NOTICE

Connection of the drinking water installation should be performed according to the national secondary drinking water regulations.

Do NOT use toxic chemicals, such as are used for boiler treatment in potable water heating systems used for space heating.

The sanitary water pipes can be connected to the installation by use of adapter fittings. The cold water inlet on the Combi boilers must be equiped with the following components (counted in the water flow direction):

Flow regulator valve (supplied), Safety group, Expansion vessel 87 PSI / 6bar (potable water, blue).

The 3/4" NPT adapter fitting with flow reducing valve must be fitted in the cold water connection.

A flow regulator valve is supplied with the boiler in a 3/4"NPT adapter fitting. The flow 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 flow reducing valve.

NOTICE

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

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 fill 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 fill 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 certified PVC or CPVC pipe, fittings and cement.

Periodic cleaning of the condensate disposal system must be carried out. See the Rinnai Boiler Application Manual for further information and for a piping

diagram for the condensate.
