Jaguar Caravan Multiple and Cascading Boilers 8
VENT AND AIR INTAKE RESTRICTIONS
1. Maximum allowed equivalent vent and air intake length for all of
the approved vent and air intake materials is 100 equivalent feet.
2. Equivalent of vent or air intake length is sum of the straight pipe
lengths and equivalent length of elbows. Each 90˚ elbow is equivalent
to 10 ft. of 4" pipe.
3. The vent termination is in addition to the allowed equivalent lengths.
4. Minimum vent length is 2 feet of straight pipe, plus one 90˚ elbow.
5. Vent length restriction is for both direct and non-direct vent installations.
EXAMPLE: The combustion air is provided by air intake piping directly
to the boiler (direct-vent installation). The vent piping will be PVC and
installation location will require the use of 4 elbows for the vent to run
the termination. The air intake piping will also be PVC, and also will
require the use of 4 elbows.
In this case, the maximum straight pipe vent length that can be utilized
with the 4 elbows would be: 100’ - (4’ x 10’) = 60’. Since the air intake
pipe also is PVC and requires the use of 4 elbows, the maximum
straight pipe air intake length that can be utilized is also 60 feet.
If the air for combustion were taken from the boiler room (non-direct vent
installation), still the maximum straight vent length would be 60 feet.
6. The Jaguar J-390C boiler is equipped with a built-in condensation
drain and trap system. The traps must be filled with water. DO NOT
operate the boiler without filling the trap with water to prevent flue gas
discharge into space. The drain must dispose of possibly large
quantities of condensate, which may require a neutralizing system.
Refer to the “Condensate Drainage” section of this manual. No
additional condensation drain and trap is required on the vent piping
system itself.
7. The horizontal vent pipe must be sloped upward from the boiler at a
pitch of at least 1/4” per 1 foot of run, so that the condensate from the
vent system runs to the boiler vent adapter pipe, then out the built-in
condensation drain and trap.
8. The horizontal vent and air intake pipes must be supported with pipe
straps, at intervals no greater than 5 feet, when PVC/CPVC pipe is
utilized. This support spacing applies also to stainless steel vent pipe,
unless the manufacturer’s instructions permit otherwise. The vertical
vent and air intake pipes also must be supported, wherever the
building construction provides allowance for it, such as ceiling or
roof passage openings where a firestop and support or
braces can be affixed.
9. Minimum clearances of vent pipes from combustible constructions
must be maintained (Pub J-40). No clearance is required between the
vent and air intake pipes of this boiler.
10. Common venting with other appliances or another Jaguar boiler is
not allowed.
11. DO NOT install a vent damper or similar devices in vent system or on
the boiler.
12. DO NOT insulate venting system.
VENTING INSTALLATION
Only PVC/CPVC and approved stainless steel materials listed on page 7
may be used for the venting system installation. If stainless steel vent sys-
tems are used, follow the manufacturer’s instructions, in conjunction with
these instructions.
I. Non-Direct Vent Installation
The air for combustion is taken from the ambient air surrounding the boil-
er; therefore, ample supply of air is required for combustion and ventila-
tion (see page 6.)
DO NOT use this installation method if the surrounding of the boiler is
contaminated. See page 6 for the list of harmful contaminants and their
sources, to avoid.
CAUTION: Flue gasses exiting from the vent terminal will condense.
Building materials in the area of the vent terminal should be protected
from discoloration and degradation.
VENT TERMINATION LOCATION AND CLEARANCES
1. The venting system shall terminate at least 3 feet above any forced
air inlet located within 10 feet.
2. The venting system shall terminate at least 12 inches below, or 12
inches horizontally from any door, window or gravity air inlet into
any building. The bottom of the vent terminal or air intake terminal
shall be at least 12 inches above grade or the normal snow level
whichever is greater.
3. Through the wall vents shall not terminate over public walkways or
over areas where condensate or vapor could create a nuisance or
hazard or could be detrimental to the operation of regulators, relief
valves or other equipment. Minimum clearance of 4 feet horizontal
distance is maintained, from electric meters, gas meters, regulators
and relief equipment.
4. Vent termination must not be located in any confined space (i.e.
window wells, alcoves, narrow alleys) or under any over hang or deck.
Vent termination should not allow flue gas discharge towards neigh-
bor’s windows or where personal injury or property damages can occur.
A. NON-DIRECT VENT - VERTICAL VENTING
Figure shows typical venting through the roof. The vent pipe must pass
through the ceiling, floor and the roof vertically through a 8" minimum diam-
eter cutout. A fire stop is required for each ceiling and floor penetration. For
roof passage, an appropriate UL listed roof flashing must be used.
An existing chimney may be used as a chase for vertical venting. Other
appliances CANNOT be vented into the same chimney or vent pipe with in
the chimney.
The vertical vent piping must terminate with a screened tee, combination of
45˚ elbow and a 90˚ screened elbow termination or a rain cap termination.
II. Direct Vent Installation
Air intake piping from outside to the boiler air intake adapter provides the
air for combustion. The boiler surrounding may be contaminated (See
page 6). Piping the air intake to the outside can prevent contaminants
from the boiler surrounding from entering the combustion air supply.
B. SIDEWALL DIRECT VENTING
Vent termination location and clearances for non-direct vent stated
in paragraph I, also applies to sidewall direct venting.
• See figure 4, 5 & 6 for direct vent side wall venting using the
Slant/Fin vent/air intake termination.
• See figure 6 for direct vent side wall venting with close spacing.
• See figure 7 & 8 for direct vent through the roof.
CAUTION: Flue gasses existing from the vent terminal will condense.
Building materials in the area of the terminal should be protected from
discoloration and degradation.
