ENCORE 2550 HARDWARE

HISTORY OF CHANGES
1995 DEFIANT ENCORE
Model 2550
This section covers the Defiant Encore Model 2550, built beginning in March, 1995.
In March 1995, Vermont Castings changed the Defiant Encore stove to simplify
assembly and minimize enamel chipping.
•The visible parts of the front doors are now one casting instead of two. This
ensures a good enamel colour match and minimizes chipping during
assembly.
•The front door latch is lower than on earlier models, and catches on a steel
fitting bolted to the stove front. This keeps the latch from chipping the
enamel lip above the doors.
•The damper handle is relocated toward the back edge of the left stove side.
Damper operation is reversed from the previous design; you pull the handle
toward the front of the stove (counter-clockwise) to close the damper. The
damper now has an adjusting screw, visible through the firebox and no
linkage as it is a direct straight through design.
In March 1997, in order to avoid confusion with stove names, Vermont Castings changed
the Defiant Encore stove name to Encore as the new Defiant 1910 was just introduced.

SERVICE PROCEDURES
1995 DEFIANT ENCORE
Model 2550
This section covers repairs and adjustments to the model 2550 Defiant Encore stoves
built since March, 1995. Service procedures for this model are identical to those for the
previous model 2190 Defiant Encore, except in three areas: damper adjustment; the
removal, re-gasketing, and replacement of the upper fireback / damper assembly, and
adjustments to the front door.
**Wear gloves, a dust mask and protective eyewear when servicing a stove. **
Replacing the Refractory Package
1. Open the damper and remove the handle stub (“faucet”).
2. Remove the andirons; one 7/16” hex head bolt each.
3. Remove the throat hood; swing its bottom edge forward and then slide hood to one
side until the trailing end drops from its support. Take it out of the stove.
4. Remove the two wedges that hold the lower fireback in place.
5. Remove the lower fireback. Simply lift it out of the firebox.
6. Remove the left and right wear plates; two 7/16” hex head bolts each
7. Remove the upper fireback. Two hex head bolts hold it in place. The heads are on
the outside of the stove back. Swing the right end of the upper fireback assembly
forward and let it drop into the fireback.
8. Carefully pull the entire refractory package straight forward. Leave the steel heat
exchangers in place in the left and right sides of the stove back.
9. Install the new refractory package. Replace the catalyst. Install the access panel.
10. Inspect, clean; or replace the fireback as needed.
11. Re-install the upper fireback assembly; fasten it in place with two ¼”-20 x 1-½” hex
bolts.
12. Attach the handle and its ‘faucet’ to the handle rod with the Allen bolt, and test the
damper for smooth action.
13. Re-install the left and right wear plates, with their two bolts each.

14. Re-install the lower fireback, and secure it with two wedges.
15. Replace the throat hood.
16. Re-install the andirons.
Replacing the Primary Air Cable
1. Remove the throat hood.
2. Remove the right wedge, between the right wear plate and the lower fireback.
3. Remove the right wear plate (bolts at top and bottom, 7/16” heads).
4. Remove the thermostat handle from the thermostat stem with an Allen wrench.
5. Pull the thermostat and stem assembly into the firebox. Be sure to hang onto the
friction spring on the stem.
6. Remove the primary air frame and valve assembly. Pull the frame away from the
stove bottom and to the right gently, to protect the primary air rod.
7. Detach the old cable from both ends. Be sure to keep the small clip that joins the
upper end of the cable to the thermostat.
8. Fish the new cable through the primary air opening at the bottom of the right side of
the firebox and through the primary air frame opening at the back bottom of the stove.
9. Attach both ends of the cable. Be sure the cable hangs properly from the rod on the
thermostat stem, and passes under the stem. Be sure the friction spring is on the
thermostat stem; push the stem through its hole in the stove side and re-attach the
handle with the Allen bolt. Swing the handle back and forth to ensure that there’s a
bit of tension on the friction spring. If there’s not enough tension on the spring to
hold the thermostat assembly in place when you release it, loosen the Allen bolt on
the handle stem and push the stem further out through the stove side, and re-attach the
handle.
10. Clean the primary air frame and its mating surface of any old stove cement. Bolt the
frame back into position, and test the thermostat action to be sure the valve nearly
closes when the handle is swung fully to the rear.
11. Replace the right wear plate, with the two hex bolts, and replace the wedge that held
the lower fireback in place.
12. Replace throat hood.

Adjusting the Damper
To adjust the damper to compensate for compression of the gasket, start by removing the
griddle. Then:
1. Loosen the lock nut in the centre of the damper.
2. Use and Allen wrench to turn the pressure screw about one-half turn clockwise.
3. Test the damper’s closing action. Do not over-tighten the screw, as this can cause
binding when the parts expand under heat.
4. When the damper closes smoothly and snugly, tighten the lock nut and replace the
griddle. (Fig. 1)
Fig. 1 Damper lock nut Fig.2 Damper components
Adjusting the Positions on the Front Doors
The doors are factory-set to ensure a good seal between them and the stove front. If
necessary you can adjust their position slightly by loosening the bolts that hold them to
the hinge strips on their edges. Loosen the bolts only enough to enable you to nudge
them up or down; do this with the doors fully open to avoid hitting them against the front
of the stove. Re-position the doors as necessary (being sure that the latch engages its
catch properly) and then tighten the bolts. Check the fit with a slip of paper, and adjust
the latch as needed.

DISASSEMBLY and ASSEMBLY
1995 DEFIANT ENCORE
Model 2550
Disassembly
1. Lift off the griddle and the front doors. Remove the ash pan and dump the ashes.
The pan will be a convenient place to store hardware during disassembly.
2. Lift out the grate and loosen the bolts holding the andirons in place. Lift out the
andirons.
3. Loosen the Allen bolts holding the thermostat and damper handles in place, and
remove the handles.
4. Remove the throat hood by pulling its bottom edge forward till it clears the ribs on the
lower fireback; then slide it to either side. It will the fall into the firebox. Tap out the
wedges holding the lower fireback in place. Let the fireback fall forward and lift it
out.
5. Remove the two hex-head bolts holding the left and right inner walls (‘wear plates’)
in place, and remove the wear plates. You may need to pry the forward edges of the
plates to get them out of position. Be sure to pad the edges of the enameled stove
front if you use a prying tool.
6. Remove the upper fireback assembly. It is held in place with two bolts going inward
from the outer stove back. When the bolts are out, pry the right end of the assembly
forward, and remove the assembly through the firebox.
7. Remove the flue collar. It is held by bolts and square nuts.
8. Remove the left and right stainless-steel heat deflectors from the back of the stove.
Carefully slide the refractory chamber, including the combustor, forward into the
firebox, and lift it out. Handle it carefully, as it’s fragile.
9. Disconnect the thermostat cable from the thermostat rod, and remove the thermostat
assembly by pulling it into the firebox. Be sure to keep the small coil spring that is
on the main stem.
10. Remove the stove top. There are nuts on two vertical threaded stems at the left and
right rear corners of the firebox, and one counter-sunk Phillips bolt in front, under the
griddle handle notch. Since the top traps the stove back in place, either have a helper
hold the back up while you remove the top, or put a rope or strap around the stove
body before you remove the top. Then remove the back.

11. Remove the one side, then the other. They each have one bolt joining them to the
stove front, and one bolt joining them to the bottom. When the hardware is out, break
the cement seals and lift the parts off.
12. Remove the stove front. It has one bolt going through the middle of its bottom and
into the stove bottom. The air manifold will come with the front when you remove it.
13. Remove the air tube cover. It has one bolt at each side, going downward into the
stove bottom.
14. Flip the bottom assembly over, and remove the legs. The left front leg bolt head
captures the ashdoor will then come off.
15. Remove the ashlip. It has two bolts going upward into the stove bottom.
16. Remove the ashdrop. It has four hex-head bolts joining it to the stove bottom.
17. Remove the air manifold from the stove front. It has one hex-head bolt at the top.
18. Examine all castings for cracks, chips, or distortions. Repair or replace as needed.
Repair all old gasket material. Use a cold chisel or an old screwdriver to remove old
stove cement from cement channels and mating surfaces.
19. Remove the damper from the upper fireback, and remove the gasket. Examine the
damper tabs and replace as needed.
ASSEMBLY

Instructions and illustrations are given at the end of this section of the manual.
Cementing
Prepare parts which will need to be cemented before starting to assemble the stove, but
do not apply cement until just before installing the parts.
Cementing instructions are given below. Illustrations showing where to apply cement are
given as needed in the assembly instructions.
Prepare parts carefully so that new cement makes a tight seal between the parts to be
joined. The channels and edges to be cemented must be free of old cement and dust.
Use high quality stove cement.
New cement hardens quickly when exposed to air.
•Clean and prepare parts ahead of time.
•Apply cement just before putting the parts in place.
**Work in an area where there is plenty of light, and a level work surface. Wear gloves
and protective eyewear.**
If the parts to be cemented are new, start with step 2. If old parts are to be re-cemented,
they will need to be cleaned. Start with step 1.
1. Clean old cement from the channels and edges to be joined. Use a hammer and cold
chisel, or screwdriver to remove old cement. Use a wire brush to finish cleaning the
channels and edges. Vacuum the channels to remove dust.
2. Wipe the surfaces to be cemented with a damp cloth. Apply a generous bead of
cement in the channel. Excess cement may squeeze out of the joint.
Excess cement which shows on the outside of the unit may be removed with a damp
sponge. Clean up the excess promptly.
Excess cement on the inside of the unit will not usually be a problem. If clean-up is
necessary, instructions will be given.
3. Join the two parts. Move the parts as little as possible after they have been put
together.

Assembly
You will need at least 6 tubes of stove cement to re-assemble a Defiant Encore. Cut the
tips of the tubes so you can apply an unbroken bead of cement to the cement channels
and mating surfaces.
1. Place the stove bottom upside-down. Put a generous bead of cement around the top
edge of the ashdrop (Fig. 3). Attach the ashdrop to the bottom with four hex bolts.
Fig. 3 Ash Drop
Thread a leg leveler into each leg, and install the legs. Put the handle holder on the
right front leg. Use an Allen bolt to secure the left front leg, to accept the ashdoor
hinge.
2. Attach the ashdoor bottom hinge to the bottom of the ashdrop. Attach the ashlip to
the bottom with two countersunk bolts. Attach the ashdoor by running its hinge pin
through the left end of the ashdoor and into the socket head of the left front leg’s
Allen bolt. Run the cotter pin through the hinge pin to hold it in place.
3. Assemble the primary air valve assembly. Put the air frame facedown with the drilled
bosses up. Thread the primary air rod through the hole in the bottom of the air valve
and just start it into the left top (hinge) hole of the frame. Put the valve and rod in the
frame so that the air rod holes
align. Push the air rod from
left to right through the aligned
holes and secure the rod in the
frame with a 1/8” friction clip
(Fig. 4). Turn the assembly
over and install the socket head
cap (adjusting) screw, ¼-20 x
3/18”, in the centre of the air
valve, finger tight.
4. Install the primary air valve assembly on the stove bottom with the hinged side down
(Fig. 5). Secure the assembly with two Phillips round head bolts, ¼-20 x 5/8”.
Fig. 5 Primary air valve attachment

5. Turn the stove bottom over onto its legs. Thread the running end of the thermostat
cable down through the small hole and up through the large hole in the air rod.
Pull the running end of the cable over to the valve and thread it through the small hole
in the centre of the valve. Pull 6” of cable outside the valve. Tighten the set screw
finger tight (Fig. 4 and 5). Pass the thermostat cable through the right-hand gap
between the air cover and the stove bottom. Bolt the primary air cover to the stove
bottom.
6. Cement all the channels, flanges and
mating surfaces indicated in Fig. 6.
Keep the cement off the thermostat
cable.
7. Put the stove front in its cemented
channel on the stove bottom and
secure with one ¼-20 x 1” hex bolt.
8. Install threaded stems in the tapped holes in the left and right back edges of the stove
front. Cement all mating surfaces on the stove front as shown in Fig. 7. Put the air
manifold in position on the inside of the stove front and secure with one hex bolt, ¼-
20 x 2” long.
Fig. 7 Front Fig. 8 Left End Fig. 9 Right End
9. Cement the channels and mating surfaces on the left stove end as shown in Fig. 8.
Put the left stove end into its mating channels in the stove front, swing the back of the
end onto the stove bottom so that the hole in the inside bottom flange of the end
aligns with the tapped hole in the stove bottom. Secure the end to the bottom with a
¼-20 x ¾” hex bolt and a washer.
10. Cement the mating surfaces as shown in Fig. 9. Put the right stove end into its
mating channel on the stove front, swing the back of the end onto the stove bottom so
that the hole in the inside bottom flange of the end aligns with the tapped hole in the
stove bottom. Secure the end to the bottom with a ¼-20 x ¾” hex bolt and a washer.

11. Mount the front to the stove bottom and to the stove ends. The threaded stems on the
back edges of the stove front pass through clevises on the front edges of the stove
ends, and are secured with hex nuts and washers. The front attaches to the stove
bottom with a ¼-20 hex bolt and washer.
12. Put a 1-½” threaded stems into the two holes at the rear corners of the underside of
the stove top. Apply stove cement to the grooves around the underside of the stove
top, and to the rear edges of the stove sides (Fig. 10).
Fig. 10 Top (underside)
Fig. 11 Back (inside view)
13. Apply cement to the grooves in the back – Fig. 11. Put the stove back into position.
It will be easiest to have a helper hold it in place temporarily. Install the stove top,
which captures the top edge of the back, and secure it with washers and hex nuts on
the two threaded stems at the rear corners. Secure the front of the stove top to the
stove front with one Phillips-head bolt, ¼-20 x 1”, passing downward through the
notch where the griddle handle fits.
14. Install the refractory chamber. It should fit snugly against the outer back of the stove,
and downward against ribs on the bottom of the back panel. Install the left and right
heat deflectors in the heat-exchange passages to the left and right of the refractory
chamber.
15. Assemble the upper fireback assembly. This will include the damper, the torsion bar,
and the upper fireback, along with damper tabs.
16. Install the upper fireback assembly. Put the left end into position first, then lift the
right end and swing it out to meet the back of the stove. Secure it with washers and
two ¼-20 x 1-½” hex bolts going in from the outside.
17. Attach the damper ‘faucet’ to the damper rod and tighten the set screw.
18. Install the Left Inner Side; it secures with two ¼-20 bolts. Re-test the damper system
for smooth operation.

19. Install the thermostat. Be sure that the friction spring is on the stem, between the
outer end and ‘ears’ pressed onto the stem, and that the wire stem coming off the bi-
metal coil passes over the stem and toward the front of the stove. Loosely attach the
thermostat handle to the stem, on the outside of the stove. Attach the thermostat
cable to the end of the wire stem, and check the system for smooth operation. The
primary air valve should close to within ¼” of the valve frame with the thermostat
cable swung fully to the rear. Be sure that the friction spring provides enough friction
to keep the valve open when the handle is positioned fully forward.
20. When the thermostat is working well, install the right inner side. It secures with two
¼-20 hex bolts and washers.
21. Put the catalytic combustor into the refractory package, ensuring that it is fully to the
rear. Install the refractory access cover.
22. Install the lower fireback. Ribs on its back side channel secondary air to the
combustor. Be sure the panel is fully down in its bottom channel. Secure it with a
wedge on each end. Install the throat hood; put one of its end pins on a support on the
lower edge of the upper fireback, and slide the hood toward that side until the other
end pin is within the other support, then slide it back until it is centered on the lower
fireback. Let the lower edge of the hood rest against the lower fireback.
23. Install the slotted grate. It simply rests in place, with the wider side of the slots
downward, toward the ashdrop. Bolt the andirons into place.
24. Install the secondary probe
assembly see Fig. 12 for
positioning guidance.
If necessary, loosen the lock
nuts on the probe shaft and
adjust the position of the tab
on the thermostat coil so that
it is at 4 ‘o’ clock as you face
it from the rear, with the
mounting tab at 12 ‘o’ clock.
Insert the double-bent end of the thermostat air link through the hole in the tab end of
the thermostat coil. Insert the single-bent end through the hole in the tab on the
secondary air flap. Insert the probe through the hole in the stove back and secure it
with a Phillips pan-head bolt, #10 – 24 x ¼”. Secure the secondary air flap to the
stove back with a similar bolt and a shim ring. Tighten the bolt holding the air flap
until it is snug, then back it off ¼ turn. Insure that the flap moves freely up and down
and that the flap rests at or near the closed position.
25. Install the secondary air cover plate. Secure it with two Phillips pan-head bolts, ¼-20
x 3/8”.
Fig. 12 Secondary air probe installation

26. Assemble and install the ashdoor. Screw the socket, button head bolt into the stepped
side of the latch pawl (Fig. 13). Thread the hex nut onto the end of the bolt and
tighten it finger tight against the flat side of the
pawl. Slide the ashdoor handle shaft through its
hole in the ashdoor. Slide the pawl onto the shaft
so that the pawl offset is opposite the handle curve.
Ensure that the pawl is against the door and that
the handle turns without binding. Tighten the set
screw in the pawl. Thread the jam nut onto the
handle shaft and tighten it against the pawl.
Position the ashdoor between the bottom hinge
panel and the bottom of the stove; slide the
ashdoor hinge pin upward through the bottom
hinge, through the ashdoor, and into the socket of
the Allen bolt holding the left leg to the stove
bottom. Secure the hinge pin with a clevis pin just
above the bottom hinge.
27. Test the door seal with a ‘paper test’, closing the door on a slip of paper and latching
the door. The easier it is to pull the paper out, the looser the seal is at that spot.
Adjust the latch as needed to ensure a good seal all around the door. It latch
adjustments don’t provide a good seal, replace the gasket with a thicker one, or
remove it and apply a thin bead of stove cement to the bottom of the channel. Let this
bead dry before you replace the gasket before it hardens, resulting in a poor seal.
28. Install the ashpan bracket on the ashdoor. Secure it with two ¼-20 x ½” hex bolts and
washers. Close and open the ashdoor. If the bracket hits the ashlip, adjust it as
needed by tapping the bracket or twisting it. Insert the ashpan and re-test the ashdoor
operation to ensure that there’s no impact between the pan and anything else.
29. Paint the front doors, and then assemble them. Mask the gasket channels to avoid
over-spray. Re-gasket them if necessary. Put them facedown on a flat surface, and
install the glass. Check the edges of the glass for markings indicating the coated side
of the panes; the coated sides go outward, away from the fire. Install the air
manifolds.
30. Install the flue collar. It mounts with two Phillips round-head bolts, and nuts inside
the stove.
31. Prepare the stove for painting. Clean up any excess cement with a putty knife, and
mask the handles, the secondary air cover, and the safety plate. It’s better to apply
two light coats of paint than one heavy coat.
32. Install and adjust the front doors. The latch assembly adjusts with one turn of the
handle faucet. Remove the small Allen socket-head bolt from the right door to allow
the faucet to spin fully. Use the paper test here to ensure that the doors provide a
snug seal all around, including where the right door overlaps the left door.

33. Install the griddle. Gently tap the perimeter of the griddle to seat it against the gasket.
34. If you have replaced any major iron panels, tell the customer to re-cure the stove with
a series of four small fires, each hotter and longer than the last, to acclimate the iron
to the stresses of heat.
GASKETING
If you are replacing gaskets as part of standard maintenance, refer to the Maintenance
Section of the Owner’s Guide.
If you are replacing all gaskets as while re-building a firebox, follow the instructions
given below. Prepare parts carefully. Channels must be free of old gasketing, cement
and paint, and free of dust.
Use high quality gasket cement.
**Work in an area where there is plenty of light and a level work surface. Wear gloves
and protective eyewear.**
If you will install gaskets on clean, new parts, start with step 3. If you are going to re-
gasket old parts, they will need to be cleaned. Start with step 1.
1. Remove old gaskets. If the ends of the gasket meet, note where the joint is.
2. Clean the channels. Use a hammer and cold chisel or screwdriver to remove old
cement. Vacuum the channel to remove dust.
3. Choose the correct size gasket. Cut it to the right length, allowing an inch extra for
trimming.
4. Wipe the channel to be gasketed with a damp cloth. Place an unbroken 1/8” bead of
cement in the channel. Avoid using too much cement. The cement should not
saturate the gasket, just hold it in place.
5. Starting with one end, lightly press the gasket into the cemented channel. Trim
excess gasket with shears or side cutting pliers. Do not leave any ragged ends. If the
ends of the gasket meet, there should be no gaps or overlaps. Do not stretch the
gasket as this will make it too thin. A thin gasket may not make a good seal.
6. If possible, place the gasketed part against the surface it will meet. This will seat the
gasket evenly.
7. Clean any excess cement that has squeezed out around the gasket.

8. After installing new gaskets, it may be necessary to make adjustments on the damper
or load door. Refer to your Owner’s Guide.

Gasketing the Damper/Upper Fireback
1. Remove the throat hood from the fireback by swinging it upward and then sliding it
to either side (Fig. 25).
Fig. 25 Removing the Throat Hood Fig. 26 Removing the Wedges
2. Remove the left and right wedges that hold the lower fireback in place, and remove
the lower fireback (Fig. 26)
3. Remove the left and right inner walls – each has a hex-head bolt at top and bottom.
These inner walls are gasketed so you’re not breaking a cement seal here. You may
need to pry these walls out with a screwdriver going into notches at their forward
edges--if the stove is enameled, protect the surfaces near the notch.
4. Remove the Allen bolt from the damper handle, and slide the handle off.
5. Remove a hex-head bolt from each side of the stove’s outer back, near the top.
6. Remove the upper fireback assembly through the firebox. You may need to use a
large screwdriver to pry it loose from the stove back. As you face the stove, remove
the right-hand end first.
7. Remove the damper from the upper fireback by removing bolted tabs at each end.
8. Remove the original gasketing by pulling it out of its channel, and then clean the
channel with a wire brush.
9. Apply a narrow bead of stove cement to the bottom of the gasket groove, and lay the
gasketing into the channel. Do not stretch or bunch the gasket unless you need to
compensate for parts that have changed shape slightly. Close the damper and lock it
closed; check the seal with a slip of paper to ensure tightness. Leave the damper
closed for a few hours if you can, to ensure that the cement sets up well.
10. Work in reverse order to re-install the upper fireback; apply cement to the backs of
the ends of the upper fireback before re-installing.
