Part 14 - Maintenance
A. Procedures
Periodic maintenance should be performed once a year by a qualified
service technician to ensure 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.
The installer must also inform the owner that a lack of proper care and
maintenance of the boiler may result in a hazardous condition.
Check the Surrounding Area
Ensure the Cabinet is Closed When the Boiler is Operating
The boiler cabinet must be closed when the boiler is operating.
Combustible/Flammable Materials
Do not store combustible materials, gasoline, or other flammable
vapors or liquids near the boiler. If found, remove these materials
immediately.
Air Contaminants
If allowed to contaminate combustion air, products containing chlorine
or fluorine will produce acidic condensate that will cause significant
damage to the boiler. Read the list of potential contaminants and areas
likely to have these contaminants in Table 7. 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 and the main power line are properly
connected to the manual switch box inside the boiler.
Check the Status of the Control Panel
Observe the Control Panel to ensure the boiler is powered on and to
check for any error codes. Clear any debris from the panel.
Check CH Pressure Gauge
Ensure the pressure reading on the CH gauge does not exceed 30 psig.
Higher pressure readings may indicate a problem with the expansion
tank. Immediately contact a qualified service technician to inspect the
boiler and system.
B. Maintenance That May be Performed by the User
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 or intake pipe openings. If removing the debris does not allow the
boiler to operate correctly, contact your qualified service technician to
inspect the boiler and the vent system.
Check Exhaust Vent and Intake Piping
Visually inspect the exhaust vent for any signs of blockage, leakage, or
deterioration of the piping. Inspect the exhaust vent bracing. Ensure
bracing is undamaged and in good condition. Notify a qualified service
technician immediately if any problems are found.
Check Pressure Relief Valve
1. Visually inspect the primary pressure relief valve and discharge pipe
for signs of weeping or leakage.
2. If the pressure relief valve often weeps, the expansion tank may
not be operating properly. Immediately contact a qualified service
technician to inspect the boiler and system.
Operate Pressure Relief Valve
1. Before proceeding, verify that the relief valve outlet has been piped
to a safe place of discharge, avoiding any possibility of scalding
from hot water.
2. Shut power off to the boiler. To avoid scalding, wait for boiler to cool
before operating the relief valve.
3. Lift the relief valve lever. If water flows freely, release the lever and
allow the valve to seat. Watch the end of the relief valve discharge
pipe to ensure that the valve does not weep after the line has had
time to drain. If the valve weeps, lift the lever again to attempt
to clean the valve seat. If the valve does not properly seat and
continues to weep, contact a qualified service technician to inspect
the valve and system.
4. If water does not flow from the valve when you completely lift the
lever, the valve or discharge line may be blocked. Immediately shut
the boiler down per instructions on page 2 and call a qualified
service technician to inspect the valve and system.
5. If relief valve seats properly, restore power to the boiler. Observe
operation for five minutes and ensure it operates properly.
WARNING
WARNING
The boiler must be inspected and serviced annually,
preferably at the start of the heating season, by a qualified
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 efficiency 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.
To prevent the potential of substantial property damage, severe
personal injury, or death, eliminate all the materials listed in
Table 7 from the area surrounding the boiler and the vicinity of
the combustion air intake. If contaminants are found:
• Remove products immediately from area.
• If contaminants have been there for an extended period,
call a qualified service technician to inspect the boiler for
possible damage from acid corrosion.
If products cannot be removed, immediately call a qualified
service technician to re-pipe the combustion air intake piping
away from the contaminated areas.
Failure to inspect the venting system and have it repaired
by a qualified service technician can result in vent system
failure, causing severe personal injury or death.
To avoid water damage or scalding due to relief valve
operation, a discharge line must be connected to the
valve outlet and directed to a safe place of disposal. This
discharge line must be installed by a qualified service
technician in accordance with the boiler installation manual.
The discharge line must be terminated so as to eliminate
possibility of severe burns or property damage should the
valve discharge.
DANGER
DANGER
Check the Condensate Drain System
1. While the boiler is running, check the discharge end of the
condensate drain tubing. Ensure no flue gas is leaking from the
condensate drain tubing by holding your fingers near the opening.
2. If you notice flue gas leaking from the opening, this indicates a
dry condensate drain trap. If problem persists, contact a qualified
service technician to inspect the boiler, condensate line and
condensate trap.
