CARING FOR YOUR WATER HEATER
Preventive Maintenance
Care Instructions
WARNING:
Failure to perform routine preventive maintenance can
prevent the water heaters and common venting system from
operating properly. Improper operation can cause carbon
monoxide dangers, excessive water temperatures, and
other potentially hazardous conditions resulting in death,
personal injury, and/or product damage.
Properly maintaining your water heaters and common vent
system will ensure dependable, trouble-free service.
User Preventive Maintenance
Refer to water heater's U&C manual for preventive
maintenance for water heaters. Establish and follow a
routine preventive maintenance program. The following
suggested items should be included in your program.
Common venting system
Periodically check all connections of vent pipes if they
are properly connected. Carefully inspect the entire
common venting system for any signs of cracks or
fractures, particularly at the joints between elbows or
other fittings and the straight runs of vent pipe. Check
the system for signs of sagging or other stresses in the
joints as a result of misalignment of any components in
the system. If any of these conditions are found, they
must be corrected.
Ball Siphon
The siphon prevents flue gas from flowing into the
water heater. Water or condensation should cover
a ball in the ball siphon completely. Periodically
check if the ball is completely covered by water or
condensation. Fill water until the ball is fully covered by
water or condensation. Also, periodically check if many
bubbles are seen in the siphon during water heaters
operate. If many bubbles are seen, stop operating water
heaters immediately, and contact a qualified service
technician or plumbing contractor.
