6. To insure proper sequence of operation, cycle unit on and off a few times by raising and lowering thermostat setting.

7. Check for proper rotation of fan. All fans must rotate in a counterclockwise direction when viewed from the back (BH) of the unit heater.

V. MAINTENANCE

INSPECT REGULARLY

Under average conditions, it is recommended that

unit heaters be inspected before every heating season — more often in locations where air is contaminated with corrosive fumes, dust, soot or oil spray. Check for dirty, clogged coils, excessive vibration and loose connections. Inspect piping, strainers, traps, ﬁ ttings, etc.

B. MOTORS

1. Cleaning Remove grease and dirt on motor during each

inspection or lubrication. Open frame motors should be blown clean every heating season, or whenever coils are cleaned, whichever is sooner.

2. Lubrication Lubricate motor according to manufacturer’s

instructions located on the motor. When no motor oiling instructions are on the motor, oil the motor every two thousand hours of operation with SAE20 motor oil for units in normal applications. Adjust oiling according to usage and atmosphere. Some motors do not have oil ﬁ ttings. These motors are lubricated for long life and do not require further lubrication.

3. Overload Protection A change in line voltage higher or lower than motor

nameplate rating may cause overheating and serious motor damage. Check plant voltage conditions. A separate manual starter with thermal overload protection device is recommended for those units that do not have motors with built in overload protection.

C. CASINGS

1. Cleaning Periodic cleaning of casings is recommended to

remove dirt, grease and corrosive substances that may injure ﬁ nish. Rusted or corroded spots should be cleaned and repainted.

2. General Inspection Tighten fan guard and motor bracket. Check fan for

proper clearance, free rotation and ﬁ rm connection to shaft. When servicing is complete, tag unit to indicate date of inspection, lubrication and cleaning.

D. COILS

1. Cleaning Clean coil at least once a year, more often under

unfavorable conditions. Unless coil is kept reasonably free of dirt, lint and grease, its original heating capacity will be reduced — possibly to a serious degree, and motor damage may result.

Two commonly used cleaning methods are:

a. Loosen dirt by brushing ﬁ ns on side where air

enters coil and then turn on fan to blow dirt from unit.

b. Use high-pressure air hose to loosen dirt by

blowing from side where air leaves coil (side adjacent to louvers on blow-through units (BH); side adjacent to fan on draw-through units (BV)). For thorough cleaning of coil, remove motor and fan and spray a mild alkaline cleaning solution over the coil. After a few minutes, follow by a hot water rinse. (A steam gun can be used for spraying cleaning solution and hot water.) Coils subjected to corrosive fumes should be checked and cleaned frequently.

2. Internal Corrosion Safeguards Provide controlled water treatment -- don’t use

excess of boiler compounds. Contact your boiler compound supplier for proper usage or the services of a water treatment laboratory. Periodic internal ﬂ ushing of the coils is recommended in areas where water supply is suspected of causing scale. Use an alkaline-chelant solution and introduce it at the main pump of the hydronic system. Flush thoroughly.

,egamaderevesotdaelyam,detibihni

.egakaeldnanoisorrocgnidulcni

De-aerate boiler feed-water (particularly if large

amount of new water is used). Insure rapid continuous and adequate condensate drainage by properly sized and installed traps and piping. Check traps for sticking. Clean strainers ahead of traps. (When traps don’t work, condensate accumulates in unit heater coil; water hammer results.) Adequately vent each unit. Use lowpressure steam when possible.

VI. APPLICATION GUIDELINES

A. GENERAL GUIDELINES

1. The ﬁ rst step in the design of a job is typically to determine the heat loss. Refer to ASHRAE and others for publications on the basic methodology used in calculating the building or area’s heat loss. Special attention should be paid to the building type (architecturally) and application placement (area use) in this procedure.

2. The second step is to decide the necessary engineering data for design conditions such as CFM, ﬁ nal air temperature, quantity and location of units, based on the speciﬁ c Burnham Hydronics Unit Heater model selected.

3. Burnham Hydronics steam/hot water unit heaters’ versatility offers a wide selection of outputs and airﬂ ow allowing almost unlimited ﬂ exibility in job design.

4. Keep the following guidelines in mind when designing any job using steam/hot water unit heaters:

• Always direct airﬂ ow to regions of greatest heat

loss.

considering the nuisance of a loud unit. All units were designed to minimize sound created by airﬂ ow and motor operation by careful component selection and inlet geometry. Sound Classiﬁ cation Table 2 shows typical rooms and their corresponding sound class rating.

Typical BH Unit Arrangement

• Use louvers for adjustment of throw length and

complete directional control of airﬂ ow.

• Mount units at the lowest practical and allowable

level.

• Select lower CFM models for lower installation

heights and heavily occupied areas. Select higher CFM models for areas where higher installation is required.

• More, smaller units will provide better heat

distribution than fewer larger units.

• Watch ﬁ nal air temperatures on units mounted at

lower levels or in heavily occupied areas to ensure that air is warm enough to avoid drafts being felt.

• Sound classiﬁ cations: Burnham Hydronics Unit

Heaters provide exceptional heat output while

= BtuS x Heating Capacity Factor

c. To select a heater capacity based on standard

conditions to meet a heating capacity at nonstandard (actual) conditions:

BtuS = BtuA / Heating Capacity Factor

2. Refer to Table 6: a. To determine the air temperature rise of a unit

heater at a steam pressure and/or entering air temperature other than standard conditions of 2 lb. Steam, 60°F entering air temperature.

b. To ﬁ nd actual air temperature rise of unit

heater when operating at non-standard (actual) conditions:

ATRA = (FATS - EATS) x Air Temperature Rise

Factor

c. To ﬁ nd actual ﬁ nal air temperature of unit

heater when operating at non-standard (actual) conditions:

FATA = EATA + ATR

3. Refer to Table 7:

To determine how non-standard steam pressures

(other than 2 lb.) affect mounting height.

Max. Mounting HeightA = Max. Mounting

HeightS x Correction Factor

4. Refer to Table 8: To determine the rate of condensate production at

steam pressures other than 2 lb.

Condensate Rate = BtuA / Latent Heat of Steam

5. Terminology: a. ATRA = Air temperature rise at non-standard

(actual) conditions b. BtuA = Capacity at actual operating conditions c. BtuS = Capacity at standard conditions (2 lb.

Steam, 60°F entering air temperature) from

Tables 3 and 4. d. EATA = Entering air temperature at non-standard

actual) conditions e. EATS = Entering air temperature at standard

conditions (60°F) f. FATA = Final air temperature at non-standard

(actual) conditions g. FATS = Final air temperature at standard

conditions from Tables 3 and 4. h. Max. Mounting HeightA = Maximum mounting

height at actual conditions i. Max. Mounting HeightS = Maximum mounting

height at standard conditions

HOT WATER CALCULATION FORMULAS

1. Refer to Table 11: a. To determine the heating capacity (Btu/hr) of a

unit heater at a water temperature and/or entering air temperature other than standard conditions of 200°F entering water temperature, 60°F entering air temperature.

b. To ﬁ nd actual unit heater capacity when

operating at non-standard (actual) conditions:

Btu

= BtuS x Heating Capacity Factor

c. To select a heater capacity based on standard

conditions to meet a heating capacity at nonstandard (actual) conditions:

BtuS = BtuA / Heating Capacity Factor

2. Refer to Table 12: a. To determine how water temperature drop affects

heat capacity in Btu, water ﬂ ow rate is in GPM and pressure drop in feet of water. These factors should be applied to the values at actual entering water and air temperature conditions.

b. To ﬁ nd actual unit heater capacity or ﬂ ow rate

or pressure drop when operating at non-standard (actual) conditions:

BtuA = BtuS x Btu Correction Factor

GPMA = GPMS x GPM Correction Factor WPDA = WPDS x WPD Correction Factor

c. To select a heater capacity based on standard

conditions to meet a heating capacity at nonstandard (actual) conditions:

BtuS = BtuA / Btu Correction Factor d. Other useful formulas: FATA = EATA + [(460 + EATA) x (BtuA) / (576 x

CfmS)] For BH units only

FATA = EATA + [(460 + EATA) / (576 x CfmS /

BtuA)-1)] For BV Units only

3. Refer to Table 13: a. To determine how glycol solutions affect heater

capacity. These factors should be applied to the heater capacity at actual entering water and air temperature conditions.

b. To ﬁ nd actual unit heater capacity when operated

with glycol solution:

Btu

= BtuS (or BtuA) x Glycol Correction

Factor

c. To select a heater capacity based on standard

conditions to meet a heating capacity with glycol solution:

Btu

(or BtuA) = BtuAG / Glycol Correction

Factor

4. Refer to Table 14: To determine how water temperatures other than

200°F affect mounting height of unit.

Max. Mounting HeightA = Max. Mounting

HeightS x Correction Factor

5. Terminology: a. BtuA = Capacity at non-standard (actual)

conditions b. BtuAG = Capacity with Glycol solution c. BtuS = Capacity at standard conditions (200°F

entering air temperature, 60°F entering air

temperature) from Tables 9 and 10 d. CfmS = Unit airﬂ ow as found in Tables 9 and 10 e. EATA = Entering air temperature at actual

conditions f. FATA = Final air temperature at actual conditions g. GPMA = Water ﬂ ow rate at actual conditions in

GPM h. GPMS = Flow rate at standard conditions (200°F

entering water temperature, 60°F entering air

temperature) from Tables 9 and 10 i. Max. Mounting HeightA = Maximum mounting

height at actual conditions j. Max. Mounting HeightS = Maximum mounting

height at standard conditions k. WPDA = Water pressure drop at non-standard

(actual) conditions l. WPDS = Water pressure drop at standard

conditions (200°F entering water temperature,

60°F entering air temperature) from Tables 9 and

B. CONTROL SEQUENCES

The following control sequence descriptions are

commonplace for steam/hot water horizontal and vertical air delivery unit heaters.

1. Intermittent Fan Operation - Intermittent Hot/Cold Coil

a. When a thermostat calls for heat, the motor is

energized. At the same time, a valve is opened allowing the heating ﬂ uid to enter the unit heater.

b. Placing an aquastat to the supply or return

piping will prevent motor operation until coil is properly heated to avoid the delivery of cold air.

c. After thermostat is satisﬁ ed, motor is de-

energized.

2. Intermittent Fan Operation - Hot Coil a. When a thermostat calls for heat, the motor is

energized.

b. The heating ﬂ uid is continuously supplied to the

unit heater, even with the motor off.

c. After thermostat is satisﬁ ed, motor is de-

energized.

3. Continuous Fan Operation - Intermittent Hot/Cold Coil

a. When a thermostat calls for heat, a valve opens,

allowing the heating ﬂ uid to enter the unit heater. b. After the thermostat is satisﬁ ed, the valve closes. c. The fan runs continuously.

U.S. Boiler Company, Inc. warrants to the original owner at the original installation site that products manufactured by U.S. Boiler Company, Inc. comply, at the time of manufacture, with recognized Hydronics industry regulatory agency standards and requirements then in effect and will be free from defects in materials and workmanship for a period of one year after the date of installation.

The remedy for breach of this warra nty is expressly limited to the repair or replacement of any part found to be defective under conditions of normal use and does not extend to liability for incidental, special or consequential damages or losses such as loss of the use of the products, inconvenience, loss of time or labor expense involved in repairing or replacing alleged defective product. U.S. Boiler Company, Inc. shall have no responsibility for the performance of any product sold by it under conditions varying materially from those under which such product is usually tested under existing industry standards, nor for any damage to the product from abrasion, erosion, corrosion, deterioration or the like due to abnormal temperatures or the influence of foreign matter or energy, nor for the design or operation of any system of which any such product may be made a part or for the suitability of any such product for any particular application.

For products or parts not manufactured by U.S. Boiler Company, Inc., the warranty obligation of U.S. Boiler Company, Inc. shall, in all respects, conform and be limited to the warranty actually extended to U.S. Boiler Company, Inc. by its vendors.

Warranty service can be obtained by contacting the original installer of the product and providing him with a detailed description of any apparent defect. If this procedure fails to result in satisfactory warranty service, the owner should notify U.S. Boiler Company, Inc., P.O. Box 3079, Lancaster, PA 17604. Transportation to a factory or other designated facility for repairs of any products or items alleged defective shall, in all events, be the responsibility and at the cost of the owner.

Notwithstanding any of the above provision, (1) failures resulting from misuse, improper installation or lack of maintenance are not covered by this warranty, and (2) U.S. Boiler Company, Inc.’s liability under this warranty

shall not exceed the selling price of the product found to be defective.

Equipment furnished by the Buyer, either mounted or unmounted, and when contracted for by the Buyer to be

installed or handled is not covered by this warranty. U.S. Boiler Company, Inc. does not assume any responsibility in connection with such equipment, operation, warranty, performance, or any other liability connected thereto.

Then foregoing provisions of this WARRANTY shall be effective to the maximum extent permitted by applicable law, and, to the extent that any such provision would otherwise have an unconscionable result or would otherwise be inconsistent with applicable law, such provision shall be limited in effect to the minimum extent necessary to avoid such unconscionable result or inconsistency with applicable law.

Any implied warranties, including implied warranties of merchantability and fitness for a particular purpose shall, to the extent permitted by applicable law, be limited in duration to a period of one year after the date of installation. To the extent permitted by applicable law, the remedies for breach of any such implied warranty shall be limited to the remedies set forth above with respect to a breach of the express limited warranty provided. With respect to the limitations on implied warranties set forth above, U.S. Boiler Company, Inc. hereby notifies each person to whom such warranty is made as follows: Some states do not allow limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages, so the above limitations, or exclusions may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
