WELCOME TO OUR VALUED CUSTOMER

You are now the owner of a Slant/Fin Jaguar gas-fired boiler,
another quality heating product designed and manufactured
by an industry leader, to provide your family with many years
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

y concerns to a qualified service technician) as well as

an

our boiler serviced by a qualified service technician at

e y

hav
least once a y
heating season.

LIGHTING INSTRUCTIONS

DO NOT use this boiler if any part has been

underwater. Immediately call a qualified service

technician to inspect the boiler and to replace

any part of the control system and any gas

control which has been underwater.

WARNING

Should overheating occur or the gas supply

fail to shut off, DO NOT turn off or disconnect

NSPECTION

I

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

egular inspections, and report any problems to your

r

ervice agency. At regular intervals, you should have that

s

gency inspect the system and make repair adjustments as

a
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. 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-direct­vent 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.

. VENTING AND AIR INTAKE SYSTEM REGULAR

1

NSPECTION

I

Inspect the system regularly for condensation, corrosion,
sagging and/or physical damage. A qualified professional

hould service the boiler annually and include such an

s

nspection at that time. The homeowner should look over the

i

ystem monthly for damage, water stains, any signs of rust,

s
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.

2. CONDENSATE REMOVAL SYSTEM

The Jaguar boilers is equipped with a built-in conden­sation 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 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 an
b

lockage.

If a neutralizing system is installed, the filter medium will
require periodic changing, to ensure it’s effectiveness.

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

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 organiza­tion if pressures are higher or lower than normal, and if
the relief valve spills water. Repair or adjustment is
needed.

Stand near the boiler and look and listen. As the burner
start and shut off, there should be no unusual noise.

INTEGRATED BOILER CONTROL

The integrated boiler control monitors the status of the
room thermostat, high limit switch, low water cutoff (if
installed), water inlet and outlet sensors, flue gas sensor
and flame sensor. It controls the operation of the circula­tor, combustion blower, gas valve and spark ignitor. The
boiler control also determines the sequence of operation
and timing for pre and post purge periods, trial for ignition
and lock out.

The control display board provides information on boiler
operation on a mode and temperature display and can be
viewed, programmed and reset with specific push buttons.
Diagnostic information is also provided on the display, to
help determine the cause of boiler failure. (See Figure 9).

along with an error code in the temperature display.
Do not attempt performing any service under these
conditions, but do note the mode and temperature dis­play indication, in case the problem clears itself. An “A”
indication error can be cleared by pressing the reset
button once, which will allow re-try of operation. Do not
repeatedly press the reset button in this case, or if an
“E” or “H” indication error is displayed. Call a trained,
experienced service technician to troubleshoot and cor­rect the problem. The Jaguar Installation and Operating
