MAINTENANCE
Clinker formation can occur from a number of different causes or a combination of causes. Some of these are
as follows:
• Too hot a re (too much draft)
• Too shallow a bed of coals
• Too deep a bed of coals
• Excess shaking
• Poking the re from the top
• Poor quality coal – excess ash content
• Too little air (draft) after a long hot re
SAFETY
Whenever a loading door is opened, it always should be cracked slightly before fully opening to allow oxygen
to enter and burn any combustible gases that are present. Failure to do this could result in sudden ignition of the
unburned gases when the door is opened.
A furnace never should be lled with excess coal so that the ue gas exit is in anyway blocked or impeded.
Burning coal generates carbon monoxide. If the ue gas exit is blocked, the carbon monoxide can be forced
out of the furnace into the room with possible fatal consequences. Never burn coal in any furnace that does not
have an airtight, unied chimney system. The furnace should be used only with chimney systems that provide a
strong, reliable draft. With the exception of the start up period, an ash pit door never should be left open. Do not
use an automatic stoker with this furnace.
Failure to follow these instructions may result in poor efciency, excessive corrosion of the heat exchanger and
the possibility of a creosote re.
DAILY
Furnace model with grates must have the ashes removed daily. This is to prevent warping of the grates and
prevent any interruption in the combustion air ow. Ashes must be put in a metal container with a lid on it before
moving the ashes to the outdoors.
MONTHLY
Furnace heat exchanger and uepipe – Furnaces without grates must have ashes removed on a minimum of a
monthly basis depending on the ash build up. The complete heat exchanger and ue pipe should be thoroughly
inspected for creosote deposits, ash buildup, etc. Creosote or ash deposits must be removed by scraping and/
or brushing the deposits from the heat exchanger surfaces. An industrial vacuum cleaner may be used to assist
in the removal of such deposits. A complete cleaning must be done immediately at the end of each heating
season. If this is not done, condensation from the summer , or any other source, will mix with the ash or creosote
and cause corrosion of the heat exchanger. Corrosion is not covered under warranty.
NOTE: Establish a routine for the storage of fuel, care of the appliance, and ring techniques. Check daily for
creosote buildup until experience shows how often cleaning is necessary. Be aware that the hotter the re, the
less creosote is deposited and weekly cleaning may be necessary in mild weather even though monthly cleaning
may be enough in the coldest months. Have a clearly understood plan to handle a chimney re.
CHIMNEY
Chemical chimney cleaners are not recommended as they could damage the furnace heat exchanger and
ue pipe.
One of the most efcient methods to clean a chimney is to lower a stiff brush (chimney brush) tied to a heavy
weight down the chimney on a rope. Work the brush up and down the chimney to scrape the accumulated
creosote and soot off the chimney walls. Remove the residue from the cleanout at the base of the chimney.
SEMI-ANNUALLY
Draft Fan – oil motor with #20 non-detergent oil.
ANNUALLY
Burner Motor and Blower Motor – oil with #20 non-detergent oil. In the spring, after the furnace is shut down for
the summer, clean the heat exchanger of all soot, ash and creosote accumulation, remove all ashes, clean the
ue pipe and clean the chimney.
