Resumen del manual
• The size of the roof hole framing dimensions depend on the pitch of the roof. There MUST BE a 1-inch (25.4mm) clearance from the vertical vent pipe to combustible materials. • Mark the roof hole accordingly. • Cover the opening of the installed vent pipes. • Cut and frame the roof hole. • Use framing lumber the same size as the roof rafters and install the frame securely. Flashing anchored to the frame must withstand heavy winds. • Continue to install concentric vent sections up through the roof hole (for inside vent installations) or up past the roof line until you reach the appropriate distance above the roof (for outside terminations). Figure 22. Proper Positioning, Leveling and Securing of a Fireplace NAILING TABS (BOTH SIDES) •Place the fireplace into position. •Level the fireplace from side to side and front to back. •Shim the fireplace with non-combustible material, such as sheet metal, as necessary. •Secure the fireplace to the framing by nailing or screwing. 19 Step 5. Installing the Optional Heat-Zone Kit Step 6 The Gas Control System Figure 23 HEAT-ZONE KNOCKOUTS Heat-Zone Kit 1. Remove the knockout from the top of the fireplace and discard it (see Figure 23). 2. Center the duct collar around the exposed hole and attach it to the fireplace with 3 screws. NOTE: Do this BEFORE final positioning of the fireplace. 3. Determine the location for the air register/fan housing assembly. Reference the Heat-Zone kit instructions for the remaining installations steps. WARNING: THIS UNIT IS NOT FOR USE WITH ! SOLID FUEL. The type of gas control system used with this model is Intermittent Pilot Ignition. Intermittent Pilot Ignition System This system includes millivolt control valve, standing pilot, thermopile/thermocouple flame sensor, and piezo ignitor. WARNING: 110-120 VAC MUST NEVER BE ! CONNECTED TO A CONTROL VALVE IN A MILLIVOLT SYSTEM. WARNING: CONTINUOUS 110-120 VAC SER ! VICE MUST BE WIRED DIRECTLY TO THE FIREPLACE JUNCTION BOX. Figure 24.

The Gas Supply Line NOTE: Have the gas supply line installed in accordance with local building codes by a qualified installer approved and/or licensed as required by the locality. (In the Commonwealth of Massachusetts installation must be performed by a licensed plumber or gas fitter). NOTE: Before the first firing of the fireplace, the gas supply line should be purged of any trapped air. NOTE: Consult local building codes to properly size the gas supply line leading to the 1/2 inch (13mm) hook-up at the unit. This gas fireplace is designed to accept a 1/2 inch (13 mm) gas supply line. To install the gas supply line: • A listed (and Commonwealth of Massachusetts approved) 1/2 inch (13mm) tee-handle manual shut-off valve and a listed flexible gas connector are connected to the 1/2 inch (13mm) inlet of the control valve. NOTE: If substituting for these components, please consult local codes for compliance. • Locate the gas line access hole in the outer left-side casing of the fireplace. • Insert the gas line through the access hole. Position the ball valve on the flex line to line up with the gas line. Attach the gas line. • When attaching the pipe, support the control so that the lines are not bent or torn. • After the gas line installation is complete, use a soap solution to carefully check all gas connections for leaks. WARNING: DO NOT USE AN OPEN FLAME TO ! CHECK FOR GAS LEAKS. • At the gas line access hole, use insulation to re-pack the space around the gas pipe. • Insert insulation from the outside of the fireplace and pack the insulation tightly to totally seal between the pipe and the outer casing. Step 8. Gas Pressure Requirements Pressure requirements for Heat-N-Glo gas fireplaces are shown in the table below. Pressure Natural Gas Propane Minimum 5.0 inches 11.0 inches Inlet Pressure w.c. w.c. Maximum Inlet 14.0 inches 14.0 inches Gas Pressure w.c. w.c. Manifold 3.5 inches 10.0 inches Pressure w.c. w.c. A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping is provided on the inlet and outlet side of the gas control for a test gauge connection to measure the manifold pressure. Use a small flat blade screwdriver to crack open the screw in the center of the tap. Position a rubber hose over the tap to obtain the pressure reading. The fireplace and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of one-half (1/2) psig (3.5 kPa). The fireplace must be isolated from the gas supply piping system by closing its individual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than one-half (1/2) psig (3.5 kPa). 21 Figure 25.
