B. Qualified Service Technician
The following maintenance should be performed by a qualified service
technician annually:
General
• Attend to any reported problems.
• Inspect the interior of the boiler cabinet area; clean and vacuum if
necessary.
• Clean the condensate trap and fill with fresh water.
• If applicable, check the condensate neutralizer and ensure it is full
of condensate neutralizing marble chips.
• Check for leaks: Water, gas, flue, and condensate.
• Verify exhaust vent and intake piping are in good condition and
sealed tight.
• Check exhaust vent and intake pipe bracing. Ensure bracing is
undamaged and in good condition.
• Check boiler water pressure, piping, and expansion tank.
• Check control settings.
• Check ignition electrode. Sand off any white oxide. Clean and
reposition.
• Check ignition and ground wiring.
• Check all control wiring and connections.
• Check burner flame pattern (stable and uniform).
Additional Items if Combustion or Performance is Poor
• Ensure boiler is connected to the proper gas type.
• Ensure boiler is connected to proper electrical power supply.
• Check the water valves and gas shut-off valve. Ensure all are fully
open.
• Clean heat exchanger and flue ways.
• Remove burner assembly and clean burner head using compressed
air only.
The qualified service technician should review service with the owner
after the maintenance items are completed.
A. Owner Maintenance
Periodically
• Check area around the boiler.
• Check and remove any blockage from the outdoor exhaust vent
and intake pipe terminations. DO NOT perform this maintenance
if exhaust vent and intake pipe terminations are in difficult to reach
locations.
• Check the CH loop pressure gauge. Normal CH pressure will range
from 15 - 30 psi.
Monthly
• VERY IMPORTANT: Check / test carbon monoxide detectors to
ensure proper operation per the manufacturer’s instructions.
• Check exhaust vent and intake piping.
• Check exhaust vent and intake pipe bracing. Ensure bracing is
undamaged and in good condition.
• Check the pressure relief valve.
• Check the condensate drain system.
• If applicable, check the condensate neutralizer and ensure it is full
of condensate neutralizing marble chips.
Every 6 Months
Check boiler piping and gas supply piping for corrosion or signs of
potential leakage.
WARNING
WARNING
Important
Contact a qualied service technician for assistance if a Lockout
Error occurs frequently. Repeated Lockout Error conditions could
indicate a serious error with the boiler or installation. Failure to
contact a qualied service technician to troubleshoot the error could
result in substantial property damage, serious personal injury, or
death.
If the boiler signals the error again after a reset, turn off the boiler.
Move the external electric switch to the OFF position. Close the gas
valve and contact a qualied service technician.
DO NOT attempt to repair or service this boiler. Contact a qualied
service technician if the boiler needs repair or maintenance. Ask
your gas supplier for a list of qualied service providers.
Ensure each zone valve connected to the boiler is open while
the boiler is operating. Doing so ensures proper heating system
operation.
DO NOT wipe the boiler or control panel with a wet cloth. Doing
so may result in an electric shock, substantial property damage,
premature boiler failure, severe personal injury, or death.
Be careful when opening a hot water faucet or draining water from
the boiler. Water temperature over 125oF can instantly cause
severe burns, or death, from scalds. Children, disabled, and elderly
are at the highest risk of being scalded. See instruction manual
before setting temperature at boiler. Feel water before bathing or
showering!
