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 floor. 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, NFPA 54/ ANSI Z223.1, Section 5.3, 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 unconfined space. The combined spaces must have enough fresh air to
supply all appliances in both spaces.
INSTALLATION
NOTICE:
This heater is intended for use as supplemental heat. Use this heater along with your primary
heating system. Do not install this heater as your primary heat source. If you have a central heating system,
you may run system's circulating blower while using the heater. This will help circulate the heat throughout
the house.
WARNING:
A qualified technician person must install the heater. Follow all local codes.
WARNING:
Never install the heater.
·
in a bedroom or bathroom
·
in a recreational vehicle
·
where curtains, furniture, clothing, or other flammable objects are less than 42 inches
from the front, top, or sides of the heater
·
in high traffic areas
·
in windy or drafty areas
CAUTION:
This heater creates warm air currents. These currents move heat to wall surfaces next to heater.
Installing heater next to vinyl or cloth wall coverings or operating heater where impurities (such as tobacco
smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may discolor walls.
WARNING:
Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling, and
adjoining side and back walls.
INSTALLATION
IMPORTANT:
Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms
without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and
Ventilation, pages 7 through 9.
CHECK GAS TYPE
Use only the type of gas indicated on the plate. If your gas supply cannot meet that requirement, do not install
heater.
CLEARANCES TO COMBUSTIBLES
Carefully follow the instructions below. This fireplace is a freestanding unit designed to set directly on the floor
or on a mantel base.
IMPORTANT:
You must maintain minimum wall and ceiling clearances during installation. The minimum
clearances are shown in Figure 4, page 10. Measure from outermost point of fireplace.
