*A CSA/AGA certifi ed equipment shutoff valve with
1/8” NPT tap is an acceptable alternative to test gauge
connection. Purchase a CSA/AGA certifi ed equipment
shutoff valve from your dealer.
LOCATING HEATER
This heater is designed to be mounted on the wall. The
heater can also be located on a non-combustible fl oor,
away from a wall by using the fl oor mounting stands in-
cluded with the heater. If installed on combustible fl oor-
ing such as carpeting, tile or other combustible material
other than wood fl ooring, the heater must be placed on
a wood panel the full width and depth of the appliance.
For convenience and effi ciency, install the heater:
•
Where there is easy access for operation,
inspection, and service
•
In the coldest part of the room.
•
If planning to use fan, locate heater near an
electrical outlet.
CAUTION:
If you install the heater in a home garage:
Heater pilot and burner must be at least 18 inches
above fl oor . Locate heater where moving vehicle will
not hit it.
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
covering or operating heater where impurities (such
as tobacco smoke, aromatic candles, cleaning fl uids,
oil or kerosene lamps, etc.) are present in the air may
discolor walls.
WARNING:
Never install the heater:
•
In a bedroom (RD20NGT, RD30NGT,
BF20NGT or BF30NGT)
•
In a recreational vehicle ·.
•
Where curtains, furniture, clothing, or other
fl ammable objects are less than 36 inches from
the front, top, or sides of the heater.
• As
a
fi replace insert
• In
high-traffi c areas
•
In windy or drafty areas
WARNING:
Heater must be mounted to maintain
the minimum clearances shown in Figure 4. If
possible, provide greater clearances from the fl oor,
ceiling, and joining walls.
WARNING:
Rework worksheet, adding the space
of the adjoining unconfi ned space. The combined
space must have enough fresh air to supply all ap-
pliance in both spaces.
Ventilation from Outdoors
If necessary provide extra fresh air by using ventila-
tion grills or ducts. Connect these items directly to the
outdoors or spaces open to the outdoors. These include
attics* and crawl spaces. Follow the National Fuel Gas
Code NFPA 54/ ANSI Z223.1, Section 5.3, Air for Com-
bustion and Ventilation for required size of ventilation
grills or ducts.
*IMPORTANT:
Do not provide openings for inlet or
outlet into attic. If attic has a thermostat-controlled
power vent, heated air entering the attic will activate
the power vent.
IMPORTANT:
Vent-free heaters add moisture to
the air. Although this is benefi cial, installing heater
in rooms without enough ventilation air may cause
mildew to form from too much moisture. See Fresh
Air for Combustion and Ventilation, pages 4 through
6.
