Final installation of the vent system
Figure 35
From the outside of the building, slide the wall discharge terminal through the vent wall passage. A
supplied rubber wall plate can be installed on the exterior of the building. Slide the inner wall plate onto
the terminal. If necessary apply silicon sealant to fill up spaces between vent terminal and the wall. Vent
connections must be firmly pressed together so that the gaskets form an airtight seal.
NOTE
When the total vent system length is greater than 5ft. (1,52 m), condensate will form which could damage
the water heater. For vent lengths greater than 5ft. (1,52 m), a condensate collector and trap must be
installed.
