HIGH-ALTITUDE INSTALLATIONS
Check the elevation where your micro boiler is installed. Set DIPswitches shown in the table
below depending on the altitude.
• Improper venting of this appliance can result in excessive levels of carbon
monoxide which can result in severe personal injury or death.
DANGER
CAUTION
This appliance must be vented in accordance with the section” Venting of Equipment” of the current
edition of the National Fuel Gas Code: ANSI Z223.1/NFPA 54 in the United States and/or Section 8 of
the B149.1 Natural Gas and Propane Installation Code in Canada, as well as applicable local building
codes. The manufacturer recommends NovaVENT or Z-Vent Category III, single wall, stainless steel
venting.
The boiler can obtain its combustion air from the space that it is installed in or it can be direct vented
using the direct vent conversion kit (TK-TV10). Ensure the location has suffi cient, clean combustion
air.
General rules for venting micro boilers are:
• Improper installation can cause nausea or asphyxiation, severe injury or death
from carbon monoxide and fl ue gases poisoning. Improper installation will
void product warranty.
When installing the vent system, all applicable national and local codes must be
followed. If you install thimbles, fi re stops or other protective devices and they
penetrate any combustible or noncombustible construction, be sure to follow all
applicable national and local codes.
• Place the micro boiler as close as possible to the vent termination.
• The vent collar of the micro boiler must be fastened directly to an unobstructed vent pipe.
• Do not weld the vent pipe to the micro boiler’s vent collar.
• Do not cut the vent collar of the unit.
• The vent must be easily removable from the top of the boiler for normal service and inspection of
the unit.
• The micro boiler vent must not be connected to any other gas appliance or vent stack except an
approved common venting system.
• Avoid using an oversized vent pope or using extremely long runs of the pope unless it is part of an
approved common vent system.
• For rooftop venting, a rain cap or other from of termination that prevents rain water from entering
into the micro boiler must be installed.
• Do not terminate vent into chimney. If the vent must go through the chimney, the vent must run all
the way through the chimney with approved vent pipe.
General rules for vent terminations:
• Avoid locating the micro boiler vent termination near any air intake devices. These fans can pick
up the exhaust fl ue products from the micro boiler and return them to the building. This can create
a health hazard.
• Locate the vent termination so that it cannot be blocked by any debris, at any time. Most codes require that the termination be at least 12 in. (305 mm) above grade, but the installer may determine
if it should be higher depending on the job site condition and applicable codes.
• A proper sidewall termination is recommended when the micro boiler is vented through a sidewall.
• Be sure to check the clearance form the exhaust termination to the air inlet or opening in the vent
termination clearances section.

Pressure relief valve
The micro boiler has a high-temperature shutoff switch built in as a standard safety feature (called a
Hi-Limit switch) therefore a “pressure only” relief valve is required.
• This unit does not come with an approved pressure relief valve.
• An approved pressure relief valve must be installed on the hot water outlet.
• The pressure relieve vale must conform to ANSI Z21.22 or Can 1-4.4 and installation must follow
local codes.
• The discharge capacity must be at least 140,000 BTU/h.
• The pressure relief valve needs to be rated for a maximum of 150 psi (1 MPa).
• The discharge piping for the pressure relief valve must be directed so that the hot water cannot
splash on anyone or on nearby equipment.
• Attach the discharge tube to the pressure relief valve and run the end of the tube to within 6
in.(152 mm) from the fl oor. This discharge tube must allow free and complete drainage without any
restrictions.
• If the pressure relive valve installed on the micro boiler discharges periodically, this may be due to
a defective thermal expansion tank or defective pressure relief valve.
• The pressure relief valve must be manually operated periodically to check for correct operation.
• No valve must be placed between the relief valve and the micro boiler.
WARNING
ELECTRICAL CONNECTIONS
• Follow the electrical code requirements of the local authority having jurisdiction. In the absence of such requirements, follow the current edition of the National Electrical Code ANSI/NFPA 70 in the U.S. or the current edition of CSA

APPLICATIONS
Space 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. (Hydro-
Shark pre-built space heating panels incorporate all of these features).
WARNING
HydroShark per-plumbed panels help make space heating easy and reliable. These panels are professionally engineered and use proven Primary/Secondary hydronic practices. Call Tech Support
(800.805.5384) for assistance.
• 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 fl oor, 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 specifi cations prior to use.

FLOW
• The fl ow rate through the micro boiler is limited to a maximum of 6.6 GPM (38 L/min).
• The temperature setting, along with the supply temperature of the water will determine the fl ow
rate output of the unit.
FREEZE PROTECTION SYSTEM
• This unit comes equipped with heating blocks to protect it against damages associated with freezing.
• For this freeze protection system to operate, there has to be electrical power to the unit. Damage
to the heat exchanger caused by freezing temperates due to a power loss is not covered under
warranty. In cases where power losses can occur, consider the use of a backup power supply.
• The freeze protection system will activate when the surrounding and/or outside temperature drop
below 36.5°F (2.5° C).
• It is the installer’s responsibility to be aware of freezing issues and take all preventive measures.
The manufacture will not be responsible for any damage to the heat exchanger as a result of
freezing.
• In any area subject to freezing temperatures, freezing issues can occur if cold air enters through
the venting into the heat exchanger by either negative pressures within the installation location or
by strong outside wind. The manufacturer highly recommends the use of a back fl ow preventer
(sold separately) to minimize the amount of cold air entering through the exhaust venting when the
micro boiler is off .
• It is the installer’s responsibility to be aware of freezing issues and take all preventive measures.
The manufacture will not be responsible for any damage to the heat exchanger as a result of
freezing.
• If you will not be using your boiler for a long period of time:
1. Completely drain the water out of the unit.
2. Disconnect power to your boiler.
This will keep your unit from freezing and being damaged.
Only pipes within the micro boiler are protected by the freeze protection system.
Any water pipes (hot or cold) located outside the unit will no be protected. Properly
CAUTION
WWW.HYDRO-SHARK.COM HYDROSHARK 115| 31
protect and insulate these pipes from freezing.
