B. Qualied Service Technician
The following maintenance should be performed by a qualied 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 ll with fresh water.
• If applicable, check the condensate neutralizer and ensure it is full
of condensate neutralizing marble chips.
• Check for leaks: Water, gas, ue, 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 o any white oxide. Clean and
reposition.
• Check ignition and ground wiring.
• Check all control wiring and connections.
• Check burner ame 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-o valve. Ensure all are fully
open.
• Clean heat exchanger and ue ways.
• Remove burner assembly and clean burner head using
compressed air only.
The qualied service technician should review service with the owner
after the maintenance items are completed.
Part 4 - Maintenance Procedures
DANGER
!
The boiler must be inspected and serviced annually, preferably at
the start of the heating season, by a qualied service technician. In
addition, the maintenance and care of the boiler as outlined in this
manual must be performed by the user/owner to assure maximum
eciency and reliability. Follow the maintenance procedures
given throughout this manual. Failure to perform the service and
maintenance or follow the directions in this manual could damage
the boiler or system components, resulting in substantial property
damage, severe personal injury, or death.
Check the Surrounding Area
A. Daily Maintenance - To Be Performed by Owner
DANGER
!
To prevent the potential of substantial property damage, severe
personal injury, or death, eliminate the materials listed in Table
1 from the area surrounding the boiler and the vicinity of the
combustion air intake. If contaminants are found:
• Remove products immediately from the area.
• If contaminants have been there for an extended period, call
a qualied service technician to inspect the boiler for possible
damage from acid corrosion.
If products cannot be removed, immediately call a qualied
service technician to re-pipe the combustion air intake piping
away from the contaminated areas.
Combustible/Flammable Materials
Do not store combustible materials, gasoline, or other ammable
vapors or liquids near the boiler. If found, remove these materials
immediately.
Air Contaminants
If allowed to contaminate combustion air, products containing
chlorine or uorine will produce acidic condensate that will
cause signicant damage to the boiler. Read the list of potential
contaminants and areas likely to have these contaminants in Table
1. If any of these contaminants are in the room where the boiler is
located, or combustion air is taken from one of the areas listed, the
contaminants must be removed immediately or the intake pipe
must be relocated to another area.
Check the Power Source
Make sure the power cord is properly connected. The main power
line is connected to the manual switch box inside the boiler.
Check the Status of the Display Panel
Observe the Display Panel to ensure the boiler is powered on and
check for any error codes. Clear any debris from the panel.
Check Exhaust Vent and Intake Pipe Terminations
Verify that the boiler exhaust vent and intake pipe terminations are
clean and free of obstructions. Remove any debris from the exhaust
vent and intake pipe openings. If removing the debris does not
allow the boiler to operate correctly, contact your qualied service
technician to inspect the boiler and the vent system.
Ensure the Boiler Cabinet is Closed
Ensure the boiler cabinet is closed. The cabinet must be closed while
the boiler is running.
Check Pressure Gauge
• Check the CH loop pressure gauge.
• Normal CH pressure will range from 15 - 30 psi.
• Boiler may not operate if pressure is lower than 15 psi.
• Higher pressure readings may indicate a problem with the
Part 3 - Maintenance Schedule
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 dicult 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.
