Maintenance continued-
The following maintenance should be performed by a qualified service
technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending on the
amount of use and the operating conditions of the water heater. Regular
inspection and maintenance of the water heater and vent-air intake system will
help to insure safe and reliable operation.
1. Annually check the operation of the thermostat.
2. The flow of combustion and ventilation air must NOT be restricted. Clear
the combustion air openings of any dirt, dust, or other restrictions.
3. At all times keep the water heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
4. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See Burner Flame Check. If
sooting or other burner anomalies are evident, shut down the water heater
by turning off the gas per the instructions listed in this manual or as listed
on the water heater.
5. Annually remove the inner door and main burner assembly to clean orifices
and related parts of any dirt or other foreign material. Inspect the burner
ports for obstructions or debris and clean with a wire brush as needed. Wire
brush and/or vacuum clean the combustion chamber as needed to remove
scale deposits and debris.
NOTE: It is imperative for proper operation of the water heater that the
inner door be replaced in the original location.
6. At least once a year, check the combination temperature and pressure
relief valve to ensure that the valve has not become encrusted with lime.
Lift the lever at the top of the valve several times until the valve seats
properly without leaking and operates freely.
WARNING
The ventilation system may be HOT.
WARNING
When lifting lever of the combination temperature and pressure
relief valve, hot water will be released under pressure. Be careful
that any released water does not result in bodily injury or property
damage.
WARNING
Do not run out of propane gas. Damage to the water heater may occur.
