Maintenance Schedule
Water heaters are heat producing appliances. To avoid damage or injury there must be no
materials stored against the water heater or vent-air intake system, and proper care must be
taken to avoid unnecessary contact (especially by children) with the water heater and vent-air
intake system. UNDER NO CIRCUMSTANCES SHOULD FLAMMABLE MATERIALS, SUCH
AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY OF THIS
WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY LOCATION FROM WHICH
FUMES COULD REACH THE WATER HEATER OR VENT-AIR INTAKE SYSTEM.
The water heater should be inspected at a minimum annually by a qualified service technician
for damaged components and/or joints not sealed. DO NOT operate this water heater if any part
is found damaged or if any joint is found not sealed.
Following are the instructions for performing some of the recommended maintenance.
Unit inspection and adjustment should only be performed by a qualified technician.

1 Month:
1 Year:
Flushing Water Heater
1. Turn OFF the water heater electrical disconnect switch.
2. Open the drain valve and allow water to flow until it runs clean.
3. Close the drain valve when finished flushing.
4. Turn ON the water heater electrical disconnect switch.
Filling the Water Heater
1. Close the water heater drain valve. This water
heater utilizes a ball valve; when closing the
valve, the stem will spin indefinitely. Confirm it
is closed by ensuring the slot on the stem is
perpendicular to the valve body. If alternative
water connections are provided but not used,
make certain they are plugged (i.e. space
heating & alternate top connections).
2. Open the cold water supply shut-off valve.
3. Open several hot water faucets to allow air to escape from the system.
4. When a steady stream of water flows from the faucets, the water heater is filled. Close the faucets and
check for water leaks at the water heater drain valve, combination temperature and pressure relief valve
and the hot and cold water connections.
