Features
- Intelligent Hydronic Control
- Burnham's IQ system consists of two primary components: an IQ Option Panel and an Intelligent Hydronic Control. The IHC supports two setpoints, controls ignition, provides fan and circulator relays, and acts as an aquastat.
- IQ Option Panel
- The IQ Option Panel provides a standardized and simplified way to add functionality to your boiler. It supports Burnham's plug-and-play IQ Option Cards for outdoor reset, an auxiliary high limit, and low water cutoff.
- Compact Venting Technology
- All Series 3 boilers contain a draft diverter. By internalizing this component, the profile of the boiler and the space required for installation is reduced. The 305BNI-T also includes a vent damper to provide ideal combustion conditions.
- Durable Construction
- Cast-iron construction of the boiler sections contribute to the incredible longevity of Series 3 models. The heat exchanger is also made of cast iron, which allows it to accept lower return water temperatures.

Burnham is devoted to pushing the limits of heating technology and efficiency. Their ingenuity is responsible for some of the most efficient boilers on the market today. The Series 3 line of hot water boilers blends a reliable design with Burnham's cutting edge IQ Control System. Series 3 boilers save energy by doubling down on heat retention with an insulated jacket and plates. Possessing industry standard tapping locations, simplified venting, and exceptional efficiency, the 305BNI-T is an excellent replacement for older natural draft boilers or the perfect addition for new construction.
Product Note
A high altitude conversion kit is required for installations made at altitudes above 5,400'.

Medium
Medium
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
Fuel Type
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
Combustion Type
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
Vent Type
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
DHW Production
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.

Modulating/Staging
Modulating/Staging
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

Performance
AFUE
AFUE
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

Maximum Input Capacity
Maximum Input Capacity
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.
140000 BTU
DOE Heating Capacity
DOE Heating Capacity
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.
117000 BTU
Net I=B=R Capacity
Net I=B=R Capacity
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.
102000 BTU
Ultra Low NOx Emissions
Ultra Low NOx Emissions
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
