Prior to starting your venting installation, refer to the section on Allowable Vent Configurations to make sure your
plans fall into the allowable limits of horizontal and vertical installations.
When planning your installation, it will be necessary to select the proper length of vent pipe for your particular
requirements. For horizontal installations, refer to the section on Clearances to Combustibles to determine the
minimum clearance from the rear of the appliance to the wall. It is also important to note the wall thickness. Select
the amount of vertical rise desired for “vertical-to-horizontal” type installations. To determine the length of vent
pipe required for vertical installations, measure the distance from the appliance flue outlet to the ceiling, the ceiling
thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the roof line. For
two-story applications, firestops are required at each floor level. If an offset is needed in the attic, additional pipe
and elbows will be required.

Figure 25: Securing the Unit.
1.Using eight (8) T-20 screws provided,
install the drywall supports right and left
as well as the heat shield in the middle, as
shown in Figure 28.
2.Using eight (8) T20 screws provided,
attach back stand-offs, as shown in Figure
24.
Once the unit is in its final position,
confirm that you have access to
power, gas supply, that your non-
combustible zone requirements
are met, that you meet all the
minimum vent requirements, and
that your planned vent terminal
location will meet all of the vent
termination clearances. Secure
the unit to the floor, with at
least four (4) wood screws, two
(2) on either side of the unit’s
bottom nailing flange. Secure the
side stand-offs to the framing
members using four (4) wood
screws, one (1) for each stand-off
and to the header, one (1) wood
screw for each drywall support.
