Installation Codes
The fireplace installation must conform to local codes. Before installing the
fireplace, consult the local building code agency to ensure that you are in
compliance with all applicable codes, including permits and inspections.
In the absence of local codes, the fireplace installation must conform to the
National Fuel Gas Code ANSI Z223.1 (in the United States) or the CAN/CGA-
B149 Installation Codes (in Canada). The appliance must be electrically
grounded in accordance with local codes or, in the absence of local codes with
the National Electric Code ANSI/NFPA No. 70 (in the United States), or to the
CSA C22.1Canadian Electric Code (in Canada).

High Altitude Installations
A.G.A./CGA Design Certified and U.L. Listed gas fireplaces are tested and
approved for elevations from 0 to 2,000 feet in the U.S.A. and from 0 to 4,500
feet in Canada.
When installing this fireplace at an elevation above 2,000 feet (in the United
States), it may be necessary to decrease the input rating by changing the
existing burner orifice to a smaller size. Input should be reduced four percent
(4%) for each 1,000 feet above sea level, unless the heating value of the gas has
been reduced, in which case this general rule will not apply. To identify the proper
orifice size, check with the local gas utility.
When installing this fireplace at an elevation between 2,000 and 4,500 feet (in
Canada), the input rating must be reduced by ten percent (10%).
When installing this fireplace at an elevation above 4,500 feet (in Canada), check
with local authorities.
Consult your local gas utility for assistance in determining the proper orifice for
your location.

spaced interior beads into the fireplace collar or
previously installed component end with four (4)
equally spaced indented sections.
 When the internal beads of each 8-5/8 inch
(219 mm) outer pipe line up, rotate the pipe section
clockwise about one-quarter (1/4) turn. The vent
pipe is now locked together.
 The first 90° elbow installed in the vent system of a
rear venting fireplace MUST BE in a vertical posi-
tion.
1. Apply the stove ce-
ment.
2. Line up the internal
beads and rotate the
pipe sections clock-
wise until locked.
3. Lock the vent compo-
nents into place.

C. Vent Termination
For Horizontal Terminations - To attach and secure
the termination to the last section of horizontal vent:
 Rotate and interlock the ends as described at the
beginning of the Installing Vent Components sec-
tion.
 The termination kit should pass through the wall
firestops from the exterior of the building.
 Adjust the termination cap to its final exterior posi-
tion on the building.
WARNING
THE TERMINATION CAP MUST BE
POSITIONED SO THAT THE ARROW IS
POINTING UP.
For roundcap termination kits:
 Use the exterior pipelock hole provided on the round
flange of the wall firestop to secure the vent pipe in
place.
For trapezoidal cap termination kits:
 Using screws, secure the cap to the exterior wall
through the flanges built into the cap.
 Use a high-temperature sealant or fiberglass rope
gasket to seal between the 8-5/8 inch
(219 mm) pipe and exterior firestop.
