Start-Up, Adjust, and Test
Has the boiler been started?
If necessary, has the boiler gas valve been adjusted?
Has the installation been customized per installation location requirements?
Have all customized system parameters been tested?
Has proper boiler operation been confirmed?
Burner Flame
Has the burner flame been checked?
Have combustion values been verified with a calibrated combustion analyzer?
If the flame does not appear normal, it may need to be cleaned by a qualified service technician. See Figure 53 for
flame sight glass window location.

Part 13 - Maintenance

DANGER
!
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.
Check the Surrounding Area
DANGER
!
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 contaminates are found:
Remove products immediately from area.
If contaminates 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.
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 Contaminates
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
contaminates and areas likely to have these contaminates in Table
7. If any of these contaminates 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.
Ensure the Boiler Cabinet is Closed
Ensure the boiler cabinet is closed. Tighten the two upper and lower
screws to secure it. The cabinet must be closed while the boiler is
running.

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 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 and DHW Pressure Gauges
Ensure the pressure reading on the CH gauge does not exceed
30 psig. Higher pressure readings may indicate a problem with
the expansion tank.
Ensure the pressure reading on the DHW gauge does not
exceed 150 psig. Higher pressure readings may indicate a
problem with the domestic expansion tank.
Contact a qualified service technician if problem persists.
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.
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.
Check Pressure Relief Valve
Visually inspect the primary pressure relief valve and discharge
pipe for signs of weeping or leakage.
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.
Check the Condensate Drain System
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.
