VENT CONNECTIONS

After the location for the vent terminal has been selected as outlined in Figures 3, 4 & 12, use the following illustrations for installation:

FIGURE 14

LOCATING CLEARANCE HOLE FOR VENT

Cut a clearance hole, approximately 178mm (7 in.) in diameter, through the exterior wall for the vent assembly. The recommended distance, measured from the hole center to bottom of water heater, is 1.72m (68 in.) for 40 gal. models and 1.93m (76 in.) for 50 gal., 50 gal. Hi-Input and 75 gal. models. The maximum distance recommended is 2.03m (80 in.) or in compliance with Figure 16.

Where the wall is combustible and the wall thickness is over 356mm (14 in.), 25mm (1 in.) clearance to combustible materials around the vent terminal is needed. The first 356mm (14 in.) is zero clearance.

HIGH RISE VENT ARRANGEMENT

When the height H (From vent terminal center line to bottom of heater) is over 80 in. (2.03m), it is a high rise vent arrangement. In this case the minimum distance “D” from the center of the water heater to the outside wall surface is 560mm (22 in.), and the maximum height of “H” is 3.66m (12 ft.).
