WIRING The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 or Canadian Electrical Code, CSA C22.1, if an external electrical source is utilized. This appliance is equipped with a three-prong [grounding] plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug.
GENERAL INFORMATION Over Temperature Cut Out The Mantis Power-Vent High-Efficiency Fireplace is protected against overheating with a high temperature 80°C (176°F) cut off switch to protect the heat exchanger, plastic sump and flue fan. The high temperature cut off switch will automatically switch off the gas supply to the heater, if the temperature in the room where the heater is located reaches approximately 28°C (82.4°F). The heater will go into lock out mode.
MAINTENANCE Note: Your appliance should be inspected, serviced and checked annually by a qualified service person to ensure that your appliance is operating safe and efficiently. Should you detect any abnormality in the operation of your appliance call a qualified service person who has been trained and approved to inspect and service the appliance. This may be your installer or dealer (routine service is not covered under warranty). Glass Cleaning It will be necessary to clean the glass periodically.

MAIN CONVECTION FAN The main convection fan in the heater should be checked, serviced and cleaned annually by a qualified service person to ensure that your appliance is operating efficiently. Note: If the main convection fan becomes clogged with lint and dust an over-temperature situation will occur through the heater exchange system and the over-temperature safety switch will stop the heater from operating. HEAT EXCHANGER The heat exchanger of the unit is located at the rear of the heater.
RESETTING THE HEATER There are a number of reasons why sometimes the heater will switch itself off and is the correct thing for the heater to do in certain situations (i.e. overheating, power failure or dips, windy conditions, pump failure, partial or full blockage of flue pipe or no gas. All of these operations are monitored by the electronic control box inside the heater, which is heat sensitive, pressure switch sensitive, flame sensitive and water sensitive.
