HTP EFT-80 Installation, Start-Up, Maintenance, Parts, Warranty

LP-387 Rev. 7.3.15
6
Altering any HTP, Inc. boiler with parts not manufactured by
HTP, Inc. WILL INSTANTLY VOID the boiler warranty and could
result in property damage, personal injury, or death.
Do not use this boiler for anything other than its intended
purpose (as described in this manual). Doing so could result in
property damage and WILL VOID product warranty.
High heat sources (sources generating heat 100
o
F / 37
o
C or
greater, such as stove pipes, space heaters, etc.) may damage
plastic components of the boiler as well as plastic vent pipe
materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8” from high
heat sources. Observe heat source manufacturer instructions,
as well as local, state, provincial, and national codes, laws,
regulations and ordinances when installing this boiler and
related components near high heat sources.
A. Improper Combustion
Do not obstruct the ow of combustion and ventilating air.
Adequate air is necessary for safe operation. Failure to keep the
exhaust vent and combustion air intake clear of ice, snow, or
other debris could result in property damage, serious personal
injury, or death.
B. Gas
Should overheating or gas supply fail to shut o, turn o the
manual gas control valve to the boiler.
C. When Servicing the Boiler
To avoid electric shock, disconnect electrical supply before
performing maintenance.
NOTE: When inquiring about service or troubleshooting,
reference the model and serial numbers from the boiler rating
label.
Be sure to disconnect electrical power before opening boiler
cabinet or performing service. Failure to do so could result in
electrical shock, property damage, serious personal injury, or
death.
D. Boiler Water
• If you have an old system with cast iron radiators,
thoroughly ush the system (without boiler connected)
to remove sediment. The high-eciency heat
exchanger can be damaged by build-up or corrosion
due to sediment. HTP recommends a suction strainer
in this type of system.
• Do not use petroleum-based cleaning or sealing
compounds in boiler system. Gaskets and seals in
the system may be damaged, possibly resulting in
substantial property damage.
• Do not use “homemade cures” or “boiler patent
medicines”. Substantial property damage, damage to
boiler, and/or serious personal injury may result.
• Continual fresh make-up water will reduce boiler life.
Mineral buildup in the heat exchanger reduces heat
transfer, overheats the stainless steel heat exchanger,
and causes failure. Addition of oxygen from make-
up water can cause internal corrosion in system
components. Leaks in the boiler or piping must be
repaired at once.
NOTE: DO NOT add cold make up water to the system when
the boiler is hot. Thermal shock can potentially cause cracks
in the heat exchanger. Such damage IS NOT covered by
warranty.
E. Freeze Protection
NOTE: Consider piping and installation when determining
boiler location.
Due to the low water content of the boiler, improper sizing of the
boiler with regard to heating system load will result in excessive
cycling and accelerated component failure. HTP DOES NOT
warrant failures caused by improperly sized boiler applications.
DO NOT oversize the boiler to the system. Modular boiler
installations greatly reduce the likelihood of boiler oversizing.
NEVER use any toxic chemical, including automotive,
standard glycol antifreeze, or ethylene glycol made for
hydronic (non-potable) systems. These chemicals can
attack gaskets and seals in water systems, are poisonous if
consumed, and can cause personal injury or death.
UNCRATING THE BOILER - Any claims for damage or
shortage in shipment must be led immediately against the
transportation company by the consignee.
Failure of the boiler due to freeze related damage IS NOT
covered by product warranty.
Part 2 - Before You Start
Components (and Part #) included with the boiler:
• Temperature and Pressure Gauge (7500P-098)
• Pressure Relief Valve (EFT-55/80/110/155/199 - 7250P-
080, EFT-285/399 - 7350P-066)
• Wall Mount Bracket (EFT-55/80/110 - 7600P-021, EFT-
155/199/285 - 7600P-121, EFT-399 - 7600P-221)
• Indirect Sensor (7250p-325)
• Outdoor Sensor (7250P-319)
A. What’s in the Box
Remove all sides of the shipping crate of the boiler.
DO NOT USE THIS BOILER IF ANY PART HAS BEEN
SUBMERGED IN WATER. Immediately call a qualied
service technician. The boiler MUST BE replaced if it has been
submerged. Attempting to operate a boiler that has been
submerged could create numerous harmful conditions, such as
a potential gas leakage causing a re and/or explosion, or the
release of mold, bacteria, or other harmful particulates into
the air. Operating a previously submerged boiler could result in
property damage, severe personal injury, or death.
NOTE: Boiler damage due to ood or submersion is considered
an Act of God, and IS NOT covered under product warranty.
To avoid severe burns, allow boiler and associated equipment
to cool before servicing.
