Troubleshooting guide

An automatic gas shut-off device (ECO) is incorporated in the sensor and control board which will shut off all gas supply to the burner and pilot if the
water heater temperature exceeds 200°F (93°C). Should the ECO function (open), the water temperature should be reduced to approximately 120°F
(49°C) and follow applicable Lighting Instructions to place the water heater in operation. The water heater must have the problem corrected by a
qualified service person before putting the water heater back in operation. It is recommended that all service work be performed by a qualified service
agency.
If the water heater is to remain idle for 30 days or more or is subjected to freezing temperatures while shut off, the water heater and piping should be fully
drained (See “To Drain the Water Heater”) and the drain valve should be left fully open.
Burner Flame Check
At the time of installation and at periodic intervals (about every 3 months), a visual check of the pilot and burner flames should be made to determine if
they are burning properly. No adjustment to the air shutter should be required for this heater. The burner flames should be blue with yellow tips. A blue-
orange flame is characteristic of operation on liquefied petroleum (LP) gas. If the burner flame does not appear as described, an air shutter adjustment
may be required. The burner tube flames should light smoothly from the pilot.

WARNING
Do not run out of propane gas. Damage to the water heater may occur.
Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for
a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the
possibility of injury under these conditions, we recommend the hot water faucet to be open for several
minutes at the kitchen sink before you use any electrical appliance which is connected to the hot water
system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipes as
hot water begins to flow. Do not smoke or have open flame near the faucet at the time it is open.
WARNING
Water heaters are heat producing appliances. To avoid damage or injury there must be no materials stored against
the water heater or vent system, and proper care must be taken to avoid unnecessary contact (especially by
children) with the water heater and vent system. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE
MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY OF THIS
WATER HEATER, VENT SYSTEM OR IN ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER
HEATER OR VENT SYSTEM.
WARNING
IMPORTANT- In the event of an emergency, turn off the gas and electric (if applicable) to the appliance.
IMPORTANT- 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.
