Reducing Vertical Vent from 5/8" to 4/7".
Reduced Vertical Installation
It is possible to reduce vertical vent runs from 5"/8" venting to 4"/7"
venting. Reduced vertical venting may only be used when the installation
exceeds 12 feet and terminates through the roof
,
and if the vertical vent
reducer is used with the following venting configuration.

Rear Vent Venting Runs
The
H42DF-O Rear Vent
has three possible installations which do not
require vertical lift, all of these installations require that you install the
RHS101 heat shield.
Heat Shield
The heat shield (RHS101) must be used on
all installations straight
through the wall
, at the point where the vent pipe connects to the
termination. With the heat shield, proper vent clearances can be
maintained.
The heat shield is not included with the fireplace.
To install the heat shield, slide one section over the vent pipe on the inside
of the wall opening, with the circular portion
inside the wall cavity
. Screw
the shield in place over the wall opening. Install the second section on
the outside of the wall opening sliding the circular portion into the wall
opening. Refer to Figure 19.

1. Straight Installation.
The height from the hearth to the center of the termination is 21
3/4". For straight installations use a 18" extension pipe (PXT-18)
with female/female connections. For shorter installations, cut the
PXT-12 to the desired length. Refer to figure 19a.
Ensure that the RHS101 heat shield is installed before attaching
the pipe to the termination.
Note:
For Rear Vent models, maximum horizontal run with no
vertical lift must never exceed 12".
