WARNING
Installation of boiler should be done only
by qualified expert and in accordance with
appropriate installation manual. Installing
boiler or any other electric appliance with
improper methods or materials may result in
serious injury or death due to fire.

Manual is intended to familiarize installer and user of
Electric Hydronic Block with its installation, operation
and maintenance to assure its normal trouble free
operation.
Argo electric boilers are designed and manufactured
with quality components for maximum life, durability
and minimum service. Follow installation instructions
carefully before operating heating system for
optimum efficiency and satisfaction. Failure to do so
may result in breach of warranty.
producT dEscripTion
Electric Hydronic Block is heating device converts
electrical energy to heat energy through medium
of water. Simplified theory of this conversion is as
follows:
Electrical Energy x Conversion Factor = Energy
– Or –
Kilowatts Of Electricity Used Per Hour x 3412 =
British Thermal Units (Btuh) Available Per Hour For
Heating.
Information is basis used to establish Electric
Hydronic Block ratings (See Table 1 on page 4). Since
conversion process requires no combustion, boiler
operates with highest possible efficiency.
Electric Hydronic Block is constructed with cast
iron boiler that conforms to American Society of
Mechanical Engineers (ASME) Boiler & Pressure
Vessel Code. Interior design allows just enough
water to be present for proper heating element
operation - no excess water is stored which would
cause undesirable thermal losses and longer recovery
times.
Control system is assembled in modular package
keeping overall size and weight of Electric Hydronic
Block to minimum. Construction of entire Electric
Hydronic Block conforms to Canadian Standards
Association (CSA) Standards for Safety for Electric
Boilers.

insTALLATion mAnuAL And opErATing insTrucTions
Argo Electric Boilers are controlled by electronic
control board maintaining water temperature. Control
cycles heating elements based on heating demand,
and preset boiler outlet water temperature. Control
also operates 120Vac circulating pump rated up
to 5A. When thermostat calls for heat, control will
operate boiler to regulate water temperature at pre-
selected set point. System pump is on whenever
thermostat calling for heat.
