1.4 Installation
Codes
1.3 Warranty Refer to the limited warranty form in the "Literature Bag".
The indoor duct furnace models in this manual are design-certified to ANSI and CSA
standards by the Canadian Standards Association. All models are approved for instal-
lation in the United States and in Canada. All furnaces are approved for use with either
natural gas or propane. 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 charac-
teristics 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 NFPA/ANSI Z223.1 (latest edition). A Canadian installation
must be in accordance with the CSA B149.1 Natural Gas and Propane Installation
Code. 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.
These separated combustion units are designed and manufactured in accordance with
the ANSI definition of separated combustion. That definition reads, "Separated Com-
bustion System Appliance: A system consisting of an appliance and a vent cap(s) sup-
plied by the manufacturer, and (1) combustion air connections between the appliance
and the outside atmosphere, and (2) flue gas connections between the appliance and
vent cap, of a type(s) specified by the manufacturer but supplied by the installer, con-
structed so that, when installed in accordance with the manufacturer's instructions, air
for combustion is obtained from the outside atmosphere and flue gases are discharged
to the outside atmosphere."
Separated combustion units are designed to separate air for combustion and flue prod-
ucts from the environment of the building in which the unit is installed. Separated com-
bustion appliances are recommended for use in dust laden and some corrosive fume
environments.
