CFH, Indoor/Outdoor
Models 1000, 1500, 2000, 3000
Contractor shall supply and install Qty.: Laars Model No. CFH modulating condensing boiler(s).
The boiler shall be a Laars MagnaTherm FT Model CFH , rated at BTU/hr input and BTU/hr output. The
boiler shall modulate up to 5-100% of full re, for up to 20:1 turndown. The unit(s) shall be design-certied 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 160 psi (1103 kPa) maximum working pressure, shall bear
the ASME "H" Stamp and be listed by the National Board.
The boiler shall be listed with AHRI (Air Conditioning, Heating and Refrigeration Institute). The boiler shall have minimum thermal e󰀩ciency of 95%.
The unit(s) shall be constructed to comply with the e󰀩ciency requirements of the latest edition of ASHRAE Standard 90.1.
The boiler shall be sealed combustion, and shall use a vertically-oriented 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. The gas/
air system shall allow the boiler to modulate and remain stable throughout the ring range. An oxygen trim system shall be standard equipment, and
shall constantly measure the oxygen in the exhaust gases, and adjust the air/fuel ratio by varying the combustion air speed, relative to the fuel valve
settings, to ensure consistent e󰀩ciency, clean combustion, and high heat recovery throughout the modulation range.
The boiler shall operate at natural gas pressures of 4-10.5" w.c., and shall need no component changes to operate at high altitude, up to 10,000 feet.
The boiler shall be certied for placement indoors and outdoors.
The boiler shall be designed and certied for vertical or horizontal Category IV venting, up to 100 equivalent feet, with 6" (1000), 8" (1500-2000), or 10”
(3000) diameter CPVC, polypropylene or stainless steel vent material. The boiler shall be certied for Category II venting with vent pressures of -0.1 to
-.001" w.c.. Air may be taken from the room, or ducted directly to the boiler using up to 100 equivalent feet of 6" (1000), 8" (1500-2000), or 10” (3000)
diameter ABS, PVC, CPVC or galvanized pipe. The boiler shall have an integral, washable, combustion air lter with 83% arrestance.
The heat exchanger shall be a stainless steel re tube design. It shall be a vertical design with a single pass for ue gas. 316L stainless steel shall be
used for the tubes, tube sheets, combustion chamber, ue collector, and condensate dish. All other wetted surfaces shall be 304L stainless steel. The
boiler shall be fully condensing design with built-in condensate drain and trap that includes automatic boiler shuto󰀨 if condensate levels are too high,
due to blockage. The heat exchanger shall have a limited non-prorated ten-year warranty, and a limited twenty-ve-year thermal shock warranty.
The boiler shall be equipped with an ASME certied pressure relief valve set at 75psi 517 (kPa). Optional pressure relief valves with settings of 30psi
(207kPa), 50psi (345 kPa), 60psi (413 kPa), 125psi (861 kPa), or 150psi (1034 kPa) shall be available. The boiler shall have a factory-mounted
temperature and pressure relief gauge.
The boiler jacket shall be made from a combination of stainless steel and galvanealed steel panels. Galvanealed steel panels shall have 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. To assist in boiler installation, the heat exchanger shall have two welded lifting lugs,
and the structural steel based shall have forklift openings.
The boiler shall be available with the following voltages:
Models 1000 and 1500: 120V, 208V, or 220/240V single phase
Model 2000: 120V single phase, 208V single phase, 220/240V single phase, 208V three phase, 480V three phase, or 600V three phase
Model 3000: 208V, 480V, or 600V three phase
The boiler shall have an integrated temperature / ignition control, oxygen trim control, and valve control that work together to ensure boiler operation,
safety and combustion functions are harmonized. The boiler shall have a spark ignitor and ame sensor that is controlled to have 100% safety
shutdown, and three trials for ignition (CSD-1 models have one trial).
The temperature / ignition control shall be an integrated electronic PID control with large touchscreen and color display. The boiler display shall be
visible without the removal of any jacket panels or control panels. The control shall display using icons and words, for clarity. The control's home
page shall display security level, quick start access, conguration menu access, service menu access, messages, an indication of which demands are
active, a navigation bar, date, and time. In addition, the home screen shall display all set points, actual and target ring rates, outside air temperature,
ame signal, O
2
reading, ue temperature, boiler inlet and outlet temperatures, system temperature (when system sensor is used), domestic water
temperature (when DHW sensor is used), and status of all pumps.
The control shall have a quick-start menu, conguration menu, and service menu. The quick start menu shall allow conguration of basic functionality
and the most common settings, without the need to access all parameters that are available. The conguration menu shall hold all settable/changeable
parameters. The service menu shall allow for access to information that will help setup and troubleshoot the boiler.
The control shall have three levels of access, each with a unique password; user, installer and OEM. A verication feature shall be present, to ensure
that safety-related parameters are not altered by mistake. The control shall have a lockout feature, so that changes cannot be made without entering
the password. The user shall be able to choose how long the control will remain unlocked after user interaction has stopped.
The control shall have two independent space heating setpoints and an indirect domestic water (DHW) setpoint, each with adjustable di󰀨erentials. The
boiler shall come equipped with a DHW sensor, but the control shall be able to recognize a call for DHW via this sensor or a closure from a tank stat
on the same terminals. The user shall be able to choose the priority of all demands. It shall have the ability to control the boiler pump, system pump
and indirect domestic water pump, each with delay and exercise features. The control shall have a variable speed boiler pump control as standard, to
control the pump to maintain a user-selectable xed temperature rise across the boiler.
The boiler shall have the ability to control an isolation valve (available from the manufacturer) that will allow water ow through the boiler only when the
boiler is ring, enabling easy integration into single pump piping systems.
The control shall have built-in outdoor reset feature with warm weather shutdown, DHW override, and customizable reset curves, based on the outdoor
