Attention—Critical Points to Remember!
•
Propane (LP) gas has a distinctive odor. Learn to recognize these odors.
(Reference Fuel Gas Odor and Odor Fading sections above.
•
Even If you are not property trained in the service and repair of the heater,
ALWAYS be consciously aware of the odors of propane (LP) gas and natural
gas.
•
If you have not been properly trained in repair and service of propane (LP)
gas then do not attempt to light heater, perform service or repairs, or make
any adjustments to the heater on the propane (LP) gas fuel system.
For the U.S. and/or Canada, the installation of this appliance must
comply with local and/or Provincial codes or, in the absence of these codes,
•
With the (U.S.) National Fuel Gas Code, ANSI Z223.1 – Latest Edition,
AND with the (U.S.) Standard for the Storage and Handling of Liquified
Petroleum Gases, ANSI/NFPA 58, OR
•
With the current (Canadian) CAN/CGA B149.1 AND B149.2
INSTALLATION CODES.
This heater (including hose and regulator assembly) must be inspected
before each use and at least annually by a qualified service person. If
the hose for Model DXH45LP shows evidence of excessive abrasion or
wear, or if the hose is cut, it must be replaced prior to the heater being
put into operation. The replacement hose assembly shall be that specified
by the manufacturer. See the parts list.
The minimum ambient temperature rating for this heater is 20 degrees F.
This heater incorporates a “Tip Over” switch which automatically shuts

Installation Instructions
WARNING: RISK OF ASPHYXIATION
•
Do not use in unventilated areas.
•
The flow of combustion and ventilation air must not be obstructed.
•
Proper ventilation air must be provided to support the combustion air
requirements of the heater being used.
•
Refer to the specification section of the heater’s manual, heater dataplate,
or contact the factory to determine combustion air ventilation
requirements of the heater.
•
Lack of proper ventilation air will lead to improper combustion.
•
Improper combustion can lead to carbon monoxide poisoning leading to
serious injury or death. Symptom of carbon monoxide poisoning
can include headaches, dizziness and difficulty in breathing.
WARNING
Never use a fork lift truck type cylinder.
•
The odorant in propane (LP) gas and natural gas is colorless and the
intensity of its odor can fade under some circumstances.
•
If there is an underground leak, the movement of gas through the soil can
filter out the odorant.
•
Propane (LP) gas odor may differ in intensity at different levels. Since
Propane (LP) gas is heavier than air, there may be more odor at lower levels.
•
Always be sensitive to the slightest gas odor. If you continue to detect any
gas odor, no matter how small, treat it as a serious leak. Immediately go into
action as discussed previously.
•
A periodic sniff test around the heater or at the heater’s joints; i.e. hose,
connections, etc., is a good safety practice under any conditions. If
you smell even a small amount of gas, CONTACT YOUR FUEL GAS
SUPPLIER IMMEDIATELY.
