MAINTENANCE PROCEDURES
The MODULATING DELTA should be
inspected and serviced annually, prefer-
ably at the start of the heating season, by
a qualified service technician. In addi-
tion, the maintenance and care of the
appliance as outlined on page 48 and
further explained on pages 49 through
53 should be performed to assure maxi-
mum efficiency and reliability of the
appliance. Failure to service and main-
tain the MODULATING DELTA and
the system components could result in
equipment failure, causing possible
severe personal injury, death or substan-
tial property damage.
The following information provides
detailed instruction for completing the
maintenance items outline in the mainte-
nance schedule on page 48. In addition
to this maintenance, the MODULAT-
ING DELTA should be serviced at the
beginning of the heating season by a
qualified service technician.
Reported Problems
Any problems reported by the owner
should be checked, verified and corrected
before proceeding with any maintenance
procedures.
Check Surrounding Area
Verify that the area surrounding the MOD-
ULATING DELTA is free of combustible /
flammable materials or flammable vapors
or liquids. Remove immediately if found.
Refer to the list of potential materials listed
in the MODULATING DELTA Vent
Supplement. If any of these products are in
the room from which the appliance takes its
combustion air, they must be removed
immediately or the combustion air intake
must be relocated to another area.
Inspect Burner Area
Remove the burner hood and inspect the
appearance of the burner components.
Vacuum any dirt or debris from the burner
components.
Remove the venturi inlet elbow to check for
dirt and debris. Remove any obstructions.
Do not use solvents to clean any of the
burner components. The components
could be damaged, resulting in unreli-
able or unsafe operation.
Check System (Primary and Domestic)
Piping
Inspect all piping on the Primary Heating
system and the Domestic system for leaks
and verify that the piping is leak free.
Inspect the fittings and components on the
appliance and verify they are leak free.
Eliminate all primary water system leaks.
Continual fresh make-up water will
reduce the outer tank life causing tank
failure. Leaking water may also cause
severe property damage to the surround-
ing area.
