3.2.3

Check Temperature Display and Pressure Gauge

• Ensure the pressure reading on the pressure gauge
does not exceed 25 psig. Higher pressure readings
may indicate a problem with the expansion tank.
• Ensure the temperature on the display panel does
not exceed 194ºF. Higher temperature readings
may indicate a water flow problem.
• Contact a qualified service technician if problem
persists.
WARNING

Monthly Maintenance

3.3.1 Check Vent and Combustion Air Piping

• Visually inspect the venting system and combus-
tion air piping for blockage, deterioration of gas-
kets or leakage. Contact a qualified service techni-
cian immediately if any problems are found.
WARNING
In the case of In-direct vent installation the air
openings provided by the installer to supply
ventilation and combustion air are essential
for safe operation of the appliance. The user
must respect the importance of these air
openings and ensure that they are not partial-
ly or fully blocked under any condition. Fail-
ure to ensure free uncontaminated air flow
through the openings can result in substantial
property damage, serious injury, or death.
DANGER
Failure to inspect the vent system and com-
bustion air inlet piping and to have any con-
ditions repaired, will result in serious injury,
or death.

3.3.2 Check Pressure Relief Valve

1. Visually inspect the pressure relief valve and the
relief valve discharge pipe for signs of weeping or
leakage.
2. If the pressure relief valve weeps often, the expan-
sion tank may not be operating properly. Immedi-
ately contact a qualified service technician to in-
spect the unit and system.
