DRAFT SLIDE GATE ADJUSTMENT
(Optional equipment)
If installing and using the Draft Slide Gate: The slide gate does not come with the furnace. It must
be purchased separately if needed.
The normal operation of the Magnum would be with the Draft Slide Gate open fully as shown. When the
gate is in the fully open position, the plate will be against the mounting plate as shown.
If the unit needs a draft correction adjustment, the bolts are loosened and the slide gate is rotated a few
degrees at a time until the proper operation of the unit is achieved.
NOTE: This adjustment must be made by a qualified Magnum installer
When rotating the slide gate, be careful not to damage the gasket. Re-tighten the bolts and check for
leakes.
If your furnace burns with a lazy flame or does not appear to get enough draft, the draft gate is closed too
far. This adjustment should only be made if the furnace does not stay lit on the number one heat setting
and it has been determined that the installation, fuel, venting and operation of the unit is not causing the
problem.
When the unit is installed, make sure that the draft gate has not slid partially closed and is not loose.
