Page 6: Pre-Installation
Pre-Installation Features Installation Options Residential Vented vertical and horizontal Manufactured (mobile) home Natural gas (NG) or propane (LP) Bedrooms Optional wall-mounted or remote thermostat Venting This stove can be vented with Security™ Secure Vent™ pipe*. Coaxial pipe diameters are 6-5/8” outer and 4” inner. The combustion air for this stove is drawn from outside the house through the outer DV (direct vent) pipe. Room air is not required for combustion. When planning your installation, select the correct length of vent pipe for your particular requirements. Determine the minimum clearance to combustibles from the rear of the unit to the wall. It is also important to note the thickness of the wall. Before cutting the vent hole through the wall make sure that ALL vent and termination clearances (see Page 17) will be met. Electrical The standard fan motor requires 120 Volts AC for operation. The stove is not dependent on the fan or an outside electri- cal supply to operate. WARNING - Electrical Grounding... -

This appliance will not function properly unless the required gas pressure is supplied. See the table on this page for gas pressure requirements. Two pressure taps are provided on the stove’s valve to check gas pressures. To access the taps, remove the four socket head screws from the valve control panel.

Page 19: Operating Instructions
Operating Instructions Pre-Lighting Checklist: Be sure to check these items before the initial lighting of the stove: The stove gas label corresponds to the gas supply available - that is “natural gas” for natural gas or “LP gas” for LP gas. Gas pressure has been checked carefully - see Page All gas fittings have been checked for leaks. All clearances to combustibles have been met - see Page 8. All combustible materials have been removed from area in front of the stove. All vented areas of the stove are unobstructed. House is ventilated to clear initial paint curing odors - see Page 21. -
Page 20: Flame Color And Behavior
GAS CONTROL ON/OFF Figure 29 Flame Color and Behavior Your stove is designed for maximum heating efficiency. Therefore, upon lighting of the main burner the flames will be semitransparent or “bluish.” After 10-20 minutes of operation, the logs will heat up and the flames will become a yellow/orange color. Adjusting the stove 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... -

Page 22: Operating Options
Operating Options Your stove comes equipped with an “On/Off” rocker switch used to turn the burner on and off while the pilot light is on. The switch is a round rocker switch located behind the main control panel door. 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 are tight, clean and free from corrosion. Do not splice any millivolt wires. Consult the table below to determine the proper gage of wire for the thermostat or wall switch connections. This table refers to the total length of the wire (out to the switch and back). The thermostat must be a millivolt type. A 24-volt furnace thermostat will not work. Never hook up household current... -

CAUTION: Do not attempt to open the main door while the unit is burning or still hot. Let the unit cool before opening the door. To replace the door: 1. Shut off the main burner using the rocker switch. 2. Shut off the pilot flame by turning the pilot knob clock- wise to “OFF.” Figure 35 3. Facing the stove pull open the left side door and open the right side door by removing the socket head cap screw located underneath the door near the front of the stove. 4. With both doors open, remove the four socket head cap screws, two on each side, securing the top. Lift and remove the top of the stove. 5. Unlatch main door and lift straight up off of the locating hinge pins. -
Page 26: Fuel Conversion
Fuel Conversion Converting the stove between natural gas (NG) and propane (LP) can be accomplished by either changing the cassette (valve and pilot assembly) or installing a conversion kit (regulator, burner orifice and repositioning the slide orifice of the pilot). Only a qualified service technician should perform the conversion. Conversion Kit Please see instructions provided with conversion kit. Cassette Removal CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. -
Page 27: Troubleshooting
Troubleshooting NOTE: When troubleshooting the gas control system, be sure the external gas shut off valve, located at the gas sup- ply inlet is in the “ON” position. IMPORTANT: Call your gas supplier or plumber for additional help with any gas control problem. Valve system troubleshooting should only be accomplished by a qualified service technician. SYMPTOM PROBABLE CAUSE Thin black coating Improper log or ember (soot) forms on the placement. viewing glass, logs, or firebox. Blocked flue. Improper air shutter setting. -
