4.Confirming that all unused chimney or "B" vent connections are properly sealed.
5.Verification that the chimney is properly lined and sized per the applicable codes.
Masonry Chimney:
This furnace can be common vented into an existing tile lined masonry chimney provided:
1.The chimney is currently serving at least one drafthood equipped appliance.
2.The vent connectors and chimney are sized in accordance with the applicable sections of the (U.S.) National Fuel Gas Code ANSI Z223.1/NFPA54, and/or CSA B149.1 Natural Gas and Propane Installation Codes.
This furnace must NOT vented ALONE into an existing masonry chimney (either tile lined or unlined) unless the chimney is also lined with either a type B vent system or a listed single wall, metal lining system. Both of these systems must be sized in accordance with the applicable sections of the (U.S.) National Fuel Gas Code ANSI Z223.1/NFPA54, and/or CSA B149.1 Natural Gas and Propane Installation Codes.
Before venting this furnace into a chimney, check the chimney for deterioration and repair if necessary. This furnace must not be vented into a chimney serving a separate appliance designed to burn solid fuel. Type"B" vent connectors must be used on all installations and it must be sized per the applicable sections of the (U.S.) National Fuel Gas Code ANSI Z223.1/NFPA54, and/or CSA B149.1 Natural Gas and Propane Installation Codes.
Type "B" Vent:
The furnace is also approved for use with a "B" vent that terminates through the roof. Refer to the applicable sections of the (U.S.) National Fuel Gas Code ANSI Z223.1/NFPA54, and/or CSA B149.1 Natural Gas and Propane Installation Codes for proper sizing and
Horizontal Venting:

Follow instructions included with venting kit for proper installation and setup.
Location Requirements for Horizontal Venting:
Locate the vent terminal adhering to the following minimum clearances and as specified in the auxiliary draft inducer vent kit:
1.Vent terminal must be located at least one (1') foot above the grade or at least one (1') foot above the normal expected snowfall.
2.Avoid installing vent terminal above public walkways. If this is not possible, install the terminal at least seven (7') feet above the walkway.
3.Vent terminal should be at least four (4') feet to the side of and at least one (1') foot above doors and windows.
4.Vent terminal should be at least three (3') feet above any forced air inlet located within ten (10') feet.
5.Vent terminal should be located at least six (6') feet from the combustion air intake of another appliance.
6.Vent terminal should be located at least four (4') feet above any electric or gas meters, regulators, and relief equipment.
General Venting Requirements:
This furnace may be common vented only with other Category I appliances. Common venting is allowed as permitted by National and/or local codes. Refer to the applicable sections of the (U.S.) National Fuel Gas Code ANSI Z223.1/NFPA54, and/or CSA B149.1 Natural Gas and Propane Installation Codes for proper sizing and set up.
The vent must be terminated with a listed vent cap. This venting must be installed in accordance with the vent manufacturer's instructions and be in accordance with all local codes and/or National Codes. Follow Figure 9 for vent exit options.
The following requirements are provided for a proper venting system:
