10 Starting up: Filling and de-aerating the boiler and installation

CAUTION

Observe the following rules of safety:

- All work on the unit must take place in a dry environment.

- Rinnai units may never be in operation without their housing, except in connection

with maintenance or adjustments (see Chapter 132 and 14).

- Never allow electrical or electronic components to come into contact with water.

NOTICE

Carry out the following tasks in connection with maintenance, etc. to an already-

installed unit:

- Shut down all programs

- Closethegasshuto󰀨valve

- Shuto󰀨thepoweratthemainpowerswitch

- Close the service valves (system supply and return)

NOTICE

Take note of the following when maintenance or adjustments are needed:

- The unit must be able to function during these activities; for this reason, the unit’s

supply voltage, gas pressure and water pressure must be maintained. Ensure that

this is not a source of potential danger during these activities.

Following maintenance or other activities; always check the installation of all

parts through which gas ows (with bubble test using leak-search spray).

10.1 Requirements of the water system

Beforellingtheheatingsystem,thecompletesystem,includingallzones,mustbe

thoroughlycleanedand ushedtoremove sediment.Flushuntil clean waterruns

system, but not the boiler. Always use Rinnai approved antifreezes. See the list at

the end of this chapter. Never use reverse osmosis, deionized, or distilled water for

llingtheheatingsystem.

Do not use petroleum-based cleaning or sealing compounds in the boiler

system. Damage of seals and gaskets in boiler and system could occur,

resulting in property damage.

Thecentralheatinginstallationneedstobelledwithpotablewater.

Use only potable water or approved glycol for lling the heating system.

When the water hardness of the lling water exceeds > 10.5 gpg (200 mg/L) the

water has to be treated until below the maximum value of 10.5 gpg (200 mg/L).

The pH value of the installation water must be between 6.5 and 8.5.

Check the pH value using proper equipment or by having the water analyzed by a

water treatment company.

IfpHdi󰀨ersfromabove,contactRinnaiengineeringforfurtherassistance.

Component or product damage as a result of failing to adhere to the water

quality requirements will not be covered by the limited warranty.
