WARNING
• FURNACES USING PROPANE GAS ARE DIFFER-
ENT FROM NATURAL GAS MODELS. A NATURAL
GAS HEATER WILL NOT FUNCTION SAFELY ON
PROPANE AND VICE VERSA. CONVERSIONS OF
HEATER GAS TYPE SHOULD ONLY BE MADE BY
QUALIFIED INSTALLERS USING FACTORY SUP-
PLIED COMPONENTS. THE FURNACE SHOULD
ONLY USE THE FUEL TYPE IN ACCORDANCE
WITH LISTING ON RATING PLATE. ANY OTHER
FUEL USAGE WILL RESULT IN DEATH OR SERI-
OUS PERSONAL INJURY FROM FIRE AND/OR EX-
PLOSION.
• BOTH NATURAL GAS AND PROPANE HAVE AN
ODORANT ADDED TO AID IN DETECTING A GAS
LEAK. SOME PEOPLE MAY NOT PHYSICALLY BE
ABLE TO SMELL OR RECOGNIZE THIS ODORANT.
IF YOU ARE UNSURE OR UNFAMILIAR WITH THE
SMELL OF NATURAL GAS OR PROPANE, ASK
YOUR LOCAL GAS SUPPLIER. OTHER CONDI-
TIONS, SUCH AS “ODORANT FADE,” WHICH
CAUSES THE ODORANT TO DIMINISH IN INTEN-
SITY, CAN ALSO HIDE, CAMOUFLAGE, OR OTH-
ERWISE MAKE DETECTING A GAS LEAK BY
SMELL MORE DIFFICULT.
• UL OR CSA RECOGNIZED FUEL GAS DETECTORS
ARE RECOMMENDED IN ALL ENCLOSED
PROPANE AND NATURAL GAS APPLICATIONS
WHEREIN THERE IS A POTENTIAL FOR AN EXPLO-
SIVE MIXTURE OF FUEL GAS TO ACCUMULATE.
FUEL DETECTOR INSTALLATION SHOULD BE IN
ACCORDANCE WITH THE DETECTOR MANUFAC-
TURER’S RECOMMENDATIONS AND/OR LOCAL
LAWS, RULES, REGULATIONS, OR CUSTOMS.
• BEFORE ATTEMPTING TO LIGHT THE FURNACE,
MAKE SURE TO LOOK AND SMELL FOR GAS
LEAKS. USE A SOAPY SOLUTION TO CHECK ALL
GAS FITTINGS AND CONNECTIONS.
BUBBLING AT A CONNECTION INDICATES A LEAK
THAT MUST BE CORRECTED. WHEN SMELLING TO
DETECT A GAS LEAK, BE SURE TO ALSO SNIFF
NEAR THE FLOOR. PROPANE GAS IS HEAVIER
THAN AIR AND TENDS TO COLLECT AT LOWER
LEVELS MAKING IT MORE DIFFICULT TO SMELL AT
NOSE LEVEL. NATURAL GAS IS LIGHTER THAN AIR
AND WILL RISE, POSSIBLY ACCUMULATING IN
HIGHER PORTIONS OF THE STRUCTURE.
• IF A GAS LEAK IS PRESENT OR SUSPECTED:
- DO NOT ATTEMPT TO FIND THE CAUSE YOUR-
SELF.
- NEVER USE AN OPEN FLAME TO TEST FOR GAS
LEAKS. THE GAS CAN IGNITE RESULTING IN
DEATH, PERSONAL INJURY, OR PROPERTY
DAMAGE.
- DO NOT TRY TO LIGHT ANY APPLIANCE.
- DO NOT TOUCH AND ELECTRICAL SWITCH.
- DO NOT USE ANY PHONE IN YOUR BUILDING.
- LEAVE THE BUILDING IMMEDIATELY AND CALL
THE GAS SUPPLIER FROM A NEIGHBOR’S
PHONE. FOLLOW THE GAS SUPPLIER’S INTRUC-
TIONS.
- IF YOU CANNOT REACH YOUR GAS SUPPLIER,
CALL THE FIRE DEPARTMENT.
- DO NOT RETURN TO THE BUILDING UNTIL AU-
THORIZED BY THE GAS SUPPLIER OR FIRE DE-
PARTMENT.
• SHOULD OVERHEATING OCCUR OR THE GAS
SUPPLY FAIL TO SHUT OFF, TURN OFF THE MAN-
UAL GAS CONTROL VALVE TO THE FURNACE.
• CONSULT WITH THE LOCAL BUILDING DEPART-
MENT AND FUEL GAS SUPPLIER BEFORE IN-
STALLING THE HEATER:
- THE INSTALLATION AND PURGING OF GAS PIP-
ING MUST CONFORM TO LOCAL CODES, UTIL-
ITY COMPANY REQUIREMENTS, AND THE
LATEST EDITION OF NATIONAL FUEL GAS
CODE (NFGC) - ANSI Z223.1/NFPA 54, OR CSA
B149.1, NATURAL GAS AND PROPANE INSTAL-
LATION CODE.
- LP FURNACES SHOULD NOT BE INSTALLED
BELOW GRADE (IN A BASEMENT FOR EXAM-
PLE) IF SUCH INSTALLATION IS PROHIBITED BY
FEDERAL, STATE, PROVINCIAL, AND/OR LOCAL
LAWS, RULES, REGULATIONS, OR CUSTOMS.
- INSTALLATION OF A GAS PRESSURE REGULA-
TOR MAY BE REQUIRED IN THE GAS SUPPLY
LINE. THE REGULATOR SHOULD NOT EXCEED
THE MAXIMUM SUPPLY PRESSURE LISTED ON
THE FURNACE RATING PLATE. DO NOT USE AN
INDUSTRIAL-TYPE GAS REGULATOR.
- FOLLOW ALL LOCAL CODES AND SECTION 8.3
OF NFGC WITH REGARD TO PURGING OF GAS
PIPING TO ENSURE THAT THE AIR AND/OR FUEL
GAS IN THE GAS PIPING IS PROPERLY VENTED
TO A LOCATION WHERE AN EXPLOSIVE MIX-
TURE CANNOT ACCUMULATE.
