The optional DES is to be used in conjunction

with the EV boiler for indoor installations requiring

through the wall venting, The DES is designed as
an integral part of the EV boiler, eliminating the

need for a power venter.

Oil boiler DES kits include an oil burner with
adjustable post purge timer and solenoid valve.

For through the wall venting, this post purge burner
must be used in place of the standard burner that is

furnished with the boiler.

Selection of boiler size should be based upon "Net

I=B+R Rating MBH being equal to or greater than
the calculated heat loss of the building.

These boilers are low pressure sectional cast
iron boilers constructed and hydrostatically tested
for a maximum working pressure of 50 psi in
accordance with A.S.M.E. (American Society of

Mechanical Engineers) Section IV Standards for
cast iron heating boilers. They are capacity rated
in accordance with the code of the Hydronics

Institute.

These boilers operate on #2 Heating Oil, Natural
Gas, or Propane Gas, with the proper burner.

IMPORTANT

Standard indoor EV Series boilers are furnished
as knockdown boilers and are shipped as four

components (w/o DES) or five components (with
DES) are shown below:

• basic boiler assembly (oil and gas identical)

• boiler jacket (oil and gas identical)

• accessory kit (oil and gas identical)

• burner (oil or gas, without post purge)

• DES parts (include post purge oil burner for
oil-fired burners)

Weatherproof (outdoor) EV Series boilers are

furnished as knockdown boilers only and are

shipped as five components as shown below:

• basic boiler assembly (oil and gas identical)

• weatherproof boiler jacket (oil and gas
identical)

• exhaust cap, pipe, and weather collar (oil
and gas identical)

• accessory kit (oil and gas identical)

• burner (oil or gas)

On knockdown oil burners, the oil burner nozzle
is not included. Correctly sized nozzle must be

installed prior to startup.

Indoor oil-fired models DPFO (3, 4, 5, 3T, 4T,
5T) without direct exhaust system are available

as packaged boilers, in which case an oil burner
nozzle for one of three specified firing rates wilt
be factory installed in the oil burner.

Gas boilers, knockdown or packaged, may be
ordered to have their burners equipped for either

natural or propane gas with the proper flame
retention head and orifice to match the input
specified by the purchaser. However, a boiler

drawn from the stock of a wholesale distributor will
normally be equipped with a burner with a G-O

flame retention head and an orifice to fire natural

as in the minimum input range of a G-O head.

,J

• Read the installation manual before beginning

the installation. Failure to follow the rules for

safe operation and the instructions can cause a
malfunction of the boiler and result, serious bodily
injury, and/or property damage.

• Check your local codes and utility requirements
before installation. The installation must be in

accordance with their directives, or, in their absence,

follow NFPA Installation Codes and good industry

practice.

• Before servicing, allow boiler to coot. Always shut

off any electricity and oil to boiler when working on

it. This will prevent any electrical shocks or burns.

• Inspect oil lines and connections for leaks.

• Be certain oil burner nozzle or gas orifice is size

required. Over-firing will result in early failure of
the boiler sections. This will cause dangerous
operation.

• Never vent this boiler into an enclosed space.

Always vent to the outside. Never vent to another

room or inside a building.

• Be sure there is adequate air supply for complete

combustion.

• Follow a regular service and maintenance

schedule for efficient and safe operation.

• Keep boiler area clean and free of combustible

material, gasoline, and other flammable vapors

and liquids.

• Proper through-the-walt venting requires use of

complete DES (oil-fired units only).

• Oil and gas burners are not do-it-yourself items.
This boiler must be installed and serviced by
qualified professionals using combustion test

instruments.

• Be aware when piping the relief valve if the

system pressure exceeds the safe limit of 30 Ibs.

per square inch, the relief valve will automatically
open. Lifting of the relief valve can discharge large
quantities of steam and hot water, which may
damage the surroundings. Before installing the

relief valve, read the manufacturer's instructions

and the maintenance section of the manual on

relief valves.

• Frequent and mysterious lifting of the relief valve
may be a sign of an improperly sized expansion

tank. Installation and sizing of the expansion tank
must consider the heating system's total water

volume, temperature, boiler initial fill pressure, and
system arrangement. For proper installation and

maintenance follow the guidelines established by
ECR and the manufacturer.

• Expansion tank performance and life expectancy
can be hindered by overfilling the boiler. ECR

recommends an initial fill pressure of 10 - 12 psig.
For higher fill pressures, the expansion tank's air

charge will need to match the fill pressure. Consult
the manufacturer's guidelines for sizing and

selection.

• Purging the heating system of air and gases
during the boiler's initial commissioning is critical

for proper circulation and quiet performance. Once
the air and gases are purged, for boiler installations

using float type vents, the air vents should be closed
for normal operation. If air is heard or noticed by a

loss of heat, purge the system and open the vents
for a short period of time.

Check to be sure you have the right size boiler
before starting the installation. See rating and

capacity tables on preceding pages. Check the

rating plate on the right side of the boiler.

You must see that the boiler is supplied with the

proper fuel, fresh air for combustion, and a suitable
electrical supply. Also, the boiler must be connected

to a suitable venting system and an adequate piping
system. Finally, a thermostat, properly located, is

needed for control of the heating system. If you

have any doubts as to the various requirements,

check with local authorities and obtain professional

help where needed.
These installation instructions are vital to the proper

and safe operation of the heating system. Take the
time to be sure they are carefully followed.

1. Place boiler at a location as centralized to the

piping system and as close to the chimney or vent
terminal as possible to minimize condensation. At
input rates up to 1.75 gph (245,000 Btu/hr), the
supply and return from radiation may be piped on

the same end of the boiler. At higher rates, it is
recommended that the supply be piped from the
rear of the boiler and the return be piped from the
front of the boiler. Coordinate jacket installation
with piping. See "Jacket Assembly Instructions"

and "Piping Diagrams" in this manual for more
information.

2. See Figure 4 for installation on combustible
flooring. If necessary, place metal shims beneath

feet to ensure a level unit.

3. Accessibility clearances must take precedence
over fire protection clearances. Allow at least 24"
for servicing at the tankless and burner sides of the

unit. Allow at least 18" at a side where passage is
required for access to another side for servicing.

A 6" clearance from combustible material on all
sides and the top is recommended. 18" clearance

is necessary between smoke pipe and nearest
combustible material. See NFPA 31, latest revision,

for safe methods to reduce clearances where

necessary. NFPA publications are available at
Battery Park, Quincy, MA 02269.

1. Antifreeze added to boilers must be non-toxic,

and must of a type specifically intended for use
in closed hydronic heating systems. Under no

circumstances should automotive antifreeze be
used.

2. Use of antifreeze in any boiler may reduce
capacity by 10% or more and increase fuel
consumption. Tanktess coil performance will fall as

concentration of antifreeze is increased. See below
for water volumes of boilers and piping.

3. Because antifreeze forms slush rather than hard
ice, it is safe to protect only to 10 degrees above

coldest temperature anticipated provided slush
formed can move towards expansion tank.

As efficiencies increase and slack temperatures
decrease, it becomes increasingly important to keep

boiler warm enough to discourage condensation. All

steel and cast-iron boilers can rust badly if operated
for extended periods at water temperatures below

140 and chimneys can be damaged as well.

The purpose of the by-pass shown in Figure 6

(above) is to permit the boiler to warm up faster

than the radiation system, thereby decreasing
the potential for condensation in both boiler and

chimney.

FIG.7-TYPICALTANKLESSCOILPIPING

Use the following setting for the first adjustment:

High Setting .............. 180°F

Low Setting ............... 160°F

Differential .................. 20°F

These settings may be altered based on the heating
system response. During very cold weather if the

heating system does not provide quite enough
heat, the high limit control setting may be raised to

a maximum of 200°F. If more domestic hot water is
required, the low limit control setting may also be

raised to a maximum of 180°F. Whenever adjusting

either the high or low limit, the high limit control
setting must be set at least 20°F above the low

limit. The differential control setting is typically 20°F
but may be adjusted to vary the time it takes the
burner to respond to a call for domestic hot water.

1. Cold standby is suitable only when thermostatic

union is used with piping bypass shown in Figure 6.

2. A change in control wiring is also required. To

prevent excessive condensation, please contact

factory before making this change.

3. Owners of non-tanktess boilers often object to the

burner starting when space heat is not required. To
avoid this, an optional outside thermostat may be
used to shut down the system totally when outside

temperature is above a specific limit set by the

homeowner. See wiring diagrams.

1. STANDARD BECKETT AFG OR CF375
OIL BURNER: A Beckett model ADF oil burner

is normally supplied with boilers to be fired at

2.00 gph or less. It is equipped with an F3 flame
retention head, the size most commonly used. It is

possible the head must be changed to match the
nozzle firing rate required, and it is recommended

the installer carry a complete assortment of Beckett
flame retention heads. When head rating overlap,

a smaller head with air shutter fairly well open
will generally provide better combustion than a

larger head with air shutter near closed. See head
size selection chart in this manual. For Beckett

burners at firing rates above 2.00 gph, a Beckett
model CF375 burner is required, and is supplied if

specified by purchaser.

2. OPTIONAL RIELLO 40 SERIES OIL BURNER:
Riello 40 series oil burner is optional. Model F5

is used for firing rates from 0.90 to 1.50 gph, and
Model F10 is used for firing rates from 1.60 to 3.00

gph. Model F5 or F10 is supplied if specified by

purchaser. For firing rates below 0.90 gph, a Model
F3 is required, and must be purchased from a Rietto

distributor.

3. On knockdown boilers, the burner is not supplied
with a nozzle. The correct nozzle is the smallest

which will do the job properly. Long continuous runs
with minimum starts and stops conserve the most
energy. The nozzle which provides the highest C0_

with the least smoke for a particular application

is always recommended. Beckett oil burners are
supplied with pump pressure set at 140 psi. Nozzle

output will be approximately 18% greater than that

at 100 psi. Pump pressure on Rietto burners should
be adjusted according to settings in "Suggested
Nozzles and Settings for Riello Burners" on the

next page.

With all high efficiency boilers, care must be taken
to minimize condensation. Therefore, cold standby
is not recommended and may be used only with a
piping, bypass as shown on Figure 6. This requires

a change in control wiring. Please contact factory
prior to making that change.

When cold standby is not utilized, the homeowner
might object to the burner starting when space heat

is not required. To avoid this, an optional outside
thermostat may be used to shut down the system
when outside temperature is above a specific limit
set by the homeowner. When outside thermostat is

not used, Jumper T-T Terminals on relay.

These settings may be altered based on the heating
system response. During very cold weather if the

heating system does not provide quite enough
heat, the high limit control setting may be raised

to a maximum of 200°F. If more domestic hot
water is required, the low limit control setting may

also be raised to a maximum of 180°F. Whenever
adjusting either the high or low limit the high limit

control setting must be set at least 20°F above the
low limit. The differential control setting is typically

20°F above the low limit. The differential control
setting is typically 20°F but may be adjusted to vary

the time it takes the burner to respond to a call for
domestic hot water.

1. A Beckett model AFG post-purge oil burner
is normally supplied with boilers to be fired at

2.00 gph or less. It is equipped with an F3 flame

retention head, the size most commonly used. It is
possible the head must be changed to match the

nozzle firing rate required, and it is recommended
the installer carry a complete assortment of Beckett
flame retention heads. When head ratings overlap,
a smaller head with air shutter fairly well open wilt
generally provide better combustion than a larger

head with air shutter near closed.

2. At firing rates above 2.00 gph, a special Beckett
model CF375 burner must be used and is supplied
if specified by purchaser.

3. Post-purge oil burners are supplied with pump
pressure set at 140 psi. Nozzle output wilt be
approximately 18% grater than that at 100 psi.

4. The burner is not supplied with a nozzle. The
correct nozzle is the smallest which will do the

job properly. Long continuous runs with minimum

starts and stops conserve the most energy. The
nozzle which provides the highest C% with the

least smoke for a particular application is always
recommended.

A WARNING A

5. Using acorn nuts, studs, and washers from
hardware package, fasten burner to mounting plate.
Do not disturb chamber when inserting firing head.

6. Mount L8151 control on boiler jacket above and
to the right of burner using sheet metal screws in

holes located in jacket. Wiring harness is provided.

When welt is used at the rear of a larger boiler, it

might be necessary to relocate the control with
longer wiring not provided.

7. If boiler has a tanktess coil, insert well for the
L8151 remote bulb in coil plate. Run capillary tube

through sight glass opening in jacket.

8. If a tankless coil is not used, install 3A" welt

and bulb with a bushing either in the 1½" supply
opening opposite the one used to feed radiation,
or in a reducing tee in the 1½" supply opening that

feeds radiation.

9. Mount overfire pressure switch at upper right

of burner on screws already in jacket. Burner will

shut down if overfire pressure reaches .35" H20 due
to a plugged flue or high wind. See "Vent Safety

11. Install Gar-Ber filter as provided rather than a

standard filter between burner and oil storage tank.

12. Before making control adjustments, verify that

all fuel, water, and electrical connections have been
made in accordance with the regulations of the

National Fire Prevention Association, the National
Electrical Code, and/or local regulations.

13. STARTUPANDADJUSTMENT: Start and adjust
burner according to manufacturer's instructions

contained in burner carton or included with boiler
and pay special attention to the following:

a. As the name suggests, this boiler is designed
to produce the ultimate in usable heat from a
gallon of fuel oil.

b. With chamber fully warmed up, find the

highest CO 2 level at which zero Smoke can be

maintained. Then add extra air until CO 2falls off

1%. Final setting should be at least 11% CO 2. If

unable to obtain that reading, check for internal
oil leaks, incorrect flame retention head, or faulty

or incorrect nozzle.

14. POST PURGE TIMING: With through-the-wall
venting there is no overfire draft present after the
burner shuts down. Therefore a post purge must be
used to prevent the hot chamber from overheating

the nozzle.

The post purge timer is part of the Honeywell
intermittent primary control, which is located on the
Beckett oil burner. The post purge time has been

preset to 4 minutes but may be adjusted to 0, 2,
4, or 6 minutes by adjusting the switches on the
side of the intermittent primary control. With a stack
thermometer in place, the boiler fully warmed up
(200°F or more), and the boiler running, turn the

high limit control on the aquastat all the way down.
The burner motor should then be running with the

flame off (i.e., in post purge). Measure the time it
takes from the flame off until the stack temperature
falls to the same temperature as the boiler water.
Adjust the post purge timer to nearest time interval,

always rounding up if possible. For example, if the
time measured is 3 minutes and 20 seconds, then

set the post purge timer at 4 minutes.

Whenever the nozzle is removed for service, check
for varnish forming on the outside of the nozzle. If

carbon and varnish do not wipe off easily, increase
the post purge time.

15. LIMITED RECYCLEAND LIMITED RESET: The

Honeywell R7184P1031 interrupted-duty primary

control utilizes two safety features to protect the

boiler from being saturated with oil. Limited recycle
will allow the burner 3 attempts to ignite, if ignition

is unproven the control locks out. The control's

reset button can then be pressed. The limited reset
feature will allow the burner to be reset 3 times

before it locks out. To unlock the control requires
the reset button to be held for 30 seconds.

16. ELECTRICAL WIRING: Wiring should conform

with the latest edition of the National Electrical Code
ANSI/NFPA No. 70 in the United States and the CSA

C22.1 Canadian Electrical Code in Canada and/or
the local authority having jurisdiction. A separate

electrical circuit should be run from the entry box
with a fused disconnect switch in this circuit. Refer

to wiring diagrams for suggested circuitry and
field wiring. Wiring for zone valve installations are
furnished with zone valve packages.

heating system does not provide quite enough

heat, the high limit control setting may be raised

to a maximum of 200°F. If more domestic hot
water is required, the low limit control setting may

also be raised to a maximum of 180°F. Whenever

adjusting either the high or low limit the high limit

control differential control setting is typically 20°F

above the low limit. The differential control setting is
typically 20°F but may be adjusted to vary the time

it takes the burner to respond to a call for domestic

hot water.

Connect gas service meter to control assembly
in accordance with the latest revision of the ANSI

Z223.1 and local codes or utility. A ground joint
union should be installed for easy removal of gas

control for servicing. A drip or trap must be installed
at the bottom of a vertical section of piping at the
inlet to the boiler. A pipe compound resistant to the
action of liquefied petroleum gases must be used
on all threaded pipe connections. Check with the

local utility for location of manual shutoff valve.

supply piping system at test pressures equal to or

less than 0.5 psi (3.5 kPa). The boiler and its gas

connection must be leak tested before placing the

boiler in operation.

After placing the boiler in operation, the ignition
system safely shutoff device must be tested. The

method of testing must be specified in detail. A
sediment trap must be provided upstream of the gas

controls and location of manual main shutoff valve

must be outside the jacket when codes require.

the correct size to match the boiler input rate

required for this particular installation.

c. Fasten burner to burner mounting plate using
three studs, washers, and acorn nuts from

hardware package. Be very careful to avoid

disturbing combustion chamber when inserting
air tube. Retention head must be set flush with

inside watt of combustion chamber.

13. Connect piping to distribution system referring to
Figure 14 for systems with domestic water heating

or to Figure 15 for systems without.

14. Verify that fuet, water, and electrical connections
have been made in conformance with all applicable
codes.

15. Fill and test boiler and systems. Weatherproof
space heating boilers require antifreeze. See
"Antifreeze" on this page for more information.

16. Cover all outdoor piping with weather-resistant
insulation.

17. Start burner according to manufacturer's
instructions and make combustion tests. It is

suggested that the short length of smoke pipe be
installed temporarily for ease in making tests. (See

startup and adjustment instructions for oil and gas
installations in this manual for more information.)

18. Referring again to Figure 16, fasten front jacket
panel (#9) in position with sheet metal screws and
install jacket top (#5).

19. Install exhaust assembly with parts 6, 7, and

8. The exhaust cap is made to spring inside the
short length of smoke pipe. A tourniquet made of

wire or a large hose clamp may be used to reduce
the diameter so that it will fit inside the pipe. Two or

three hose clamps in series may be used when a

large one is not available.

1. Antifreeze added to boilers must be non-toxic and
must be of a type specifically intended for use in closed

hydronic heating systems. Under no circumstances

should automotive antifreeze be used.

2. Use of antifreeze in any boiler may reduce capacity
by 10% or more and increase fuel consumption.

Tanktess coil performance wilt fall as concentration
of antifreeze is increased.

3. Because antifreeze forms slush rather than hard
ice, it is safe to protect only to 10 degrees above

coldest temperature anticipated provided slush

formed can move towards expansion tank.

As boiler temperature increases, air wilt move from
top of boiler toward float vent even if lower. As

boiler temperature decreases, water will move from

expansion tank toward boiler. (See Figure 13.)

This boiler was designed to produce the ultimate in
usable heat from a gallon of fuel oil.

With chamber fully warmed up, find highest CO 2
level at which zero smoke can be maintained.

Then add extra air until CO 2 falls off about 1%.
Final setting should be at least 11% CO 2. If unable

to obtain that reading, check for internal oil leaks,
incorrect flame retention head of faulty or incorrect

nozzle. Draft wilt vary as air is adjusted. It should
be left at as near zero as possible at breeching.

The correct nozzle is the smallest which will do the

job properly. Long continuous runs with minimum

starts and stops conserve the most energy. The
nozzle which provides the highest CO 2 with the

least smoke for a particular application is always
recommended.

A Beckett model AFG oil burner is used to fire
boilers at 2.00 gph or less. At firing rates above 2.00
gph, a Beckett model CF375 is required. A model

AFG burner shipped with your EV Series boiler

is equipped with an F3 flame retention head, the

size most commonly used. It is possible the head

must be changed to match the nozzle firing rate
required, and it is recommended the installer carry
a complete assortment of Beckett flame retention

heads. When head ratings overlap, a smaller head

with air shutter fairly well open will generally provide

better combustion than a larger head with air shutter
near closed. See head size selection chart on page

21. For firing rates under 1.00 gph. see page 18 for
information on using low firing rate baffles.

It should be recognized that the description of spray
patterns might vary between nozzle manufacturers.
In any case the nozzle recommended is that which

provides the highest CO 2with the least smoke for a
particular application.

RELIMINARY AIR SETTINGS FOR VARIOUS I

IRING RATES AND BURNERS ARE SHOWN I

N PAGE 16. 1"")

Use the following setting for the first adjustment:

High Setting .............. 180°F

Low Setting ............... 160°F

Differential .................. 20°F

These settings may be altered based on the heating
system response. During very cold weather if the

heating system, does not provide quite enough
heat, the high limit control setting may be raised to

a maximum of 200°F. If more domestic hot water is
required, the low limit control setting may also be

raised to a maximum of 180°F. Whenever adjusting

either the high or low limit the high limit control

setting must be set at least 20°F above the low
limit. The differential control setting is typically 20°F

but may be adjusted to vary the time it takes the
burner to respond to a call for domestic hot water.

AIR ADJUSTMENT IS NOT FACTORY SET:
When first firing burner, start with air shutter much
nearer closed than final setting anticipated. (At 70

MBH, shutter must be fully closed because some
air always bypasses shutter.) With chamber fully

warmed up, find highest CO 2 level at which CO of

less than 50 ppm can be maintained. Final setting
should be at least 10% CO 2. If unable to obtain
that reading, check for air leaks, incorrect flame

retention head or educator tube not centered. CO 2
readings as high as 11% are acceptable provided

CO does not exceed 50 ppm. The correct input rate
is the smallest which wilt do the job properly. Long

continuous runs with minimum starts and stops
conserve the most energy.

ndensa!ion in boi!er and !!ue: J

An EV Series gas boiler ordered individually from the
factory is shipped with an Adams burner equipped

with the proper flame retention head to match

the boiler input rate requested by the purchaser.
However, burners drawn from a wholesale

distributor's stock are shipped with GO heads, and
it is recommended that the installer carry a complete

assortment of Adams flame retention heads in
order to change heads when necessary to match

the boiler input rate. When head ratings overlap,
a smaller head employed with air shutter fairly

well open will generally provide better combustion

than a larger head with air shutter near closed.
The information on pages 20-21, an excerpt from

the Adams burner instruction manual, is offered to
assist in selecting the correct head and orifice for

the Adams gas burner.

Adams burners supplied from stock with EV Series

boilers are equipped with a GO flame retention
head and with two orifice plates, one inserted at

each end of the orifice spring. The primary orifice

(mounted in position ready for firing) is the smallest
at which the burner should be fired using natural

gas. The auxiliary orifice (stained red in color) is
the smallest at which the burner should be fired

with propane. The two orifices are interchangeable

according to the fuel to be used, and either should
be reamed out if a larger firing rate is desired.

Check after reaming with the proper size drill. (See

sizing charts in this manual.)

High Setting - Not less than 200°F, 20°F or more
above Low Setting.

Low Setting - Not less than 180°F for best
tankless coil output. Lower settings may be used

when tanktess coil is not a factor. Cold standby is

only suitable when thermostatic union (available

from ECR) is used with a bypass. Call factory for

instructions to change wiring.
Differential - 20°F typical. May be changed to

match system.

OTE: If public utility regulations in your community require"_

beling of the boiler with burner head size and firing rate, I
ease use label in literature envelope for this purpose. .._

The gas input for natural gas can be determined by
timing the gas meter. To vary the gas input, install

the nearest size orifice; then adjust the pressure

2. Before operating, smell all around the appliance for

gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.

3. Use only your hand to push in or turn the gas
control knob. Never use tools. If the knob wilt not

push in or turn by hand, don't try to repair it, call a

qualified service technician.

4. Do not use this appliance if any part has been
under water. Immediately call a qualified service
technician to inspect the appliance and to replace
any part of the control system and gas control which

has been under water.

1. STOP! Read the safety information in the user's

information manual.

2. Set thermostat to lowest setting.

3. Turn off all electric power to the appliance.

4. This appliance is equipped with an ignition de-
vice which automatically lights the pilot. DO NOT

TRY TO LIGHT THE PILOT BY HAND.

Remove the vent pipe at the base of the chimney or

flue and, using a mirror, check for obstruction.

The lever of the pressure relief valve on the boiler
should be operated periodically to make sure that

it is functioning properly. The pressure relief valve

should open before the water pressure exceeds
the 30 lb. reading on the gauge. If this pressure is
exceeded and the pressure relief valve leaks water
when the boiler is operating at normal pressures,

it should be immediately replaced. Corrosion can
build up rapidly at the valve seat and prevent its

functioning as a safety device.

,,_ WARNING ,,_

5. Turn gas control knob clockwise to "OFF."

6. Wait five (5) minutes to clear out any gas. If you
then smell gas, STOP, and follow in the safety infor-

mation "What To Do If You Smell Gas." If you don't
smell gas, go to the next step.

7. Turn gas control knob counterclockwise to
"ON ."

8. Turn on all electric power to the appliance.

9. Set thermostat to desired setting.

10.If the appliance will not operate, follow the in-
structions "To Turn Off Gas To Appliance" (below)

1. Check oil burner nozzle to make certain it is tight
in adapter. Burner mounting bolts should be tight.

2. Check electrode setting, as they may have been
jarred out of position during transportation.

3. Lubricate burner motor and circulator motor if re-

quired. Some circulators are water lubricated and
do not require oiling.

4. Set room thermostat to call for heat, or jump
thermostat contacts on the boiler control.

5. Open all oil line valves.

1. Set thermostat to lowest setting.

2. Turn off all electric power to the appliance if ser-
vice is to be performed.

3. Turn gas control knob clockwise to "OFF." DO

7. On one pipe fuel systems only, vent pump as
soon as burner starts. Allow oil to run until all traces

of air in the suction line disappear.

8. Turn "OFF" burner and install pressure gauge
port on pump.

The venting system should be inspected at the start
of each heating season. Check the vent pipe from

the boiler to the chimney for signs of deterioration
by rust or sagging joints. Repair if necessary.

9. Start burner again and check oil pressure for 140
pounds. Adjust if necessary.

DO NOT SET FIRE VISUALLY L _J

Instruments are the only reliable method to deter-
mine proper air adjustments. An improperly adjust-
ed burner causes soot and high fuel bills because
of incomplete combustion of the fuel oil. This in turn
may require excessive boiler maintenance, service

costs, and in some instances, house cleaning or re-
decorating. A competent service mechanic should
be consulted to make the proper adjustments with a

smoke tester, CO 2indicator and draft gauge. Bacha-
rach or Dwyer test kits include these instruments.

flame failure.

* Power Failure: Turn off main power supply
switch while burner is operating. When burn-

er stops, restore power and burner should
start.

A ¼" diameter slot is provided in the inspection
cover plate to take draft readings in the combustion

chamber. A ¼" diameter hole wilt be required in the
flue pipe between the boiler and barometric damper

(if used) to take draft, CO2, smoke and temperature
readings. Adjust air shutter on oil burner to obtain

a "trace" of smoke. Measure CO 2 at this point. In-
crease air adjustment to lower CO 2approximately

1%. Check to insure minimum -.02 w.c. "overfire"
draft, and zero smoke. If -.02 w.c. "overfire" draft can

not be maintained, changes and/or modifications
may be required in the venting or the chimney.

CHECK SAFETY CONTROL CIRCUIT after burner
adjustments have been made for satisfactory per-

formance.

1. High Limit Control: Remove cover and note

temperature setting. With the burner operat-

ing, decrease this setting to the minimum point.

When boiler water temperature exceeds this set
point, the high limit switch will open, shutting off

the power to the oil burner. Return setting to de-
sired high limit point. Burner should restart.

PREVENTIVE MAINTENANCE of an oil fired boiler
reduces operating costs. The boiler and vent pipe

should be inspected for accumulation of soot or

scale deposits periodically but at least once every

year before the start of each heating season. When

soot is present on the section walls and flueways,
improper combustion will result, causing additional
sooting and scaling until flueways are completely

closed. To remove soot and scale from the flue-

ways, remove top jacket panel, top clean-out plate,
open burner swing door.

PERIODIC INSPECTION and tightening of the tan-
kless heater/cover plate bolts wilt reduce the risk

Drain it until pressure is reduced below the safe
limit, Then have the valve replaced immediately,

The relief valve should be tested monthly, Refer to
valve manufacturer's instructions packaged with

relief valve,

The expansion tank may become waterlogged or

may receive an excess of air. Frequent automatic

opening of the relief valve indicates water logging. A

high boiler temperature accompanied by unusually
low radiation unit temperature (and "knocking")

indicates excess air in tank.

To correct either condition, close the valve between
the boiler and the tank, Drain the tank until it is

empty, Check all the tank plugs and fittings, Tighten

as necessary, Open the valve between the boiler
and tank, Water will rise to the normal height in the

tank if you have an automatic fill valve (otherwise,

manually refill the system),

If system is to remain out of service during freezing

weather and does not contain antifreeze, always

drain it completely. Water left in to freeze will
crack the pipes and/or boiler.

Visually inspect the entire venting system once
a month for any signs of leakage or deterioration.

If the vent shows any signs of leaking, replace it

immediately,

Do not connect directly to a drain, but leave an air
gap. No shut-off of any description shall be placed

between the safety relief valve and the boiler, or
on discharge pipes between such safety valves

and the atmosphere. Installation of the safety relief
valve shall conform to the ANSI/ASME Boiler and

pressure Vessel Code, Section IV. The manufacturer
is not responsible for any water damage.

Where used, antifreeze solution must be checked

at least once a year in the manner recommended by

the manufacturer of the antifreeze. The antifreeze

includes a corrosion inhibitor that can become

depleted in time, causing the solution to become

corrosive. It is important that this be checked and

the inhibitor be replenished or the system be refilled
with fresh antifreeze solution, whichever may be

required.

Antifreeze must be non-toxic, and of a type

specifically intended for use in closed hydronic
heating systems, Under no circumstances should

automotive antifreeze be used,

This valve should open automatically when the
system pressure exceeds the safe limits (30

pounds per square inch). Should it ever fail to
open under this condition, shut down your system.

The tanktess coil gasket should be checked at

least twice a year, for leakage, and replaced if
necessary.
