VENTING SYSTEM

Examine the venting system every six months for obstructions 

and/or  deterioration  of  the  vent  piping.  Check  all  vent  system 

connections for leakage and repair or reseal as necessary.
Remove all soot or other obstructions from chimney which will 

retard free draft.

INTAKE AIR SCREEN

The intake air screen is attached to the inlet end of the combustion 

blower. Inspect the intake air screen every six months. The intake air 

screen should be cleaned of any buildup of debris or foreign material.

TEMPERATURE-PRESSURE RELIEF VALVE TEST

•  Burn hazard.

•  Hot water discharge.

•  Keep clear of Temperature- 

Pressure Relief Valve 

discharge outlet.

It is recommended that the Temperature-Pressure Relief Valve 

should  be  checked  to  ensure  that  it  is  in  operating  condition 

every 6 months.
When checking the Temperature-Pressure Relief Valve operation, 

make sure that (1) no one is in front of or around the outlet of the 

Temperature-Pressure Relief Valve discharge line, and (2) that 

the water discharge will not cause any property damage, as the 

water may be extremely hot. Use care when operating valve as 

the valve may be hot.
To  check  the  relief  valve,  lift  the  lever  at  the  end  of  the  valve 

several times, see Figure 25. The valve should seat properly and 

operate freely.
If after manually operating the valve, it fails to completely reset 

and  continues  to  release  water,  immediately  close  the  cold 

water inlet to the water heater and drain the water heater, see 

Draining and Flushing on page 30. Replace the Temperature-

Pressure  Relief  Valve  with  a  properly  rated/sized  new  one, 

see Temperature-Pressure Relief Valve on pages 13-14 for 

instructions on replacement.

FIGURE 25.

If  the  Temperature-Pressure  Relief  Valve  on  the  water  heater 

weeps  or  discharges  periodically,  this  may  be  due  to  thermal 

expansion.
NOTE: Excessive water pressure is the most common cause of 

Temperature-Pressure  Relief  Valve  leakage.  Excessive  water 

system pressure is most often caused by "thermal expansion" 

in a "closed system." See Closed Water Systems and Thermal 

Expansion on page 13. The Temperature-Pressure Relief Valve 

is not intended for the constant relief of thermal expansion.
Temperature-Pressure Relief Valve leakage due to pressure build 

up in a closed system that does not have a thermal expansion 

tank installed is not covered under the limited warranty. Thermal 

expansion tanks must be installed on all closed water systems.

DO NOT PLUG THE TEMPERATURE-PRESSURE RELIEF 

VALVE  OPENING. THIS  CAN  CAUSE  PROPERTY  DAMAGE, 

SERIOUS INJURY OR DEATH.

Explosion Hazard

Temperature-Pressure Relief Valve

must comply with ANSI Z21.22

-

CSA

 4.4 and ASME code.

Properly sized temperature-

pressure relief valve must be

installed in opening provided.

Can result in overheating and

excessive tank pressure.

Can cause serious injury or death.

ANODE ROD INSPECTION

The anode rod is used to protect the tank from corrosion. Most 

hot water tanks are equipped with an anode rod. The submerged 

rod sacrifices itself to protect the tank. Instead of corroding tank, 

water ions attack and eat away the anode rod. This does not affect 

water’s taste or color. The rod must be maintained to keep tank 

in operating condition.
Anode deterioration depends on water conductivity, not necessarily 

water  condition. A  corroded  or  pitted  anode  rod  indicates  high 

water conductivity and should be checked and/or replaced more 

often than  an anode rod that appears to be intact. Replacement 

of a depleted anode rod can extend the life of your water heater. 

Inspection should be conducted by a qualified technician, and at 

a minimum should be checked annually after the warranty period.
Artificially softened water is exceedingly corrosive because the 

process substitutes sodium ions for magnesium and calcium ions.
The use of a water softener may decrease the life of the water 

heater tank.
The anode rod should be inspected after a maximum of three 

years and annually thereafter until the condition of the anode rod 

dictates its replacement. Anode rod replacement is not covered 

by warranty.
NOTE: Artificially softened water requires the anode rod to be 

inspected annually.
