[. . . ] Refer to the appliance manufacturer's specifications for vent termination location. The location of the vent termination must be installed with the manufacturer's recommendations, and/or local codes that are applicable. In the USA according to the latest version of the National Fire Protection Association NFPA-31, National Fuel Gas Code ANSI Z223. 1. Where requirements for venting standards differ the most stringent standard shall apply. [. . . ] After determining the location of the venting system termination (See Diagram A), cut a hole in the wall sized according to "L" dimension in Table 1. (See Figure 1) Seal the back side of the base plate around the outer pipe of the vent termination with a bead of high temperature silicone sealant. (See Figure 2 ­ Side View Figure 2) Mount the vent termination through the wall, keeping the outer pipe centered in the hole. (See Figure 1) Fasten the vent termination to the outside wall with appropriate fasteners. Seal the edges of the vent termination base plate to the wall with a high-temperature silicone sealant. 2. Fasten the backing plate to the inside wall with appropriate fasteners. (See Figure 2) DO NOT BLOCK the intake or exhaust openings, or the intake access panel on the vent termination body. Wood or vinyl siding should be cut so that the unit mounts directly on the wallboard to provide a stable support. If the siding is greater than 1/2" thick use a spacer plate or board behind the vent termination mounting plate. (See Figure 2) Page 2 INSTALLATION OF THE VENT TERMINATION COMBUSTION AIR TEE 1. Assemble the combustion air tee assembly body to the vent termination outer pipe, and rotate to the desired position. It is intended as a guide to aid in determining that the venting system is properly installed and is in a safe condition for continuous use. This procedure should be recognized as a generalized procedure which cannot anticipate all situations. Accordingly, in some cases, deviation from this procedure may be necessary to determine safe operation of the equipment. If it is determined that a condition exists which could result in unsafe operation, the appliance should be shut off and the owner advised of the unsafe condition. Corrections must be made before the appliance is put into continuous operation. Visually inspect the venting system for proper size and determine that there is no flue gas spillage, blockage, restriction, leakage, corrosion, or other deficiency which could cause an unsafe operation. Follow the lighting instructions and adjust thermostat so appliance will operate continuously. Determine that the burner is operating properly and that the burner ignition operates satisfactorily by interrupting and reestablishing the electrical power of the appliance in any convenient manner. Test the burner safety device to determine if it is operating properly by disconnecting the flame safety circuit. Test for spillage at the burner inlet air location around the VRV after 5 minutes of operation. Use a draft gauge, flame of a match or candle, or smoke from a cigarette, cigar or pipe. [. . . ] Install the supplied self-drilling, self-tapping anchoring screws through the 4 holes in the appliance clamp into the appliance collar (Figure 6). After testing and burner adjustments have been made, apply sealant to the supplied 3/8" sampling port plug screw and install the screw in the sampling port (Figure 6). Maintain the appliance manufacturer's clearances to combustibles. If the appliance collar is within 18" of combustible material, wrap minimum 1-1/2" ceramic insulation (installer-supplied) around the exposed portion of the termination inner pipe and appliance adapter (Figure 10).
