Rinnai tankless water heater installation instructions
Installation requirements: The appliance must be installed, inspected, and leak tested by a licensed professional before use. Any improper installation could void the warranty.
The certified specialist should be skilled in installing tankless water heaters and possess the following abilities: gas sizing; connecting gas lines, water lines, valves, and electricity; understanding applicable national, state, and local codes plus installing venting through a wall or roof.
You are advised not to install the water heater at a location where water leaking from the appliance or conditions could cause harm to the area around it or the building’s lower floors. When it is impossible to avoid such places, it is advised that a suitable, properly drained drain pan be installed underneath the water heater. The pan must not obstruct the flow of combustion air.
The manual also instructs you not to block the flow of combustion and ventilation air. Also, do not place the water heater in an area with negative air pressure.
You must make sure that all water heater and venting clearances will be satisfied when choosing an installation location, and that the vent length will be within allowed ranges. Think about the installation setting, the water’s quality, and whether freeze protection is required.
The instructions for the water and gas line, power connection and condensation drainage can be found in their respective installation sections in the manual.
A water quality assessment should be taken into account when caring for your water heater. Water that is fit for human consumption must be free of corrosive substances, sand, dirt, or other pollutants.
The trained and qualified professional is responsible for making sure the water is free of any corrosive substances or substances that could harm or affect the Rinnai Tankless Water Heater. The Rinnai Tankless Water Heater might be damaged if the water’s chemical content exceeds the limits stated below.
The warranty does not cover component replacement due to water quality damage. The water must be treated and may need to be flushed more frequently if you install this water heater in a location where the water is known to be hard or to create scale buildup.
Rinnai tankless water heater maintenance
The manual advices that a trained and certified specialist must inspect this water heater once a year. After servicing, the skilled and qualified professional must confirm correct operation.
Cleanliness must always be maintained in the appliance’s control compartments, burners, condensation collection and its disposal system, vent screens, and circulating air passageways.
Verify the burner flame is the right color. Once lit, the flame must completely engulf the burner’s surface. The flame must have a consistent, clean, and blue flame.
It is important to check the vent system for damage or obstructions, such as snow or other debris. Contact a competent and certified specialist if the vent cannot be easily cleared because it is obstructed.
Hard water is the main source of scale build-up, which can be sped up by a high water heater temperature. Water must be fit for human consumption and clear of contaminants such as sand, debris, and caustic chemicals.
It is the installer’s responsibility to make sure the water doesn’t include any corrosive substances or other materials that could harm or impact the heat exchanger. Chemical levels in water that are higher than necessary have an adverse effect on the heat exchanger and cause damage.
The guarantee does not cover the cost of replacing a heat exchanger that has been harmed by poor water quality.
Rinnai tankless water heater increase temperature
To function, this water heater needs a specific flow rate. The specification page of this manual has information on this rate. When you don’t get hot water or the temperature of the water fluctuates between hot and cold, it may be because the water flow is below or nearly at the minimum flow rate.
In these situations, increasing the flow rate ought to fix the issues. Reduce the temperature setting if you are having problems with higher temperatures.
Due to less cold water mixing at the fixture, choosing a temperature that is closer to what is really used at the faucet will enhance the volume of hot water delivered to the faucet.
The temperature setting can only be changed between 98°F and 110°F while hot water is being delivered. Verify local codes to determine the highest water temperature that can be utilized in nursing homes, colleges, preschools, and all other applications that are open to the general public.
If power is lost after a freshly installed water heater with a controller has been off for at least 6 hours, the temperature will return to the predetermined setting of 104°F (40°C). The weather or the length of the pipe leading to the water heater may cause a difference between the temperature shown on the temperature controller and the heat at the tap.
