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.

Fig. 3 Heating system control with Aquasmart control (main

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.

the boiler)

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.

We reserve the right to make any changes due to techincal modifications!

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.

Fig. 5 Burner lock-out condition

1Burner

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.
