CONDITION 2:

Where floor joists impede venting, a rise or drop to complete the vent termination is possible. All installations require 25mm (1 in.) clearance to combustibles.

Note:

A. The maximum horizontal vent length of 2.03m (80 in.) minus wall thickness should be considered when installing an offset vent arrangement.

B. Do not combine condition 1 (Figure 26) with condition 2 (Figure 27) in the same installation.

C. The maximum allowable drop from vent center-line to vent termination center-line (Figure 27) is 184mm (7.25 in.).
