7. Operational Precautions
●Initial Installation
– Flush the water tank with clean water before the heater
is first installed. When the heater is not in use, please vent
the water tank to avoid freezing the water tank. The
company is not responsible for damage to the water tank
caused by freezing.
--Turn the circulating water pump on
-- Turn on the hot water tap in the
Kitchen and bathroom, until the air is vented, and water
tank is full, outcoming water is not discontinued
-- Test run before the heater is used. Carefully check the
leaks and safety conditions of all connections during the
test run. If there is heavy smoke, abnormal combustion
noise or gas odor, turn off the heater and unplug the fuse
to make it inoperable. It can be used after being repaired
by professionals.
– The odor may be emitted for a short time when the heater is
used for the first time. This is normal for the first few minutes
of the start of the run, it does not indicate that the heater is
malfunctioning.
●Seasonal Maintenance
– Before each heating season, a special inspection must
be carried out by a professional to carry out the following
maintenance work:
Check the inlet and outlet of air for contamination and
foreign matter.
Clean the external of heater
Check the circuit connections for rust and looseness.
Check whether the inlet and outlet of air is blocked or
damaged.
Check if a gas leak occurs or smells of gas:
●Long-term halt – When the heater is not used for a long
time, it should be run every 4 weeks for about 10 minutes
each time to prevent the mechanical components such as
solenoid valves and combustion air fans from
malfunctioning (get stuck).
– The air inlet and outlet of the heater must be kept free
from clogging and dirt, so that the warm air duct is
unobstructed to prevent overheating.
●Heater Lifetime
– The heat exchanger of heater should not be used for
more than 10 years. After expiration, it must be replaced
with genuine parts and replaced by the heater
manufacturer or its authorized agent.
– The exhaust pipe from which the heater emits exhaust
gas must be renewed with genuine parts when the usage
time reaches 10 years.
- It is the responsibility of the operator to replace the gas
pressure regulator and gas line on a regular basis (by
expiration date).
Other Operational Precautions
– The tank must be descaled regularly, at least twice
a year.
