○ Separate chimneys are recommended when connecting the Hmf150/200 to a pre existing oil furnace. if
a single chimney is used in this application it must be 7" (178 mm) in diameter and approved for use with
wood burning appliances (2100°f) (1149°C).
○ The exhaust pipe from the wood flue must connect to the chimney below the junction of the oil
exhaust to the common chimney.
6.4.1 Controlling Draft
○ Whether the flue from the Hmf150/200 wood furnace has a dedicated chimney or it shares a
chimney already in place for an existing oil fired furnace the following conditions apply:
○ The use of incline manual dampers are forbidden.
○ barometric dampers will be installed where stack pressures exceed 0.06" w.c. (15 Pa) but
shall not prevent a minimum of 0.04" w.c. (10 Pa) for the chimney draft of the wood furnace.
○ The use of incline manual dampers are forbidden.
6.4.2 Measuring Draft
using a manometer with appropriate scale range connect testing tube between manometer and
chimney connector. end of testing tube should be inserted in chimney connector so approximately
1" (25 mm) of tube protrudes into and perpendicular to exhaust stream. This measurement shall be
taken approximately 12" (305 mm) above elbow/T attached to the furnace flue. Any hole made in
the chimney connector for insertion of manometer tube shall be adequately sealed with high temp
materials when testing is complete.
CHIMNEY DRAFT gREATER THAN 0.06" W.C. (15 pa) MAY CAUSE AN UNCONTROLLABLE FIRE AND
