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 ser-
vice 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 qual-
ified 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. Jaguar J-390 boiler may
be installed and vented either as direct-vent boiler, 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.

1. VENTING AND AIR INTAKE SYSTEM REGULAR
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, corro-
sion, 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 out-
side termination, louvers and screen should be checked for
any debris blocking the opening and cleaned as required.
