Section H- Operation and maintenance
(continued..)
5. The slide type air controls can be slid open to allow more air to the fire, thus
increasing the fire size, rate of burn, and heat produced. Likewise, sliding the
air controls closed or decreasing the air to the fire decreases the fire size, rate of
burn, and heat produced.
6. Never leave your stove unattended with the door open. When the stove door is
open it will be necessary to open the by-pass to prevent smoke spillage.
7. CAUTION: When building the first couple of fires be careful to build the fire
small and increase heat slowly over a 4-5 hour period. The paint on the stove
“cures” with heat and this process needs to be done slowly. As the paint
“cures” it gives off a smell of paint and sometimes a visible “smoky” haze in
the room. Make sure the area is well ventilated during the curing operation.
The smell will disappear after a few hours of operation.
Section I- Catalyst Replacement
Gasket Replacement:
Periodically, gasket on your wood stove will need to be replaced. The
following is a list of parts and sizes of gasket used:
1) Door Gasket: 5/8” diameter (5 ft.)
2) Glass Gasket: Window channel with adhesive (5 ft.)
3) Catalytic Gasket: 1/16”x 3” (8 ft.)
4) By-pass Gasket: 1/8”x 1 1/2” (3 feet required)
*SEE FIGURE 1 FOR LOCATIONS OF GASKET*
CATALYTIC REPLACEMENT STEPS:
1) Pull insert or stovepipe out.
2) Remove by-pass rod by unscrewing fastening nuts. (A)
3) Lubricate and remove the 4 main holding bolts. (B) You may need to
support the baffle before doing this, as it is heavy.
4) Remove entire catalytic baffle system from stove.
5) Lift off catalytic hold-down clamp noting location of all gasket. (C)
6) Slide catalytic units up and out. (D)
7) Rewrap new catalytic units with new 1/8”x 3” gasket, or replace with pre-
wrapped catalytic assembly in stainless steel enclosure.
8) Re-install catalytic units in place being careful to have a ‘snug’ fit. It
may be necessary to add more gasket to achieve a snug fit.
9) Replace catalytic hold-down clamp and re-gasket top area with gasket
(1/8”x 3”) as shown in Figure 1.
10) Re-install entire catalytic baffle system with 4 bolts and hook up by-pass
rod with nuts.
11) Double check bolts and fasteners for tightness.
Note: If the steel baffle (catalytic enclosure) system is warped or degraded, an
entire baffle system with catalytics and gasketing already installed may be ordered and
replaced as a unit. Contact your dealer.
