 U39 ULTIMATE Direct Vent Freestanding Gas Stove
INSTALLATION
Diagram 11: The upper half of the fl ashing is 
installed under the roofi ng material and not 
nailed down until the chimney is installed. This 
allows for small adjustments.
4)  Assemble the desired lengths of black pipe 
and  elbows necessary to reach from the 
appliance adaptor up though the Round 
Support Box. Insure that all pipes and elbow 
connections are in the fully twist-locked 
position and sealed.
5)  Cut a hole in the roof centred on the small 
drilled hole placed in the roof in Step 2. The 
hole should be of suffi cient size to meet 
the minimum requirements for clearance 
to combustibles of 1-1/4". Slip the fl ashing 
under the shingles (shingles should overlap 
half the fl ashing) as per diagram 11.
Diagram 12
7)  Ensure vent is vertical and secure the base 
of the fl ashing to the roof with roofi ng rails, 
slide storm collar over the pipe section and 
seal with a mastic.
8)  Install the vertical termination cap by twist 
locking it.
 Notes:
 a)  For multistorey vertical installations, 
a Ceiling Fire stop (Part # 963) is 
required at the second fl oor, and any 
subsequent fl oor. Diagram 13.  The 
opening should be framed to 10 " x 10" 
inside dimensions, in the same manner 
as shown in diagram 10. 
6)  Continue to assemble pipe lengths.
Note:  If an offset is necessary in the attic to 
avoid obstructions, it is important to 
support the vent pipe every 3 feet, to 
avoid excessive stress on the elbows, 
and possible separation.  Wall straps 
are available for this purpose.  See 
diagram 7. 
 
 
Galvanized pipe and elbows may be utilized 
in the attic as well as above the roofl ine.  
The galvanized fi nish is desirable above 
the roofl ine due to its higher corrosion 
resistance.
 
Continue to add pipe sections through the 
fl ashing until the height of the vent cap meets 
the minimum height requirements specifi ed 
in diagram 12 or local codes.  Note that for 
steep roof pitches, the vertical height must 
be increased.  A poor draft, or down drafting 
can result from high wind conditions near 
big trees or adjoining roof lines, in these 
cases, increasing the vent height may solve 
the problem.

b)  Any occupied areas above the fi rst fl oor, 
including closets and storage spaces, 
through which the vertical vent passes, must 
be enclosed. 
CATHEDRAL CEILINGS
Round Support (RDS) &
Square Support (SQS)
If your home has a cathedral ceiling (no attic 
space between the ceiling and the roof), install 
the chimney and support as follows.
1)  Situate the chimney in a convenient location 
as near as possible to the appliance outlet.  
Cut and frame a hole in the roof for the 
support. The sides of this hole must be 
vertical with 1 1/4" clearance.
2)  Place the support in the opening. Lower it 
to the correct height as determined by the 
table and diagram below.
