We strongly recommend that you DO NOT
install B-Vent Gas Appliances in strong negative air locations, such as a basement or a public facility. Living rooms with cathedral ceilings
could be susceptible to a negative air situation,
but such installations can be overcome through
raising the termination, depending on specific
installations. This fireplace uses room air for
normal operation and could have problems
establishing a positive draft in negative air locations. in lieu, we recommend a direct vent
appliance.

D. SETTING THE UNIT
1. Positioning the Firebox.
This appliance may be placed on a smooth
combustible or non-combustible, continuous
flat surface. When the appliance is installed
directly on carpeting, tile or other combustible
material other than wood flooring, the appliance
shall be installed on a metal or wood panel
extending the full width and depth of the appli-

WARNING - RISK OF FIRE!
AIR SPACE CLEARANCES MUST BE MAINTAINED AT ALL TIMES.
ance. Slide the unit into position and level the appliance from side-to-side and front-to-back. Shim with
non-combustible material as necessary.
Secure the appliance by bending out the Nailing
Flanges on each side of the appliance and nail to
Framing. The Nailing Flanges have been positioned
5/8" back from the front of the unit to allow the addition of drywall.
1. Vent Height.
This appliance requires a 4” B-vent for operation. Never
downsize pipe! It must be terminated above the roof line.
Follow all B-vent requirements and installation instructions,
including minimum clearances.
The minimum height of vent installation must be nine feet
from the top or 12 feet from the base of the appliance.
Horizontal run must never exceed 50% of the height of the
vent system as shown in Figure 4.
2. Attaching Venting.
a. Assembling Vent Sections. Attach a straight Vent
Section to the top of the appliance. Use only B-vent
sections.
b. Using Elbows. Elbows exceeding 45° from the vertical shall be considered horizontal and therefore adapt
horizontal run limitations. See Figure 5.
c. Penetrating the Ceiling. Mark and cut out an opening in the ceiling for a Firestop Spacer. Frame the opening with the same size of lumber used in the Ceiling
Joists.
d. Installing the Firestop Spacers. Firestop Spacers
must be used whenever the Venting penetrates a ceiling/floor area. In all situations, Firestop Spacers are to
be nailed to the Ceiling Joists from the bottom or appliance side, EXCEPT when the space above is an insulated ceiling or attic space. In this situation, the Firestop
Spacer must be secured from the top side to meet fire
stopping requirements.
Install the Firestop Spacer by positioning and securing
the four sides of the Firestop Spacer to the Joists using
a minimum of [3] Fasteners per side..
Figure 4 - Venting Off the Top of Appliance
NOTE: Vertical rise off the top of the unit before elbowing creates a less restrictive venting environment.
WARNING - RISK OF FIRE!
THE HORIZONTAL RUN OF VENT MUST HAVE A
1/4” RISE FOR EVERY 1 FT. OF RUN TOWARDS
THE TERMINATION. NEVER ALLOW THE VENT
TO RUN DOWNWARD. THIS COULD CAUSE
HIGH TEMPERATURES AND MAY PRESENT A
FIRE HAZARD.

PROVISIONS SHALL BE MADE TO PROVIDE ADEQUATE COMBUSTION AND VENTILATION AIR.
e. Securing Vent System. Continue assembling the Vent
Sections up through the Firestop Spacers as needed. Vent
Sections must be locked into position. Elbows and Chimney
Stabilizers have straps for securing these parts to Joists or
Rafters.
f. Marking the Exit Point in the Roof. Locate the point
where the Venting will exit the roof by plumbing down to the
center of the Vent System. Drive a nail up through the roof
to mark the center. See Figure 6a.
g. Cutting Out the Hole in the Roof. Measure to either
side of the nail and mark the opening required to meet minimum clearances per Venting requirements. This is mea-
sured on the horizontal; actual length may be larger depend-
ing on the pitch of the roof. Cut out and frame the opening.
See chapter 25 of the Uniform Building Code for Roof
Framing details.
A one inch or greater minimum air space clearance (see
Vent Instructions) must be maintained between the vent
section and the roof.
h. Install Roof Flashing or Site-produced Chase Top.
Position a Roof Flashing or a site-produced Chase Top and
secure into place.
i. Assembling Vent Sections. Continue to add vent s e c-
tions through the roof opening, maintaining minimum air
space clearance.
j. Termination Cap. Major building codes specify a mini-
mum termination height above the roof top depending on the
roof pitch. It is strongly recommended that the cap should
be at least 2’ higher than anything within 10’ of it, and a min-
imum of 3’ out of the roof. This will help to ensure the best
air flow.
Unlisted Cap. If you are using an unlisted Termination
cap and your Vent Section is at least 8 feet from a vertical
wall, follow the information in Figure 6b and Table 1 to determine the allowable termination height and location.
G270 SERIES B - VENT GAS APPLIANCE
CAUTION
Figure 6a - Roof Exiting
Figure 6b - Vent Height for Vertical Termination
Measure the roof pitch. (Roof pitch is X/12 as shown in
Figure 6b.) Find your roof pitch in Figure 8 to determine the
minimum height the Termination Cap must be located from
the point where the Vent Section penetrates the roof (H in
Figure 6b).
Listed Cap. If you are using a listed Termination Cap, you
must follow the manufacturer’s installation instructions for
minimum clearances to roof and any obstructions.
Note: Be sure to provide intermediate support
for the vent during construction and check to
be sure inadvertent loading has not dislodged
the vent from the appliance or any vent joint.

WARNING:
WARNING - RISK OF FIRE!
A Gas appliance must not be con-
nected to a chimney flue serving a
separate Solid - Fuel Burning appli-
ance.
3. Check Venting System.
Check the Venting System to assure proper operation. This can be done with a match while the unit is operati n g .
Hold a lighted match at the bottom edge of the Drafthood opening. If the flames and smoke remain upright, ventilation is acceptable. If the flames and smoke are drawn into the Drafthood, this means ventilation is good. If
the flames and smoke are forced away from the Drafthood, this may indicate a ventilation blockage or down draft
resulting in gas spillage into the home. If this occurs, turn off the fireplace and do not burn it until it has been
inspected by a qualified service person. See Figure 7.
ALWAYS MAINTAIN MINIMUM CLEARANCES OR GREATER AROUND THE
CHIMNEY SYSTEM. DO NOT PACK AIR
SPACES WITH INSULATION OR OTHER
MATERIAL.
4. Installing an Outside Air Kit (strongly recom-
m e n d e d ) .
An AK14 Outside Air Kit should be purchased as a feature with this fireplace. An Outside Air Kit helps to
decrease the amount of room air taken, by utilizing outside air for combustion. The Outside Air Kit can only be
installed on the left side of the fireplace. Remove the
Outside Air Knock-out located behind the Gas Access
Panel. Install the AK14 as detailed in the installation
instructions provided with the Kit.
Figure 7 - Testing Ventilation
A maximum of 40’ of Air Kit ducting is allowed. The Air
Kit must terminate at least four feet below the venting
termination and must terminate to the outside.
WARNING!
Exhaust products of gasoline engines are
hazardous. The outside air must not be
taken from a garage space, attic spaces,
basements, or above the roofing where
other heating appliances, fans, or chimneys exhaust or utilize air.
NOTE: The Outside Air Kit can terminate at any
level with the exception that it must terminate at
least one foot below the chimney Terminal Cap.
