Stardance® Direct Vent/Natural Vent Gas Heater
Supporting DIRECT-TEMP: Vertical Support
Vertical installations can be supported by two methods:
Ceiling Support (CS) (used in flat ceiling installation)
comes with a support plate and a support collar. Install
it by screwing the support plate to the top of the prop-
erly framed ceiling joist opening, using screws provided.
A round trim plate (TP) is attached to the ceiling, using
screws, to provide a finished appearance once installed.

The Cathedral Ceiling Support (CCS) may be used in
pitched or flat ceiling installations and comes with a sup-
port collar and a decorative two part square trim plate. In-
stall by inserting the support box down through the framed
joist opening (end with round hole first) in the ceiling using
tin snips, cut the corners of the open end of the box such
that the sides can be folded down over the top of the joist
framing members. Nail the folded sides to the top of the
framing. (Fig. 36)

A two-part square trim plate is provided to give a finished
look once installed. Simply fit the two halves of the trim
plate around the cathedral ceiling support box hanging
below the ceiling (overlapping if necessary) and screw
them to the ceiling. Both the ceiling support and cathedral
ceiling support can support a maximum of 40' (12 m) of
pipe.

Offsets:
If any offsets are necessary in the vertical system, an Off-
set Support (OS) should be installed directly above the
upper elbow of the offset. Install by attaching the offset
support band to the pipe with two #8 x 1/4" sheet metal
screws (minimum ) and secure the offset support straps
to surrounding structure. (Fig. 37)

Supporting DIRECT-TEMP: Horizontal Support
Horizontal runs of Direct-Temp should be supported ev-
ery 4' (122 cm) of pipe. This can be done with the use of
plumbers strapping or the offset support.
Adjustable Length (AJ)
An Adjustable Length is available to accommodate instal-
lations where non-standard lengths are necessary. The
adjustable length telescopes down over a standard length
of pipe and provides an extension range of 3Z\x" (89 mm)
to 10Z\x" (267 mm). Install by sliding the inlet end of the ad-
justable length over the outlet end of a standard length of
pipe. After positioning the adjustable length appropriately,
secure it to the standard length with two (2) #8 x1/4" sheet
metal screws (provided). Seal the area between both the
top and bottom of the adjustable length outer wall and
the outer wall of the standard length with an approved
silicone sealant.
Fire Stopping
DIRECT-TEMP must be firestopped wherever it passes
through floors, ceiling or walls. The only location where
a firestop is not required is at the roof level. Both vertical
support components with trim plates provide for firestop-
ping. The wall thimble also acts as a firestop. at other
locations, a firestop spacer (FS) should be installed. In
the attic the firestop should be placed on top of the joist
framing to prevent debris from falling into the joist fram-
ing. (Fig. 38)
