In unusually dirty or dusty conditions, care must be taken to keep
boiler cabinet door in place at all times. Failure to do so VOIDS the
warranty.
Allowing the boiler to operate with a dirty combustion chamber
will hurt operation. Failure to clean the heat exchanger as needed
by the installation location could result in boiler failure, property
damage, personal injury, or death. Such product failures ARE NOT
covered under warranty.
Check all piping and gas connections.
Verify all are tight.
Pressurize system (12 - 15 psi).
Add water to prime condensate cup.
Verify near boiler piping is properly
supported.
Percentage of glycol in system (0 -
50%)
Leak test using locally approved meth-
ods (consult jurisdictional code book).
Check incoming gas pressure (3.5 to 14"
WC).
Check the "drop" on light off (less than 1"
WC).
Check and adjust (if necessary) carbon
dioxide content.
Check and adjust (if necessary) carbon
monoxide content.
Ensure all electrical connections of line
voltage (pumps, etc.) and low voltage
circuits (system sensor, outdoor sensor,
etc.) are properly wired.
Turn up thermostat to verify wiring
connections.
Check uA reading in the status menu (see
Start-Up section, this manual).
Verify system settings.
Verify safety and operation of the indirect
water heater. Record settings.
If necessary, convert the boiler to the
proper fuel type.
Locate the stickers in the appropriate
locations on the boiler.
Verify combustion settings after gas
conversion - Carbon Dioxide.
Verify combustion settings after gas
conversion - Carbon Monoxide.
Mail in conversion registration.

The boiler requires minimal periodic maintenance under normal
conditions. However, in unusually dirty or dusty conditions, periodic
vacuuming of the cover to maintain visibility of the display and
indicators is recommended.
Periodic maintenance should be performed once a year by a qualified
service technician to assure that all the equipment is operating safely
and efficiently. The owner should make necessary arrangements with
a qualified heating contractor for periodic maintenance of the boiler.
Installer must also inform the owner that the lack of proper care and
maintenance of the boiler may result in a hazardous condition.
