Crown Boiler BWF162 Manual De Usuario

12) Location of Horizontal Vent Terminal – Observe the following limitations on the terminal location:

• Terminal must be at least 4 feet below or 4 feet horizontally from any window, door, or gravity air inlet into the

building (Fig. 10).

• The bottom of the terminal must be at least 12” above the normal snow line. In no case should it be less than 12”

above grade level (Fig 10).

• The bottom of the terminal must be at least 7 feet above a public walkway.

• The bottom of the terminal must be at least 3 feet above any forced air inlet located within 10 feet.

• A clearance of at least 4 feet horizontally or 4 feet vertically must be maintained between the terminal and gas meters,

electric meters, regulators, and relief equipment.

• Do not locate the terminal under decks or similar structures.

• Top of terminal must be at least 4 feet below eves, soffits, or overhangs. Overhang may not exceed 3 feet (Fig. 12).

Do not use the Tee terminal under an overhang deeper than 6”.

• Terminal must be at least 3 feet from an inside corner.

• Under certain conditions, water in the flue gas may condense on the structure in areas around the terminal. If these

areas are made of materials subject to damage by flue gas condensate, they should be protected.

• If possible, install the terminal on a wall away from the prevailing wind. Reliable operation of this boiler cannot be

guaranteed if the terminal is subjected to winds in excess of 40 mph.

• The noise level in the vicinity of the terminal is approximately 65 dB (roughly the level of a normal conversation).

Care should be taken when the terminal is positioned in areas where this might be objectionable, such as near
bedroom windows.
