NTI Trinity Fire Tube Condensing Combi Boilers

The NTI Trinity Fire Tube is NTI's latest high efficiency condensing boiler or combi boiler. With a 90.0%† AFUE efficiency rating, stainless steel design, nine models from 60,000 to 399,000 Btu/h (17.6 to 116.9 kW), multiple venting options (2" venting and up to 150' runs) and a user-friendly ifLEX touchscreen interface, the Fire Tube offers the ultimate combination of efficiency, quality, flexibility and innovation.

Innovations:

• 

  NTI Fire Tube Combustor

  Down-fired Fire Tube (Tft): The Tft heat exchanger is ASME certified and uses an innovative down-fire combustor. The combustion tubes also have a dimpled design to optimize heat transfer and increases energy efficiency. The Fire Tube provide generous space for flue gas to pass and significantly reduce the need for cleaning due to the vertical configuration and self-cleaning operation when in condensation mode.
  
  
• Stainless steel design: The wet leg combustion chamber enables up to 99% combustion efficiency. The ASME certified heat exchanger is constructed using type 439 stainless steel, making it extremely resistant to corrosion. The Fire Tube design allows water to flow freely around the heating surfaces of the boiler, which significantly reduces pressure drop.
  
  
• Efficiencies and Performance: The Tft provides AFUE efficiencies up to 90.0%†. NTI was first to develop the totally sealed combustion system, whereby air is not drawn from the surrounding cabinet space.
  
  
• Flexibility: The design of the Tft offers more flexibility than any other boiler on the market, with vent runs up to 150' (45 m), five vent termination options, 2" venting on some models with plumbing and gas connections on top or bottom of the unit.
  
  
• ifLEX Interface: Provides easy navigation to all of the controllers parameters and set points. The backlit screen continuously displays system information to ensure safe and efficient operation.
  
  
• ifLEX Touchscreen: The optional 5.7" colour touchscreen provides easy programming, control and quick setup with user-friendly screen displays and options.

Additional Features:

• Certified internal low water cut-off with test button.
• Fully-modulating combustion system with up to 5:1 turndown.
• Condensate pump receptacle.
• Wall-mount configuration with optional floor stand.
• High-energy spark ignition (with external spark generator).
• 15 year heat exchanger limited warranty.

Controller Features:

• Ultimate controllability with advanced Sola Controller.

• Contacts for external limits and alarms.
• Compatible with domestic hot water tank sensor.

NTI Trinity Lx Boilers or Water Heaters

The NTI Trinity Lx boiler series provide luxury features and quality with superior efficiencies. They are also the only certified boilers can be used as either a boiler or a potable instantaneous hot water heater for commercial applications. With nine sizes to choose from 150,000 to 800,000 Btu/h (44.0 to234.5 kW) the NTI Trinity Lx series boilers will provide for all of your larger requirements.

Features at a glance:

• Colour 5.7" touchscreen display with advanced but easy to use menus.
• Patented 316L stainless heat exchanger with efficiencies of up to 98% steady state and 90.0%† AFUE.
• Industry leading modulation rates.
• High-quality construction with clear coat finish.
• Both vents conveniently located on top of cabinet.
• Alarm contacts.
• Innovative floor or wall-mount configuration provides exceptional access to all components.
• Factory-installed condensate trap with no moving parts.
• Spark ignition with dual electrodes using a high-output transformer for successful ignitions every time.
• Removable door and hinged display panel for ultimate access and serviceability.
• No clearance required on the back, bottom or right side.
• Three configuration pump outputs.
• When used as a instantaneous water heater‡ the Trinity Lx provides a tremendous amount of endless hot water with one of the best recovery rates in the industry.

‡Additional equipment is required such as a storage tank, aquastat, bronze pump and flow switch.

NTI Trinity Ti Boilers or Water Heaters

The NTI Trinity Ti 150 and NTI Trinity Ti 200 combi boilers provide both space heating and domestic hot water in one ultra-compact, high-efficiency gas boiler. The Trinity's electronic modulation combustion system electronically increases or decreases the flame size depending on flow and water temperature. As the water is instantaneously heated and regulated, a storage tank is not required and energy is not lost due to typical tank stand-by losses. As well, the Trinity Ti is a totally sealed combustion system, meaning that all combustion air is drawn from the outside then expelled. This eliminates any need for fresh air intake into the room, thereby increasing efficiency.

Features at a glance:

• Energy efficiency of up to 90.0%† AFUE.
  

  NTI Trinity Combustor

• High capacity heat exchanger coil provides ample hot water for all household needs at low cost.
• Distinctive case design reduces costly standby losses and eliminates combustion noises.
• Designed to withstand power dips and spikes.
• Multifunction LED Display.
• Superior mounting configurations allow both wall and floor mounting.
• Outdoor sensor for automatic boiler temperature reset.
• Pump exerciser activates for 5 seconds every 72 hours to prevent seizing.
• Certified, designed, and rated to strict CSA, AGA, ASME, and CSA codes.

†The AFUE ratings have been reduced to 90.0% pending AHRI's determination whether corrected testing procedures are necessary. For more information please see AHRI's press release.
