sections
for correct positioning requirements) and verify if
you are able to install the vent kit in accordance with
the specifications illustrated in
Figure 3
.
Note:
a) The vent kit of this water heater can be installed
in any 360˚ configuration as long as the proper
clearances for installation, plumbing, operation,
and servicing are maintained (
see Figure 3a
).
b) The minimum inner radius for the vent pipe
curvature is 11" (27,9 cm) (use the water heater
outside radius as reference,
see Figure 3b
).
c) The maximum vent pipe curvature is 90˚
(
see Figure 3c
).
d) You can’t use both setup #3 and setup #4 on the
same vent pipe installation.
2) Locate where the vent termination is going to be
installed and cut a five and one half (5 1/2) inch
(14 cm) diameter clearance hole through the wall
(
see Figure 4
).
3) Outside of the building, position the outer wall
