THROUGH THE WALL VENTING: (HORIZONTAL VENTING)
Cut a 3 1/2 in. (8.9 cm) diameter hole in the wall at the point where the vent
connector is going to pass through the wall. Use the proper cement to secure
the 90° vent terminal provided with the water heater to the vent connector. The
distance between the edges of the 90° vent terminal and the exterior wall (see
Figure 3) must be 1 in.
(2.5 cm) . Use the proper cement and assembly
procedures to secure the vent connector joints between the terminal and the
blower outlet. Provide support brackets for every 5 feet
(1.5 m) of horizontal
vent.
IMPORTANT
All of the Venting connections must be leak checked with a soap and
water solution upon initial start up of the water heater. Any leaks must
be repaired before continuing operation of the water heater.
