Propane gas can lose its scent. In case of a leak, LP/
Propane gas will settle close to the floor and may be difficult
to smell. An LP/Propane leak detector should be installed
in all LP applications.
Use only the type of gas approved for use with this furnace.
Refer to unit nameplate.

In the USA, installation of gas furnaces must conform with
local building codes. In the absence of local codes, units
must be installed according to the current National Fuel Gas
Code (ANSI Z223.1/NFPA 54). The National Fuel Gas Code
is available from the
American National Standards
Institute, Inc., 11 West 42nd Street, New Your, NY 10036 .
Installed Locations
In Canada, installation must conform with current National
Standard of Canada CSA-B149 Natural Gas and Propane
Installation Codes, local plumbing or waste water codes and
other applicable local codes.
The furnace is designed for installation clearances to
combustible material as listed on the unit nameplate and in
the tables in Figures 10 and 11. Accessibility and service
clearances must take precedence over fire protection
clearances.

shall not be installed directly on carpeting, tile, or other
combustible material other than wood flooring.
Improper installation, adjustment, alteration, service or
maintenance can cause property damage, personal injury
or loss of life. Installation and service must be performed
by a licensed professional installer (or equivalent), service
agency or the gas supplier.
