Important instructions

Installation and assembly instruction

• The installing company has given you installation

and assembly instructions. Keep this important

technical information securely, so that if necessary

the customer service mechanic can at a later date

discover the technical details on the spot.

Please close the main blocking clock

ahead of the gas meter as soon as you

smell gas and call the faults department

of your gas supply company.

To ensure that no poisonous exhaust gases develop,

the combustion air must ﬂ ow unhindered into the gas

boiler. Accordingly the ventilation opening provided (in

the room temperature-sensitive mode of operation)

(e.g. basement windows) may never be closed. Also

the boiler itself may not be turned off.

Always keep the room, in which your boiler is installed,

clean and turn off the burner before cleaning, since

dusty combustion air can lead to faults.

Faults

For your safety of the burner switches itself off auto-

matically in the event of faults in the burner system,

excessively low gas pressure, a gas leak or the ex-

ceeding of the maximum boiler temperature. Try ﬁ rst

to ignite the burner several times, after approximately

5 minutes of waiting period, by operating the clearing

button (Reset) on the control panel of the boiler. If that

does not succeed, please close the gas cock and

inform your customer service or heating engineer

Imperative requirement!

Perfect operation is only ensured if the

operating instructions are followed and

boilers as well as burners are maintained

regularly by a specialist

Faults and damaged caused by installation in unsui-

table areas, e.g. hobby rooms, workshops etc., as well

as by dirty operational agents (gas, water, combus-

tion air), unsuitable chemical additives to the heater

water, inappropriate treatment, incorrect installation

and damage by force do not fall under our warranty;

this also applies to corrosion by halogen compounds

e.g. from spray cans, paints, adhesives and solution

and cleaning agents

Maintenance and Control

Maintenance and control

Normally these are carried out by the specialist

on the occasion of the annual maintenance.

Nevertheless, you should carry out the follo-

wing controls and if necessary implement the

works described

Check water level

With excessively low water pressure in the sys-

tem (readable at the manometer), you should

inform your installer and/or reﬁ ll the water

Reﬁ lling the heating

• The boiler must be switched off! (disconnected from

the net)

• The stop valves in the heater ﬂ ow and return pipes

must be open.

• The connection between the boiler ﬁ lling/emptying

cock and the tap is established through a ﬁ lled

hose (no air should enter the heating system); this

should be unscrewed again after ﬁ lling, in order to

interrupt the connection securely.

• The water quality must correspond to the criteria

described on page 4 of the installation guideli-

nes.

• Slowly ﬁ ll in the water and check the water level at

the manometer (ask for the ﬁ lling pressure for your

system from the installer).

• The bleed valves on the heating elements must be

kept open, until only water ﬂ ows out.

Complete ﬁ lling and emptying should be implemented

by the heating expert

Note:

Never ﬁ ll cold water into the hot system

Boiler and burner

Have the burner and boiler as well as any neutralisation

mechanism checked and maintained periodically - DIN

4756 recommends at least one maintenance every

year. This maintenance is particularly important with

a high efﬁ ciency boiler such as this Hoval TopGas

in order to achieve the optimal annual consumption.

You can conclude a servicing contract with your he-

ating engineer or the responsible customer service

organisation.

Maintenance of the neutralisation

The local regulations of the responsible local

waste water authority must be complied with.

If the condensate of your boiler is neutralised before

introducing in the waste water, the neutralisation

system must be periodically cleaned and ﬁ lled with

new granulates. Follow the guidelines for your neu-

tralisation system.

Check before the start of the heating season

whether the siphon of the condensate drainage

pipe is ﬁ lled.

Hot-water supply

Regular controls increase the life span and efﬁ ciency

of any throughput and/or ancillary water heater. Du-

ring the cleaning submerged parts are removed. The

maintenance service will carry out this work.

In areas with calcium rich water the water heater

and/or the throughput heater - in the interest of an

economic hot-water supply - should be periodically

decalciﬁ ed (1 x annually). The water heater may not

be worked on with metal tools when decalcifying. With

highly calcium rich water the installation of a water

softening system is a good idea

4 204 473 / 01
