ECO ® Tec series 2 gas-fired water boiler – boiler manual
Annual startup
The boiler should be inspected and
started annually, at the beginning of the
heating season, only by a qualified service
technician. In addition, the maintenance
and care of the boiler designated in
Figure 115, page 127 and explained on
the following pages must be performed
to assure maximum boiler efficiency and
reliability. Failure to service and maintain
the boiler and system could result in
equipment failure.
Electrical shock hazard — 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.
Address reported problems
Inspect any problems reported by owner and correct before
proceeding.
Inspect boiler area
1. Verify that boiler area is free of any combustible materials,
gasoline and other flammable vapors and liquids.
2. Verify that air intake area is free of any of the contaminants
listed on page 20 of this manual. 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 & jacket door
gaskets
1. Remove jacket door and inspect interior of boiler.
2. Visually inspect the jacket door gaskets on front of cabinet.
Make sure all are in good condition. Obtain replacements
if any gasket is damaged.
Jacket door gaskets must be intact, and must
provide a reliable seal. Replace any damaged
gasket.
3. Remove the venturi air inlet silencer and clean if necessary.
Reinstall silencer.
4. Vacuum any sediment from the inside of the boiler and
components. Remove any obstructions.
Do not use solvents to clean any of the boiler
components. The components could be damaged,
resulting in unreliable or unsafe operation.
