Installation should be done by a qualified agency in accordance with the instructions
in this manual and in compliance with all codes and requirements of authorities hav-
ing jurisdiction. The instructions in this manual apply only to Model F and Model B unit
heaters.
The gas-fired unit heaters covered in this manual are design-certified by the Canadian
Standards Association (CSA) to ANSI Z83.8 and CSA 2.6 for industrial/commercial
installations in the United States and Canada. All heaters are available for use with
either natural or propane gas. The type of gas, the firing rate, and the electrical char-
acteristics are on the unit rating plate.
These units must be installed in accordance with local building codes. In the absence
of local codes, in the United States, the unit must be installed in accordance with the
National Fuel Gas Code ANSI Z223.1 (latest edition). A Canadian installation must be
in accordance with the CSA B149 Installation Codes for Gas Burning Appliances and
Equipment (latest edition). These codes are available from CSA Information Services,
1-800-463-6727. Local authorities having jurisdiction should be consulted before instal-
lation is made to verify local codes and installation procedure requirements.
Special Installations (Aircraft Hangars/Garages)
Installations in aircraft hangars should be in accordance with ANSI/NFPA No. 409 (lat-
est edition), Standard for Aircraft Hangars; in public garages in accordance with ANSI/
NFPA No. 88A (latest edition), Standard for Parking Structures; and for repair garages
in accordance with ANSI/NFPA No. 88B (latest edition), Standard for Repair Garages.

2.1 General Recommendations
WARNING: Avoid installing a unit heater in extremely drafty
areas. Extreme drafts can shorten the life of the heat exchanger
and/or cause safety problems.
For best results, the heater should be placed with certain rules in mind. In general, a
unit should be located from 8 to 12 feet (2.4-3.7M) above the floor. Units should always
be arranged to blow toward or along exposed wall surfaces, if possible. Where two or
more units are installed in the same room, a general scheme of air circulation should
be maintained for best results.
Suspended heaters are most effective when located as close to the working zone as
possible, and this fact should be kept in mind when determining the mounting heights
to be used. However, care should be exercised to avoid directing the discharged air
directly on the room occupants.
Partitions, columns, counters, or other obstructions should be taken into consideration
when locating the unit heater so that a minimum quantity of airflow will be deflected by
such obstacles.
