MOUNTING INDUCER BASE ON CLAY TILE FLUE LINERS
NOTE: Discard mounting plate, pipe straps and pipe clamps if mounting on a tile flue liner.
1. Flip the Inducer Base bottom side up and position finger clamps in each corner. Place washer on (4) 3 1/2" adjustment bolts and
insert through holes in corners and thread into finger clamp. Insert (4) 1/2” 10-32 carriage bolts through slots in finger clamps
and through Inducer Base holes. Loosely secure on top side of Inducer Base with included (4) 10-32 lock nuts, (See Diagram C).
2. Place a generous bead of RTV or equivalent high temperature silicone on top of tile liner, (See Diagram D). Position the
Inducer Base on top of the chimney liner, inserting the finger clamps into the liner interior. IMPORTANT: Note location of hinges to
make sure that the Inducer Base is positioned so that Inducer swings towards the desired direction. The electrical whip is located
on the hinged side. Once positioned in center of flue, pull the head of each 3 1/2” adjustment bolts out until the finger clamps make
contact with the interior wall of the liner. Tighten opposite corners until finger clamps firmly secure the Inducer Base to the liner inte-
rior. CAUTION: Over-tightening could crack tile liner, (See Diagram E).
3. When finger clamps are firmly tightened, tighten down finger clamp 10-32 lock nuts on top of Inducer Base, (See Diagram F).
4. Place Adapter Plate on Inducer Base and mark Adapter Plate underside with a marker by tracing the interior of chimney,
CAUTION: Sharp edges-wear gloves. If underside cannot be easily marked take measurements of chimney to determine Adapter
Plate opening, (See Diagram G).
5. If Adapter Plate can’t be easily marked by tracing interior of chimney, mark center lines on Adapter Plate and use chimney opening
measurements to mark the Adapter Plate to cut out chimney opening, (See Diagram H).
6. Fill any gaps on exterior of chimney flue and
Inducer Base with RTV or equivalent high
temperature silicone, (See Diagram I).
7. Use a tin snips or equivalent to cut marks made
on Adapter Plate to expose inside of tile liner.
Confirm Adapter Plate opening exposes full
chimney opening. Place a thin bead of RTV or
equivalent high temperature silicone around
Adapter Plate opening and place silicone side
down on Inducer Base, (See Diagram J).

EITHER MARK ADAPTER PLATE FROM UNDER-
SIDE (CAUTION: METAL IS SHARP WEAR
GLOVES) OR TAKE MEASUREMENTS OF CHIM-
NEY TO DETERMINE ADAPTER PLATE OPENING. IF ADAPTER PLATE CAN’T BE EASILY MARKED
BY TRACING INSIDE OF CHIMNEY, MARK CEN-
TER LINES ON ADAPTER PLATE AND USE
MEASUREMENTS FROM STEP 4 TO MARK
LINES FOR ADAPTER PLATE OPENING.

USE A TIN SNIPS OR EQUIVALENT TO CUT
MARKS MADE ON ADAPTER PLATE TO
EXPOSE INSIDE OF TILE LINER. CONFIRM
ADAPTER PLATE FULLY EXPOSES INSIDE OF
CHIMNEY AND ADHERE TO INDUCER BASE
WITH A THIN BEAD OF HIGH TEMP SILICONE.
DIAGRAM I
FILL ANY OPEN AREA BETWEEN EXTERIOR OF
CHIMNEY FLUE AND INDUCER BASE PLATE
WITH RTV OR EQUIVALENT HIGH TEMPERA-
TURE SILICONE.
WHEN FINGER CLAMPS ARE FIRMLY TIGHTENED,
TIGHTEN DOWN FINGER CLAMP LOCK NUTS ON
TOP OF INDUCER BASE.
INSERT 3 1/2" ADJUSTMENT BOLTS & WASHER
THRU HOLES IN CORNERS, THREAD INTO FINGER
CLAMP. INSERT STAINLESS 10-32 CARRIAGE BOLTS
THROUGH SLOTS IN FINGER CLAMPS INDUCER
BASE HOLES. LOOSELY SECURE ON TOP SIDE OF
INDUCER BASE WITH INCLUDED 10-32 LOCK NUTS.
PLACE A GENEROUS BEAD OF RTV OR
EQUIVALENT HIGH TEMPERATURE SILICONE
ON TOP OF CHIMNEY TILE LINER. TIGHTEN OPPOSITE CORNERS UNTIL FINGER
CLAMPS SNUGLY SECURE THE INDUCER BASE
TO THE LINER INTERIOR. CAUTION: OVER-
TIGHTENING COULD CRACK TILE LINER.
