If your Rinnai Furnace cuts off without a clear reason, it might be due to dirty filters causing the heater to overheat. Check whether the filters are blocked.
What to do if air filter blocked in Rinnai Furnace?
Clean the air filter of your Rinnai Furnace.
How to troubleshoot a Rinnai Furnace that does not operate?
If your Rinnai Furnace isn't operating, several factors could be the cause. First, ensure the heater is properly plugged in. Check your fuse box or breaker panel to see if any fuses have blown or breakers have tripped. Verify there isn't a power failure in your area. A blocked air filter or obstructed hot air outlet could also be the culprit, as could a blocked flue. Check these components to ensure proper function.
Why is my Rinnai Furnace not heating the room?
If your Rinnai Furnace isn't heating the room adequately, several factors could be responsible. Begin by checking if the air filter is blocked, as this can impede airflow and reduce heating efficiency. Ensure that the thermostat is set to a sufficiently high temperature. Verify that the warm air outlet isn't blocked by any obstructions. Confirm that all doors and windows in the room are closed to prevent heat loss. Finally, consider whether the furnace was correctly sized for the space it's intended to heat.
Why warm air does not flow when the burner lights in Rinnai Furnace?
If warm air doesn't flow when the burner lights on your Rinnai Furnace, note that the fan starts automatically after a short delay.
Why convection fan continues to run after turning OFF Rinnai Furnace?
If the convection fan in your Rinnai Furnace continues to run after you turn it off, this is normal. It's designed to remove residual heat from the heat exchanger and will stop when the heater cools down.
Why does my Rinnai Furnace produce smoke on first use?
If your Rinnai Furnace produces smoke or strange smells during the first trial light up after installation, this is typically due to grease, oil, or dust on the heat exchanger. This issue should resolve itself after a short period of operation.
Why is steam discharged from the flue terminal of my Rinnai Furnace?
If you notice steam being discharged from the flue terminal of your Rinnai Furnace, especially on cold days, this is normal behavior for high-efficiency appliances. It's simply water vapor being released.
Why Rinnai Furnace makes clicking noises at ignition?
Sharp clicking noises at ignition or when the Rinnai Furnace cuts down on the thermostat are simply expansion noise from the heat exchanger.
Why Rinnai Furnace makes a rumbling noise?
The low, rumbling noise you hear when the thermostat operates in your Rinnai Furnace is the sound of the solenoid gas valves opening and closing.
The Rinnai EX17DT and EX22DT are direct vent wall furnaces designed for efficient heating in various settings. These models, also known as RHFE-436FTA and RHFE-570FTA respectively, are forced combustion, forced convection, and flued gas furnaces, ensuring a consistent and comfortable heat output.
The primary function of these Rinnai wall furnaces is to provide space heating. They operate by drawing in combustion air from outside through a direct vent system, burning either natural gas or liquefied petroleum (LP) gas, and then expelling combustion byproducts back outside. This direct vent design ensures that no combustion air is drawn from inside the living space, contributing to improved indoor air quality and safety. The forced convection mechanism uses a fan to circulate heated air throughout the room, ensuring even heat distribution.
The furnaces are equipped with an electronic thermostat that allows users to set desired temperatures within a range of 60-80°F (16-26°C), adjustable in 2°F (1°C) increments. This precise temperature control helps maintain comfort and optimize energy usage. Ignition is handled by an electronic spark ignition system, providing reliable startup. The burners are made of stainless steel (Bunsen type), known for their durability and efficient combustion.
The Rinnai EX17DT and EX22DT furnaces offer versatile usage options. They are approved for installation in manufactured homes (USA only), mobile homes, and residential settings. A key feature is their convertibility between natural gas and LP gas, provided the necessary conversion provisions are made. This flexibility makes them suitable for a wide range of fuel availability. They are also approved for commercial settings, expanding their application beyond residential use. Furthermore, these furnaces can be installed at altitudes up to 10,200 ft. (3,109 m), making them suitable for high-altitude environments where other heating systems might struggle.
For installation, the furnaces come with a flue manifold "A" Vent Kit (FOT-151) and a full-size wall template located on the furnace carton box, simplifying the setup process. Installation and wall mounting hardware, along with an installation and operation manual, are also included to guide users through the setup.
Several optional items enhance the functionality and adaptability of these furnaces. An Extension Kit is available to extend the exhaust line and air intake hose between the flue manifold and the furnace, offering more flexibility in vent placement. Remote Thermostat Installation Kits (Part # 204000045 for US and # 204000048 for Canadian installations) allow for convenient temperature control from a different location in the room. Gas Conversion Kits are also available for both models to switch between natural gas and propane, providing further fuel flexibility. Different vent kits (S, A, B, C, D) are offered to accommodate various wall thicknesses, ranging from 3 inches (75 mm) to 31 1/2 inches (800 mm), ensuring a proper and secure installation regardless of the wall structure.
The furnaces include a humidifier tray with a capacity of 2.1 pints (1,000 cc), which can help add moisture to the air, improving comfort, especially in dry climates. A manual gas shut-off valve is also provided for safety and convenience during maintenance or emergencies.
Ease of maintenance is considered in the design of the Rinnai EX17DT and EX22DT. The flue system requires proper termination to atmosphere using only certified components to maintain warranty validity and safe operation. The installation and operation manual provides detailed instructions for proper use and care.
For servicing, specific clearances to combustibles and for maintenance access are recommended. A minimum clearance of 10 inches (254 mm) from the sides and top, and 40 inches (1 m) from the front, is advised to allow technicians sufficient space to work on the furnace. The design also includes a back spacer set, which helps maintain the necessary clearance from the wall. These clearances ensure that components are accessible for inspection, cleaning, and repair, contributing to the longevity and efficient operation of the unit. The direct vent design also means that the combustion chamber is sealed from the living space, reducing the accumulation of dust and debris inside the critical components, which in turn can simplify routine cleaning.
