Sa ety, Installation and Warranty Requirement

 Fiberglass wool and ceramic iber

Materials

The state of California has listed the

airborne fibers of these materials as

possible cancer hazard through

inhalation. When handling these

materials, special care must be

applied.

Suppliers of ceramic fiber products

recommend the following first aid

measures:

- Respiratory tract (nose and throat)

irritation

If respiratory tract irritation

develops,

move the person to a dust free

location.

- Eye irritation

If eyes become irritated, flush

immediately with large amounts of

lukewarm water for at least 15

minutes. Eyelids should be held

away

from the eyeball to ensure thorough

insing. Do not rub eyes.

- Skin irritation

If skin becomes irritated, remove

soiled clothing. Do not rub or

scratch

exposed skin. Wash area of contact

thoroughly with soap and water.

Using a skin cream or lotion after

washing may be helpful.

- Gastrointestinal irritation

If gastrointestinal tract irritation

develops, move the person to a dust

free environment.

Suppliers of fiberglass wool

products

recommend the following

precautions

be taken when handling these

materials:

Precautionary measures

- Avoid breathing fiberglass dust

and

contact with skin and eyes.

- Use NIOSH approved dust/mist

respirator.

- Wear long-sleeved, loose fitting

clothing, gloves and eye protection.

- Wash work clothes separately

from

other clothing. Rinse washer

thoroughly.

- Operations such as sawing,

blowing,

tearout and spraying may generate

airborne fiber concentration

requiring

additional protection.

First aid measures

- If eye contact occurs, flush eyes

with

water to remove dust. If symptoms

persist, seek medical attention.

- If skin contact occurs, wash

affected

areas gently with soap and warm

water after handling





 Operation

Before operating the boiler, make sure you fully un-

derstand its method of operation. Your heating con-

tractor should always perform the initial start-up and

explain the system. Any warranty is null and void if

these instructions are not followed.





 Working on the equipment

All personnel working on the equipment or the heat-

ing system must have the proper quali ications and

hold all necessary licenses.

Ensure main power to equipment, heating system,

and all external controls has been deactivated. Close

main oil or gas shut-o valve. Take precautions in

all instances to avoid accidental activation of power

during

service work.





 Dangerous conditions

– Deactivate main power immediately.

– Close main gas or oil shut-off valve.





 Flue gas smell

– Deactivate heating equipment.

– Open windows and doors.

– Inform your heating contractor.





 Combustion air and ventilation air openings

Ensure that combustion air openings and ventilation

air openings in the mechanical room are open.





 Regular maintenance and service

The entire heating system must be cleaned and ser-

viced on a regular basis by a qualified heating

contractor or service agency to ensure reliable,

energy-efficient, and environmentally

friendly operation.

The build-up of soot on the heat exchanger raises

the flue gas temperature and reduces efficiency.

Indirect-fired domestic hot waterstorage tanks (if in-

stalled) must be serviced within two years (at most)

of the installation date, and regularly thereafter (see

Service Schedule starting).

For an overview of scheduled service procedures,

please see section entitled “Service Schedule”.

Keep boiler and boiler room clear and ree rom

combustible materials, gasoline and other lammable

vapors and liquids. Do not obstruct the low o

combustion and ventilation air. A quali ied heating

contractor must per orm all inspection, maintenance

and service.





 Important to know

Do not use this boiler if any part has been under, or

exposed to, water. Immediately call a qualified heat-

ing contractor to inspect the boiler and to replace

any part of the control

system and any gas control which has been under,

or exposed to water.





 Carbon monoxide

The U.S. Consumer roduct Safety

Commission strongly recommends the installation of

carbon monoxide detectors in buildings in which

gas-burning equipment is installed.

Carbon monoxide (CO) is a colorless, odorless gas,

which may be produced during incomplete combus-

tion of fuel and/or when the flame does not receive

an adequate supply of combustion air.

Carbon monoxide can cause severe personal injury

or loss of life.

Therefore, carbon monoxide detectors that are in

compliance with a nationally recognized standard

(e.g. ANSI/UL 2034-2002, CSA 6.19-01) should be

installed and maintained in buildings that contain

gas-burning equipment.

Note:

Viessmann does not test any detectors and makes

no representation regarding any brand or type of de-

tector.





 For sa e operation

We recommend that you frequently:

- Check for debris which could obstruct the flow of

flue gases. The vent or chimney must not be

blocked. Ablocked or partially blocked vent or chim-

ney can cause flue gases to leak

into the structure. Flue gases leaking into the house

can cause injury or death. Blocked or partially

blocked chimneys must have the blockage removed

by a qualified heating contractor.

- Check pressure gage for correct system (water)

pressure. Check for water on the floor from the dis-

charge pipe of the pressure relief valve or any other

pipe, pipe joint, valve or air

vent.

- Check for moisture, water, or appearance of rust

on the flue gas pipes, their joints as well as vent

dampers, or side wall vent terminals

(if so equipped).

- Ensure that nothing is obstructing the flow of

combustion and ventilation air and no chemicals,

garbage, gasoline, combustible materials, flammable

vapors and liquids are stored (not even temporarily)

in the vicinity of the boiler.

- Do not allow unsupervised children near the boiler.

Service/inspection of the boiler and the system is

recommended once a year. Maintenance, service

and cleaning are specified in the Installation Instruc-

tions.

Frozen water pipe hazard

Your heating boiler is designed to provide

a warm and comfortable living environment. It is

NOT designed to ensure against freezing of water

pipes. The boiler is equipped with several safety de-

vices that are designed to shut down the boiler and

to prevent it from

restarting in the event of various unsafe

conditions.

If your boiler remains off for an extended period of

time during cold weather, water pipes may freeze

and burst, resulting in extensive water damage and

conditions in which mold could grow. Certain molds

are known to cause respiratory problems, as well as

to pose other serious health risks. In case of water

damage, immediate measures should be taken to dry

out affected areas as quickly as possible to prevent

mold from developing.

If your home will be unattended for anextended pe-

riod of time during cold weather, you should...





 Shut off the water supply to the building, drain

the water pipes and add antifreeze for potable water

to drain traps and toilet tanks. Open faucets where

appropriate.

Or…





 Have someone check the building frequently dur-

ing cold weather and call a qualified service agency

if required.

Or...





 Install a reliable remote temperature sensor that

will notify somebody offreezing conditions within

the home.

Failure to protect against rozen pipesa ety

I you notice ire coming rom the appliance, call the

ire department immediately! Do not attempt to ex-

tinguish the ire unless quali ied to do so.





 Installation area conditions





 Ensure ambient temperatures are higher than

50°F / 10°C and lower than 104°F / 40°C.





 revent the air from becoming contaminated by

homogenate hydrocarbons (e.g. as contained in

paints solvents or cleaning fluids) and excessive

dust (e.g. through grinding or polishing work).

Combustion air for the heating process, and ventila-

tion of the boiler room must be free of corrosive

contaminants. To that end, any boiler must be in-

stalled in an area that has no chemical exposure.

The list to the right indicates the main, currently

known sources.





 Avoid continuously high levels of humidity (e.g.

through frequent drying of laundry).
