5. Inspect the venting system for obstruction, leakage
or corrosion at least once a year.
6. Keep the boiler area clear and free from combustible
materials, gasoline, and other flammable vapors and
liquids.
7. Be sure that all combustion air and ventilation
openings are unobstructed.
8. The JX has easy access through the top cover
and the flue collector for inspection of the heat
exchanger. It is critical to ensure that the flue
collector sits in the proper position so that no flue
products will escape into the living area of the
building.
9. If the boiler is not going to be used for long periods
of time in locations where freezing occurs, it should
be completely drained of all water. To accomplish
this, there is a drain valve on the right side of the
boiler which can be opened. This will drain the right
side of the boiler. There are two plugs located on
the left side of the heater which can be accessed by
removing the side panel which must be removed to
drain that side. Both sides must be drained.
For complete details on Maintenance and
Troubleshooting for this boiler, please refer to
the Installation and Operating Manual, available
online at the manufacturer's website.
