Jaguar Model J-390

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-390 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 (see Page 4). 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 6 may be used for the venting system installation. If stainless steel vent systems are used, follow the manufactur- er’s instructions, in conjunction with these instructions.

I.Non-Direct Vent Installation

The air for combustion is taken from the ambient air surrounding the boiler; therefore, ample supply of air is required for combustion and ventilation (see page 6.)

DO NOT use this installation method if the surrounding of the boiler is contaminated. See page 5 for the list of harmful contaminants and their sources, to avoid.

A. SIDEWALL VENTING - NON-DIRECT VENT

Figures 6 and 7 show typical horizontal sidewall venting. For combustible wall passage of vent piping, a UL listed thimble or flashing and sealing boot must be used, providing the wall thickness from 3" minimum up to 14" maximum. The vent piping must terminate with a screened tee or elbow termination facing down.

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 4 feet below,

4 feet horizontally from, or 1 foot above 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 equip- ment. 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 overhang or deck. Vent termination should not allow flue gas discharge towards neighbor’s windows or where personal injury or property damages can occur.

B. NON-DIRECT VENT - VERTICAL VENTING

Figure 8 shows typical venting through the roof. The vent pipe must pass through the ceiling, floor and the roof vertically through a 8" minimum diameter 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 (see Figure 9) 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 termina- tion 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 5). Piping the air intake to the outside can prevent contaminants from the boiler surrounding from entering the combustion air supply.

A. SIDEWALL DIRECT VENTING

Figures 10 and 11 show typical sidewall direct venting, using a Slant/Fin vent/air intake termination.

CAUTION: Flue gasses existing from the vent terminal will con- dense. Building materials in the area of the terminal should be protected from discoloration and degradation, in addition to the requirements of the vent termination location and clearances stated in this manual.
