GENERAL 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 having jurisdiction. The instructions in this manual apply to the heater model shown below.

Heaters are available for use with either natural or propane gas. The type of gas, the firing rate, and the electrical characteristics are on the unit rating plate. A Model CAUA heater requires installation of an inlet air duct or an optional inlet air base and a supply duct or an optional discharge plenum. This heater may be installed as a separated-combustion system (taking combustion air from outside) or as a power-vented system (taking combustion air from the space where the heater is installed). Mfg No. 164771, Page 1 GENERAL (Cont'd) Separated-combustion units are designed to separate the air for combustion and the flue products from the environment of the building in which the unit is installed. Separated-combustion appliances are recommended for use in dust laden and some corrosive fume environments or in buildings with negative pressure (up to .15" w.c.). If installed as a separated-combustion system, the heater must be equipped with both combustion air and exhaust piping to the outdoors. All Model CAUA heaters must be vented to the outdoors.
