2 Product Description
The G215 boiler is a low temperature boiler for oil or gas
firing with a burner for both outdoor reset operation with
a suitable control or for cold start operation with a
Honeywell aquastat.
Your heating contractor or installer has equipped the
boiler with an approved burner.
The boiler consists of the following components:
–Logamatic control panel or Aquasmart control
–Boiler jacket
–Boiler block with insulation
–Customized burner
The control panel controls boiler temperature and
controls burner and pump operation.
The boiler can also be equipped with a Aquasmart
control for a more simple control of boiler operation.
The boiler jacket reduces energy loss and noice levels.
The boiler block transfers the heat produced by the
burning of the fuel to the boiler water. The insulation
reduces the standby loss.

System Operation3
3 System Operation
3.1 Turning on the system
Make sure prior to turning the system on:
–that the operating pressure is sufficient.
–that main fuel shut-off valve has been opened.
–that the main emergency switch is turned on.
When using a Buderus Logamatic control (Fig. 2)
zSet the adjustable aquastat dial on “AUT“ .
zSet the main switch to position "I". This turns on the
entire heating system.
When using a Aquasmart control (Fig. 3)
zTurn on the main system switch (Position "ON").
This activates the entire heating system.
3.2 Turning off the system
Buderus Logamatic Control (Fig. 2)
zTurn off main service switch (Position "0") at control.
This shuts off the boiler as well as all other system
components.
With Aquasmart control (Fig. 3)
zTurn off main service switch (Position "OFF") This
shuts off the entire system and all its components.
zShut off main fuel supply with main fuel valve.

NOTICE
Information regarding the operation of the
Logamatic control, such as setting of
temperatures etc, can be found in the
Îdocumentation supplied with the
control.

service switch)
CAREFUL!
SYSTEM DAMAGE
due to freezing conditions.
When the system is not in operation, the
potential for a freeze-up exists.
zKeep the system in operation as much
as possible.
zProtect the system against freeze-ups
by either filling the system with a 50%
glycol solution, or by draining both the
heating and DHW systems at their
lowest points.

3.3 Emergency operation
Proceed in the following manner in an emergency
situation, such as a fire:
zShut off fuel supply at the main shut off valve.
zShut off the heating system by means of the main
service switch.
3.4 Testing system pressure: adding make-up water and venting the system
3.4.1 When to test system pressure?
Newly added make-up water tends to reduce its volume
within the first few days due to elimination of entrained
air. This may lead to air build-up and possible system
noise.
zCheck newly started systems daily for system
pressure and bleed radiators if necessary.
zCheck system pressure on a monthly basis and add
make-up water automatically and possibly bleed the
radiators.
3.4.2 Testing system pressure
The system operating pressure must be at least 12 to
15 psi (1 bar). The specific recommended
zThe specific recommended test pressure can be
found on Îpage 2. of this manual.
zRead off the pressure (psi) and temperature (°F) at
the P & T guage located at the supply side of the
boiler.
zWhen the system pressure drops below 12 to 15 psi,
add make-up water to the system.
3.4.3 Adding Make-up Water and Venting of the
system
Have your heating contractor or installer indicate to you
the location of the automatic feed valve and the
automatic air elimininator.

System Operation3
zConnect water hose to boiler drain and water supply.
zSlowly fill the boiler system. Observe water pressure
of the heating system.
zClose the water supply when reaching the desired
system pressure.
zBleed sir from the system at radiator air vents and
other locations.
zWhen the system pressure drops due to air venting,
add more water to the system.
zDisconnect water hose from boiler.
Please contact your heating contractor or service
company when you are changing your heating system to
another fuel, or when you are switching over to fuel with
different specifications.
CAREFUL!
SYTEM DAMAGE
due to thermal stresses.
When the boiler is hot and cold water is
being added, this may lead to thermal
stresses and shock the boiler. This may
lead to a cracked boiler.
zAdd only make-up water to the boiler
when the boiler temperature below 100
F. (Or when the cold feed is piped in on
the supply side of the boiler so that cold
make-up water is first sent into the
system).
WARNING!
SYSTEM DAMAGE
Due to frequent filling of system.
When you need to frequently add water to
the system, you can cause damage to the
system due to fresh water entry leading to
corrosion and internal lime build-up.
zCheck with your local service company
or contractor if you can use regular
untreated tap water, or if the fill water
must be treated.
zPlease inform your installing contractor
or service company, if frequent use of
make-up water is necessary.
CAUTION!
SYSTEM DAMAGE
due to incorrect fuel.
zUse only the designated fuel listed on
Îpage 2 of this manual.

3.5 Why is regular maintenance important?
Heating systems require regular maintenance for the
following reasons:
–To maintain high efficiency operation and minimal
use of fuel.
–To maintain a high level of system reliability.
–To keep environmental emissions at a minimum.
zWe recommend that you sign a yearly maintenance
agreement with your fuel oil company or service
company.
CAUTION!
BOILER DAMAGE
due to contaminated combustion air.
zNever use or store chlorine containing
cleaning agents or hydro-carbon-
halogen type compounds (such as
sprays, cleaning and dissolving agents,
paints, glues and alike) in the boiler
room or near the combustion air
passages.
zAvoid excessive dust generation.
CAREFUL!
SYSTEM DAMAGE
due to water.
zIn case of flooding conditions, shut of
the fuel supply and electrically
disconnect the heating system
(ÎChapter 3.2, page 6).
zHave your system fully checked by a
qualified heating contractor or service
company prior to putting it back in
operation.
zHave all components, that have been in
contact with water, replaced by your
contractor or service company.
CAREFUL!
SYSTEM DAMAGE
due to missing or poorly performed boiler
cleaning and maintenance.
zHave your heating system once
annually checked, cleaned and
serviced by a qualified service
company or contractor.

Trouble Shooting your Heating System4
4 Trouble Shooting your Heating System
Two different type of problems can be identified:
–burner related problems, or
–problems related with the control system and heating
system.
An alarm light on the burner will typically light up during
a burner lock-out condition (ÎSee burner manual).
Typically this problem is resolved by pressing the burner
reset button. Press the burner reset button once. If the
burner does NOT fire, contact your local service
company for assistance.
Problems related to the control panel and/or heating
system itself, are typically shown on the display of the
control panel, if the boiler is so equipped. Further
information can be found in the Îmanuals supplied
with the control panel.
Burner lock-out condition
zPress the burner reset button once. If the burner
does NOT fire, contact your local service company
for assistance.

CAUTION!
SYSTEM DAMAGE
due to freezing conditions.
When the heating system is not in
operation due to a problem condition, the
possibility of a freeze-up may exist.
zTry to locate and resolve the problem.
zIf not possible, contact your local con-
tractor or service company.
