E. High Ash Fuel Content Maintenance
• Frequency:
When the ash build-up exceeds more than
half way up the fire pot.
• By:
Homeowner
Poor quality pellet fuel, or lack of maintenance, can create
conditions that make the fire pot fill quickly with ashes and
clinkers.
This condition makes the appliance susceptible to
overfilling the fire pot with pellets which may result in
smoking, sooting and possible hopper fires.
Figure 22.1
shows an example where the fire pot overfills, pellets back
up into the feed tube and ash has accumulated in the
firebox.
An inefficient and non-economical method of burning of fuel
caused by poor quality pellet fuel is shown in
Figure 22.2
.
The correct flame size when good quality, premium pellet
fuel is burned is shown in
Figure 22.3
.
If the ash buildup exceeds the half way point in the fire pot
IMMEDIATE ATTENTION AND CLEANING IS REQUIRED.
D. Soot or Creosote Fire Awareness
The 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
(1/8 inch [3mm] or more) it should be removed to reduce
the risk of chimney fire.
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.
