2. CONDENSATE REMOVAL SYSTEM
The Bobcat B-120 and B-200 boilers are equipped with
a built-in condensation drain and trap. The trap must be
filled with water. DO NOT operate the boiler without fill-
ing the trap with water to prevent flue gas discharge into
space. Periodic inspection should be made of this
assembly for deterioration of the tubing and to insure
that the trap is not plugged. If it is plugged or appears to
have excessive sediment in it, it should be removed
from the drain assembly, straightened out to clear the
obstruction, reformed, filled with water and reinstalled
as before. (See Figure 7).
Leave the top of the condensate drain tee open, to act
as a vacuum breaker. Do not allow any part of the
condensate removal system to be exposed to freezing
temperatures, or any other conditions that could cause
blockage.
If a neutralizing system is installed, the filter medium will
require periodic changing, to ensure it's effectiveness.
Refer to the neutralizing unit's manufacturers instruc-
tions, if available, or change the medium on an annual
basis.
3. PIPING INSPECTION
Look at all water piping. There should be no leaks or
signs of leaks at any pipe joints or around the boiler.
4. SYSTEM WATER PRESSURE INSPECTION
The boiler water pressure is indicated on the pressure
gage (See Figure 1 for location). The boiler water outlet
temperature is normally indicated on the temperature
display (See Figure 1 for location and Figure 9 for digits
illustration). For most installations, it should indicate

about 12 to 15 psi pressure when temperature is about
70 to 100F and from 15 psi to 25 psi when temperature
is up to 195˚F. FOR YOUR SYSTEM, there is one
correct pressure for each temperature. ASK YOUR
INSTALLER OR SERVICEPERSON TO EXPLAIN AND
SHOW YOU. Learn what normal pressure to look for. If
pressure increases from normal, the relief valve will
open to relieve the pressure. Call your service organiza-
tion if pressures are higher or lower than normal, and if
the relief valve spills water. Repair or adjustment is
needed.
5. UNUSUAL NOISE
Stand near the boiler and look and listen. As the burner
start and shut off, there should be no unusual noise.
6. BOILER ROOM AIR SUPPLY
Ample boiler room fresh air is required for combustion
(non-direct vent installation) and ventilation (direct-vent
installation).
Check air vents for continues positive supply of air as
required. Air needs are greatest in cold weather if boiler
installation is non-direct vent method. Air vents must be
open and free of obstruction.
Warning:
The flow of combustion and ventilating air to the
boiler should not be obstructed.
Warning:
If you find any problem during your inspection, call
for service immediately.
