Q Premier Floor Standing Boiler Rinnai Q Premier Boilers Rinnai has added two Q Premier condensing boiler models to supplement the Rinnai wall hung boilers. The Rinnai Q Premier series is a floor standing version of our high efficiency condensing boilers. The Q Premier boiler combines features found in a combi model boiler and a heating only boiler (paired with an indirect tank) into a single appliance. With the single cabinet design, Rinnai can offer its customers a floor standing boiler that provides space heating plus can deliver a large volume of domestic hot water. Q Premier Features & Specs. • Two Models – QP130N / QP85N. • AFUE = 96.1% (QP130N) 96.5% (QP85N). • Exceeds SCAQMD 1146.2 Low NOx requirements. • Proprietary stainless steel heat exchanger. • ASME = Yes • Modulating Ceramic Premix burner. • Direct Vent combustion (concentric & twin pipe vent adapters included). • 24 gallon stainless steel indirect DHW tank. • First Hour Rating = 211 gallons (QP130N), 141 gallons (QP85N). • Domestic Hot Water Priority. • Integrated low loss header. • Top, left, or right side pre-bend kits provide easier installation. • Recirculation capable. • NG Only – conversion kits sold as accessory. • Weight = 243 lbs. Q Premier – How it Works OSS HEX Heating System Boiler Pump Diverting Valve Diverting valve (3-way valve) manages flow between the heating system and the domestic hot water system, giving priority to domestic. Plate HEX Domestic Out Pump Recirc Return T3 Sensor Tank • • • Inside tank, a plate is used to keep incoming cold water at bottom of tank Domestic In Domestic line “in” enters in bottom of tank. T3 sensor monitors water temp and - pump energizes based on water temp. Draws colder water from bottom of tank – heats water through plate HEX and returns heated water to top of tank (tank design maintains stratification).

Fitting the Boiler Lift the boiler only by the boiler grips on bottom and rear wall Note: wear protective gloves to protect from sharp edges. Lift the boiler in its upright position and place the boiler in its defined place. Use the adjustment feet to position the boiler vertical using a plumb rule. To avoid personal injury please follow these recommendations: • Always lift with 2 people or use special equipment • When lifting boiler, bend the knees, and keep the back straight and feet apart • Do not lift and twist at the same time • Lift and carry boiler close to body • The boiler can be placed on most floor surfaces. The boiler is not allowed or approved to be installed on carpet flooring • The floor must be flat and of sufficient strength in order to securely hold and support the boiler’s weight and water content • Take note of the necessary space around the boiler for installation of the venting system, pipework and for servicing Clearances • The location of boiler must be free from freezing temperatures • Do not store or use gasoline or other flammable vapors or liquids in the vicinity of the boiler • Never use or store any chlorinated detergents or halogenated hydrocarbons in proximity of the boiler • The boiler is intended for indoor installations only clearances to the boiler Q Premier Pre-bend Kits Shown with Top Side Pre-bent Kits Integrated LLH Pre-bend kit installation instructions can be found in section 6.1.1 of the installation manual. Connecting Boiler • • The factory supplied pressure relief valve and temperature and pressure gauge must be installed before any shut-off valves The pressure relief valve and temperature and pressure gauge must be installed as shown below Installed PRV and T&P gauge on side Installed PRV and T&P gauge on top To ensure the correct heat transfer, the system piping should be increased in size upon exiting the boiler at the end of pre-bend kits to properly suit the system. Section 6.1.1, table 5, shows the correct pipe sizing based on maximum flow rate and Delta T. Boiler basic piping • A low loss header is pre-installed in the boiler, The low loss header is not provided with service valves. Service valves must be installed on supply and return connection pipes of the boiler • To protect the entire system we recommend installing a dirt particle trap in the return circuit. When the boiler is installed to an existing heating system this trap is required. Use of a Y strainer is not permitted as a substitute for a dirt trap Note: • Boiler pipes can be connected by means of NPT fittings • Dielectric fittings are not provided with the boiler Dielectric unions must be installed on the supply and return connection pipes of the boiler 1.

Temperature and pressure gauge Condensate Drain The condensation drain pipe should be connected to an approved drainage system (public sewage, septic, etc..) per local code guidelines. • • The condensate produced by Rinnai boilers has a pH value between 3 and 4. Install a neutralizer or neutralization agent (such as calcium carbonate) per local codes Condensate drain line Rinnai offers a condensate neutralizer designed to work with all boiler models. The neutralization kit comes with all the necessary fittings and mounting material. PVC pipe must be supplied by the installation contractor. Part number 804000074 Check with your local water authority for regulations regarding discharge of treated condensate to the drain or sewer system. Domestic Hot Water A thermostatic mixing valve is required to be installed on all QP Floor mounted boilers on the domestic hot water side to prevent scalding. The valve will regulate the water temperature leaving the hot water tank. • Rinnai recommends use of the Plumbing valve kit, WRIK-LF-F (3/4” NPT thread) when connecting the domestic water lines to boiler • Use of the plumbing valve kit will assist in flushing the storage tank in areas where water quality issues exist, as well as improve overall product serviceability Appropriate steps must be taken to ensure the storage tank does not become plugged by scale caused by hard water or sediment. Water hardness more than 6 to 7 grains of hardness for domestic water, a water softener must be installed on inlet side of DHW connection. If there is sediment in domestic supply, a sediment filter should be used to remove it before it enters tank. Domestic Hot Water • • The QP130N Floor standing boiler has a 24 gallon stainless steel charged indirect tank First hour rating of 211 gallons QP85N QP130N DHW flow @ 50°F ΔT gallon/min 3.1 4.1 DHW flow @ 27.8°C ΔT liter/min 11.73 15.5 DHW flow @ 75°F ΔT gallon/min 2.1 3.2 DHW flow @ 41.7°C ΔT liter/min 7.95 12.1 First Hour Rating gallon/hour 141 211 liter/hour 534 799 The boiler is provided with a factory installed connection for a domestic hot water recirculation line. A standard recirculation pump correctly sized for the system and tank can be used with the QP130N boiler. NOTE: If a recirculation line will not be connected to the boiler, the recirc connection on the pre-bend pipe must be capped off. Domestic Hot Water A pressure relief valve is pre-installed on the storage tank. 24 gallon DHW tank • The discharge should be piped to the ground or into a drain system to prevent exposure or possible burn hazards (follow local codes) • A cutout is provided on boiler to pipe the relief valve to the ground • The PRV must be manually operated once a year to check for correct operation Venting Examples Venting Options • Use only vent components listed with the boiler by CSA • Below is a table of current listed and approved vent systems—always refer to the installation manual shipped with each product for specific guidelines Commissioning • • Work on the boiler must be carried out by a licensed professional, using correctly calibrated instruments with current test certification The installation manual includes instructions that are intended for licensed professionals who have the necessary knowledge and are approved for working on heating and gas systems To commission the boiler , parts of casing have to be removed 1. 2. 3. 4. 5. 6. 7. 8.
