To optimize the efficiency of your furnace, here are few advices you should follow when installing or operating
your Hotblast 1950 furnace.
Respect the local codes (when in doubt, consult your local dealer).
Make sure your furnace is installed according to the instructions on the certification plate.
All controls adjustments must be performed by a qualified technician. The controls settings and the blower speed
must conform to the recommendations of the National Warm Air Heating and Air Conditioning Association and
respect the recommended static pressure ranges in the warm air bonnet of the furnace (see General Technical
Data, static pressure).
1. CHIMNEY AND DRAFT
This furnace must be connected to a chimney certified for wood burning heating appliances; a 7 inch connector is
highly recommended for your Hotblast 1950.
If draft exceed –0.06 in. W.C a barometric damper should be installed on the smoke pipe.
Never install a manual damper.
The barometric control must be adjusted so that the maximum draft measured at the furnace outlet does not
exceed -0.06 in. w.c. Please note that a draft exceeding -0.06 in. w.c. could produce an uncontrollable fire. On the
other hand, the minimum draft required is -0.04 in. w.c. in the evacuation pipe.
