HORIZONTAL VENT THROUGH A SIDE WALL: (Vertical vent through roof is on page 23)

 Refer to General Venting Requirements on page 19

 Minimum length of a horizontal side-wall vent:

 Regardless if a 90° elbow is installed, a Minimum linear 36 inch (3 ft; 91 cm) single

wall ‘C’ vent plus minimum 12 inch (30.5 cm) double wall ‘B’ vent through wall

 Total minimum linear vent length of 48 inches (4 ft; 122 cm)

 Maximum length of a horizontal side-wall vent:

 Total Maximum vent length is 15 ft (4.6 m)

 Each 90° or 45° elbow is equivalent to 5 ft

 A minimum 12 inch (30.5 cm) double wall ‘B’ vent must be used through the wall

 The flue vent system must slope downwards approximately 1/4" per foot (63 mm / 300 mm)

toward the vent terminal, from the termination of the tube - radiant tube must be level.

 A maximum of two elbows (90° or 45°; each = equivalent 5 ft) can be installed in a horizon-

tal vent

 For side wall venting use either Schwank/InfraSave 4” (10 cm) horizontal vent terminal (Part

Number: JA-0528-XX - available as an option) or an approved 4” (10 cm) “High Wind” vent

termination cap (see clearance information previous page and next page)

 Install the termination cap a minimum of 6 inches (15 cm) from the outside wall to the inside

edge of terminal opening to minimize back pressure caused by turbulent wind conditions

(See Fig. 9 above). This also ensures flue gases are directed away from the structure to

help protect building materials from degradation by the exhausted flue gases.

 The vent must be installed to prevent blockage by snow, undue wind pressure on the termi-

nation, and to protect building materials from degradation by flue gases.
