Follow installation instructions CAREFULLY to avoid 
creating unsafe conditions. All wiring should be done 
and checked by a qualified electrician, using copper 
wire only. All external wiring must conform to 
applicable local codes, and to the latest edition of the 
National Electric Code 
ANSI/NFPA No. 70.

All gas connections should be made and leak-tested by 
a suitable qualified individual, per instructions in this 
manual. Also follow procedures listed in 

“Gas 

Equipment Start-Up,” p. 30

.

Use only the fuel for which the duct furnace is 
designed (see rating plate). Using LP gas in a heater 
that requires natural gas, or vice versa, will create the 
risk of gas leaks, carbon monoxide poisoning and 
explosion.

Important:

Do not attempt to convert the duct 
furnace for use with a fuel other than 
the one intended. Such conversion is 
dangerous, as it could create the risks 
listed previously.

Use only the fuel for which the heater is designed (see 
rating plate). Using LP gas in a heater that requires 
natural gas, or vice versa, will create the risk of gas 
leaks, carbon monoxide poisoning and explosion.

Make certain that the power source conforms to the 
electrical requirements of the heater.

Do not depend upon a thermostat or other switch as 
a sole means of disconnecting power when installing 
or servicing heater. Always disconnect power at main 
circuit breaker as described above. Failure to do so 
could result in fatal electric shock.

Special attention must be given to any grounding 
information pertaining to this heater. To prevent the 
risk of electrocution, the heater must be securely and 
adequately grounded. This should be accomplished by 
connecting a grounded conductor between the 
service panel and the heater. To ensure a proper 
ground, the grounding means must be tested by a 
qualified technician. 

Do not insert fingers or foreign objects into the heater 
or its combustion air moving device. Do not block or 
tamper with the heater in any manner while in 
operation or just after it has turned off, as some parts 
may be hot enough to cause injury.

This heater is intended for general heating 
applications ONLY. It must NOT be used in potentially 
dangerous locations such as flammable, explosive, 
chemical-laden or wet atmospheres. 

In cases in which property damage may result from 
malfunction of the heater, a backup system or a 
temperature sensitive alarm should be used.

The open end of gas piping systems being purged shall 
not be discharged into areas where there are sources 
of ignition or into confined spaces UNLESS 

precautions are taken as follows: 1) by ventilation of 
the space, 2) by control of purging rate, 3) by 
elimination of all hazardous conditions. All 
precautions must be taken to perform this operation in 
a safe manner!

Unless otherwise specified, the following conversions 
may be used for calculating SI unit measurements:
