Page 10: Zero Clearance Fireplace Installation
Zero Clearance Fireplace Installation This insert may be installed in a masonry or factory built/zero clearance (ZC) fireplace. When installing in a ZC fireplace, the ZC grate must be removed and the ZC damper must be removed or secured open. The ZC doors, screen, refractory or masonry lining, baffles and smoke shelf may be removed if necessary to install the gas insert. However, do not cut or alter the fireplace components. The removal of any parts to facilitate installation must not alter the integrity of the inner or outer shells of the fireplace cabinet. Any parts removed must be replaceable if the insert is taken out of the fireplace or the fireplace must be clearly marked with the metal label that states: "This fireplace has been altered and is no longer safe to operate." The insert is designed to fit into a ZC fireplace with a minimum firebox height of 17-1/4" (438mm). To facilitate this the hood will need to be removed and discarded (Note: The screws should be replaced in the insert body). Installation of the flue collar is removable (see Flue Collar Connection). If the factory-built fireplace has no gas access hole(s) pro- vided, an access hole of 1-1/2" (37.5 mm) or less may be drilled through the lower sides or bottom of the firebox in a proper workmanship like manner. This access hole must be plugged with a non-combustible insulation after the gas... -
Page 11: Surround Panels Installation
Front Logs Install front logs on retainer slots. Figure 10 Place top log on pin. Top Log Ports Figure 11 Surround Panels Installation The Medina insert surround panels are made of heavy gage steel for durability and, if desired, for the ease of making an inside fit in the fireplace. 1. Remove the speed nuts (A in Figure 12) from the parts bag and install (with the flat surface forward) on the six holes in the surround brackets - three on each side of the insert (B in Figure 12). A flat bladed screwdriver may help in installing the nuts. 2. Install all surround panels and trim with the insert po- sitioned in the fireplace but a few inches in front of its final location. 3. Install the side surround panels by lining up the holes in the tabs on the side surround panels in front of the holes on the surround brackets. Next insert two slot- ted 1/4" truss screws for each side surround panel and secure loosely. 4. Fasten top surround panel with the remaining two truss screws. Tighten all six truss screws after adjusting the surround panels to eliminate space between side and top surround panels. -
Page 12: Gas Line Installation
Gas Line Installation After leveling, position the insert in the fireplace - holding it about six inches out from its final location. CAUTION: Specific hearth requirements apply (see Clear- ances to Combustibles). The Medina™ gas insert must be connected to the gas line in accordance with local codes and/or the National Fuel Gas Code, ANSI Z223.1 (In Canada, the current CAN/CSA B149.1 installation code). The insert comes with an 8" nipple attached to the supply side of the gas valve. After connect- ing the gas line, all joints in the line and connections at the valve should be checked for leaks before final positioning of the unit. Conduct a gas leakage test of the appliance piping and control system downstream of the shutoff valve in the supply line to the appliance.

Locate the pilot by looking over the top of the left front log. A blue flame will be seen when the pilot is lit. 6. Turn the gas control knob counter-clockwise to the "PILOT" position. 7. Push the knob all the way in and hold in that position. Immediately light the pilot by pressing the igniter button several times until pilot is lit. Continue to hold the knob in for about 30 seconds after the pilot is lit. Realease knob and it will pop back out. Pilot should remain lit. If it goes out, repeat steps 4-8 holding knob in an additional 15 seconds after pilot is lit. If knob does not pop out when released, stop and immediately call your service technician or gas supplier. If the pilot will not stay lit after several tries, turn the gas control knob to "OFF" and call your service technician or your gas supplier. 8. After pilot is lit, turn gas control knob counter-clockwise to "ON." Knob can only be turned to "ON" if the knob has popped out. 9. To turn burner on, turn "ON/OFF" rocker switch to "ON" or set the thermostat to the desired temperature above room temperature.

Page 15: Flame Color And Behavior
Flame Color and Behavior Your Medina™ gas insert is designed for maximum heating efficiency. Therefore, upon lighting of the main burner the flames will be semi-transparent or “bluish.” After 10-20 minutes of operation the logs will heat up and the flames will become a yellow/orange color. Adjusting the insert to cause the flames to turn orange sooner may result in poor combustion, sooting and a hazardous situation. See the drawing to the right showing proper flame appearance. When testing for proper operation - If an optional thermo- stat is installed adjust it to its highest temperature setting. Visually determine that main burner gas is burning properly: i.e., no floating, lifting or flashback. Adjust the primary air shutter(s) as required. Check for proper main burner opera- tion at both high and low flame. Burner Flame Appearance Soot above Soot at Flame Tip Flame Tip Dark Orange Flame Ports on Pan Burner Assembly No Blue Flame... -
Page 16: Operating Options
Operating Options The rocker switch on your Medina™ gas insert is used to turn the burner on and off while the pilot is on. The rocker switch can be installed in the hole in the right side of the top surround panel or in the hole in the panel to the left of the igniter button. The hole in the panel is covered by a label which must be carefully cut out before installing the rocker switch. The switch must be disconnected from the coil of wire to which it is attached, the plastic nut unscrewed from the back side of the switch and then the switch can be inserted into the hole at either location. If the switch is to be located in the surround, route the wire behind the igniter bracket and through the hole in the lower right side of the insert. Attach the three plastic adhesive wire restraints (found in the bag in the firebox) to the side surround panel. Feed the wire through these restraints and up to the switch. Care should be taken to ensure the wire does not come in contact with the hot surfaces of the firebox. Reconnect the wires to the switch. A wall-mounted switch, a millivolt wall thermostat, or a remote control, can be used to supplement the rocker switch. The gas valve is powered by millivolts generated by the pilot assembly. This millivolt system is very sensitive to electrical resistance, therefore, make sure all connections... -
