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 fl ow must not be obstructed.

2.  Damage or deterioration which could cause improper venting or 

leakage of combustion products.

Be sure the vent piping is properly connected to prevent escape of 
dangerous fl ue gasses which could cause deadly asphyxiation.

Obstructions and deteriorated vent systems may present serious 
health risk or asphyxiation.

Chemical vapor corrosion of the fl ue 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 fl ue and venting before resuming operation 
of the water heater.

Flood damage to a water heater may not be readily visible or 
immediately detectable. However, over a period of time a fl ooded water 
heater will create dangerous conditions which can cause DEATH, 
SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Contact a 
qualifi ed installer or service agency to replace a fl ooded 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 the hot surface igniter assembly for proper fl ame 
characteristics and ignition sequences. This can be done by removing 
the Outer Door and viewing the main burner operation through the 
Viewport on the Inner Door, see Figure 1. The main burner should 
provide complete combustion of gas, ignite rapidly, give reasonably 
quiet operation, and cause no excessive fl ame lifting from the burner 
ports. If the proper fl ame characteristics are not evident (see Figure 
20), make sure that the fl ow of combustion and ventilation air is not 
blocked on the Air Intake Screen at the base of the water heater (see 
Figure 21), the Lint screen on the blower assembly (see Figure 1), 
and in the venting system.
  
You should also check for sooting. Soot is not normal and will impair 

proper combustion. A visual inspection of the main burner and HSI 
igniter assembly should also be done at least once a year, see Figure 
20.

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 fi re causing death, serious injury, or property damage.

In the event your burner or burner air openings require cleaning, turn 
the blower switch to the “OFF” position and allow the burner to cool. 
Call a service agency to remove and clean the burner and correct the 
problem that required the burner to be cleaned.

Vacuum around base of water heater for dust, dirt, and lint on a 
regular basis.

This water heater unit is supplied with a plastic Air Intake Screen that 
will fi lter and prevent lint build-up on the bottom of the fl ame arrestor 
of this heater. To prevent the lint build-up on the arrestor, the lint 
screen must be installed on the Base Pan with the “arrows” pointing 
upwards as shown in Figure 21. If the Air Intake Screen is missing 
from this heater, please contact your service agency or local installer 
for a replacement part.
