If you smell smoke, there is an explosive danger due to flammable fumes. Follow these steps immediately:

• No open fire! Do not smoke! Do not use a lighter!

• Avoid generating sparks! Do not use an electrical switch, or telephone, electrical plug or bell!

• Shut off main gas /oil supply!

• Open windows and doors!

• Notify home owner, but do not use a door bell or phone!

• Leave the building!

• Notify the gas utility or fuel oil service company immediately from a remote location.

• Possibly notify the police or fire department.

• Immediately leave the building when hearing or seeing discharging gases!

To prevent poisoning from insufficient combustion air and to avoid fire hazards, please adhere to the following placement and environmental requirements:

• Make sure that the combustion air supply and discharge openings are not reduced or closed off.

• Keep doors to the boiler room closed and do not block louvers in the boiler room door.

• Protect the boiler room and avoid rodents and birds from entering and blocking the air openings.

• The boiler cannot be placed in operation if the above issues have not been resolved.

• Make sure that flammable or liquid materials are not placed near the boiler.

Before turning the system on, make sure of the following:

• that the operating pressure is sufficient.

• that the main fuel shut-off valve has been opened.

• that the main emergency switch is turned on.

When using a Buderus Logamatic control:

• Set the adjustable aquastat dial on “AUT”.

• Set the main switch to position “I”. This turns on the entire heating system.

When using an Aquasmart control:

• Turn on the main system switch (Position “ON”). This activates the entire heating system.

With a Buderus Logamatic Control:

• Turn off main service switch (Position “0”) at control. This shuts off the boiler as well as all other system components.

With an Aquasmart control:

• Turn off main service switch (Position “OFF”). This shuts off the entire system and all its components.

After turning off the control, you should also shut off the main fuel supply with the main fuel valve.

When the system is not in operation, the potential for a freeze-up exists. To protect the system:

• Keep the system in operation as much as possible.

• Protect 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.

In an emergency situation, such as a fire, proceed in the following manner:

• Shut off fuel supply at the main shut off valve.

• Shut off the heating system by means of the main service switch.

When to test system pressure:

• Check newly started systems daily for system pressure and bleed radiators if necessary.

• Check system pressure on a monthly basis and add make-up water automatically and possibly bleed the radiators.

How to test system pressure:

The system operating pressure must be at least 12 to 15 psi (1 bar). The specific recommended test pressure can be found in your manual.

• Read off the pressure (psi) and temperature (°F) at the P & T gauge located at the supply side of the boiler.

• When the system pressure drops below 12 to 15 psi, add make-up water to the system.

To prevent thermal stress and a cracked boiler, only add make-up water when the boiler temperature is 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).

Have your heating contractor or installer indicate to you the location of the automatic feed valve and the automatic air eliminator.

• Connect a water hose to the boiler drain and water supply.

• Slowly fill the boiler system. Observe the water pressure of the heating system.

• Close the water supply when reaching the desired system pressure.

• Bleed air from the system at radiator air vents and other locations.

• When the system pressure drops due to air venting, add more water to the system.

• Disconnect the water hose from the boiler.

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.

• Check with your local service company or contractor if you can use regular untreated tap water, or if the fill water must be treated.

• Please inform your installing contractor or service company, if frequent use of make-up water is necessary.

Contaminated Combustion Air:

• Never 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.

• Avoid excessive dust generation.

Water Damage:

• In case of flooding conditions, shut off the fuel supply and electrically disconnect the heating system.

• Have your system fully checked by a qualified heating contractor or service company prior to putting it back in operation.

• Have all components that have been in contact with water replaced by your contractor or service company.

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.

To avoid system damage due to missing or poorly performed boiler cleaning and maintenance, have your heating system checked, cleaned, and serviced once annually by a qualified service company or contractor. We recommend that you sign a yearly maintenance agreement with your fuel oil company or service company.

An alarm light on the burner will typically light up during a burner lock-out condition. To resolve this:

• Press the burner reset button once. If the burner does NOT fire, contact your local service company for assistance.

When the heating system is not in operation due to a problem condition, the possibility of a freeze-up may exist.

• Try to locate and resolve the problem.

• If not possible, contact your local contractor or service company.

The system pressure settings are as follows:
