3. Backpuffing
4. Smoke Rollout when Heater
Door is Opened
5. Low Catalytic Temperature
COMBUSTOR-RELATED
PROBLEMS
1. Plugging
2. Catalyst Peeling
3. Catalyst Masking
COLORED-GLASS
PROBLEMS
1. Glass Darkens
1. Gusts of wind / windy day
2. Hot combustor. (Above 1400
1. Bypass damper is closed
2. Opened door too soon after
opening bypass damper
3. Wind gusts blowing
1. Bypass is open
2. Light-off not obtained
3. Fuel charge is spend
4. Combustor coated with fly ash or
soot
5. Heater damper down too much
1. Burning materials that produce a
lot of char and fly ash
2. Burning wet, pitchy wood or
burning large loads of small-
diameter wood with the
combustor in the operating
position without light-off taking
place
1. Extreme temperatures at
combustor surface can cause the
catalyst to peel. Over-firing and
flame impingement are primary
causes
1. Not maintaining light-off
temperatures
1. Buildup Creosote on Glass

1. If flue cap not on chimney,
install one.
o
F) 2. Increase the amount of
combustion air slowly
1. Open bypass damper
2. Open bypass damper– wait 15
-30 seconds before slowly
opening door
3. Install flue cap
1. Once light-off temperatures
have been reached and unit is
stabilized, close bypass
Follow manufacturer's
2.
operating instructions
3. Refuel as necessary for
combustor operation
See Section VII "Preventive
4.
Maintenance"
5. Ensure that proper air mixture
and draft are available for
wood to burn proper
1. Do not burn materials such as
garbage, gift wrap or
cardboard
2. Burn dry, natural seasoned
hard wood. Don't place the
combustor in the operating
position until high
temperatures are high enough
to initiate light-off
1. If severe, remove and replace
catalysts. See "Catalyst
Replacement" Section VI.
Avoid extreme temperatures
1. See Section VI and review
operating instruction.
1. Cleaning Glass.
The glass inside will become
colored during use from creosote
buildup. The best way to clean
glass, COLD STOVE, is to let
creosote buildup harden. Then
use razor blade to scarp of
buildup of creosote. Wash glass
using soppy water or glass
cleaner.
