Installation Instructions

8
• Installation and service must be performed by a qualied installer (for
example, a licensed plumber or gas tter, otherwise the warranty will be
void.
• The installer (licensed professional) is responsible for the correct instal-
lation for the micro boiler and for compliance with all national, state /
provincial, and local codes.
• The manufacturer does not recommend installing the micro boiler in a
pit or location where gas and water can accumulate.
• Do not have the vent terminal pointing toward any operating window, door, or
opening into a building.
• Do not install next to any source of airborne debris, such as clothes dryer, that
can cause debris to be trapped inside the combustion chamber, unless the
system is direct vented.
• The manufacturer does not recommend installing the micro boiler in an
attic due to safety issues. If you install the micro boiler in an attic:
-Make sure the unit will have enough combustion air and proper ventilation.
-Keep the area around the micro boiler clean. When dust collects on the
ame sensor, the micro boiler will shut down on an error code.
-Place the unit for easy access for service and maintenance.
-A drain pan, or other means of protection against water damage, is to be
installed under the micro boiler in case of leaks.
• The warranty will not cover damage cause by water quality.
-Only distilled water or distilled water/glycol mixtures can be used with this
micro boiler, unless when used in-conjunction with Hydro-Smart Combi panel
system. Do not introduce pool or spa water, or any chemically treated water into
the micro boiler.
-Water hardness levels must not exceed 7 grains per gallon (120 ppm) for
single family applications or more than 4 grains per gallon (70 ppm) for all other
types of applications/ Water hardness leads to scale formation and may affect
/ damage the micro boiler. Hard water scaling must be avoided or controlled by
proper water treatment.
-Water pH levels must be between 6.5 and 8.5.
-Well water must be treated.
• Do no install the micro boiler where water, debris, or ammable vapors may
get into the ue terminal.
• Although the micro boiler is designed to operate with minimal sound, the
manufacturer does not recommend installing the unit on a wall adjacent
to a bedroom, or a room that is intended for quiet study or meditation,
etc.
• Locate your boiler close to a drain where water leakage will not do damage to
surrounding areas. As with any water heating appliance, the potential for leak-
age at some time in the life of the product does exist. The manufacturer will
not be responsible for any water damage that may occur. If you install a drain
pan under the unit, ensure that it will not restrict the combustion air ow.
