OIL BURNER OPERATION
NOTICE: For reliable operation, set Air-Fuel mixture conservatively based on installation conditions. CO
draft readings should be taken through the over fire test port in front jacket opening at right of burner (see FIG. 6). A 1/4"
O.D. sample tube must extend at least eight (8) inches into front cover to obtain accurate readings. Smoke test and stack
temperature should be taken at flue outlet. A test port in the flue box is provided to measure draft loss and smoke.
NOTICE: For accurate efficiency calculations, measure flue gas temperature in flue box sample port.

* Although the Ascent Combi Boiler can operate without a trace of smoke above 14% CO
the nominal gain in efficiency may not offset the potential of increased maintenance costs.

For combinations of above, use lowest CO

Draft at the breech with a chimney should be -0.02" to -0.12" w.c. on the EK1T Ascent Combi.
If not, recheck chimney, chimney base and flue pipe for blockage or clean out door openings.
Draft over fire with a power vent (sidewall vent) should be negative.
If not, check power vent fan is turning, or vent blockage.
