All single wall chimneys must be at least 18” from any combustible surface. Fire can
result, causing severe personal injury, death, or substantial property damage.
A major cause of chimney-related fi res is failure to maintain required clearances
(air spaces) to combustible materials. It is of the utmost importance that all chimneys be
installed in accordance with the manufacturer’s instructions.
CHIMNEY MATERIAL
The Boiler must be connected to either a:
1) Class “A” masonry chimney
2) All Fuel metal insulated chimney (8”)
3) Listed type “HT” double wall chimney approved for temperatures up to 1400 °F (8”)
CHIMNEY CONNECTORS
Connectors will be required to attach appliance to chimney unless chimney is attached direct.
1) Chimney connector can either be:
A) 6” or 8” galvanized, black or blue steel, stove pipe with adapter only at the “T”
• Maintain 18” clearance to combustibles.
• Minimum thickness: .028 inches (24 gauge minimum)
B) 6” or 8” listed type “HT” double wall chimneys.
• Maintain 2” clearance to combustibles.
2)
Boiler must be the only heating appliance connected to a single chimney fl ue.
3)
Keep the connector as straight and short as possible.
A) Minimize elbows.
B) Maximum horizontal distance between boiler and chimney: 6 Ft.
C) “Male” end should point back to boiler.
D) Horizontal runs must be pitched back to the boiler in accordance with local Building Codes
(typically 1/4” pitch per Foot of horizontal run minimum).
E) Secure each connection with a minimum of 3 screws.
4)
Assemble in accordance with the vent manufacturers instructions. Additional sections may be required to
clear the peak of the structure. Do not install more than one appliance per fl ue.
5)
When burning coal, a barometric draft damper MUST be installed between the boiler and the chimney to en
sure adequate draft.
DO NOT install more than one appliance per fl ue. Flue gas spillage and carbon
monoxide emissions can occur causing severe personal injury or death.
CHIMNEY MUST BE INSTALLED OR INSPECTED BY A PROFESSIONAL AND
MEET ALL LOCAL AND STATE REQUIREMENTS AND CODES FOR WOOD OR
COAL BURNING APPLIANCES OPERATING CONDITIONS.
