Series 100, Model F gas-red, gravity-vented unit heaters are designed for 80% thermal efciency
and are designed for use with natural or propane gas, as specied, in sizes from 25,000 to 400,000 BTUH gas
input.
Model F unit heaters are designed for ceiling suspension with a propeller fan for air delivery.
A terminal strip connector facilitates eld connection to a remote 24-volt thermostat for automatic operation.
Each unit is provided with a fan control and all required limit safety controls, including an energy cutoff (ECO)
device and a blocked vent switch.
These units are approved for installation in The United States and Canada by the Canadian Standards As-
sociation (CSA).
NOTE: When installing gravity vented appliances check local and state codes for requirements. Some states require the addition of spark
pilot Option AH2 or AH3.
