MODEL VH1 SERIES VENT HOODS 6”, 8”, 10”
The VH1-8 and VH1-10 do not have a secondary heat shield. A thimble will have to be added to maintain clearances to
combustibles if penetrating a combustible wall with these models.
1.
Terminate the vent system so that proper minimum clearances are maintained as cited in the latest edition of the
National Fuel Gas Code (NFPA # 54) and the latest edition of NFPA #211, or as follows:
• Not be less than 7 feet above grade when located adjacent to public walk ways
• At least 3 feet above any forced air inlet located within 10 feet
• At least 4 feet below, 4 feet horizontally from or 1 foot above any door, window or gravity air inlet into any building
• At least 12 inches above grade.
THE MANUFACTURER ALSO RECOMMMENDS:
• The vent terminal shall also not be installed closer than 3 feet from the inside corner of an L-shaped structure
• Not less than 2 feet from an adjacent building
• Flue gases are not directed so as to jeopardize people, overheat combustible structures or enter buildings
2.
Check vent pipe system for leakage. All vent pipe joints on “positive” side of power venter must be sealed.
3.
A vent system incorporating a Tjernlund VH1 Series vent hood should not exceed 550
o
F. gross.
4.
Termination of a sidewall vent system with a device other than the Tjernlund VH1 vent hood could affect system
performance and result in a possible safety hazard.
5.
Plan the vent system layout to avoid the possibility of accidental contact with concealed wiring or plumbing inside walls.
6.
Installation must be done by one experienced and familiar with venting of combustion gases.
