7-3 In Season Maintenance (continued)
ASH REMOVAL - Ashes must be removed from inside the heater on a routine basis.
Excessive ash buildup inside the ash box will reduce heating efficiency and can lead to
premature breakdown or warpage of the grates. When you remove the ashes, leave
approximately 1” of loose ash in the ash bin, this will give the coals that fall through the
grates a bed to fall on, and prevent the coals from warping the ash pan itself. The build
up of ashes in the firebox should be checked at least once a week. The build up of
ash and creosote in the firebox should be cleaned out regularly, never allow build up to
stay in the firebox. Allow the fire to burn down until the grates can be seen. This
insures that the grates are clear.
AIR PASSAGE - After you remove the ashes from the heater you need to check the
total air passage (from blower to stack ). Unplug the two wire power cord so the blower
will not accidentally come on while you are checking it. Raise the damper lid up on the
blower to check the blower wheel for any build up or obstructions. Raise the cleanout
lid on the main air tube going into the back of the heater, check for blockage, such as
ashes pushed into it when the ashes were shoveled out of the ash bin. Check the
grates for build up on top of grates that could block the flow of air to the fire. Check the
smoke stack for creosote build up. In the C5 model there is a baffle plate mounted in
the fire box directly below the smoke stack. This baffle plate can be removed for
cleaning. This baffle plate is laying across two (2) pipes in the top of the fire box and
can be slid to either side for removal. Any obstruction of the exhaust gases or the
supply air to the fire will make the heater not perform correctly. When finished checking
and/or cleaning plug in the power cord to put heater back in service.
7-4 Post Season Maintenance
Preplan when you want to shut your system down.
Allow your heater to burn completely out of fuel and cool down.
Turn off power to the heater. Unplug all power cords in the back of the heater.
Clean out all ashes from the ash bin area and any build up of ashes and creosote from
the firebox area. On the C5 model remove and clean the baffle plate in the top of the
fire box, clean out the smoke stack.
Ashes left in the firebox for extended periods can cause corrosion and shall void
the warranty.
