Condensate discharge

The boiler condensate drain must be made of corrosion-

resistant material.

The following materials are suitable for the condensate

drain:

- PVC

- PP

ABS

The minimum inner diameter of the con-

densate drain must be 15 mm. The con-

densate drain must be sufficiently incli

ned

it is not necessary to neutralise condensate

from an oil-fired condensing unit of up to 120

kW drained together with domestic waste

water from a private household.

CH:

For the UltraOil

, the fuel used must be hea

ting oil EL low-sulphur. As a rule, neutralisati

on of the condensate is not necessary. Local

regulations pertaining to condensate dischar

ge must be observed.

For the UltraOil

, the fuel used must be

heating oil EL low-sulphur. Neutralisation is

therefore unnecessary. Regarding the di

scharge of condensate, the local regulations

and the ATV (Sewage Engineering Associati

on) data-sheet must be observed.

4.9

Setting the temperature regulators

Basic setting of the controller is carried out by the heating

contractor. Selection and setting of the various heating

programmes in accordance with the operating manual.

4.10 Safety valves

The heating system and hot water system must each be

protected with one safety valve against unauthorised high

pressures. The discharge capactiy of the valves must

correspond with the boiler’s maximum nominal heat out

put. The valve must be installed in the flow line in the

immediate vicinity of the boiler.

4.11 Charging pump (boiler with water heater)

Speed of rotation and output must correspond to the re

quirements of the water heater. Setting carried out by the

heating installation engineer.

4.12 Heating pump

Speed of rotation and output must correspond to the re

quirements of the system. They are to be set by the hea

ting installation engineer.
