Maintenance
6.5 Pressure Relief Valve Maintenance
WARNING
Testing the pressure relief valve should only
be performed by a licensed professional.
Water discharged from the pressure relief
valve could cause severe burns instantly or
death from scalds.
WARNING
Before manually operating the pressure
reducing valve, check that the hot water is
discharged in a safe place. If water cannot
escape from the end of the drain, turn off
the air supply and turn off the power and
call a qualified person to determine the
cause. See the manufacturer of the
pressure relief valve for inspection and
maintenance requirements.
WARNING
Do not check the safety valve when the
water heater is in normal operation to avoid
hot water burns.

6.4 Visual Inspection of Flame
The burner must flame evenly over the entire surface
when operating correctly. The flame must burn with a
clear, blue, stable flame. See the parts breakdown of
the burner for the location of the view ports. The
flame pattern should be as shown in the figures
below.
Verify proper operation after servicing.
Ÿ The dirt will directly affect the normal function of
the safety valve function. It requires hot water
system maintenance of anti-fouling and anti-scaling
cleaning.
Ÿ The user must check the relief valve at least once a
year. When checking, turn off the water heater's
power supply and gas. Turn on the water inlet
switch to create pressure in the water system. Then
gently open relief valve handle until there is water
out and then gently close, if there is no water out,
indicating that the valve is invalid, this time should
immediately turn off the water heater water switch
and ask the service personnel to deal with. Before
operating the handle, check the discharge line
connecting the valve to ensure that the water
drained from the valve can be drained to a suitable
place.
