The air duct does not need to connect directly to the stove as the duct may terminate at the hearth top level. If air is accessed through the wall, remove the air cover at the stove pedestal back, and install a 4” or larger duct connecting the stove pedestal and the wall. A storm or dryer type vent with a screen is adequate. For your convenience, an outside air kit (part # 4OAVK) is available through your dealer. All mobile home installations require use of OCHM1 Manufactured Home Kit which includes an automatic oil valve shut-off control rod, return spring, and all fasteners. Complete mobile home kit installation instructions are included with this kit. For further help or questions, contact your dealer.

If you are not installing this stove in a mobile home, and outside air is not desired, simply remove the outside air cover at the pedestal back so ambient room air can enter. Please note that at certain draft conditions (i.e. high winds) a significant amount of air may be needed to achieve a proper burn. Consideration of open windows or an air source near the stove will probably be necessary depending on the “air-tightness” of your home. Again, outside air to your oil stove is a good idea as it will make the combustion impervious to house pressure problems.

*Please note that these clearances are minimums. It is a good idea to exceed these clearances unless space is limited. Common sense must prevail.

Minimum Clearances to Combustibles

	Sides	Back	Flue Pipe	Corner	Top
Standard	8”	6”	9”*	4”	—
Alcove	8”	6”	9”	4”	54”

Note: Corner clearance applies only when the stove is installed in a room corner with the stove placed perpendicular to the corner (45 degrees).

Note: On alcove installations, the maximum depth of the alcove is 30”.

*Clearances to flue pipe are for single-wall connectors. A double-wall connector is required for mobile home installations.

The flue and flue connections

Do not connect this unit to a flue servicing another appliance. It is of utmost importance that the flue be dedicated to the Oil Classic as the flue is, without a doubt, the most important component of the system. Good combustion is dependent upon the correct amount of air being supplied to the burner at all times, which is dependent upon a correct negative flue pressure. Draft is caused by the gases inside the flue being hotter and lighter than the air outside, thus the rising heated gases carry out the products of combustion. Since the flue “sucks” gases up the flue, it is this suction that draws air into the pedestal area to feed the burn pot with the air needed for an efficient, blue-flame burn. (continued…)
