3 Description of the boiler

The Rinnai Q boiler is a room sealed, condensing and modulating central heating

boiler, with an optional integrated DHW cylinder (integrated DHW on the Q175C only).

The QxxS boiler models have the ability to control a domestic hot water indirect tank.

The boiler is provided with a compact stainless steel heat exchanger with smooth

tubes. This design is a well engineered principle using durable materials.

The boiler burns gas for supplying heat. The heat is transferred in the heat exchanger

to the water in the central heating system. By cooling down the exhaust gases

condensate is formed. This results in high efﬁ ciency. The condensate, which has

no effect on the heat exchanger and the function of the boiler, is drained through a

condensate collector trap.

The boiler is provided with an intelligent control system (CMS Control Management

System). The boiler anticipates the heat demand of the central heating system or the

domestic hot water facility system.

When an outdoor sensor is connected to the boiler it will operate weather dependantly

using outdoor reset. This means that the boiler control measures the outside

temperature and supply temperature. With this data the boiler calculates the optimal

supply temperature for the installation.

6 Connecting the boiler

The boiler has the following connection pipes;

- The central heating circuit pipes.

These must be connected to the Plumbing Kit by means of adapter ﬁ ttings.

See further chapter 6.1;

- The gas supply pipe.

It is provided with a 3/4" male thread into which the tail piece of the gas valve can

be screwed. See further chapter 6.4;

- The condensation drain pipe.

It consists of an oval 1" (24 mm) plastic pipe. The drain pipe can be connected to

this by means of an open connection. If the open connection is ﬁ tted in a different

location, then the pipe can be lengthened by means of a 1 1/4" (32 mm) PVC

sleeve. See further chapter 6.6;

- The vent system and air supply system.

It consists of a concentric connection 3"/5" (80/125 mm). The boiler can be converted

to a twin pipe connection that will accept 80mm ﬂ ue and intake air or with the use

of the included adapters 3” PVC / CPVC ﬂ ue and intake. See further chapter 6.7.

- Cold and hot water pipes for domestic hot water (DHW).

Combi boilers only: These consist of 3/4" (15 mm) copper pipe and can be

connected to the installation by means of 3/4" M-NPT adapter ﬁ ttings. See further

chapter 6.5;

The pipes to be connected to the boiler must be cleaned before connecting in

order to prevent dirt from entering and damaging the boiler.

6.1 Central heating system

Connect the central heating system according to its instructions.

The boiler pipes can be connected to the installation by means of compression ﬁ ttings.

Reducers should be used for connecting to thick-walled pipe (welded or threaded).

When removing the plastic sealing caps from the pipes, dirty testing water may

drain from the boiler.

A Plumbing Kit must be ﬁ tted to the boiler.

The boiler, when used in connection with a refrigeration system, must be

installed so the chilled medium is piped in parallel with the boiler with appropriate

valves to prevent the chilled medium from entering the boiler.

The boiler piping system of a hot water boiler connected to heating coils located

in air handling units where they may be exposed to refrigerated air circulation

must be equipped with ﬂ ow control valves or other automatic means to prevent

gravity circulation of the boiler water during the cooling cycle.

6.1.1 Plumbing Kit installation

Rinnai supplies speciﬁ c Plumbing Kits with each boiler type, which must be ﬁ tted

directly underneath the boiler on the supply and return pipe. Find in chapter 5.3 the

dimensions. Use of the Rinnai boiler without the plumbing kit will void the warranty.

To protect the entire heating 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.

- Install shut-off valves immediately before and after the dirt particle ﬁ lter to allow

the trap to be cleaned.

- Position 3 (ﬁ gure 8) is a garden hose thread boiler drain that can be used to drain

the boiler or add water treatment additives to the system such as inhibitors or

glycol.

- Position 4 (ﬁ gure 8) is the supply connection for an indirect tank when used with

the optional 3-way valve kit.

- For information on locating the expansion tank and system ﬁ ll, please see the

Rinnai Boiler Applications Manual.

Thoroughly ﬂ ush all pipes and radiators. We recommend the use of a Rinnai

approved system cleaner. Please refer to the list of approved Rinnai system

cleaners in this chapter.

- Refer to the installation template and chapter 5.3 for the pipe connection dimensions.

The plumbing kit is not intended to support the weight of the piping. Appropriate

piping supports should be used to support all attached piping to the boiler and

plumbing kit.
