The Reznor® Series 100, Model F
Reznor® Series 100, Model F gas-fired, gravity-vented unit heaters are designed for 80% thermal efficiency and are designed for use with natural or propane gas, as specified, 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 field 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 Association (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.
The Energy Policy Act of 2005 mandated that beginning August of 2008, no Gravity Vented Unit
Heaters may be sold without an Intermittent Ignition Device (No Standing Pilot- Spark Ignition
Only) AND, (either an automatic shutoff vent damper or a power vent exhaust). Your state may
have already enacted this restriction in their local codes. Please take note of this when placing
orders for gravity vented units.
