QUALIFIED INSTALLING AGENCY
Only a qualied agency should install and
replace gas piping, gas utilization equipment
or accessories, and repair and equipment servicing. The term “qualied agency” means any
individual, rm, corporation, or company that
either in person or through a representative
is engaged in and is responsible for:
a) Installing, testing, or replacing gas piping
or
b) Connecting, installing, testing, repairing,
or servicing equipment; that is experienced
in such work; that is familiar with all precautions required; and that has complied with
all the requirement of the authority having
jurisdiction.
In areas that prohibit the use of vent-free
heaters, the log set has been tested and
approved to the ANSI Z21.60 standard for
Vented Decorative Logs. When used as a
vented log set refer to additional instructions
on page 12.
WATER VAPOR: A BY-PRODUCT OF
UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30 mL) of water
for every 1,000 BTUs (0.3 KWs) of gas input
per hour. Unvented room heaters are recommended as supplemental heat (a room) rather
than a primary heat source (an entire house).
In most supplemental heat applications, the
water vapor does not create a problem. In
most applications, the water vapor enhances
the low humidity atmosphere experienced
during cold weather.
The following steps will help ensure that water
vapor does not become a problem.
1. Be sure the heater is sized properly for the
application, including ample combustion
air and circulation air.
2. If high humidity is experienced, a dehumidier may be used to help lower the
water vapor content of the air.
3. Do not use an unvented room heater as
the primary heat source.
UNPACKING
CAUTION: Do not remove the
metal data plates from the burner
pan. The data plates contain
important product information.
1. Remove logs and burner base assembly
from carton. NOTE: Do not pick up burner
base assembly by burners as this could
damage heater. Always handle base assembly by grate.
2. Remove all protective packaging applied
to logs and base for shipment.
3. Check all items for any shipping damage.
If damaged, promptly inform dealer where
you purchased the heater.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
not be installed in a conned
space or unusually tight construction unless provisions are provided for adequate combustion and
ventilation air. Read the following
instructions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Today’s homes are built more energy efcient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors
to keep the cold air out and the warm air in.
During heating months, home owners want
their homes as airtight as possible.
While it is good to make your home energy
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning appliances need fresh air for proper combustion
and ventilation.
Exhaust fans, replaces, clothes dryers and
fuel burning appliances draw air from the house
to operate. You must provide adequate fresh
air for these appliances. This will insure proper
venting of vented fuel-burning appliances.
WARNING: This heater
shall not be installed in a room
or space unless the required
volume of indoor combustion
air is provided by the method
described in the National Fuel
Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas
Code, or applicable local codes.
WARNING: If the area in which
the heater may be operated is
smaller than that dened as
an unconned space or if the
building is of unusually tight
construction, provide adequate
combustion and ventilation air
by one of the methods described
in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or
applicable local codes.

AIR FOR COMBUSTION AND VENTILATION
VENTILATION AIR
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two permanent openings: one within 12" of the ceiling
and one within 12" of the oor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
IMPORTANT: Do not provide openings
for inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.
Rework worksheet, adding the space of the
adjoining unconned space. The combined
spaces must have enough fresh air to supply
all appliances in both spaces.
