WaLL Support (WS)
1. The wall support consists of an Anchor Plate
and a prefabricated frame with mounting
brackets and angled struts for bracing.
2. Used to support the chimney in vertical runs, it
maintains the chimney at an adjustable distance
between 2-1/2” and 7-1/2” from the wall (see
Figure 25).
3. The maximum weight allowable on the wall
support depends if the support is attached to a
metal structure or a wood structure (see Table
6 for maximum chimney height).
4. The installation begins by attaching the frame
of the wall support to a rigid metal or wood
structure. Adjust the braces to have a minimum
of 45° angle from horizontal. Once the frame of
the wall support is fixed to a rigid structure, the
installation is the same as the Anchor Plate.
Height Limit - See Section A, Table 6 for
maximum height of Wall Support (WS)
WaLL guIDE (Wg)
1. The wall guide is used as a lateral guide to resist
lateral or side load only, it is not designed for
carrying the weight of a vertical chimney.
It also ensure a minimum clearance of 1” to
combustibles for model DIS and 4” for model DAS.
See Figure 26 (wall guide).
2. The proper location to install the wall guide is
immediately below a locking band. The locking
band must be able to move without interfering
with the guide when thermal expansion occurs.
See Figure 27 (wall guide location).
3. The wall guide can be installed with a wall band
Figure 26
extension for greater clearances up to 4-1/4” for
model DIS and up to 7-1/4” for DAS. See Figure 28
(wall guide extension).
4. Special considerations must be taken when
installing on exterior wall. A wall guide must be
installed between 6’ and 10’ below the highest wall
support to stabilize the free standing portion of
the chimney. Do not install a expansion length in
this area due to bending forces induced by
the freestanding portion. See Figure 29 (special
considerations).
FLoor guIDE (Fg)
1. The floor guide is used the same manner
as the wall guide but it is modified for use at
floor penetrations. See Figure 30 (floor guide).
SuSpEnSIon BanD (SB)
1. Suspension band is used to support and
guide the chimney in horizontal runs. It
consists of a band, a flexible strap (by others),
a trolley and a rail.
2. The trolley and rail allow up to 4” of travel
to compensate thermal expansion.
3. See Section A, Table 7 for maximum
distance between two supports or guide.
4. Important: The flexible strap must be
at least 3/4” wide and 0.036” thick made of
galvanized or stainless steel. YOU MUST USED
TWO LAYERS OF FLEXIBLE STRAP to attach the
band to the trolley.
