INSPECT BOILER AREA
1. Verify that boiler area is free of any combustible materials,
gasoline and other ammable vapors and liquids.
2. Verify that air intake area is free of any of the contaminants.
If any of these are present in the boiler intake air vicinity,
they must be removed. If they cannot be removed, reinstall
the air and vent lines per this manual.
Inspect boiler interior:
1. Remove the front access cover and inspect the interior of
the boiler.
2. Vacuum any sediment from inside the boiler and components.
Remove any obstructions.
GENERAL MAINTENANCE
This is a pre-mix burner system. The ame is not supposed to be
directly on the burner. The ame should be just above the burner
deck approximately 1/8” and blue in color, see Figure 77.
FIGURE 77. BURNER FLAMES
Visually check ame characteristics through the view port located
on the top head of the boiler. Figure 77 shows the normal ame
condition.
These boilers are designed to give many years of efcient and
satisfactory service when properly operated and maintained.
To assure continued good performance, the following
recommendations are made.
The area around the unit should be kept clean and free from lint
and debris. Sweeping the oor around the boiler should be done
carefully. This will reduce the dust and dirt which may enter the
burner and heat exchanger, causing improper combustion and
sooting.
MAIN BURNER
Check main burner every three months for proper ame
characteristics. The main burner should display the following
characteristics:
•Provide complete combustion of gas.
Cause rapid ignition and carry over of ame across entire burner.
Give reasonably quiet operation during initial ignition, operation
and extinction.
Cause no excessive lifting of flame from burner ports.
MAINTENANCE PROCEDURES
MAINTENANCE SCHEDULES
Yearly procedures for Service Technician:
Check for reported problems.
Check the interior; clean and vacuum if needed.
Clean the condensate trap and ll with fresh water.
Check for water/gas/ue/ condensate leaks.
Ensure ue and air lines in good condition and sealed
tight
Check system water pressure/system piping/expansion
tank
Check control settings.
Check spark igniter and ame sensors. Clear and clean
any deposits.
Check wiring and connections.
Perform start-up checkout and performance verication.
Flame inspection (stable, uniform)
Flame signal (at least 10 microamps at high re)
Clean the heat exchanger if ue temperature is more
than 54°F (30°C) above return water temperature.
Test low water ow conditions.
Clean the heat exchanger.
Remove and clean burner using compressed air.
Maintenance by Owner:
Daily:
Check boiler area .
Check pressure/temperature gauge.
Monthly:
Check vent piping.
Check air intake piping (Direct Vent).
Check air and vent termination screens.
Check relief valve.
Check condensate drain system.
Check automatic air vents .
Every 6 months:
Check boiler piping (gas and water) for leaks.
Check and operate the pressure relief valve.
End of season months:
Shut the boiler down (unless boiler used for domestic hot
water)
Make sure the maintenance of the boiler must be performed to
assure maximum boiler efciency and reliability. Failure to service
and maintain the boiler and system could result in equipment
failure.
Make sure to turn off power to the boiler before any service
operation on the boiler except as noted otherwise in this
instruction manual. Failure to turn off electrical power could result
in electrical shock, causing severe personal injury or death.
