1. Burner Inspection.
Clean the main burners and air louvers of dust, lint
and debris. With burner in operation, make a visual
check of the burner flame and the pilot flame (when
equipped). Yellow flames indicate some restriction of
combustion air openings. A bright orange, luminous
flame is not normal and can cause sooting under
prolonged operation. Should this condition be ob-
served, contact immediately a qualified service agency
to correct the problem.
2. Venting System Inspection.
Visually inspect the venting system. Make sure the
vent connections are secure and have not become
disengaged. Look for any indication of corrosion, or
carbon (soot) streaks which could cause leakage of
products of combustion into the living space. Inspect
the vent terminal outside the building. Make sure it is
not damaged to cause blockage or restriction of the flue
gas. Observe for any indication of soot. The presence
of soot accumulation in the vent terminal would indicate
an abnormal operating condition. This should be
investigated and corrected by a qualified service
agency.

3. Circulator (Water Pump) Inspection.
The circulator is permanently lubricated and thus,
will not require any lubrication. Inspect for evidence of
water leakage. This should be corrected to prevent any
possible damage to electrical components of the boiler.
CAUTION:
In case of a prolonged power failure during
freezing weather conditions, boiler and piping system
must be drained completely to avoid possible damage
to the heating system.
To prevent the potential freezing damage to the
heating system, it is recommended that the following
system shut down procedure be performed.
SYSTEM SHUT DOWN PROCEDURE
1. Set the room thermostat to "OFF" or the lowest
setting.
2. Turn off all electric switches to the boiler.
3. Turn off all gas valves supplying gas to the boiler.
Refer to operating instruction label on the boiler.
4. Shut off the water supply to the boiler piping system
loop.
5. Open drain valve on the boiler to remove water
from the boiler and the piping circuits.
NOTE:
It may be necessary to open the purge valves
and/or manual air vents to facilitate complete drainage
of water from the heating system.
4. Service Assistance.
If service is required on the boiler, contact your
local service agency or Raypak, Inc. can refer you to the
proper qualified service agency. It is important and very
often will save time if you state the model number, serial
number and type of gas used. This information will be
found on the nameplate of the boiler.
