Inspection 4. Woodburning Appliance Installation Issues
Woodburning UL 1482 Prohibitions • Garages • Areas where flammable liquid vapors may be present • Enclosed spaces less than 512 cubic feet – 8’x 8’ – unless listed for alcoves
Woodburning Connector Pipe • Avoid elbows –Use 150 elbows instead of 300 • Avoid horizontal runs – Minimum ¼“/foot rise for horizontal runs
Woodburning Connector Pipe
Woodburning Connector Pipe • Materials – NFPA 211 prohibits use of galvanized steel – NFPA 211 requires 24 gauge or more • Size and length – At least appliance flue collar size – Long runs can affect draft adversely and increase creosote buildup
Woodburning Connector Pipe Replacing an existing woodstove? • • Heat expectations Flue size Flue configuration Start up techniques
Woodburning Venting
Woodburning Venting • • Never use an unlined chimney. Two solid fuel appliances cannot share a common flue. Maximum size 3 x larger than the appliance flue. • • 2 x if chimney is on an outside wall or in Canada.
Woodburning Masonry Chimneys
Woodburning Masonry Chimneys • Condition of flue liner – Cracks, soft, mortar joints in place and tight – Free of creosote • Connection of other products – Cannot share flue with solid fuel product – Can be in same chimney on separate flue • NFPA 211 requires a cleanout
Woodburning Venting Height • 3 feet above the highest point penetration • AND at least 2 feet above anything within 10 horizontal feet
Woodburning Venting Height
Woodburning Factory-Built Chimney • • Double wall or triple wall Air insulated, solid insulation, combination UL 103 HT required for woodstoves Single wall chimney connector not a chimney and should not penetrate combustibles
Woodburning Firestop Spacers • Blocking to prevent fire spread • Correct spacing to meet clearances • Provides lateral (side to side) support
Woodburning Firestop Spacers With room above: installed below joist Unoccupied attic above: installed above joist
Woodburning Location
Woodburning Location
Woodburning Fireplace Insert • Fireplace and chimney in good working order • Some require hearth extension protection • Alterations: variations by manufacturer – Required removal of damper and grate – Refractory, smoke shelf, baffles, screen, doors can be removed – Insulation can NOT be removed
Woodburning Fireplace Insert • Surround Installations – Gap between fireplace face and panel may be required for air circulation and cooling – Insulation along top of insert may be required for mantel clearances – May allow installation without panel if minimum gap with mesh maintained – Air inlet grilles on factory-built fireplaces important consideration
Woodburning Fireplace Insert • Factory-Built Fireplaces – Most fireplace manufacturer’s only allow inserts specifically listed for use with specific model – NFPA 211 requires Type HT chimney and insert listed for use with specific fireplace – Warranty may be voided if insert not approved 12
Woodburning Fireplace Insert • Direct Connect – Stainless connector to first flue liner – Minimum NFPA 211 requirement for installation of insert in masonry fireplace – No dilution air
Woodburning Fireplace Insert • Re-line to top – Easier startup – Better performance – Less frequent, expensive, difficult maintenance
Woodburning Chimney Liners
Woodburning New Technology For Combustion Air • Air enters through attic support box, roof flashing, or wall thimble • Ducted from connector to appliance air inlet
Woodburning Installation “Characteristics of a Perfect Woodstove Installation” Wood ‘n Energy Magazine 1985
Perfect Installation Balanced ventilation system in the home Outside air to firebox: • Open fireplaces require 200 -300 cfm • EPA woodstoves require 11 -32 cfm • 4”outside air brings in about 10 cfm
Perfect Installation Chimney is inside the building envelope • Keep flue gases warm for optimum draft • Prevent cold hearth syndrome in standby and startup
Perfect Installation Chimney is insulated to prevent heat loss
Perfect Installation Chimney is correct size • No smaller than flue collar area • Maximum Size • No larger than 3 times flue collar area if inside the building envelope. (2 x in Canada) • No larger than 2 times flue collar area if one or more walls are exposed to the outside. • Same as flue collar area best
Perfect Installation Penetrates the highest part of the house House Stack Effect Leaks, open windows in upper portion create greater chimney effect than vent
Perfect Installation Chimney is tall enough • 3 feet above the highest point of roof penetration • 2 feet above anything within 10 horizontal feet
Perfect Installation Chimney is tall enough • EPA woodstoves may need minimum 15' total venting system (connector + chimney) • High altitude • Manufacturer may recommend heights to be increased 2 -3% per 1000 feet of elevation • Extremely tall chimney can cause over drafting • Damage to combustor and/or internal parts • Shorter appliance life
Perfect Installation Chimney is clear of obstacles
Perfect Installation Connector pipe runs straight up • Avoid elbows • Use 15º instead of 30º • Avoid horizontal runs • Minimum ¼“/foot rise
Perfect Installation Home owner is informed • Normal operation • How to light a fire • Maintenance • Ash removal • Chimney Maintenance • Catalytic Combustor care • Break-in fires
Perfect Installation Home owner is informed • “Burn Wise” video http: //www. hpba. org/consumers/hearth/responsible-wood-burning • “The Heating with Wood DVD Set” http: //www. woodhomeheating. com
Characteristics of a “Perfect” Installation 1. 2. 3. 4. 5. 6. 7. The house has a balanced ventilation system. Chimney runs inside the building envelope. Chimney is insulated and the correct size. Chimney penetrates the highest part of the house. Chimney is tall enough and is clear of obstacles. Connector pipe runs straight up. Homeowner is informed regarding properation.

Potential Problem Areas
Blowers and Grates • Blowers – Only listed for use with fireplace – Follow instructions for blower and wiring – No connection to cold air furnace returns • Grates – Some manufacturers prohibit use of grates – Replacement only with manufacturer specified grate – If no specifications, 2/3 hearth area or less – No alterations or raising/lowering of grates
Catalytic Combustor • Available for some fireplaces – Original equipment or retrofit for some factory-built appliances – Retrofit for masonry fireplaces • May carry EPA hang tag – Catalyst must be replaced every 3 -5 years for proper performance 12
Glass Doors • Doors standard on some fireplaces, optional on others, not allowed on some – Required for fireplaces listed for installation in mobile homes • ONLY doors listed and specified by the manufacturer for use with factory-built fireplaces – Unauthorized doors can lead to damage and fire hazards • Air grilles should not be covered
Installer Qualifications • NFGC calls for “qualified agency” • Manufacturers’ instructions – Qualified technicians – Some suggest or recommend industry certification • Jurisdictions – Some have no requirements – Some have qualifications based on broad categories of heating equipment – Growing number considering specialty licenses specifically for gas hearth products installers
Installer Qualifications • National Fireplace Institute (NFI) – Focused solely on hearth products – Certification exams meet national standards for reliability, validity, legal defensibility • www. nficertified. org
Maintenance Qualifications • Chimney Safety Institute of America (CSIA) – Inspection and cleaning or repair of chimneys and vents – Certification exams • www. csia. org
