8.1 Annual startup & general maintenance
Regular Maintenance
- This Manual should be placed in a safe and dry
location near the Combination boiler. Maintenance
instructions should be carried out by the following
guidelines.
Maintenance procedures [ Daily ]
- Check that the boiler casing is closed.
Check if there is any problem with the Combination
boiler casing and the two upper and lower screws
are tightened well. Combination boiler casing must
be closed while it is running.
- Check the power source
.
Make sure that the power cord is correctly
connected. The main power line is connected to
the manual switch box inside a Combination boiler.
(Power line through the strain relief in the bottom of
the combination boiler casing and fix it.)
- Check the status of the control panel
Check status of the power supply. Please check for
any debris on the button.
Maintenance procedures [ Monthly ]
- Check the vent pipe.
Visually inspect the flue gas vent piping for detecting
any signs of blockage, leakage or deterioration
of the piping. Please contact a qualified service
technician immediately if you find any problem.
- Check the air inlet pipe.
Visually inspect the air inlet to be sure it is
unobstructed. Inspect entire length of air piping
for ensuring that piping is intact and all joints
are properly sealed. Call your qualified service
technician if you notice any problems.
- Check the relief valve.
Inspect the Combination boiler relief valve and
the relief valve discharge pipe for any signs
of weeping or leakage. If the relief valve often
weeps, immediately contact your qualified service
technician for inspecting the Combination boiler and
system.
- Check the condensate outlet.
While the Combination boiler is running, check the
discharge end of the condensate drain tubing.
Make sure that no flue gas is escaping from the
condensate drain tubing.
If flue gas is continuously escaping, it is a serious
problem. Call your qualified service technician for
inspecting the Combination boiler and condensate
line. Also, refill the condensate trap if problem
persists regularly.
-
Check the vent terminal screen vent
(rodent
screen).
If you encounter a problem of combustion
specifications, visually inspect the terminal screen.
And then replace it with spare parts or clean the
screens.
