NOTE:

SHORT LEGS REDUCE THE HEIGHT BY 2 1/4”.

•The maximum horizontal run made directly off the rear of the stove shall be no more than 12" and must then be connected to a 14" snorkel cap (Simpson Dura-vent #982).

•The horizontal termination cap must maintain a 3" clearance to any overhead combustible projections exceeding 2 1/2" or less. Maintain 12" clearance from projections exceeding 2 1/2". See Figure 8, page for complete termination clearance information.

•Any horizontal run of vent must be level or have a 1/4" rise for every foot of run toward the termination cap.

NEVER ALLOW THE VENTING TO SLOPE DOWNWARD, AS HIGH TEMPERATURES MAY RESULT AND CREATE A HAZARDOUS CONDITION.

•	Vent Pipe Clearance to Combustible Materials: For all
	horizontal runs, a 2" top clearance and a 1" side and
	bottom clearance must be maintained.
•	Wall Pass-through:A minimum 10" X 10" square cutout
	is required to maintain proper clearances through
