1.4 Installation
Codes
The duct furnaces covered in this manual are design-certified by the Canadian Stan-
dards Association to ANSI Z83.8a and CSA 2.6 for use with either natural or propane
gas. The type of gas for which the furnace is equipped and the correct firing rate are
shown on the rating plate attached to the unit. Electrical characteristics are shown 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 (latest edition). A Canadian installation must be in accordance
with the CAN/CGA B149.1 and B149.2 Installation Code for Gas Burning Appliances
and Equipment. These codes are available from CSA Information Services, 1-800-463-
6727. Local authorities having jurisdiction should be consulted before installation 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.
ANSI/NFPA-88 (latest edition) specifies overhead heaters must be installed at least

2.0 Furnace
Location
2.1 General Recommendations
A duct furnace is designed for connection to an inlet and an outlet duct and depends
on an external air handler. Location must comply with the clearances listed in Para-
graph 4.2. There are a variety of factors, such as system application, building structure,
dimensions, and weight, that contribute to selecting the location. Read the installation
information in this manual and select a location that complies with the requirements.
WARRANTY: Warranty is void if......
a. Furnaces are used in atmospheres containing flammable vapors or atmospheres
containing chlorinated or halogenated hydrocarbons or any contaminant
(silicone, aluminium oxide, etc.) that adheres to the spark ignition flame sensing
probe.
b. Wiring is not in accordance with the diagram furnished with the heater.
c. Unit is installed without proper clearances to combustible materials or located
in a confined space without proper ventilation and air for combustion. (See
Paragraphs 2.2 and 4.2.)
d. Furnace air throughput is not adjusted within the range specified on the rating
plate.
e. Duct furnace is installed in a process or drying application without factory
authorization. (Any use in a process or drying application voids agency
certification.)
WARNING
These duct furnaces are not certified or approved for use in drying or process applications. If a
duct furnace is to be used in a drying or process application, contact the factory for application
guidelines and manufacturer's authorization. Without factory authorization, the warranty is void,
and the manufacturer disclaims any responsibility for the duct furnace and/or the application.
WARNING
To ensure safety, follow lighting instructions located on he outlet box cover.
WARNING
Avoid installing a furnace in extremely drafty areas. Extreme drafts can
shorten the life of the heat exchanger and/or cause safety problems.
