NOTES:
(1)The horizontal run of vent pipe must be level and should have a 1⁄4” rise for every one foot of run towards the termination. Never allow the vent to run downward. This could cause high temperature and may present the possibility of a fire.
(2)The location of the horizontal vent termination on the exterior wall must not be easily blocked or obstructed. Refer
to INITIAL INSTALLATION - VENT TERMINATION RESTRICTIONS.
(3)When installing a vent pipe in a chase the minimum clearance to combustibles is 2” (51 mm).
NOTE: Vent pipe must not be longer than 18” (457 mm) maximum when installing straight through exterior wall.
Maintain manufacturer’s clearances to combustibles with venting.
Vent may extend between 6” (152 mm) and 18” (457 mm) maximum straight out.
When installing this unit in a corner the maximum distance after 45˚ elbow is 9” (228 mm).
If between 9” (229 mm) and 24” (610 mm), a 14” (356 mm) snorkel must be used.
