1. Inputs shown are
believed to be maximum
capacities for inducers
when mounted on pipe
sizes shown for ordinary
jobs where a moderate
amount of mechanical
induced draft is required.
2. Consideration is given
to typically higher static
pressure requirements for
larger installations, for the
type of fuel burned and
for the type of draft
control installed.
3. Some ratings may only
be valid for extremely
short vent lengths due to
excessive pressure loss; i.e.
the Model IL gas firing
with draft hood in 10"
pipe at 2,080,000 BTU/hr.
4. Where pressure require-
ments are unknown or
believed to be unusually
severe, ask for complete
performance curves or
consult factory.
5. Draft Inducers should
be installed in single wall
vent pipe in order to assure
proper performance.

Electrical Specifications
IMPORTANT: Vents/Chimneys utilizing In-Line Draft Inducers must be vertically terminated above the roof line.
Do not use for side wall venting. Consult factory for proper side wall vent system options.
Tjernlund Products also offers:
Auto-Draft variable & fixed speed Inducers for roof top or side wall
venting. Reduce vent diameters by up to 50% and overcome convolut-
ed vent layouts. Fan speed is automatically regulated based on a user
set manifold/vent pressure, resulting in perfect draft and true energy
savings. Virtually unlimited capacities.
Combustion Air In-Forcers provide dedicated combustion air for safer,
more efficient equipment operation. Eliminates burner control lockouts
& oil odors associated with backdrafting. Ideal for "confined space" and
electric to oil or gas conversions. Residential and commercial fixed &
variable speed capacities up to 6000 CFM available.
