17.1. ServiceTechnician Maintenance Procedures
The INSTINCT must be inspected and serviced
annually, preferably at thestartoftheheating season,
by a qualified service technician. In addition, the
owner maintenance and care of the unit as outlined
in Chapter 16 on page 75 and further explained
in the INSTINCT User’s Information manual should
be performed to assure maximum efficiency and
reliability of the unit. Failure to service and maintain
the INSTINCT and the system components can
result in equipment failure, resulting in substantial
property damage, serious injury, or death.
NOTICE
The following information provides detailed
instructions for completing the service technician
maintenance items outlined in the maintenance
schedule of Chapter 16 on page 75.
17.2. Reported Problems
Any problems reported by the owner should be
checked, verified and corrected before proceeding
with any maintenance procedures.
17.3. Check Surrounding Area
• Verify that the area surrounding the INSTINCT is free
of combustible / flammable materials or flammable
vapors or liquids . R emo v e immediat ely if f ound .
• Verify that combustion air inlet area is free of any
contaminates. Refer to the materials listed in
Sec-
tion 2.1 on page 5 of this manual. If any of
these products are in the area from which the unit
takes its combustion air, they must be removed
immediately or the combustion air intake must be
relocated to another area.
17.4. Inspect Burner Area
• Remove the boiler front jacket panel and venturi inlet
elbo w .
• Vacuum any dirt or debris from the burner/blower
components
.
• Check the burner plate mounting nuts for tightness,
see Section 17.24 on page 80 for torque specification.
• Check burner plate gasket for discoloration or damage.
• Check for flue gas leakage where the condensate pan
connects to the heat exchanger and at the top and
bottom of the internal vent pipe.
• Re-install venturi inlet elbow and front jacket panel
when completed.
Do not use solvents to clean any of the burner
components. The components could be damaged,
resulting in unreliable or unsafe operation. Failure to
comply with this instruction can result in substantial
property damage, serious injury, or death.
17.5. Check System Piping
• Inspect all water and gas piping for leaks and verify
that the piping is pr oper ly suppor t ed .
• Inspect the fittings and components on the unit
and verify they are leak free.
Eliminate all system water leaks. Continual fresh
make-up water will reduce the heat exchanger life
causing boiler failure. Leaking water may also cause
severe property damage to the surrounding area.
Inspect the gas supply piping using the procedure
outlined in Section
on page 63. Failure to comply
with this instruction can result in substantial
property damage, serious injury, or death.

water as necessary to clean.
• Remove plastic ball and clean with fresh water.
• Check the drain piping from the condensate drain
assembly to the drain. Refer to Section
6.2 on page
27 . Flush to clean as necessary.
• Install the plastic ball into the condensate drain
assembly and reassemble onto the boiler by
tightening the retaining nut with rubber seal onto
the boiler. Hand tight only.
• Remove the fill plug on the condensate drain
assembly and fill with water. See Fig. 14 on page 28.
• Replace the fill plug on drain assembly.
