    Rinnai M-Series combi boilers were designed with momentum in mind, focusing on key elements to allow for simple installation, operational performance and serviceability. Combining Rinnai's condensing boiler technology with an on-demand water heater, the M-Series combi boiler provides high efficiency home heating in a compact, efficient package. With a stainless steel heat exchanger, factory installed circulation pump and turbo fan, these boilers produce powerful and efficient heat without having to break the bank. Its lightweight and compact design, paired with an included mounting bracket, makes the Rinnai M-Series a quick and effective solution to your home heating needs.
  • High Efficiency Home Heating and Hot Water
  • Rinnai M-Series boilers boast an impressive 95.0% AFUE efficiency rating. A stainless steel heat exchanger promotes efficient heat transfer while the domestic hot water flow sensor helps modulate the boilers for increased performance.
  • Simple Installation
  • Its compact size and included mounting bracket allow the M-Series boiler to be installed easily and quickly. Flexible venting options and simplified setup parameters mean you'll have the boiler up and running in no time.
  • Easy-To-Use Interface
  • M-Series boilers feature a large display with a simple control interface. Simplified parameters and menu navigation allows for quick adjustments and service without the headache.
  • Product Includes
  • Liquid Propane Field Conversion Kit
  • Wall Mounting Bracket
  • Pressure Relief Valve
  • Condensate Collector Kit
  • Outdoor Reset Sensor
  • Vent Top with Integrated 3" PP Adapters
  • 3" PP to 3" PVC Adapter (Qty. 2)
  • 3" PVC to 2" PVC or PP Adapter (Qty. 2)
  • 3" x 5" Concentric Vent Adapter

M Series
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
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.
Condensing
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.
Direct 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.
Yes
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.
120000 BTU
Minimum Input Capacity
23500 BTU
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.
112000 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.
97000 BTU
Minimum Flow Rate
6.3 GPM
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
