3 Description of the boiler

Room sealed boiler

The boiler retreives its combustion air from outside then

discharges the ue gasses to

the outside.

Condensing

Retrieves heat as much as possible from the ue gasses. Water condensates on the heat exchanger.

Modulating

Stepless higher or lower burning according to the heat demand.

The Rinnai E boiler is a room sealed, condensing and modulating central heating boiler, with an integrated DHW fascility.

The boiler is provided with a compact stainless steel heat exchanger with smooth tubes. This design is a well thought out 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 efciency. The condensate, which has

no effect on the heat exchanger and the function of the boiler, is drained through 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 connected to the plumbing kit by means of adapter 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;

- Cold and hot water pipes for domestic hot water (DHW). These consist of 3/4" (15 mm) copper pipe and can be connected to the installation

by means of 1/2" M-NPT adapter ttings. See further chapter 6.5;

- The condensation drain pipe.

It consists of an oval 1" (22 mm) plastic pipe. The drain pipe can be connected to

this by means of an open connection. If the open connection is 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 ue and intake air or with the use of the included adapters 3” PVC/CPVC ue and intake. See further chapter 6.7.

NOTICE

The boiler has a self-adjusting and self-protecting control system for the load and the pump capacity. By this means the temperature difference between the supply and return water is checked and controlled.

If the installation resistance is over the stated value; the load will be adjusted until an acceptable temperature difference between supply and return water has been obtained. If, after this, the temperature difference is still not acceptable then the boiler will switch off and wait until an acceptable temperature has arisen. If an unacceptable temperature is detected, the control will repeatedly try to achieve

water ow over the boiler. If not the boiler will switch off. The electrical side of an external circulation pump (g. 6, pos. 8) can be connected

to the Control Tower. This pump thus switches simultaneously to the boiler pump. The maximum absorbed current consumption of the external circulation pump may not exceed 120V, 2 Amp. If a pump with a larger current draw is required an isolation relay must be used. See the Rinnai Boiler Applications Manual for further information. The extra external pump must be selected according the installation resistance and

required ow. As standard the boiler is provided with a water lter in the return pipe of the boiler, so

that debris of the central heating water is prevented from affecting the boiler.

When using more than one boiler in an installation please refer to the cascade installation instructions.

The boiler is designed to be used on pressurized heating systems only.

6.2 Expansion tank

The E-Series boilers are equiped with an internal expansion tank. The tank of the E75CN and E75CP is positioned inside the boiler casing. This expansion tank has a pre-charge pressure of 14.5 PSI / 1 Bar and a capacity of 2.1 gallon / 8 litres. The tank of the E110CN and E110CP is positioned directly beneath the boiler and together with the casing forms a single entity with the boiler. The casing can be removed by pulling forwards. The expansion tank has a pre-charge pressure of 14.5 PSI / 1 Bar and a capacity of 3.1 gallon / 12 litres. If a larger capacity expansion tank is needed for the installation a standard expansion

vessel should be tted additionally.

NOTICE

In that case choose an expansion tank volume, of which the summary is geared to the installation’s water capacity. The pre-charge pressure depends on the installation height above the expansion tank. Fit the expansion tank into the return pipe as close as possible to the boiler. The extra expansion tank should be sourced locally. Please refer to the expansion tank manufacturer for further information.

Fill the expansion tank to a minimum of 14.5 psi.

connection.

A ow regulator valve is supplied with the boiler in a 3/4"NPT adapter tting. The ow regulator valve ensures that a quantity of water is supplied which has a outlet

temperature of 120°F (assuming a cold water temperature of 45°F). The quantity of water is virtually unaffected by the water pressure.

When there is a water pressure lower than 22PSI / 1.5 bar it is advisable to remove the inside mechanism of the ow reducing valve.

6.6 Condensate drain pipe

This boiler produces condensate. Condensate must be drained otherwise the boiler will not function and can cause property damage.

NOTICE

The condensation drain pipe should be connected to a drain in the building by means of an open connection. By this means the possibility of drain gases effecting the boiler

is prevented. The drain connection should have a minimum diameter of 1.3" / 32mm.

Install the condensation drain pipe according to the applicable rules and regulations.

If the condensate outlet of the boiler is lower than the public sewage system a condensate pump must be used. The condensate produced by the boiler has a pH value between 3 and 4. Install a neutralization unit if required by the local code. It is recommended, but not required to install a condensate neutralizer.

Do not drain the condensation water to the external rain gutter because of the danger of freezing and blockage of the drain.

Before putting the boiler into operation ll the condensate trap with 1.27 cups / 300 ml of water. If the boiler will be installed in a high temperature installation such as baseboard, then ll the condensate trap with mineral oil instead of water.

Use materials approved by the authority having jurisdiction. In absence of such authority, PVC and CPVC pipe must comply with ASTM D1785, F441 or D2665. Cement and primer must comply with ASTM D2564 or F493. For Canada, use CSA or ULC certied PVC or CPVC pipe, ttings and cement.

NOTICE

Consult local and state codes pertaining to special building code and re department requirements. Adhere to national code requirements.

Follow the listed maximum length of vent systems, which are boiler output dependent. The maximum permissible lengths are listed in table 9, chapter 6.7.6.

Decide how to install the exhaust and air intake system. You can choose between:

- Concentric system (see page 26)

The concentric connection is provided standard initially.

The boiler concentric connection diameter is 3"/5" (80/125 mm), to which the venting and air supply system can be tted, with or without elbow pieces. The maximum permissible pipe length

is displayed in table 9, chapter 6.7.6.

- Parallel system (see page 27)

The boiler can be converted to a parallel system with supplied adapters.

It is possible to use a parallel pipe connection of 2x 3". In this case a seperate supplied kit, with 2 vent adapters 3" (ø80mm), cover 5" (ø125mm), vent exhaust pipe and gaskets should be tted instead of the concentric vent adapter on top of the boiler. See gure 12 for installation.

The maximum permissible pipe length is set out in table 9, chapter 6.7.6.

- Room Air System (outdoor combustion air)

The boiler can use room air for combustion. If this option is selected the boiler must rst be converted to the Parallel system. A single exhaust pipe can then be tted. It is required to use a room air lter when using indoor air for combustion. The maximum permissible pipe length

is set out in table 9, chapter 6.7.6.

6.7.4 Recommended vent/air intake terminal position

NOTICE

CAUTION

NOTICE

Terminals should be positioned as to avoid products of combustion entering openings into buildings or other vents.

Maintain 12” of clearance above the highest anticipated snow level or grade or, whichever is greater. Please refer to your local codes for the snow level in your area.

The termination shall be at least 4 feet (1,220 mm) for the US and 6 feet (1,830 mm) for Canada distance from electric meters, gas meters, regulators and relief equipment. (for room air application only)

Horizontal vent systems should always be installed sloping towards the boiler (min. 21 mm/m, 1/4 “/ feet), in order to avoid condensate retaining in the vent system. With the condensate running back to the boiler the risk of ice forming at the terminal is reduced.

The whole route of the vent system must be installed upwards, never downwards, completely nor partly.

Place pipe supports every 4 feet (1219 mm) of horizontal run, beginning with the support near the boiler to prevent movement in ttings and allow boiler to be free from any strain or weight on boiler or ttings.

The terminal should be located where dispersal of combustion products is not impeded and with due regard for the damage or discolouration that might occur to building products in the vicinity (see g 14 and 15).
