Add water to appliance
If you notice that the pressure on the pressure
gauge is below 1.0~1.2 bar, you will have to
add water to the appliance.
When the boiler is operated for the first time,
there may be some air stored in the system.
During operation the air will be removed, and
the system pressure will go down, so you may
need to add more water to the appliance if the
pressure goes below 1.0 bar. This is a normal
procedure.
Note:
If you are still adding water frequently after
a long period use, there may be a leak in the
heating system. Please check the system and
seal the leakage.
Precautions for gas adjustment
The gas boiler must be installed by an
installer/engineer according to the current
laws and regulations. Property loses and
person harm may occur because of incorrect
installation. The manufacturer will not take
any responsibility for that.
Before installation, ensure the new gas pipes
that are installed are clean.
The gas installer must make the following
checks before the first operation:
a). check the leak tightness of the gas pipe.
b). Adjust the gas pressure according to the
requirement of gas boiler.
c). The gas type must match the gas
requirement indicated in technical tag.
d). Gas supply pressure must match the
requirement indicated in technical tag.
e). Gas supply must match the requirement
of gas boiler, must be equipped with safety
and test system requested by the laws and
regulations.
Instruction of gas use:
The gas pipe cannot be used as the earth
connection of electrics.
Please close gas main valve when the user is
not at home for long periods, you should also
drain out the water from heating and hot water
system to avoid water freezing in the system.
What to do if you smell gas
If there is a smell of gas in the building,
proceed as follows:
Avoid rooms that smell of gas.
If possible, open doors and windows fully and
ensure air is circulating.
Avoid the use of naked flames.
Do not smoke.
Do not use any electrical switches, plugs,
doorbells, telephones or other communication
systems in the building.
turn off your gas supply at the meter (and
leave it switched off until you’re sure it’s safe
to turn it back on again).
If possible, close the gas stop cock on the
unit.
Warn the occupants in the building.
Leave the building.
If you can actually hear gas leaking, leave the
building immediately and ensure that no third
parties enter the building.
Alert the police and fire brigade when you are
outside the building.
Use a telephone outside the building to inform
the gas supply company or National Grid
Transco 0800 111999.
First operation
The installer is responsible for conducting
the first ignition and showing the user how to
use the appliance. The gas pressure must be
checked when conducting the first ignition.
Warning!
When in heating mode, the gas boiler will need
two minutes to reach its nominal capacity
after ignition. Within these two minutes, the
gas volume will be lower than the nominal
capacity gas volume; this setting is for the
purpose of safety ignition.
