Fuel Type Learn More To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Altitude Learn More Because boilers suffer input loss at higher altitudes, manufacturers design boilers for specific altitude applications. To get the most out of your boiler, choose a model that fits your installation requirements.

Features
    Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing lasting heating solutions is seen in every boiler they make. The CGa is a compact, natural draft boiler. The low profile makes this boiler perfect for space conscious applications with chimney access. Solid construction and a good efficiency rating make the CGa an excellent value. A vent damper, draft hood, and Taco circulator are included. These components, coupled with easily accessible controls, make it easy to install and set your CGa up. Whether you are replacing an older boiler or beginning new construction, the CGa is an efficient, compact heating solution.
  • Efficiency-Boosting Insulation
  • Heat retention is critical to energy efficiency. Heat leakage represents energy use without any comfort gains. An extended, insulated steel jacket prevents heat from escaping the CGa and improves the efficiency.
  • Durable Construction
  • Reliability is one of the greatest ways a boiler can provide value. Weil-McLain wanted to be sure that you'll enjoy the comfort the CGa provides for years to come. With a steel base and burners and cast-iron boiler sections, they have done just that.

CGa
Medium Learn More Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Hot Water
Heat Exchanger Material
Cast Iron
Fuel Type Learn More To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type Learn More Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Conventional
Vent Type Learn More Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Chimney Vent
DHW Production Learn More DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.
No
Modulating/Staging Learn More Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

Maximum Input Capacity Learn More The Maximum Input Capacity describes how quickly the appliance will use fuel when delivering it's maximum capacity. The units may change depending on the fuel being used.
52000 BTU
AFUE Learn More AFUE (Annual Fuel Utilization Efficiency) measures the efficiency of combustion equipment over the entire heating season, and is calculated by dividing the amount of energy that is actually heating your home by the total energy contained in the fuel used by the boiler/furnace. Learn More
84 %
DOE Heating Capacity Learn More Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.
44000 BTU
Net I=B=R Capacity Learn More I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.
38000 BTU
Ultra Low NOx Emissions Learn More NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx. Learn More

The Weil-McLain 381357804 CGa-4 is for 0-2000ft altitude... suggestions for 7,000 ft in Santa FE, NM?
Tomb

Answer
Weil-McLain CGa boilers are available from the factory pre-configured for different altitudes.

For your high altitude application, you'll want to use the Weil-McLain 381357817 CGa-4, which is the version designed for 7k - 10k elevations.

High altitude conversion kits are also available for existing applications. For 7k - 10k elevations, this is the Weil-McLain 381354539 High Altitude Kit for NG.

Answer
The NG to LP gas conversion kit for current Weil-McLain CGa sizes 52k (CGa-25) through 210k (CGA-7) is the 510-811-946. Older boilers may require a different conversion kit depending on the year they were built. Thanks for your question!
