INSPECTION
Your boiler and heating system will last an indefinitely long
time at full efficiency, if it is inspected regularly and is kept
in good repair and adjustment. You, the user, should make
regular inspections, and report any problems to your
service agency. At regular intervals, you should have that
agency inspect the system and make repair adjustments as
necessary. What you and the service agency should do is
listed below. Contact your gas supplier for a list of qualified
service and repair agencies.
USER INSPECTION
The user should make the following inspections at least
once each month during the heating season and once just
before cold weather starts. Bobcat B-120 and B-200 boil-
ers may be installed and vented either as direct-vent boil-
er, which all air for combustion is obtained directly from
outside through the air intake piping or as non-direct-
vent boiler, which all air for combustion is taken from
inside the boiler room. Typical direct-vent installations are
shown on Figures 2 and 3. Non-direct-vent installation is
shown on Figures 4, 5 and 6.

INSPECTION
Inspect the system regularly for condensation, corrosion,
sagging and/or physical damage. A qualified professional
should service the boiler annually and include such an
inspection at that time. The homeowner should look over the
system monthly for damage, water stains, any signs of rust,
other corrosions or separation of the vent and air intake
piping (if direct-vent).
Should an inspection turn up signs of condensation,
corrosion, sagging or damage, the boiler should be shut
down immediately and the condition should be corrected by
a qualified professional.
If the boiler is vented horizontally through the wall, the
outside termination, louvers and screen should be checked
for any debris blocking the opening and cleaned as
required.
