Figure 3G

Pull and connect the 80mm (3-1/8 in.) corrugated pipe to the water heater’s flue tube reducer with hi-temp red silicone and gear clamp. Make sure this connection is tight and leak proof.

*The sealant between 80mm (3-1/8 in.) corrugated pipe and water heater’s flue tube reducer must be hi-temp red sili- cone or other material suitable for 315°C (600°F) continu- ous service.

Figure 3H

Apply silicone around 152mm (6 in.) collar on air manifold box. Pull corrugated vent tube all the way on to collar and secure with one sheet metal screw (approx. 19mm (3/4 in.) up from edge of vent tube. Pull gear clamp past screw and tighten.

SLOPE

Figure 3L - CONDITION 2

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

Note:

A.The maximum horizontal vent pipe length of 2.28m (90 in.) minus wall thickness should be considered when installing an offset vent arrangement.

B.Do not combine condition 1 (3K) with condition 2 (3L) in the same installation.
