range is between 70°F to 100°F. A lower temperature rise usually results in a higher system efficiency.

: If the temperature rise exceeds 100°F, the heat exchanger may fail, voiding the heat exchanger warranty resulting in property damage, personal injury or loss of life.

M. FLUE GAS COMBUSTION ANALYSIS

: Burner adjustments must be confirmed by instrumentation. Failure to use accurate or calibrated instrumentation to correctly setup the burner may result in reduced efficiency, sooting, and/or the production of hazardous carbon monoxide gas.

For typical burner combustion analysis results, refer to the table below.

Cottage Base Model: OMCCOT-BASE IMPORTANT: Adequate combustion air must be provided under all circumstances. If the underside of the home is skirted or enclosed e.g. by an enclosed crawlspace, the combustion air intake should exit through the side of cottage base and terminate outside of the structure. All joints and seams of supply ducts and combustion air ducts must be closed with a sealing method suitable to the application conditions and temperatures e.g. using high temperature silicone caulk and/or aluminum tape E. ALCOVE INSTALLATION F. CLOSET INSTALLATIONG. COMBUSTION AIR The preferred location of the outside combustion air intake termination e.g. an optional stainless steel intake hood, part no.370183 is through the side of the structure, skirting or enclosure. An alternate termination location is under the structure in the skirted or crawlspace area providing a minimum of 50 square inches of free area exists around the perimeter for outside combustion air to be drawn through. NOTE: Combustion air cannot be drawn from the occupied space of the home Figure H. FUEL PIPING 2.

After the furnace is warmed up to a steady- state condition about 15 minutes, the final burner adjustment should be made using combustion instrumentation for measuring carbon dioxide CO2 or oxygen O2, carbon monoxide CO, smoke for oil furnaces, and stack temperature.
