b) Two sets of 45 degree elbow offsets (bends in flexvent) within the vertical installation. From 0 to a maximum of 8 ft. of vent pipe can be used between elbows. c) Wall straps must be used to support offset pipe every 4'. This application will require that you first determine the roof pitch and use the appropriate venting components. General Maintenance Conduct an inspection of the venting system semi-annually. Recommended areas to inspect are as follows: 1. Check areas of the venting system which are exposed to the elements for corrosion. These will appear as rust spots or streaks and, in extreme cases, holes. These components should immediately be replaced. 2. Remove the cap and shine a flashlight down the vent. Remove any bird nests or other foreign material. 3. Check for evidence of excessive condensate, such as water droplets forming in the flex venting and subsequently dripping out at joints or seams. Condensate can cause corrosion of caps, pipe and fittings. It may be caused by having excessive lateral runs, or having exterior portions of the system exposed to cold weather. 4. Inspect joints to verify that no pipe sections or fittings have been disturbed and, consequently, loosened. Also, check mechanical supports, such as wall straps or plumbers’ tape for rigidity. Figure 9 Note that for steep roof pitches, the vent height must be increased. In high wind conditions, nearby trees, adjoining roof lines, steep pitched roofs, and other similar factors can result in poor draft, or down-drafting. In these cases, increasing the vent height may solve this problem. C L MIN. 24" 12" MIN. 24" MIN.

CAUTION: DISCONNECT REMOTE CONTROLS IF YOU ARE ABSENT FOR EXTENDED TIME PERIODS. THIS WILL PREVENT ACCIDENTAL FIREPLACE OPERATION. Installation of Alternate Surround Panel ON/OFF Switch An ON/OFF switch and wire assembly are provided. They are included in the instruction packet. Do not cut wire or insulation on metal edges. Note: Refer to surround panel installation section on page 15 for additional information on attachment. Contemporary Surrounds 1. Find the coiled low voltage wire assembly and ON/OFF switch located in the instruction packet. 2. Attach the flag terminal ends to the “TH/TP” and “TH” terminals on the front terminal block of the gas valve. See Figure 13. 3. Run the low voltage alternate switch wires up the back of the right or left surround panel. Then secure the wires with wire clips provided. See Figure 11. Figure 11 Insert ON/OFF switch into side panel then attach wire assembly from valve terminals. 4. Remove the switch knockout on the side surround panel, then install the ON/OFF switch. 5. Connect the low voltage wires from the gas valve to the ON/OFF switch. 6. Attach the surround panel assembly to the insert. Place the surround panel assembly against the face of the insert and align the lower retaining tabs with the notches on the insert sides. Lift the surround panel assembly slightly until the bottom return flange (top panel) is positioned over the top flange on the insert. This secures the surround panel assembly to the insert without screws. Traditional Cast Iron Surrounds 1. Find the coiled low voltage wire assembly and ON/OFF switch located in the instruction packet. 2. Attach the flag terminal ends to the “TH/TP” and “TH” terminals on the front terminal block of the gas valve. See Figure 13. WIRING FROM MILLIVOLT GAS VALVE ON/OFF SWITCH ASSEMBLY Right Side Installation Left Side Installation ON/OFF SWITCH ASSEMBLY Figure 12 Note: For right side leg installation, reverse switch position in bracket. 3. Run the low voltage alternate switch wires up the back of the right or left cast surround leg. Then secure them with the wire clips provided. 4. Install the switch bracket with screws as shown in Figure 12 to the back of the cast surround leg. 5. Install ON/OFF switch, and connect low-voltage wires from gas valve. 6. Attach cast surround panel assembly to the insert. Place the cast surround assembly against the face of the insert and align the lower retaining tabs with the notches on the insert sides. Lift the cast surround assembly slightly until the bottom return flange (top panel) is positioned over the top flange on the insert. This secures the cast surround assembly to the insert without screws.
