WARNING: Improper installation, adjustment, alteration,
service or maintenance can cause serious injury or
property damage. Refer to this manual. For assistance
or additional information, consult a qualified installer or
service agency.
WARNING: If the information in these instructions is not
followed exactly, fire or explosion may result and can
cause property damage, personal injury or death.
DO NOT INSTALL THE WATER HEATER ON COMBUSTIBLE FLOORING. Install in accordance with all local
codes. In the absence of local codes, refer to NFPA 31
or ANSI Z21.10.1, or contact Bock Water Heaters with
questions concerning proper flooring materials.
which could occasionally exceed 120oF. The variation in
outcoming temperature could be based on factors including but not limited to usage patterns and type of
installation. Test your water at the tap nearest to the water heater.
WARNING: Hotter water increases the risk of scald injury. Before changing the temperature setting, read the
instruction manual. Temperatures at which injury occurs
vary with the individual’s age and length of exposure.
The slower reaction times of children, elderly and physically or mentally impaired persons increases the
scalding hazard to them. It is recommended lower water temperatures be used where these situations exist.
To lower water temperature use point-of-use temperature limiting devices.
WARNING: Flammable vapors may be drawn to this
water heater from other areas of the structure by air currents. Do not store or use any flammable liquids in
the vicinity of this heater.
WARNING: Water heater blankets may restrict air flow
to the heater and cause fire, asphyxiation, personal injury or death.
Minimum clearance to combustible construction is:
SIDES 6"; BACK 6"; FRONT 24". The installation of this
water heater must conform with local codes and ordinances. In the absence of local codes, the installation
must comply with the National Fire Protection Association (NFPA 31) Code.
WARNING: The recommended temperature for normal
residential use is 120oF. The dial on the aquastat does
not always reflect the outcoming water temperature,
WARNING: Hydrogen gas can be produced in a hot
water system that has not been used for an extended
period–generally, two weeks or longer. To prevent possible injury under this situation, we recommend that a
hot water faucet be wide open for several minutes
before you use ANY electrical appliance that is connected to the hot water system. If hydrogen is present, an
unusual sound – such as air escaping – will come from
the open faucet as the hot water begins to flow.
Hydrogen gas is extremely flammable – there must
be no open flame near this open faucet.

COMBUSTION &
VENTILATION AIR
NOTE: All ducts
must have the same
cross sectional area
as the free area of
each opening to
which they connect.
The minimum side
dimension of a rectangular duct must
be no smaller than
three (3) inches.
Care must be taken to insure an adequate air supply for the water heater.
A. Install equipment only where the water heater will have satisfactory combustion, proper venting,
and the maintenance of temperature at safe limits all around the unit under normal operating conditions. Free circulation of air around the water heater is essential. If the air supply is inadequate,
introduce outside air. Any temperature above 90°F around the heater indicates a need for additional air (see NFPA 31 for air requirements).
B. In addition to air needed for combustion, air may be required for draft control; cooling off; controlling
dew point; heating; drying; oxidation or dilution; safety exhaust; odor control; and compressors.
C. Make sure air around the water heater is adequate for personnel comfort and working conditions.
D. Check for proper draft. Place a draft gauge in the chimney above the draft diverter. Drafts should
be at least -0.02" W. C. and less than -0.05” W.C. while the water heater is in operation.
Unconfined space: No additional combustion and ventilation air is required if the volume of the
space is greater than 50 cubic feet per 1,000 BTUH of the combined total input of all equipment installed in that space. Rooms leading directly to the space through openings which cannot be closed
are considered part of the unconfined space.
Confined space: When the unit will be installed in a space with a volume of less than 50 cubic feet
per 1,000 BTUH, the space must be vented at the floor for combustion air and at the ceiling for ventilation. This air can be supplied from either inside or outside of the building as conditions allow (refer
to NFPA 31 or local codes).
A. Inside air supply: Provide two permanent openings; one within 12" of the top of the enclosure and
one within 12" of the bottom, leading directly to room(s) of sufficient volume so that the combined
volume of all the space meets the criteria for unconfined space. Each opening requires a minimum free area of one (1) square inch (two square inches total) per 1,000 BTUH of the combined
total input of all equipment installed in the enclosure, but not less than 100 square inches.
B. Outside air supply: Provide two permanent openings; one within 12" of the top of the enclosure
and one within 12" of the bottom. These openings must lead directly to crawl and attic spaces
leading directly to the outside of the building.
1. Leading directly to outside or through vertical ducts: Each opening (top and bottom)
requires a minimum free area of one (1) square inch (two square inches total) per 4,000 BTUH
of the combined total input of all equipment installed in the enclosure.
Caution: Operation
of exhaust fans, ventilating systems,
power burners, induced draft systems,
clothes dryers, or
fireplaces may create conditions that
require special
attention to avoid
unsatisfactory operation of installed
equipment.
T&P RELIEF VALVE
ATTACH BURNER
& OIL LINES
–3–
2. Leading to the outside through horizontal ducts: Each opening (top and bottom) requires
a minimum free area of one (1) square inch (two square inches total) per 2,000 BTUH of the
combined total input of all equipment installed in the enclosure.
Louvers and grilles: In calculating the “free” area in Equipment Located in Confined Spaces,
consider the blocking effects of louvers, grilles, or screens protecting openings. The screens cannot
be smaller than one (1) inch of mesh. If the “free” area of a louver or grille is known, it should be
used in calculating the size opening required to provide the “free” area specified. If the design and
“free” area is not known, assume wood louvers have 20% to 25% “free” area, and metal louvers and
grilles 60% to 75%. Fix louvers and grilles in the open position or interlock with the equipment so
they are opening automatically during equipment operation.
WATER PIPING: Models 72E, 73E, 190E, 241E and 361E have polysulfone dip tubes. When using
sweat fittings, do not apply heat to the nipples. Pipe hot and cold lines with a union and valve on
each line.
If backflow preventers and pressure regulators are installed or if the heater is installed in a closed
system, allow for water expansion by installing either a thermal expansion valve or an expansion
tank in the system. Contact the local water supplier or plumbing inspector to correct the situation.
The Bock factory has installed the properly rated temperature and pressure (T&P) relief valve.
To prevent water damage when relief occurs, install a discharge line from the relief valve outlet to a
place for water disposal. Do not install reducing coupling or other restriction in the discharge line.
Arrange the line to allow complete drainage of both the relief valve and the discharge line. If the T&P
relief valve discharges periodically, service to the water system is required.
Do not place the shut-off valve between the relief valve and the water heater.
Check handholes for tightness.
1. The operating thermostat and high limit are packed with the burner. Mount the burner with bolts
provided. Burners are shipped with all settings at the approximate start point. Check inside the
combustion chamber to verify that the burner tube is not obstructed or protruding into the chamber. Swing back the hinged transformer and rotate the blower wheel by hand a few turns to loosen
the pump seal.
Install a water softener if the heater is
being used in a hard
water area (water
hardness of more
than seven grains).
FIGURE 1
2. Bock recommends a two-pipe (suction and return) system for these heaters. Use 1/2" O.D. soft copper tubing (5/8” O.D. soft copper on Sun Tec H pumps) and install a bypass plug on two-pipe system.
(See instructions packed with pump.) Note: Do not install a bypass plug if using a gravity (one-pipe)
system. (See Figure 1.) For multiple heater installations, run a separate suction and return line for
each heater. (See Figure 2.) If the combined lift and horizontal run exceeds 100’, install a booster
pump as close to the supply tank as possible.
Booster pumps may be obtained from Sun Tec Hydraulics, Rockford, Ill.
GRAVITY SYSTEM
FIGURE 2
3. Return lines must be the same diameter as suction lines and extend close to the
bottom of storage tank but stop slightly above suction lines. Use a minimum of fittings and make bends in tubing with as large a radius as possible. Always use
flared fittings, not compression fittings. If pipe is used instead of tubing, do not connect the burner to the pipe – use copper tubing and form a coil before attaching tubing to burner.
4. When installing an oil water heater with an existing oil tank and lines, check existing line sizes and compare to instructions shipped with the pump to see if they are
adequate. Do not use existing lines if they are smaller than 1/2" O.D. tube on
Models 361E and 541E. Proceed as follows:
A. If existing oil heater has a one-pipe system, tee into the system to furnish oil to the
heater.
B. If the existing oil heater has a two-pipe system, check whether the return line extends
to the bottom of the tank. It may be preferable to change the existing oil heater to a onepipe system and change the return line to the suction line for the heater.
C. If (B) is not applicable, tee into the existing suction line and the existing return line to
supply oil to the heater. Both suction and return lines must extend to the bottom of the
tank, but if the tubing is too small and a two-stage pump is on the existing oil appliance,
the water heater pump may be starved for oil.
D. If return lines do not extend to the bottom of the tank, use check valves on each suction line as close to each burner as possible to prevent air from being drawn through the
return line.
E. Before teeing into an existing oil line, check the vacuum gauge in the 1/4" inlet port or the vent
opening. A single-stage pump should not exceed 12" hg vacuum and a two-stage pump should not
exceed 17" hg vacuum on two-pipe systems.
If the heater performs poorly, recheck the vacuum reading – a high reading will indicate too much
resistance. This could be caused by a clogged filter, a restricted shutoff valve, kinked tubing, an obstruction in the oil line, excessive lift or too long a run.

–4–
F. If none of the above installations are suitable, Bock recommends an oil booster pump located as
close to the oil supply as possible. Use the existing supply and return lines for the booster pump.
Change the existing unit to a one-pipe system and tee off the one pipe to supply oil to the water heater.
Using “L” or “A” type venting, connect the heater to the chimney. Do not reduce the smoke pipe diameter; use the same size smoke pipe as the heater flue pipe. Run a separate connector from the heater
to the chimney where possible. If the heater must be joined to another oil appliance breaching before
going into the chimney, enlarge the existing breaching to accommodate the extra volume of gases from
the heater. The entrance into the breaching should be at a 45O angle.
Wiring must be done in accordance with the National Electrical Code and local ordinances. Burners are
supplied with an operating thermostat (Honeywell L4103A or Carlin EZ-Temp 90000B on 72E,
Honeywell L4006A or Carlin EZ-Temp 90000C or Carlin EZ-Temp 90300B on the 73E through 361E,
and Honeywell L8100C or Carlin EZ-Temp 90300B on 190E and 541E). Models 73E through 541E
equipped with Honeywell controls are also supplied with a separate L40801B high limit (see wiring diagrams). The operating thermostat should be set at 120OF for normal domestic hot water use; higher
temperatures increase the risk of scalding. Do not set higher than 180OF. The differential control wheel
on the L4006 control (73E-361E) should be set to 15OF. The high limit control (L4080B used on 73E541E) should be set 20OF or higher above the operating thermostat setting. The maximum setting is 200OF.
Fill the heater with water, opening a hot water faucet to allow trapped air to escape. Check handholes for
tightness. Check the fuel supply and all fuel lines for tightness. Rotate the blower wheel to loosen the
pump shaft seal. Bleed air from the oil line by opening the bleed valve on the fuel pump. Attach a small
plastic tube to the bleed valve fitting on pump and run to a gallon container. Turn on the electricity and set
the thermostat so the burner motor runs. The heater will not ignite when the bleed valve is open. Bleed
the line until the oil is completely clear (not milky or opaque), transparent and free of air bubbles and froth.
Shut the bleed valve and the burner will ignite. Remove the plastic tube. To keep the burner control from
locking out while bleeding, attach a jumper between the flame detector terminals after starting the burner (remove the jumper when done). Double-check control settings as described previously.
SET DRAFT AND
ADJUST BURNER
COMBUSTION (see
burner instructions)
1. Start the burner and adjust draft to the -.02 in H2O to -.05 in H2O.
2. Verify that the pump pressure matches the values in the chart.
3. Check the smoke and adjust the air to give #1 smoke.
4. Readjust to give a trace or zero smoke.
5. Check that the CO2/O2 level is at 11% or higher. Note: Do not attempt to adjust the burner without
instruments.
6. Open the air adjustment to lower the CO2 by .5% or 1% to allow for draft and fuel variations (refer
to the burner manufacturer’s recommendations).
SERVICE:
The thermostat has been adjusted to 120°F at the factory. Wait until thermostat has shut off fuel to the
main burner; wait 30 seconds following shut off of fuel, then set thermostat to the highest temperature.
The main burner should re-light. Set thermostat to the lowest temperature; the main burner should go
out. The thermostat should be adjusted in accordance with the local codes or to the minimum setting
that will meet the hot water needs of the consumer. Bock recommends 120°F temperature settings for
residential applications for safety as well as energy efficiency.
1. Check the fuel supply, electrical wiring and fuses. Make sure the temperature control is set for heat.
2. If the motor runs but there is no flame, remove the electrode assembly, clean and readjust. Check
the electrode porcelain for cracks and replace if necessary. Check the transformer to see if it is producing a strong spark. (Use extreme caution – the transformer has a 10,000 volt output.) Check that
the coupling between the motor and pump shaft is not slipping. Check the set screw on the blower
wheel for tightness. Clean or replace the nozzle if necessary, always using the correct size and
spray angle provided by the manufacturer.
3. Bleed the pump to make sure the oil is clear and free of air bubbles. If the oil is milky or frothy, check
the line for air leaks at fittings. Check the oil filter gaskets and make sure the filter cartridge is clean.
4. If the burner motor does not run, check the motor thermal overload button (red) and reset. If the
burner motor does not run after pushing the red button on the back of the motor, turn the motor off
and check the motor shaft to see if it is tight. Check the pump shaft; if it is free and the motor will
not run, replace the flame detector located in the burner housing. Turn on the current and reset the
control (relay). If the motor still does not run, replace the control (relay). If motor hums and gets hot,
replace the motor.
5. If the burner ignites and runs a short time (10 to 15 seconds) and goes out on safety, replace the
flame detector. If the burner still runs only a short time, replace the control.
Regular maintenance
will keep the water
heater operating at
peak efficiency. The
tank can fail prematurely from the
accumulation of lime
and sediment in the
bottom, excessive
pressure and/or corrosion.

–5–
6. The smell of oil or combustion products may be caused by poor draft or lack of combustion air.
Remove and clean the electrode assembly and check the draft in the connector directly above the
heater. There should be at least .01 inches W.C.. draft (pull) or greater.
Lime and sediment: Such accumulations can be controlled to an extent by softening the water. The
tank should be inspected every six months by draining the tank, removing the hand hole cover, and
making a visual check of the tank interior. If lime (or sediment) has accumulated, it should be removed
by use of a commercial lime dissolving chemical or by scraping loose the deposit and flushing it away
through the hand hole or drain.
Excessive pressure is controlled by the T&P relief valve. Water expands when heated and the extra
volume of water must have a place to go. If water cannot expand into the cold water line because of a
check valve, pressure builds as the water heats. The pressure relief valve opens, and dumps the extra
volume of water. If the relief valve is faulty or none has been installed, the tank can fail due to this excessive pressure. Open the relief valve at least once a year to make sure the seat is not stuck.
Caution: Before opening the relief valve be certain that the discharge line directs the water away from
anything that could be damaged or would block the flow of water to the drain. Stand away from the
outlet to avoid contact with the water.
Rods are installed in the head of the tank to help prevent corrosion of the tank. When inspecting the
tank interior for lime or sediment accumulations, also inspect the condition of the anode rods. When
either rod has eroded to about one third of its original diameter, it should be replaced.
Vent system should be checked at least once a year for damage and/or blockage.
If the water heater is to be shut off during cold weather, the tank and water lines should be drained to
prevent freezing and piping damage. Please see warning on hydrogen gas buildup on page 1. IMPORTANT! The water heater warranty will be invalid if the tank fails due to excessive pressure, the accumulation of lime or sediment, corrosion, or freezing. The Bock Water Heaters warranty (back page)
explicitly documents further causes of invalidation.

Our liability, in the vent of leakage or other malfunction, is strictly limited to repair or replacement of the defective heater or part as provided herein. We are not responsible hereunder for incidental property damage or personal injury, consequential costs or damage.
OWNER RESPONSIBILITY: At the company’s request, the owner is to return to the factory at Madison, WI any part, including the tank,
