Installation instructions
Caution
Piping
Gas piping
Water supply piping
Installation of gas pipes must be performed by
gas professionals, or service provider.
Ensure that the gas used, as indicated on the boiler,
is the same as the gas supplied.
The gas shut off valve needs to be located close to
the boiler for easy access.
Check if there is any gas leakage after pipe
installation.
Install gas shut-
off valve nearby
A shut-off valve is needed at the point where the
water supply pipe starts.
The water supply pressure must be above
0.2kgf/cm (20kPa). If it is above 4.5kgf/cm , use
the pressure relief valve.
Before installation, all foreign substances in the
pipes must be removed and cleaned.
Refrain from using underground, or well water.
Instead, use water supplied by your local provider.
* If the water supply pressure is
too low and an auto water supply
pump is needed, do not install the
pump in the boiler room.
The pump’s automatic function can
cause a fire in the case of a gas leak.
Install a shut-off valve
at the water intake point
Hot water piping
Heating water piping
Hot water pipes shall be as short and simple as
possible and slanted 1/100~1/200 for easy drainage.
Make hot water
pipes simple
Heating water pipes should be installed in such
a way that there are no pipe connections which
make repairs hard and/or increase the possibility
of leakage.
Heating supply pipes and return pipes must be of
the same size.
The drain valve must be located at the lowest
position of the piping so that heating water can
be drained if necessary.
When connected to radiators, an automatic or
manual air vent device is necessary.
Caution
Water supply, hot water, and heating pipes must be insulated using at least 25mm insulation.
Attaching thermal heating elements to water supply and hot water pipes will help prevent winter freeze (optional).
Do not insulate filter, air vent, or drain valves.
