User manual FIELD CONTROLS 46483500

[. . . ] Safety inspection of a venting system should be performed before and after installing a venting system on an existing or new appliance. Procedures to follow are the latest version of those recommended by the National Fuel Gas Code, ANSI Z223. 1, UL-726, NFPA31, CSA B139, CSA B140. 0. 03 appliance manufacturer's recommendations, or refer to the General Installation Inspection section of this manual. Plan the vent system layout before installation to avoid the possibility of accidental contact with concealed wiring or plumbing inside walls. INSTALLATION OF FDVS DIRECT VENT SYSTEM INSTALLATION OF THE VENT TERMINATION (c) (a) (b) (e) (c) (c) (g) Diagram A 1. [. . . ] 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. Attach the tee assembly body to the vent termination outer pipe with at least 3 sheet metal screws evenly spaced apart (not included). After completing assembly of the vent pipe to the termination inner pipe (Fig. 4), apply the supplied high temperature sealant to the cover pan around the inner pipe, around the joint between the collar and the Tee assembly, and seal or tape the joint from the FDVS Termination to the Tee assembly. NOTE: The tee may be rotated into any position so that the collar is in a convenient orientation. CLEARANCE TO COMBUSTIBLES: FDVS Termination: 0", FOVP Flexible Oil Vent Pipe: 1". These clearances are to maintained unless superceded by the appliance manufacturer's installation instructions or by National and/or local codes (see Step 3). CONNECTING THE VENT PIPE FROM THE FDVS TO THE APPLIANCE 1. Figure 3 ­ Top View The venting system should be installed and supported in accordance with the latest version in the USA of the National Fuel Gas Code ANSI Z223. 1, UL-726, National Fire Protection Association NFPA31, and in Canada CSA B140, CSA B139 Installation Code or in accordance with any other local codes or the authority having jurisdiction. Where requirements for venting differ the most stringent standard requirements shall apply. A vent pipe connector, designed for positive pressure venting, shall be supported for the design and weight of the material employed, to maintain clearances, prevent physical damage and separation of joints. All joints MUST be sealed, for positive vent pressure, to prevent flue gas leakage into the structure. Route the vent pipe from the appliance to the vent termination using the minimum number of bends as possible. The last horizontal section of the vent pipe should have a slight downward slope from the appliance to the vent termination. For clearances to combustible materials and other installation requirements, refer to the National Fuel Gas Code ANSI Z223. 1, UL-726, NFPA31, CSA B140, CSA B139 and/or any applicable local codes or appliance manufacturer's installation instructions. Refer to the appliance manufacturer's specifications for maximum length of vent pipe run. [. . . ] As part of the yearly maintenance schedule, remove the Intake Access Panel on the exterior of the FDVS vent termination (See Figure 2) and remove any debris or foreign material. Be sure to properly replace the panel. Page 3 1. FIELD CONTROLS DIRECT VENT SYSTEMS VENT PIPE ASSEMBLY Figure 4 APPLIANCE ADAPTER INSTALLATION: 1. Remove all oil and grease from the inside of the appliance adapter, and apply a bead of sealant to inside of adapter ½" from end (Figure 5). [. . . ]
