Dunkirk Condensing Gas Boilers
Dunkirk Condensing Gas Boilers from N.H. Yates
The people at Dunkirk are known by those in the HVAC and plumbing industries for delivering innovative, efficient and dependable heating products. At N.H. Yates, we are proud to represent the entire line of Dunkirk Gas Boilers. In this post, we will be focusing specifically on Dunkirk Condensing Gas Boilers. When choosing a condensing boiler, Dunkirk offers a variety of choices to meet a variety of needs. The most recent model of Dunkirk Condensing Boiler utilizes an innovative vertical mounted helical fin tube heat changer that boasts a 95% AFUE rating. In addition, these modulating sealed combustion boilers feature built-in Outdoor Temperature Rest that reduces heating costs. Here are a few of the most popular models of Dunkirk Condensing Gas Boilers.
Dunkirk Helix VLT
The Dunkirk VLT Condensing Gas Boiler is a wall hung unit that features built-in primary and secondary piping and a built-in low water cut off. The Helix VLT works on a 5:1 turn down ratio and is approved for PVC, CPVC, and polypropylene vent systems. And of course, the Helix VLT is low maintenance, and self-cleaning.
Dunkirk DCC/DCB High-Efficiency Wall Mounted Modulating Condensing Boiler
The Dunkirk DCC/DCB high-efficiency wall mounted modulating condensing boiler features AI Control Technology that automatically sets up the boiler during the initial setup and recognizes natural or LP gas with no conversion kit required. In addition, the AI Control system continuously monitors combustion and adjusts gas and air flow to optimize combustion and fuel savings. Both the DCC/DCB models have a 7:1 turn down modulation ratio in DHW mode and a 5:5:1 ratio in heating mode.
Dunkirk DMG 380 High-Efficiency Condensing Hot Water Boiler
The DMG 380 High-Efficiency Condensing Hot Water Boiler has a company floor standing design with an optional plug-and-play, CSD-1 kit available for the unit. In addition, the DMG 380 has a 10:5:1 modulation turn down ratio and a high-limit electronic ignition boiler control module. The unit also comes equipt with a digital temperature display with diagnostics and programmable settings.
Dunkirk Helix VX Vertical Laser Tube Wall Hung Stainless Steel Modulating Condensing Boiler
The Dunkirk Helix VX is the Rolls Royce of modulating condensing boilers. The Helix VX is a low maintenance, self-cleaning, heat exchanger and was designed to withstand up to 150 psi MAWP. In addition, this unit is approved for PVC, CPVC, and polypropylene venting and is rated Energy Star 2018 Most Efficient. Finally, the Helix VX comes with a 15-year limited manufactures warranty plus a first year $500 heat exchanger labor warranty.
Maxitrol Gas Combination Controls
Maxitrol Combination Controls from N.H. Yates!
Gas valves are used to regulate the flow of flammable gases to and from a boiler or other gas equipment. Redundant gas valves control the passage of gas to the burner in a gas furnace or other gas-fueled devices. The purpose of a redundant gas valve is to allow the pilot valve operator, or, the main valve operator to shut off the flow of gas to the main burner. This redundancy creates more options and allows opportunities to keep the gas from the burner whenever necessary. Maxitrol Combination Controls are perfect for use in many applications such as gas boilers, power burners, spa heaters, wall furnaces, gas fires, patio heaters, agricultural heaters, and commercial cooking appliances. In addition, these combination controls are suitable for natural, manufactured, mixed gases, liquefied petroleum gases, and LP gas-air mixtures. At N.H. Yates, we are proud representatives of the entire line of Maxitrol products, including the Maxitrol Combination Controls.
Models of Maxitrol Combination Controls
Maxitrol Combination Controls for gas equipment come in several models that are appropriate for different application and needs. Here is a brief outline of each model and their capabilities:
Maxitrol Combination Control Model CV100
The CV100 is a single solenoid shut-off valve with an integrated pressure regulator. This model gas regulator is used for applications with high capacity pilot lines such as gas boilers and power burners.
Maxitrol Combination Control Model CV200
The CV200 is a dual-solenoid shut-off valve with an integrated pressure regulator. The CV200 is a redundant combination control that is used in direct spark or hot surface ignition applications. This unit eliminates the need for a standing or continuous burning pilot flame. Some appropriate applications for the CV200 include direct vent gas-fired baseboard heaters, space heaters, wall furnaces, water heaters, gas fireplaces, and commercial cooking appliances.
Maxitrol Combination Control Model CV300
The CV300 is a dual solenoid shut-off valve with an integrated pressure regulator, however, an optional pressure regulated pilot gas outlet is available. Appropriate applications for the CV300 include gas fires, commercial cooking appliances, and patio heaters.
The SR Series of Maxitrol 2 Stage Regulators
The SR Series of Maxitrol 2 Stage Regulators
Most two-stage regulator systems are made of two single stage regulators that operate in unison to reduce the pressure gradually in two stages rather than one. During the first stage, the pressure of the gas reduces to a preset level and is then passes on to the second stage. During the second stage, the regulator adjusts the pressure so the flame ignites and remains at the desired level. However, it’s no longer necessary to install two separate regulators on a unit if you use Maxitrol 2 Stage Regulators. That’s the Maxitrol SR series’ dual manifold system combines both gas pressure regulating and flame staging in a single unit. Some common applications for the Maxitrol’s 2 Stage Regulators include direct-fired heaters, hi-lo control (for outdoor heaters), LP natural gas switchover and industrial processing.
Maxitrol 2 Stage Regulators Specs
Maxitrol 2 Stage Regulators are made from solid aluminum and are available in 3/8″ thru 1″ threaded connections. All of SR series regulators are compatible with both NPT or ISO7-1 threads. The SR series is suitable for natural gas, manufactured gas, mixed gasses, liquefied petroleum gases, and LP gas-air mixtures. All models may be powered by a 24 volt AC transformer. When the unit’s coil is energized, the appliance is a lowe fire. When the coil is de-energized, it is high fire. Continous regulation is maintained to hold the electricity set outlet at constant pressure.
