TJERNLUND DRAFT INDUCER DJ-3 Bedienungsanleitung
Improve Heating Efficiency
In-Line Draft Inducers assure positive draft
when restricted boilers and furnaces, poor
chimneys or negative pressures in build-
ings prevent proper exhaust of combus-
tion gases. The Venturi action starts air
moving up the stack instantly and keeps it
moving smoothly. In-Line inducers are
built for long-lasting, trouble-free service
and available in sizes and capacities to
meet virtually all heating system require-
ments. The Vari-Draft control permits
adjustment to individual job require-
ments. Vents/Chimneys utilizing In-Line
Draft Inducers must be vertically terminat-
ed above the roof line.

■Select a position between draft
hood, diverter or barometric
damper and chimney, locating
the Inducer as close to the
chimney as possible. Inducer
should be mounted 2-3 pipe
diameters away from a directional
change, i.e. elbows and tees, so turbulence is not created.
■Mount the Draft Inducer on vertical, horizontal or inclined vent
pipe. If used on a horizontal vent pipe, mount Inducer on bottom
of pipe, not on top, to avoid creating a heat trap in the Inducer.
■The motor shaft must be level and horizontal to avoid excessive
wear on bearing.

* Models DJ-3 & D-3 fasten with screws.
■If change in vent pipe size is required, use a tapered
increaser or reducer.
■In-Line Inducers should be installed on a section of single
wall vent pipe in order to assure proper performance.
■Do not use In-Line Draft Inducers on condensing heating
equipment.
■We recommend the use of a carbon monoxide detector
in all mechanical rooms.
Fan Prover Safety Interlock
Model PS1505
To satisfy national mechanical codes for oil and gas installations,
Draft Inducers must be properly interlocked with burner circuits.
The PS1505 Fan Proving Switch monitors pressure within the
Inducer housing to verify Inducer operation. Used in conjunction
with the UC1 Universal Control, it assures compliance with codes
and simplifies electrical interlock with all 24 /115 VAC burner
circuits. The PS1505 is not compatible with millivolt gas valves.
with National Mechanical Codes
Chimney
Quality engineered and
manufactured to maintain a
consistent draft on a wide
range of oil and gas fired
heating equipment. May be
used with chimney vented or
power vented heating equip-
ment. For fan assisted gas, oil
or solid fuel applications with
vent diameters from 4"–10",
choose the DC4 thru DC10.
For LP and natural gas appli-
cations with vent diameters from 4"–10", choose the DC4G
thru DC10G.
Used with any UC1 con-
trolled Inducer to inter-
lock additional 24/115
VAC heaters. Powered by
and communicates with
the UC1 through a factory
wired whip. For one
additional 24/115 VAC
heater add the MAC1E.
To interlock up to four
more additional 24/115
VAC heaters, add the
MAC4E. MAC4Es can be
daisy chained together for greater than 5 heaters. Important:
Total combined BTU/hr. input of all heaters and total equivalent
pipe lengths must be within Inducer’s capacity.
For use with UC1 Universal
Control, MAC1E or MAC4E
auxiliary controls. The WHKE
gas pressure switch actuates
the Inducer through the A - B
dry contacts. The Linear Limit
switch disables the heater in
the event of a venting
malfunction. Includes JA1
thermocouple junction
adapter. To interlock millivolt
water heater(s) only with a
UC1 controlled Inducer add a
WHKE for each millivolt heater. To interlock a millivolt water
heater and one 24/115 VAC furnace or boiler with a UC1
controlled Inducer, add a WHKE and a MAC1E.
Solid state control interlocks
with virtually any burner control
circuit. Features include:
adjustable pre and post purge,
LED status/diagnostic indicators,
prover switch delay to avoid
burner start up and wind
induced short cycling. Interlocks
with any 24/115 VAC burner
control circuit and also includes
“dry”contact actuation option.
Selectable voltage eliminates
false activation by burner control
check circuits.

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.

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.
