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
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.
AIR FOR COMBUSTION AND VENTILATION
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 11.
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.
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.
www.usaprocom.com
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.
200068-01A6
AIR FOR COMBUSTION AND VENTILATION
Ventilation
WARNING: If the area in which
the heater may be operated does
not meet the required volume for
indoor combustion air, combustion and ventilation air shall be
provided 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.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the
wall connecting the two spaces (see options
1 and 2, Figure 2). You can also remove door
into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
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. If
an attic opening is unacceptable. Recongure
the conned space, by adding ventilation to
adjoining unconned space or removing doors
as indicated in Figure 2, Option 1 and 2. The
combined spaces must have enough fresh air
to supply all appliances in both spaces. Otherwise a lower input model must be installed
that meets the room size requirements.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED
OPERATION
When used as a vented heater, appliance
must be installed only in a solid-fuel burning
replace with a working ue constructed of
noncombustible material. You may use this
heater as a vented product. There are three
reasons for operating your heater as a vented
model:
1. The replace does not meet the clearance
requirements for vent-free operation.
2. State or local codes do not permit ventfree operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply, you
must permanently open chimney ue damper.
You must install the damper clamp accessory
(not provided). This will insure vented operation (see Figure 10). The damper clamp will
keep damper open. Installation instructions
are included with clamp accessory.
See chart below for the minimum permanent
ue opening you must provide. Attach damper
clamp so the minimum permanent opening will
be maintained at all times.
B. If combustible materials are less than 14"
to the replace, you must install appliance
at least 5" above the combustible ooring
(see Figure 9).
