WARNING
!
Insufficient flueing and/or improperly sealed flues may release gas into the building
which could result in health problems, carbon monoxide poisoning, or death.
Improper flueing may result in fire, explosion, injury, or death.
Seal flue pipes with high temperature sealant and three (3) sheet metal screws. Flue
enclosed spaces and buildings according to the guidelines in this manual and applicable
national, state, provincial, and local codes.
The heating system may operate either flued or unflued (see page 28). Flueing can terminate through the
sidewall (horizontal) or the roof (vertical), and be individually or commonly flued.
Follow these guidelines and all applicable codes for all models prior to installing the flue material. Local codes
may vary. Refer to current I.E.E. Regulations and other relevant codes of practice.
Flueing Requirements
• Seal single wall flue with high temperature sealant and three (3) sheet metal screws.
• Single wall galvanized flue pipe must be insulated in cold environments.
• Do not use more than two 90° elbows in the exhaust flue.
• To maintain clearances to combustibles, the use of an approved wall or roof thimble and double-wall type
B-vent is required for the portion of flue pipe that runs through combustible material in the building wall or
roof (see Figures 3.20 & 3.21).
• The maximum flue length is 6,1 m.
