A.
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.
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.
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).

Figure 1: Horizontal Air Delivery
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.
5
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.
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

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.
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 explosion-
proof 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.

A.
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.

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 low-
pressure 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.
• 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
Typical BH Unit Arrangement
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.

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
A
= Btu
S
x Heating Capacity Factor
c. To select a heater capacity based on standard
conditions to meet a heating capacity at non-
standard (actual) conditions:
Btu
S
= Btu
A
/ 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:
Btu
A
= Btu
S
x Btu Correction Factor
GPM
A
= GPM
S
x GPM Correction Factor
WPD
A
= WPD
S
x WPD Correction Factor
c. To select a heater capacity based on standard
conditions to meet a heating capacity at non-
standard (actual) conditions:
Btu
S
= Btu
A
/ Btu Correction Factor
d. Other useful formulas:
FAT
A
= EAT
A
+ [(460 + EAT
A
) x (Btu
A
) / (576 x
Cfm
S
)] For BH units only
FAT
A
= EAT
A
+ [(460 + EAT
A
) / (576 x Cfm
S
/
Btu
A
)-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
AG
= Btu
S
(or Btu
A
) x Glycol Correction
Factor
c. To select a heater capacity based on standard
conditions to meet a heating capacity with glycol
solution:
Btu
S
(or Btu
A
) = Btu
AG
/ Glycol Correction
Factor
4. Refer to Table 14:
To determine how water temperatures other than
200°F affect mounting height of unit.
Max. Mounting Height
A
= Max. Mounting
Height
S
x Correction Factor
5. Terminology:
a. Btu
A
= Capacity at non-standard (actual)
conditions
b. Btu
AG
= Capacity with Glycol solution
c. Btu
S
= Capacity at standard conditions (200°F
entering air temperature, 60°F entering air
temperature) from Tables 9 and 10
d. Cfm
S
= Unit airfl ow as found in Tables 9 and 10
e. EAT
A
= Entering air temperature at actual
conditions
f. FAT
A
= Final air temperature at actual conditions
g. GPM
A
= Water fl ow rate at actual conditions in
GPM
h. GPM
S
= Flow rate at standard conditions (200°F
entering water temperature, 60°F entering air
temperature) from Tables 9 and 10
i. Max. Mounting Height
A
= Maximum mounting
height at actual conditions
j. Max. Mounting Height
S
= Maximum mounting
height at standard conditions
k. WPD
A
= Water pressure drop at non-standard
(actual) conditions
l. WPD
S
= Water pressure drop at standard
conditions (200°F entering water temperature,
60°F entering air temperature) from Tables 9 and
10
