We strongly recommend that you DO NOT
install B-Vent Gas Appliances in strong nega-
tive air locations, such as a basement or a pub-
lic 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 loca-
tions. in lieu, we recommend a direct vent
appliance.

vent system as shown in Figure 4.
Figure 4 - Venting Off the Top of Appliance
Figure 5 - Using Elbows
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 verti-
cal shall be considered horizontal and therefore adapt
horizontal run limitations. See Figure 5.
c. Penetrating the Ceiling. Mark and cut out an open-
ing in the ceiling for a Firestop Spacer. Frame the open-
ing 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 ceil-
ing/floor area. In all situations, Firestop Spacers are to
be nailed to the Ceiling Joists from the bottom or appli-
ance side, EXCEPT when the space above is an insulat-
ed 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..
NOTE: Vertical rise off the top of the unit before elbow-
ing creates a less restrictive venting environment.
WARNING - RISK OF FIRE!
AIR SPACE CLEARANCES MUST BE MAINTAINED AT ALL TIMES.
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.

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 mini-
mum 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 sec-
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.
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.
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 deter-
mine the allowable termination height and location.
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.
Figure 6b - Vent Height for Vertical Termination

G270 SERIES B - VENT GAS APPLIANCE
3. Check Venting System.
Check the Venting System to assure proper operation. This can be done with a match while the unit is operat-
ing.
Hold a lighted match at the bottom edge of the Drafthood opening. If the flames and smoke remain upright, ven-
tilation 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.
4. Installing an Outside Air Kit (strongly recom-
mended).
An AK14 Outside Air Kit should be purchased as a fea-
ture with this fireplace. An Outside Air Kit helps to
decrease the amount of room air taken, by utilizing out-
side 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.
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.
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.
Figure 7 - Testing Ventilation
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 chim-
neys exhaust or utilize air.
WARNING - RISK OF FIRE!
ALWAYS MAINTAIN MINIMUM CLEAR-
ANCES OR GREATER AROUND THE
CHIMNEY SYSTEM. DO NOT PACK AIR
SPACES WITH INSULATION OR OTHER
MATERIAL.
WARNING:
A Gas appliance must not be con-
nected to a chimney flue serving a
separate Solid - Fuel Burning appli-
ance.

1. High Altitude Installation.
For U.S. installation, units are tested and approved for eleva-
tions from 0-2000 feet. When installing this unit at an elevation
above 2000 feet, United States codes require a decrease of the
input rating by changing the existing burner orifice to a smaller
size.
Input should be reduced 4% for each 1000 feet above sea level.
Check with the local gas utility for proper orifice size identifica-
tion.
For Canada, units are certified for elevations from 0-4500 feet.
When installing this unit at an elevation between 0-4500 feet in
Canada, the input rating does not need to be reduced. When
installing this unit at an elevation above 4500 feet in Canada,
check with local authorities.

unless knob is pushed in slightly. Do not force.
4. Wait five (5) minutes to clear out any gas. If you then
smell gas, STOP! Follow “B” in the safety information on
this page. If you don’t smell gas, go on to the next step.
FOR YOUR SAFETY, READ BEFORE LIGHTING.
5. Initial and Seasonal Lighting procedure. Initial lighting con-
stitutes the first time the appliance has been lit after
installation. Seasonal lighting refers to lighting the appli-
ance after it has been unused and the Gas Valve has
been turned to “OFF”.
Be sure the knob has been turned to the “OFF” position.
Also, your unit may have a Rocker Switch installed inside
the Lower Panel; if it does, this also needs to be turned
to the “OFF” position. If not ,do so and allow the appli-
ance to sit for five [5] minutes so that any gas that may
have accumulated in the main Burner Compartment
escapes.
Turn the gas knob to “PILOT”, as shown in Figure 17,
and press in. While holding it in, light the pilot with a
match. Continue to hold in the gas knob for about one
minute after the pilot is lit. Release the gas knob. The
pilot should remain lit. If it goes out, turn everything to
the “OFF” position, let it sit for five minutes and repeat
this step again.
When the pilot remains lit, turn the gas knob to the “ON”
position. See Figure 17. Watch you appliance display
beautiful, dancing flames. Initially, the flames may
resemble more of a blue color but after the first 20 min-
utes of operation, they will become more yellow.

E. FUEL/FIELD FUEL CONVERSION INSTRUCTIONS
Do not burn wood or other material in this appliance.
Natural or Propane gas conversions necessary to meet the application are to be made by a qualified technician,
using Heatilator specified and approved parts only.
F. START-UP ISSUES
Issue: Causes and Possible Solutions:
1. Condensation on Glass:
(If applicable)
2. Blue flames:
3. Odor from unit:
4. Film on Glass:
(If applicable)
1. This is a result of gas combustion and temperature
variations. As the unit warms, this condensation should
disappear.
2. This is a result of normal operation and the flames will
begin to yellow as the unit is allowed to burn.
3. When first operated, this unit may release an odor for
the first several hours. This is caused by the curing of the
paint and the burning off of any oils remaining from manu-
facturing.
This is a normal result of the curing process of the paint
and Logs. If the Glass is not cleaned within 4 - 6 hours of
initial burning, this may require the use of a non-abrasive
cleaner to remove, such as Brasso.
WARNING!
NEVER USE GASOLINE , GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHAR-
COAL LIGHTER FLUID OR SIMILAR LIQUIDS IN THIS APPLIANCE. KEEP ANY FLAM-
MABLE LIQUIDS A SAFE DISTANCE FROM THE APPLIANCE.
In the event that your appliance must be converted to burn an alternate gas, please contact your local Dealer or
Heatilator Customer Relations at: Heatilator, 1915 W. Saunders Street, Mt. Pleasant, IA 52641.

1. Cleaning the Burner and Control Compartment.
Keep the burner and control compartment clean by
brushing and vacuuming at least once a year. Always
turn off the wall switch (or remote control) and gas
valve before cleaning. Failure to do so may shorten
the life of the components.
2. Checking Flame Patterns.
Visually check the flame of the burner periodically,
making sure the flames are steady, not lifting or float-
ing. The flame color should be blue with yellow tips.
See Figure 5. The ignitor (electronic) or thermopile
and thermocouple (standing Pilot) tips should be cov-
ered with flame. See Figures 2 through 4.
If the vent configuration is installed incorrectly, the
vent may cause the flames inside the appliance to lift
or “ghost”, which is a dangerous situation. Inspect
the flames after installation to ensure proper perfor-
mance. See Figure 5. If the vent configuration is cor-
rect, yet the flames are lifting or ghosting, shut off gas
to the appliance and contact the dealer.
