PENETRATING THE ROOF
To maintain a 2-inch clearance to the pipe on a roof with a pitch, a
rectangular opening must be cut.
STEP 1: Determine the center point through which the pipe will
penetrate the roof.
STEP 2: Determine the pitch of the roof. Pitch is the distance the
roof drops over a given span, usually 12 inches. A 6/12 pitch means
that the roof drops 6 inches for each 12 inches measured horizontally
down the roof.
STEP 3: From the center point determined in STEP 1, measure an
opening 17
1
/
inches wide (8
4
point). For a roof pitch between 0/12 (flat) and 6/12, measure an
opening 21 inches long (10 1/2 above and below the center point).
6/12 to 12/12 pitches: Measure 26 inches (13 above and below).
STEP 4: Remove the shingles around the opening measured and cut
out this section.
STEP 5: Add the next sections of pipe until the end penetrates the
roofline. Check to see that proper clearances are maintained. Extend
chimney by adding sections of double wall pipe until pipe is a
minimum of 30 inches above highest point of roof cutout. Termina-
tion and chimney must extend a minimum of 36 inches above highest
point where it passes through roof. See 10' rule (Figure 12).
10 FOOT RULE
All chimney terminations must extend a minimum of 3 feet in height
above the highest point where it passes through the roof and must be
at least 2 feet above the peak of the roof if within a horizontal distance
of 10 feet from the peak (see Figure 12).
TERMINATIONS
The fireplace and chimney system must be vented to the out-of-doors
and must be terminated with the listed round top or chase termina-
tions. If a chase termination is desired, refer to the instructions
supplied with the termination.
CAUTION: DO NOT SEAL VENTILATION OPENINGS
ON THE ROOFTOP FLASHING. FOLLOW THE IN-
STALLATION INSTRUCTIONS PROVIDED WITH THE
TERMINATION BEING USED.
FOR ROUND TOP TERMINATION
STEP 1: Slide the flashing over the pipe (no firestop is needed at the
roof level). Tack the flashing down at the top two corners with roofing
nails. Lay tile over the top and sides of the flashing and secure them to
the roof through the flashing with roof nails. Lay tiles under the lower
edge and secure these to the roof. Mastic all nail heads.
STEP 2: Install storm collar on double wall chimney, apply water-
proof caulking around flashing top and push storm collar down
securely on sealer and flashing (see Figure 13).
STEP 3: Place the termination onto the pipe end as illustrated and
secure with screws provided.
IMPORTANT: If an exposed portion of chimney is greater than 5
feet above the roof line, use support wires to keep chimney secure.
The support wires may be attached to the outer pipe of the chimney
with screws, provided the screws are not long enough to penetrate the
inner flue pipe.
A gas line may be installed for the purpose of installing a gas
appliance available through your local distributor. Use only 1/2"
black iron pipe and appropriate fittings. When installing a gas line,
a shut-off valve designed for installation outside the firebox is
recommended.

To install a gas line, remove the gas line plug located in the side
firebrick approx. 2" above the bottom. The plug must be tapped out
from the finished side towards the unfinished side (see Figure 14,
page 6). Insert the gas line parallel to the face. Fill any gap between
the gas line and the hole in the firebrick with the refractory cement
or commercial furnace cement (see Figure 15, page 6).
WARNING: All the gas piping and connections must be
tested for leaks after the installation is completed. Be
sure gas valve is turned on. Apply soapsuds solution
to all connections and joints. If bubbles appear, leaks
must be detected and corrected. DO NOT use a match
or open flame of any kind to test leaks. Never operate
any appliance with leaky connections.
The gas pipe is intended for connection to an unvented gas log set or
to a decorative gas appliance.
If you will install an unvented gas log set, ONLY UNVENTED GAS
LOG SETS WHICH HAVE BEEN FOUND TO COMPLY WITH
THE STANDARD FOR UNVENTED ROOM HEATERS, ANS/IAS/
AGA Z21.11.2, ARE TO BE INSTALLED IN THIS FIREPLACE.
NOTE: An appropriate Vanguard hood must be installed when
using an unvented gas log set.
WARNING: DO NOT OPERATE AN UNVENTED GAS LOG
SET IN THIS FIREPLACE WITH THE CHIMNEY REMOVED.
If you will install a decorative gas appliance, the decorative gas
appliance must comply with the Standard for Decorative Gas
Appliances for Installation in solid Fuel burning Fireplaces,
ANS Z21.60-1996 and shall also be installed in accordance with the
National Fuel Gas code, ANS Z223.1-1996.
WARNING: WHEN USING A DECORATIVE APPLIANCE,
THE DAMPER MUST BE REMOVED OR PERMANENTLY
LOCKED IN THE FULLY OPEN POSITION.
