Main burner orifice(s) and new gas conversion label are provided in conversion kit attached to manifold pipe. CONVERSION INSTRUCTIONS FROM NATURAL GAS TO (LP) PROPANE GAS 1. Turn OFF gas supply and electrical power to fireplace. 2. Remove lower front panel. 3. Unscrew regulator stem from gas valve and reverse regulator stem to the propane gas position and screw stem back into gas valve. The propane gas arrow will be pointing at the gas valve in the propane gas position. See Figure 37. 4. Open four (4) door latches in order to pivot open the front door. 5. Remove logs from fireplace. Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. 6. Disconnect caps and plugs on flame sensor and hot surface ignitor. 7. Remove log plate from interior of fireplace by removing twelve (12) screws. See Figure 47. 8. Remove front burner (one (1) screw). 9. Use 3/8” socket or wrench to remove natural gas front burner orifice marked 1.50 from orifice fitting. Replace with propane gas front burner orifice marked 1.10 into orifice fitting. 10. Remove natural gas front burner bushing from throat (Venturi) of front burner. See Figure 38. 11. Replace front burner with one (1) screw from Step 8. 12. Remove rear burner (one (1) screw). 13. Use 3/8” socket or wrench to remove natural gas rear burner orifice marked 2.35 from orifice fitting. Replace with propane gas rear burner orifice marked 1.45 into orifice fitting. 14. Replace rear burner with one (1) screw from Step 12. 15. Connect caps and plugs on flame sensor and hot surface ignitor. 16. Install log plate into fireplace with twelve (12) screws from Step 7. 17. Replace logs into fireplace. Refer to page 12, Log Placement, for correct placement of logs. 18. Close front door by securing four (4) door latches. 19. Replace front panel. 20. Place Natural gas main burner orifices and front burner bushing into conversion kit. Attach conversion kit to manifold pipe. Attach gas conversion label adjacent to fireplace nameplate indicating that the fireplace was converted to Propane gas. 21. Turn ON gas supply to Fireplace and check all gas connections for leaks with soap solution, watching for bubbles on all gas connections. 22. Turn ON electrical power to fireplace and turn on fireplace to verify proper operation. It may take several tries for ignition to completely purge all the air from the gas line. REGULATOR STEM REMOVE BUSHING FOR LP GAS Figure 37 Figure 38 AUTOMATIC HUMIDIFIER OPERATION Figure 39 Most gas heaters dry out the air in the room. The Mantis has ingeniously solved this problem with an Automatic Humidifier. Gas contains moisture which is normally expelled out the flue or chimney after combustion. But the Mantis is so efficient by taking 92% of the heat out of the burnt gases that the moisture drops out and condenses in the back of the heater. This water is collected in a tank which is then pumped up to a stainless steel condensate tray, where it evaporates in the stream of hot air which is blowing into your home. Air humidity is automatically restored! 1. The amount of condensate build up in the water sump is dependent on outside temperature, length and height of the flue pipe. The automatic humidifier can operate from approximately 10 minute to 6 hour intervals, depending on ambient temperature, style and type of flue. Long single vertical flues can cause the humidifier to come on more often depending on heater settings. 2. When the automatic humidifier is engaged and is transferring the condensate into the holding tank, a hissing sound may be noticeable. This occurs when the condensate enters the holding tank and is quite normal. The duration of the sound may vary from 3 to 30 seconds until the holding tank has been filled with the condensate. 3. When the automatic humidifier pump comes on to pump condensate into the stainless steal tray (located on the top of the heater), the L.E.D. light (Page 28, Figure 34B) on the front panel will light up and flash while the condensate pump is operating, and then extinguish after the pump has stopped operating. This means water has been pumped into the tank, and the automatic humidifier operation will begin. 22618-4-1106 Page 33 OPTIONAL REMOTE CONTROL THERMOSTAT An optional programmable Remote Control Thermostat can be fitted to the heater at the factory when ordered or even after the heater has been installed. See your Mantis dealer for correct type. Installation: The Remote Control can be installed by the owner of the heater if required. The Remote Control is a battery operated device, which requires a small amount of low voltage wiring. A wiring loom package is supplied by Empire Comfort Systems, Inc. which simply attaches onto the junction box. See Figure 35. Remove blue jumper wire from junction block and save for furture use. From the remote control receiver, cut and strip one black wire 1/4” terminal from wir...
