a. Properly functioning catalysts will be exhibiting a uniform glow from one end to other (indicating
ignition).
b. Physically degraded catalysts will have cold places (areas not igniting) where plugging, crumbling or
other degradation has occurred. If this occurs, monitor probe temperature will not increase at a normal
rate. For further inspection it will be necessary to go by disassembly method as follows:
Disassembly Inspection Method: For thorough catalysts inspection, removal of catalyst housing is necessary
(cold heater only).
a. Spread a drop cloth in front of heater.
b. Open door and clean out any ash.
c. Open bypass door to give access to two rear mounting bolts.
d.
Using 9/16” wrench or 9/16” socket, loosen four bolts and remove catalyst housing (drop down) and place
in a suitable inspection area (it may be necessary to use penetrating oil if nuts and bolts have seized).
e. Inspect top and bottom side of catalysts for plugging, crumbling and other physical degradation.
1. If a problem exists, refer to Troubleshooting section of manual for possible cause of problem and
solution (including replacement if necessary).
2. Reassemble if catalysts are okay being sure stainless steel heat reflector is positioned back in its
original position and bolt housing and heat reflector securely back in place.
CATALYST REPLACEMENT
(Off-Season Replacement Recommended)
The catalysts in your stove are designed for many years of use. If after several years of use, efficiency of
stove decreases or if a notable increase in amount of smoke is observed, catalysts may need to be replaced. See
Catalyst Warranty prior to replacement.
