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.
To avoid severe burns, allow boiler and associated equipment to cool
before servicing.
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
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.
Failure of the boiler due to freeze related damage IS NOT covered
by product warranty.

A. What’s in the Box
B. How the Boiler Operates
Elite FT® condensing technology intelligently delivers hydronic
heating while maximizing eciency. Outlined below are the features
of the system and how they operate:
Stainless Steel Heat Exchanger
The highly ecient stainless steel heat exchanger is designed to
extract all available heat from the supply line before it is exhausted.
Modulating Combustion System
The combustion system modulates the output of the burner during
operation to match system demand and achieve the control set
point while in operation. The set point can change by internal or
external signals to enhance the overall performance of the system.
Control
The integrated control system monitors the system and regulates
fan speed to control boiler output. This allows the boiler to deliver
only the amount of heat energy required and nothing more.
UNCRATING THE BOILER - Any claims for damage or shortage in
shipment must be led immediately against the transportation
company by the consignee.
Part 2 - Before You Start
Remove all sides of the shipping crate of the boiler.
F. High Elevation Installations
Natural gas at high elevation might contain less heating value
than typical 1,000 BTU/cu ft and therefore can cause improper
air / gas mix leading to improper combustion. For natural gas
installations above 3,000 ft, call your gas provider to determine
the heating value of the supplied natural gas.
exchanger. Such damage IS NOT covered by warranty.
