- 7 - 23. Soldered Gas Lines: Illegal and not acceptable. Must be corrected to code. Flex Line: The commonly-found pleated copper lines or flex-lines are not approved. They must be replaced using solid iron pipe or soft- copper tubing with flared fittings. At the present time no flexible connectors of any kind have been approved by the State of Minnesota for residential use. Condition of Gas Valves: These are emergency shut-off devices for any gas appliances such as the gas range, spaceheater and dryer. They must be easily operated without the use of a tool . Sticking valves cannot be accepted nor can they be loosened if they have a hex nut (because this will cause leakage) . If new valves are required, they must be UL or AGA-approved or ball valves. All must be in an easily accessible location. No valve can control more than one appliance and all gas appliances must have an operable shut off valve. 24. Flues: Must be in good condition. Excessive corrosion or weakness is not acceptable. All joints must be secured with metal screws. Flues (Class "A") for Woodstoves and Solid-fuel Appliances: These need to be installed as part of an overall accepted heating system package. They must be approved and listed and must be installed as per manufacturer's specifications. Unlisted items must be removed or modified to meet proper clearances to combustibles. Diverters: Where required and existing on a flue, they must be in good .operating condition (no deterioration) . Clearances: Clearances to combustibles or insulation must be met in all types of flues. A class "C" flue (single metal wall) requires a minimum of 6 inches to combustibles (e.g. wood framing and/or paneling in a basement partition wall) . A class "B" flue (double wall ) requires a minimum of 1 inch to combustibles. NOTE: If the requirements for class "C" cannot be met without major remodeling, sometimes the replacement of the "C" flue with a "B" flue (needing 1 inch clearance) will solve the problem. An approved chaseway must be supplied for all flues. where they go through any living or storage area (e.g. main floor closet) to maintain a proper clearance to combustibles. 25. Masonry Chimney Condition: Must be in satisfactory condition. All holes need to be permanently sealed with concrete. If appliance flues enter chimney, they must be mortared in. Where there is a metal lining in a chimney, a drip-T moisture-escape tube must be at bottom. Fireplaces: Must be in good condition. All gaps and loose bricks must be mortared with fire-resistive mortar. Dampers must be operable. The condition and installation of the firebox can be of a surface visual inspection only and cannot guarantee that it was correctly installed initially. No fireplace can be installed unless directly integral with chimney (no intervening flue) and cannot share liner with any appliance. Combustible material shall not be placed within 6 inches of the fireplace opening.
