12. Soot and Fly Ash: Formation & Need for Removal in
Exhaust Venting System.
•
Frequency: Prior to each burn season and after
prolonged shut down.
•
By: Qualified Service Technician/Homeowner
The products of combustion will contain small particles
of flash. The flash will collect in the exhaust venting
system and restrict the flow of the flue gases. Incomplete
combustion, such as occurs during startup, shutdown,
or incorrect operation of the room appliance will lead
to some soot formation which will collect in the exhaust
venting system. The exhaust venting system should be
inspected at least once every year to determine if cleaning
is necessary.
The venting system may need to be cleaned at least once
a year or more often depending upon the quality of your
fuel or if there is a lot of horizontal pipe sections. Ash will
build up more quickly in the horizontal sections.
13. Preparing Firebox for Non-Burn Season
•
Frequency: Yearly at end of burn season
•
By: Homeowner
a. The appliance must be in complete shutdown and
allow the appliance to completely cool down.
b. Remove all ash from firebox and vacuum
thoroughly.
c. Paint all exposed steel, including cast-iron. Use
the Touch-Up paint supplied with the appliance or
purchase paint from your local dealer. You must
use a high-temperature paint made specifically for
heating appliances.
d. Cleaning the flue at the end of the burn season will
prevent corrosives to build-up and damage the flue.
e. Outside temperatures should have no affect on
the performance of the appliance under freezing
conditions.
14. Creosote Formation: Guidance on minimizing
•
Frequency: Periodically during heating season
•
By: Qualified Service Technician/Homeowner
This chimney should be inspected periodically during the
heating season to determine if a creosote build-up has
occurred. If a significant layer of creosote has accumulated
(3mm or more) it should be removed to reduce the risk of
chimney fire.
This appliance is required to be cleaned frequently
because soot creosote and ash may accumulate.

NOTE
D. Soot or Creosote Fire
Establish a routine for the fuel, wood burner and firing
technique. Check daily for creosote build-up until
experience shows how often you need to clean to be
safe. Be aware that the hotter the fire the less creosote is
deposited, and weekly cleaning may be necessary in the
mild weather even though monthly cleaning may be enough
in the coldest months. Contact your local municipal or
provincial fire authority for information on how to handle a
chimney fire.
In the event of a soot or creosote fire, close the firebox
door, exit the building immediately and contact the
proper fire authorities.
DO NOT under any circumstances re-enter the building.
E. High Ash Fuel Content Maintenance
•
Frequency: When the ash build-up exceeds the half
way point in the fire pot
•
By: Homeowner
If the ash build-up exceeds the half way point in the fire pot
before it automatically cleans, then the fire pot is not being
cleaned often enough.
Another symptom is if clinkers are adhering to the sides of
the fire pot.
Double check the wall control to ensure the proper setting
has been selected for the fuel you are burning. If that is
correct, change the setting to "Utility Pellet".
NOTE: You will need to empty the ash pan more
frequently if using the "Utility Pellet" setting.
Fire Risk
•
High ash fuels, or lack of maintenance, can
cause the fire pot to overfill. Follow proper
shutdown procedure if ash build up exceeds
half way point.
•
Failure to do so could result in smoking,
sooting and possible hopper fires.
