VENTING SYSTEM INSPECTION
At least once a year a visual inspection should be made of the venting
system. You should look for:
1. Obstructions which could cause improper venting. The combustion
and ventilation air flow must not be obstructed.
2. Damage or deterioration which could cause improper venting or
leakage of combustion products.
3. Rusted flakes around top of water heater.
Be sure the vent piping is properly connected to prevent escape of
dangerous flue gasses which could cause deadly asphyxiation.
Obstructions and deteriorated vent systems may present serious health
risk or asphyxiation.
Chemical vapor corrosion of the flue and vent system may occur if air
for combustion contains certain chemical vapors. Spray can propellants,
cleaning solvents, refrigerator and air conditioner refrigerants,
swimming pool chemicals, calcium and sodium chloride, waxes, bleach
and process chemicals are typical compounds which are potentially
corrosive.
If after inspection of the vent system you found sooting or deterioration,
something is wrong. Call the local gas utility to correct the problem and
clean or replace the flue and venting before resuming operation of the
water heater.
BURNER INSPECTION
Flood damage to a water heater may not be readily visible or immediately
detectable. However, over a period of time a flooded water heater will
create dangerous conditions
which can cause DEATH, SERIOUS
BODILY INJURY, OR PROPERTY DAMAGE. Contact a qualified installer
or service agency to replace a flooded water heater. Do not attempt to
repair the unit! It must be replaced!
At least once a year a visual inspection should be made of the main
burner and pilot burner, see Figure 16.

You should check for sooting. Soot is not normal and will impair proper
combustion.
Soot build-up indicates a problem that requires correction before further
use. Turn “OFF” gas to water heater and leave off until repairs are
made, because failure to correct the cause of the sooting can result in
a fire causing death, serious injury, or property damage.

BURNER CLEANING
In the event your burner needs cleaning, follow these instructions:
If inspection of the burner shows that cleaning is required, turn the gas
control knob clockwise (
) to the “OFF” position, depressing slightly.
NOTE: The knob cannot be turned from “PILOT” to “OFF” unless
knob is depressed slightly. DO NOT FORCE.
The burner needs to be removed for cleaning. Call a service agency to
remove and clean the burner and correct the problem that required the
burner to be cleaned.
HOUSEKEEPING
Vacuum around base of water heater for dust, dirt, and lint on a regular
basis.
