Dear Buyer
We wish to congratulate you on the purchase of your TTulpe® gas water heater. It is
safe to say that our gas water heaters will satisfy any of your needs. The use of modern
technologies and high-quality materials in the manufacture of these devices brought
popularity of and confidence in the TTulpe® trade mark.
TTulpe® electric water heaters are designed and manufactured in strict correspondence
with international standards that ensure reliability and safety in operation. The models
were all subjected to compulsory certification by the EU and fully comply with the
requirements of Gas Appliance Directive 2009/142/EC. This Manual covers TTulpe®
models (Series C-Meister). The model name of the water heater you purchased is

Water heater application
This water heater is designed for the purpose of heating potable water.
Its use in an application other than this may shorten its life.
Model type
TTulpe® C-Meister 12
The gas water heater model you have chosen can be installed indoor and is a 12 liters
per minute model. The C-Meister is a modulating constant temperature water heater.
Self-modulating flow sensor technology regulates the amount of energy required to
heat the water needed.
The C-Meister is a direct vent, balanced flue, room sealed gas water heater. This is the
safest type of gas water heaters because the fresh air inlet comes from outside and
the exhaust gasses are pushed outside.
The temperature is controlled by thermostats. Automatic safety controls are fitted to
the water heater to provide safe and efficient operation.
A hardware pack with screws and fittings is included to make the installation easier.
Mains pressure
The water heater is designed to operate at mains pressure by connecting directly to
the mains water supply. The supply pressure should be greater than 0,5 Bar for true
mains pressure operation to be achieved.
How hot should the water be?
The water heater has a minimum temperature setting of 30°C and a maximum thermostat
setting of 60°C .
Hotter water increases the risk of scald injury
This water heater can deliver water at temperatures which can cause scalding.
Check the water temperature before use, such as when entering a shower or filling a
bath or basin, to ensure it is suitable for the application and will not cause scald injury .

Vapors from flammable
liquids will explode and
catch fire causing death
or severe burns.
Do not use or store flam-
mable products such as
gasoline, solvents or ad-
hesives in the same room
or area near the water
heater.
0845CR-0039

Keep flammable products:
1. Far away from heater
2. In approved containers
3. Tightly closed
4. Out of children ‘s reach
Water heater has a main burner flame.
The main burner flame
1. Can come on at any time and
2. Will ignite flammable vapors.
Vapors:
1. Cannot be seen
2. Are heavier than air
3. Go a long way on the floor
4. Can be carried from other rooms to the main burner flame by air currents. Installation:
Read and follow water heater warnings and Instructions. If owners manual is missing,
contact the retailer or manufacturer.
Danger!
Propane/butane and natural gas models
LP or NG has an odorant added to aid in the detecting a gas leak. Some people may
not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar
with the smell of LP/NG, ask the gas supplier. Other conditions such as “odorant fade”,
which causes the odorant to diminish in intensity, can also hide or camouflage a gas
leak.
• Water heatersutilizingLPgasaredifferentfromnaturalgas models. A Natural gas water
heater will not function safely on LP gas and vice versa
• No attempt should ever be made to convert the water heater from LP gas to NG and
vice versa. To avoid possible equipment damage, personal injury, or fire, do not
connect the water heater to a fuel type not in accordance with the data plate.
• LP gas must be used with great caution. It is heavier than air and will collect first in
lower areas making it hard to detect at nose level.
• Before attempting to light the water heater, make sure to look and smell for gas
leaks. Use a soapy solution to check all gas fittings and connections. Bubbling at a
connection indicates a leak that must be corrected. When smelling to detect a gas
leak, be sure to sniff near the floor also.
• Gas detectors are recommended in LP and NG applications and their installation
should be in accordance with the detector manufacturer’s recommendations and/
or local laws, rules, regulations or customs.
1.If the smell of gas is detected, turn off the gas valve at the tank or the main valve in
your gas supply immediately! Do not use flame for leak detection.
2. For Indoor use only

5. Faults
After making the adjustments described above, the water heater is ready to operate
in completely automatic mode. When a hot water tap is opened, an intermittent
discharge is generated on the ignition electrode, which causes lighting of the burner
and, at the same time, operates the gas extraction fan.
All the electronic models have an ionisation electrode inserted in the burner to control
correct flame presence. In case of malfunction or no gas with subsequent burner
shut down, close the hot water tap.
It is then necessary to eliminate the cause or the element preventing the gas from
reaching the water heater, e.g. inadvertent closing of the gas cock, empty gas cylinder,
etc.
Water heater shutdown status is deactivated by closing and opening the hot water
tap. Repeat the operation if the delivery of hot water is not restored after eliminating
the cause and opening the hot water tap. If the fault persists, contact the After-Sales
Technical Service.
