• turn off gas supply to the fireplace or firebox.
• Position appliance in fireplace or firebox.
• connect gas line.
• secure appliance.
• operate the appliance and check operation.
• maintain adequate clearances for accessibility for purposes of servicing
and proper operation.
• minimum clearances include any projections such as shelves, window
sills, mantels, spacers/standoffs or surfaces to combustible construc-
tion etc. above the appliance. Paint or lacquer used to finish the mantel
must be heat resistant in order to avoid discoloration.
(actual amount of Btu/Hr used)
the space in the above example is a confined space because the actual
Btu/Hr used is more than the maximum Btu/Hr the space can support.
You must provide additional fresh air.
Your options are:
a. rework equations adding the space of adjoining room(s). if the extra
volume provides an unconfined space, then remove door or add ven-
tilation grills between rooms. refer to National Fuel gas code, aNsi
Zꢀꢀꢁ.1 - latest edition, section 5.ꢁ.
b. Vent room directly to the outdoors. refer to National Fuel gas code,
aNsi Zꢀꢀꢁ.1 - latest edition, section 5.ꢁ.
c. install a lower Btu/Hr appliance, such as a ꢀ4,000 Btu/Hr, to make
the area an unconfined space.
Check Gas Type
This appliance can only be connected to the gas type specified on the
appliance rating plate. This appliance can not be modified in the field
for a different gas type. If the gas supply differs, DO NOT INSTALL the
appliance. Contact your dealer to obtain the correct appliance.
if the actual Btu/Hr used is less than the maximum Btu/Hr the space
can support, then the space is an unconfined space. You will need no
additional fresh air ventilation for an unconfined space.
CLEARANCES
WARNING
If the area in which the heater may be operated is smaller
than that defined as an unconfined space or if the build-
ing is of unusually tight construction, you must provide
adequate combustion and ventilation air by one of the
methods described in the National Fuel Gas Code, ANSI
Z223.1, Section 5.3 or applicable local codes.

gas leaks.
the appliance gas inlet connection is ꢁ/8" NPt at the regulator/valve,
located on the left side facing the appliance. if a right side connection is
required, the connection pipe may be piped under the rear of the appliance
to end at the left hand side for connection to the inlet.
When tightening up the joint to the regulator hold the regulator securely
with a wrench to prevent the regulator from moving.
Step 4. PLACING THE LOGS
Checking Gas Connections: test all gas joints from the gas meter to the
gas appliance regulator for leaks after completing connection.
WARNINGS
Do not add extra logs or ornaments such as pine cones,
vermiculite or rock wool. Using these added items can
cause sooting.
WARNING
Never use an open flame to check for leaks.
Do not place any lava rock on logs or burners. This
may cause sooting. Only place lava rock on floor of
fireplace.
turn on gas supply and test for gas leaks using a gas leak test solution (also
referred to as bubble leak solution). Note: using a soapy water solution
(50% dish soap, 50% water) is an effective leak test solution but it is not
