Contractor shall supply and install Qty.: Laars Model No. NTH modulating, pump-mounted boiler(s).
The boiler shall be a Laars NeoTherm Model NTH , rated at the input and output shown on the schedule. The boiler shall
modulate 20-100% of full re. The unit(s) shall be design-certied to comply with the current edition of the Harmonized ANSI Z21.13 / CSA 4.9
Standard for Gas- Fired Low Pressure Steam and Hot Water Boilers. The unit(s) shall be designed and constructed in accordance with the ASME
Boiler & Pressure Vessel Code, Section IV requirements for maximum working pressure of 30 psi (207 kPa) (models 80-210) or 160 psi (1103 kPa)
(model 285), and shall bear the ASME "H" Stamp and be listed by the National Board. The unit(s) shall be constructed to comply with the eciency
requirements of the latest edition of ASHRAE Standard 90.1. The boiler shall be equipped with an ASME certied pressure relief valve set at 30psi
(207kPa) (models 80-210) or 75 psi (517 kPa) (model 285).
The boiler shall be listed with the U.S. Department of Energy as an Energy Star appliance. The boiler shall be listed with AHRI (Air Conditioning,
Heating and Refrigeration Institute). The boiler shall have a minimum AFUE of 95%.
The water tube heat exchanger shall be stainless steel. The heat exchanger shall be a low water volume design, welded construction, with no
gaskets, o-rings or bolts in the header. Heat exchanger shall be accessible for visual inspection and cleaning of all internal surfaces. The boiler
shall be fully condensing design with built-in condensate drain and trap. The heat exchanger shall have a limited twelve-year warranty.
Each boiler shall be fully test red, (with water, gas, and venting connected), and all safety components tested, at the factory.
The boiler shall be sealed combustion, and removal of jacket panels shall not aect the combustion seal. The boiler jacket shall be a unitized shell
nished with acrylic thermo-set paint baked at not less than 325°F (163°C). The frame shall be constructed of galvanized steel for strength and
protection. Chamber shall include a sight glass for viewing ame. Boiler shall be certied for zero clearance to combustible surfaces.
All water, gas, vent and air connections shall be on the top of the boiler, and the top jacket panels shall be split, such that they are removable
without disconnecting the water, gas, vent or air pipes.
The boiler shall be shipped with a pump and a conduit. The wiring and terminals shall be wired to the pump. The boiler shall have a anged inlet
water connection that allows the pump to be connected directly to the top of the boiler in the eld. The pump shall be capable of serving the boiler's
heat exchanger and 30 feet of piping that is the same size as the boiler's water connections, with a normal number of pipe ttings.
Boiler shall operate on 4-13" w.c. gas pressure, and shall need no component changes to operate at high altitude, up to 10,000 feet.
The boiler shall use a premix burner with a stainless steel woven metal ber wrap, and a negative pressure gas valve to burn cleanly, with NOx
emissions not exceeding 10ppm. The boiler shall meet the emissions requirements of SCAQMD 2012.
The boiler shall be designed for vertical or horizontal Category IV venting:
• Models 80-105: Up to 40 equivalent feet with 2" diameter PVC, CPVC or stainless steel vent material, or up to 100 equivalent feet, with 3"
diameter PVC, CPVC or stainless steel vent material.
• Models 150-210: Up to 100 equivalent feet with 3" diameter PVC, CPVC or stainless steel vent material.
• Model 285: Up to 100 equivalent feet with 4" diameter PVC, CPVC or stainless steel vent material.
Air may be taken from the room, or ducted directly to the boiler:
• Models 80-105: Up to 40 equivalent feet with 2" diameter ABS, PVC, CPVC or galvanized pipe or up to 100 equivalent feet of 3" diameter
ABS, PVC, CPVC or galvanized pipe.
• Models 150-210: Up to 100 equivalent feet of 3" diameter ABS, PVC, CPVC or galvanized pipe.
• Model 285: Up to 100 equivalent feet of 4" diameter ABS, PVC, CPVC or galvanized pipe.
The boiler shall be shipped with PVC sidewall vent and air terminals, for use with horizontal systems. The rst section of CPVC vent pipe shall be
shipped with each boiler.
Unit shall be 120VAC, single phase, less than 6 Amps (including mounted pump) for connection to a 15A breaker. The control circuit shall be 24VAC.
The boiler control shall be an integrated electronic PID temperature and ignition control with LCD and touchpad and shall control the boiler
operation and ring rate. The control shall have three menu structures for user mode, set-up mode, and diagnostic model. The boiler display shall
be visible without the removal of any jacket panels or control panels.
When a display or control is eld-replaced, the device shall have the ability to read parameter setpoints from the original set-up, so the system does
not have to be re-programmed.
