injury or property damage. Improper installation, adjustment, alteration, service and use of this unit
can result in serious injury.
This unit must be installed by a licensed electrician and plumber. The installation must comply with
all national, state and local plumbing and electric codes. Proper installation is the responsibility of the
installer. Failure to comply with the installation and operating instructions or improper use voids the
warranty.
Save these instructions for future reference. Installer should leave these instructions with the consum-
er.
If you have any questions regarding the installation, use or operation of this micro boiler, or if you
need any additional installation manuals call Stiebel Eltron at 800.805.5384 or visit us online at www.
hydro-shark.com
• The output of heat from the boiler is electronically controlled. The boiler will deliver any water tem-
perature between 86° F - 140° F. Set the desired water delivery temperature using the knob on the
front cover. (Do not exceed temperatures above 130° when using this product with tubing in
concrete)
• When the power light is flashing, full element power is being applied. When the power light is not
flashing, the element power is being modulated to the water delivery temperature.
• Recommend setting for radiant floor heating (Tubing in Concrete) is 105° F - 125° F.
• Recommended setting for Staple Up (Floor Warming Only) is 130° - 140° F.
• Temperature setting and water delivery temperatures may vary depending on flow rates. Size boil-
er accordingly. See flow rate chart for more information.

MOUNTING THE UNIT
UNIT MUST BE INSTALLED IN A VERTICAL POSITION WITH THE WA-
TER FITTINGS POINTING DOWNWARD. DO NOT INSTALL UNIT WHERE
IT WOULD ROUTINELY BE SPLASHED WITH WATER OR ELECTRICAL
SHOCK MAY RESULT.
1. Leave a minimum of 5” clearance on all sides for servicing.
2. Make sure the power is off.

ELECTRICAL CONNECTIONS
1. All electrical work must comply with the national, state, local & any other applicable codes.
2. The boiler should be connected to properly grounded dedicated branch circuits of proper
voltage rating. Ground must be brought to the ‘Ground’ at the circuit breaker panel.
3. HydroShark 12 can be connected to ONE independent circuit.
4. AHydroShark 14, HydroShark 19 & HydroShark 24 can be connected to TWO independent
circuits Use supply table. Protected by TWO double pole breakers sized for the load.
5. AHydroShark 29 and HydroShark 36, can be connected to THREE independent circuits.
Use supply cable protected by THREE double pole breakers sized for the load.
6. Cut the electrical connection cable to length and strip.
7. The wire must be fed through the knockouts located between the Supply and Return fluid con-
nections. The “Live” wires must be connected to the slots on the terminal block marked “L” and
“L”. The ground wire must be connected to slot marked with the ground symbol.
8. Reinstall the cover screws.
WARNING! As with any electrical appliance, failure to electrically ground may result in serious injury or Death.
WARNING: BEFORE BEGINNINGANY WORK ON THE ELECTRIC INSTAL-
LATION, BE SURE THAT THE MAIN BREAKER PANEL SWITCHES ARE
“OFF” TO AVOID ANY DANGER OF ELECTRIC SHOCK. ALL MOUNTING
AND PLUMBING MUST BE COMPLETED BEFORE PROCEEDING WITH
ELECTRICAL HOOK-UP. WHERE REQUIRED BY LOCAL,STATE OR NA-
TIONAL ELECTRICAL CODES THE CIRCUITS SHOULD BE EQUIPPED
WITH A “ GROUND FAULT INTERRUPTER”.

NOTE: EXCESSIVE HEAT FROM SOLDERING COPPER PIPES NEAR THE BOILER MAY CAUSE DAMAGE.
1. All plumbing work must comply with the national, state, local & any other applicable codes.
2. Make sure the radiant floor system has been purged & is free of floating debris.
3. The return side (inlet) is on the right side of the unit, the supply side (outlet) is on the left of
the unit.
4. A pressure & temperature relief valve should be installed on the hot water supply side (out-
let) of the unit. (Stiebel Eltron Pre-Plumbed Panels include pressure relief valve)
5. The boiler is designed for a connection to copper tubing and/or PEX tubing. If soldering the unit
is necessary, please direct the flame away from the housing of the unit to avoid damage.
6. When all plumbing work is completed, check for leaks & take corrective action before pro-
ceeding.

APPLICATIONSSpace Heating Applications
• In order to purge air in water pipes within a closed loop system, an air vent,
air separator, and expansion tank should be installed in the system. (Stiebel
Eltron pre-built space heating panels incorporate all of these features).
• Water temperature over 125° F (52° C) can cause sever burns instantly of
death from scalding.
• Chemicals such as diluted Glycol can be used for radiant floor, Hydro/fan
coil air or Baseboard heating only. The diluted solution of glycol must contain
between 25% and 55% of Glycol. Be aware that in a closed loop system, low
pressure in the heat exchanger can cause low-temperature boiling, resulting
in excessive noise and damage to the micro boiler. Consult with the glycol
maker for specifications prior to use.
Stiebel Eltron Pre-Built Space Heating Panels
Stiebel Eltron pre-plumbed panels help make space heating easy and reliable. These panels are
professionally engineered and use proven Primary/Secondary hydronic practices. Call Tech Support
(1-800.805.5384) for assistance.
