2. CONDENSATE REMOVAL SYSTEM
The Jaguar boilers are equipped with a built-in conden-
sation drain and trap. The trap must be filled with water.
DO NOT operate the boiler without filling the trap with
water to prevent flue gas discharge into space. Periodic
inspection should be made of this assembly for deterio-
ration 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 effective-
ness. Refer to the neutralizing unit's manufacturers
instructions, 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
gauge (See Figure 1 for location). The boiler water out-
let temperature is normally indicated on the tempera-
ture display (See Figure 1 for location and Figure 9 for
digits illustration). For most installations, it should
PLASTIC TUBING
indicate about 83 to 103 kPa (12 to 15 psi) pressure
when temperature is about 21° to 38°C (70° to 100°F)
and from 103 to 172 kPa (15 psi to 25 psi) when tem-
perature is up to 91°C (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 pres-
sure to look for. If pressure increases from normal, the
relief valve will open to relieve the pressure. Call your
service organization 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
starts and shuts 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 continuous 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:
boiler should not be obstructed.
Warning:
for service immediately.
