Venting
Install a barometric control device in the vent
connector as shown in Fig. 13 and 13A and
adjust per the manufacturer’s instruction when
excess draft needs to be relieved or when
applicable codes require a device.
Install an induced draft fan in the chimney for
applications in which:
- Excessive resistance to the flow of flue
gases is excepted
- The cross-sectional area of the chimney
is smaller than the minimal area
required
- The chimney height is less than the
minimal requirement
When using an induced draft fan the installer
should seal all vent joints and provide an inter-
lock system for the ELITE to ensure fan oper-
ation.
Oil Vent - Direct Vent Applications
The installer must read and comply with the
direct vent instruction outline in Triangle Tube
Oil-Fired Direct Vent Instructions.
The installer should give attention to the loca-
tion of the ELITE prior to installation. The
installer should:
- Locate the unit for shortest possible
vent length and the most direct path to
the outside wall.
- Note that flue gases will form a white
plume in colder climates which may
obstruct window views
- Note that prevailing winds could cause
nuisance lockouts, freezing of conden-
sate and water/ice build-up may occur
on buildings, plants and roofs.
The installer should consider the following
when determining the location of the vent ter-
mination:
- Locate or guard the vent termination in
a manner to prevent accidental contact
by people or pets.
- Vent must terminate at least 4 feet
below and 4 feet horizontally or 1 foot
above any window, door or gravity air
inlet to the building.
- Vent must terminate not less than 7 feet
above grade when located adjacent to a
public sidewalk.
- Terminate the vent at least 6 feet from
adjacent walls
- The bottom of the vent termination
shall be located at least 1 foot above the
grade, including normal snowline.
- DO NOT terminate the vent into win-
dow wells, stairwells, alcoves, court-
yards or other recess area.
- DO NOT terminate vent above any
window, door or gravity inlet as con-
densate can freeze causing ice forma-
tions.
