! WARNING:
1. The roof jack and vent pipe as deter-
mined from the chart on in Figure 7
must be applied.
2. The indicating line near the bottom of
the roof jack must extend below the
finished ceiling.
3. The vent pipe must be attached to the
furnace flue collar with the sheet metal
screw provided.
4. DO NOT install any elbows (adjust-
able or non-adjustable) or a stack
damper in the venting system.
NOTICE: Accuracy in locating the base pan
and the roof jack openings with respect to the
flue outlet is required to avoid hazardous mis-
alignment of the air and vent systems. (See
Figure 1)
Use only the SRJ series roof jack as specified
on the furnace label.
Cut an approximate 8-1/4" diameter opening
through the roof and ceiling directly in line with
the flue connection on the top of the furnace.
A roof jack adaptor is required for use on a
sloping roof. Center the adaptor opening over
the roof opening, use sealant or caulking under
the adaptor. Use roofing nails or screws on
wood construction or sheet metal screws on
metal roofs (caulking, nails or screws not pro-
vided).
Insert the vent pipe into the bottom of the roof
jack; locking slot, downward, toward the fur-
nace. Slide the pipe into the roof jack to a length
that will allow a convenient reach to the connec-
tion at the top of the furnace.
Ease the roof jack assembly through the open-
ings. The lower portion of the outer barrel must
extend through the finished ceiling as indicated
on the barrel. Use sealant or caulking on the
roof or adaptor to seal under the flashing of the
roof jack assembly.
Extend the vent pipe down to engage the locking
slot with the screw in the top of the furnace flue
pipe. Turn to lock and tighten the screw. All
joints and connections should be inspected
before start up of the furnace. (See Figures 8
& 9)
Fasten the ceiling trim/fire stop plates around
the upper barrel with four nails or wood screws
(not provided).
NOTE: Model SRJ-3, 4, and 5 roof jacks
permit the top section to be removed for transit
of the dwelling. If the top is removed, remaining
openings must be sealed from rain, debris, etc.,
until the top is replaced. A plastic accessory
cap is to be fastened to the lower roof jack
section with the same screws used to mount the
roof jack cap assembly. (See Figure 8)
