Q Premier Floor Standing Boiler

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 – How it Works

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.

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).

hot water, and DHW circulation return piping.
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

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

11. Bypass for system cleaning

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.

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
