Note:
Home owners generally prefer to operate their heater
with the chimney damper closed. This will put all the heat into
the room. However, there may be times you will desire the full
flames of the Hi heat setting but will find the heat output
excessive. You can open the chimney damper (if you have one)
fully or partially to release some of the heat.
WARNING: Damper handle will be hot if heater has
been running.
1. STOP! Read the safety information on page 18, column 2.
2. Make sure equipment shutoff valve is fully open.
3. Turn control knob clockwise

4. Wait five (5) minutes to clear out any gas. Then smell for
gas, including near the floor. If you smell gas, STOP! Fol-
