FIGURE 23

Apply hi-temp red silicone (included) around the collar on air manifold box. Pull corrugated vent tube all the way on to collar and secure with one sheet metal screw (approx. 3/4 in. (19mm) up from edge of vent tube. Pull gear clamp past screw and tighten.

Check the level or slope of the venting again, and adjust if required.

CONDITION 2:

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

Note:

A. The maximum horizontal vent length of 80 in. (2.03m) 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 7.25 in. (184mm).

OFFSET VENT ARRANGEMENT

CONDITION 1:

Where a straight vent arrangement is impossible, a horizontal 90 degree maximum bend can be made. Use the water heater casing outer diameter as a template to form the corrugated tube.
