10. VENT TERMINAL AND COMBUSTION

AIR INLET HOOD

The vent terminal is shipped in the burner
compartment. See Figure 7. Remove the two shipping
screws and separate the two-piece assembly. Install the
vent terminal by using the four screws provided.

Make

sure gasket is in place

. See Figure 8. The combustion

air intake hood is factory installed.

11. OPTIONAL VERTICAL VENTING

With the optional vertical venting kit (VVK-5) this unit
may be vented vertically through a roof or overhang.
The kit includes a stainless steel transition drain tee,
silicone sealant, and drain tubing.

If unit is installed with vertical vent kit, annually
inspect the vent system and drain. Replace any portion
of the vent system that shows signs of deterioration.
Make sure drain is open and free of obstruction.

FIGURE 8

VENT TERMINAL AND COMBUSTION AIR INTAKE

CAUTION

Vent terminal must be installed as shown in Figure 8 for proper operation of the heating system.

NOTE: The inner vent hood gasket is designed to stretch over and seal around the combustion
air blower outlet. This is a very critical seal to prevent water and flue products from entering the
unit. Care must be taken to insure this gasket is in place and sealing properly.
