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 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 call a qualified service agent 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

WARNING
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.

GENERAL
KEEP APPLIANCE AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE AND OTHER
FLAMMABLE VAPORS AND LIQUIDS.
Water heater maintenance includes periodic tank flushing and cleaning, and removal of lime scale. The unit should be
inspected and adjusted to maintain proper combustion. Refer to Table 5, “Suggested Maintenance Schedule”. A
periodic inspection of the venting system should be made.
BURNER FLAME CHECK
At the time of installation and at monthly intervals, a visual check of the burner flames should be made to determine if
they are burning properly. The main burner may be seen through the sight glass window on the front of the combustion
insert mounting bracket (Figure 27). The burner flames should be a blue flame near the burner surface in a uniform
flame pattern. Occasional yellow or white streaks are normal.
WARNING
Do not run out of propane gas. Damage to the water heater may occur.
