shock can cause personal injury or death.

DO NOT operate this water heater with the rain cap removed or recirculation of combustion products may occur. Water may also collect inside larger combustion-air pipe and flow to the burner assembly. Failure to follow this warning could result in product damage, or improper operation, personal injury or death.

CAUTION

DO NOT use field-supplied couplings to extend pipes. Airflow restriction will occur and the water heater pressure switches may cause intermittent problems.

Vertical Installation (Recommended)

1.Become familiar with coaxial vent kit part no. 239-44069-01.

2.Determine the best location for the termination kit.

3.Cut the recommended 5” diameter hole.

4.Partially assemble vent kit by performing the following:

a.Cement concentric Y fitting to larger diameter pipe. (See Figure 20).

b.Cement rain cap to smaller diameter pipe. (See Figure 21).
