TRIAD Boiler Systems has a manufacturing history of over 80 years. TRIAD patented the original isolated,
modular boiler system concept. Each boiler / burner package has been specifically matched to provide

6 TRIAD Boiler Systems, Inc.
West Chicago, IL

optimal performance. The boilers, however, are only a part of the complete operating system. They can only
meet their ratings if the system is properly designed and if the boilers receive proper care.
Two major things must be focused on to achieve successful implementation: Proper System Design and
Proactive Preventive Maintenance. While the TRIAD Boiler website www.triadboiler.com may address some
issues, a design engineer should be involved. This Operations and Maintenance Manual addresses many
issues regarding usage.
It is important that the system design matches the performance of the boiler. A compatible design that
addresses combustion air, correct system sizing, fuel and water supply, and breeching is crucial, and should
be the responsibility of the system design engineer who must also ensure local code compliance. The boilers
will meet their full potential when part of an appropriate system design.
Efficient burner operation is highly dependent on proper adjustment, adequate combustion air, and correct
breeching. Make sure you carefully read the burner Operating and Maintenance Manual. Incorrectly dealing
with these issues can result in, among other things, a loss of efficiency, higher operating costs, sooting,
frequent cleaning, and high carbon monoxide (CO) output.
The successful, long-term operation of the boiler is dependent on the quality of its water. Failure to provide
suitable water will result in corrosion and the build-up of scale and mud / sludge / sediment causing
inefficient thermal transfer, an associated loss of efficiency, higher operating costs, and eventually lead to
premature boiler failure.
Being cognizant of these issues, and taking proper steps when required, should result in many years of
successful boiler operation.
TRIUMPH SS2 HIGH EFFICIENCY BOILERS
TRIAD is pleased to introduce a new line of High Efficiency boilers, the TRIUMPH SS2 series. This product line
is designed with a large horizontal combustion chamber matched with a specially engineered vertical
condensing section in stainless steel AISI 316 Ti. These elements are immersed in water contained in a
horizontal boiler drum with a vertical column to which the system inlet and outlet connections are fitted. All
the burners, controls, and pumps are all first quality name-brand OEM components.
These boilers reach very high efficiency levels as the flue gases not only are released at a temperature little
higher than that of the system return water, but also a large part of the water vapor contained in the flue
gases is condensed, recovering the latent heat of condensation.
Because the flame path is designed to go through the combustion chamber without inversion, the formation
of Nitrogen Oxides (NOx) is limited as much as possible. This is because NOx typically forms when the flame
remains at high temperature in the combustion chamber for long periods.
The boiler body, is composed of:

7 TRIAD Boiler Systems, Inc.
West Chicago, IL
www.triadboiler.com
Top section which contains a large diameter corrugated 316ti furnace; access is provided by a large
double hinged front door. The burner hinges also open for access.
Large diameter 316ti SS pipes connected directly to the furnace and the front tube plate forming the
second pass.
Corrugated horizontal flue passages of 316ti SS with proprietary surfaces to increase surface area and
heat transfer from the third pass. The corrugated flue passages are inserted into the bottom tubesheet
in an inclined fashion for easy drainage. This section constitutes the third pass and is accessed by a large
double hinged door.
Boiler shell complete with boiler flow, constant temperature return, variable temperature return, fittings
for control thermostats and safety devices.
Rear smoke box also drains the condensate, and a chimney connection drain condensate from the
chimney.
All boiler parts in contact with flue gases are manufactured in stainless steel AISI 316 Ti. The large diameter
and ample furnace volume of these boilers also serve to reduce thermal NOx production.
The TRIUMPH SS2 series boilers place no limit on the return water temperature, and reach the highest
performance when the return temperature is lower than 135°F. At higher temperatures (as with any
condensing boiler) when there is no condensation (water vapor) in the flue gas, latent heat will not not
recovered. The efficiency of Triumph SS2 boilers is very good (90%+) even when it is installed in a traditional
higher-temperature heating system.
The high boiler efficiency is due to optimum combustion efficiency combined with high density 3”
fiberglass insulation the boiler is designed to exceed the requirements of the Department of Energy and is
confirmed by BTS-2000 testing.
READ AND SAVE THESE INSTRUCTIONS FOR REFERENCE. These manual and associated documents are to
be kept with the boiler and in legible condition for the life of the boiler.

Ensure that the hydraulic pressure measured after the reduction valve on the supply pipe does not
exceed the operating pressure specified on the rating plate of the component (boiler, heater etc.).
As the water contained in the heating system increases in pressure during operation,
ensure that its maximum value does not exceed the maximum hydraulic pressure specified
on the component rating plate.
Ensure that the safety valve outlets of the boiler and hot water tank, if any, have been
connected to drain in or-der to prevent the valves from flooding the room if they open.
Ensure that the pipes of the water and heating system are not used as an earth connection
for the electrical system as this can seriously and very rapidly damage the pipes, boiler,
heater and radiators.
Once the heating system has been filled, you are advised to close the supply cock and keep
it closed so that any leaks from the system will be identified by a drop in hydraulic pressure
indicated on the system pressure gauge.
IMPORTANT!
IF THE BOILER IS NOT SUPPLIED WITH ACID CONDENSATE NEUTRALIZER, A SIPHON MUST BE
FITTED ON THE CONDENSATE DRAIN IN ORDER TO AVOID FLUE GAS LEAKAGE.
NOTE: IF ONLY ONE RETURN IS REQUIRED, ALWAYS USE THE LOW TEMPERATURE ONE (CLOSEST
TO FLOOR)
2.1.2 Insulation of the Boiler Body
The boiler is supplied fixed to a wooden supporting base (1) to allow handling and to facilitate the
insulation process. The glass wool insulation, consisting of 3 layers, is fitted at the factory and
wrapped on the parts shown in the figure and fixed to the connection sides by clamps
