1 Warning

For your safety

Do not store or use gasoline or other flammable,

combustible or corrosive vapors and liquids in the

vicinity of this or any other appliance.

Warning: Carefully plan where to

install the heater. Correct combustion

air supply and flue pipe installation are

very important. If a gas appliance is not

installed correctly, fatal accidents can

result such as carbon monoxide

poisoning or fire.

Warning: Exhaust gas must be vented

to outside using approved vent material

See table 2, page 11 (For Canada use

only PVC ULC S636). Vent and

combustion air connector piping must

be sealed gas-tight to prevent

possibility of flue gas spillage, carbon

monoxide emissions and risk of fire,

resulting in severe personal injury or

death. Approved vent terminators must

be used when penetrating to the

outside.

Warning: Field wiring connections and

electrical grounding must comply with

local codes, or in the absence of local

codes, with the latest edition of the

National Electric Code, ANSI/NFPA 70,

or in Canada, all electrical wiring must

comply with the local codes and the

Canadian Electrical Code, CSA C22.1

Part 1.

Warning: Shock hazard: line voltage is

present. Before servicing the water

heater, unplug power supply cord from

outlet. Failure to do so could result in

severe personal injury or death.

Warning: The heater must be

disconnected from the gas supply

piping system during any pressure

testing of that system at test pressures

equal to or more than 0.5 psig.

Warning: The appliance should be

located in an area where water leakage

of the heat exchanger, piping or

connections will not result in damage to

the area adjacent to the appliance or to

lower floors of the structure. When such

locations cannot be avoided, it is

recommended that a suitable drain pan,

adequately drained, be installed under

the appliance. The pan must not restrict

combustion air flow.

Warning: The maximum inlet gas

pressure must not exceed the value

specified by the manufacturer and the

minimum value listed is for the purpose

of input adjustment.

Warning: If a water heater is installed in

a closed water supply system, such as

one having a backflow preventer in the

cold water supply line, means shall be

provided to control thermal expansion.

Contact the water supplier or local

plumbing inspector on how to control

this situation.

Warning:

B Every time there is a demand for hot

water the tankless must recognize the

activation flow, activate the burners, and

raise the temperature to the set point

temperature.

B The time to reach set temperature

depends upon the inlet temperature, the

distance to the tap and the water flow.

B Usage patterns with short duration

draws may not give the tankless the time

to reach the desired temperature.

Examples are commercial kitchen

sprayers and some dishwashers with

short cycles.

B In such applications a small buffer tank

may be needed to improve performance.

Contact Bosch Water Heating for

additional information.

Warning: Keep the appliance area

clear of combustible materials, gasoline

and other flammable vapors and liquids.
