of reliable comfort and trouble-free performance.

The care and maintenance of your new boiler is important to
prevent a hazardous condition which might result form lack
of proper servicing. Therefore, you should perform regular
“owner” inspections as described in this manual (and report
any concerns to a qualified service technician) as well as
have your boiler serviced by a qualified service technician at
least once a year, preferably before the beginning of each
heating season.

LIGHTING INSTRUCTIONS

Locate, read and then follow the procedures on the lighting
instructions label attached to the boiler. For reference, we
have reproduced those instructions in this manual.

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. Lynx 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,
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.
