VERtICAL fLUE:
1. Adjustment weight must be in RIGHT HAND SLOT
(marked "V") in bracket on gate.
2. The arrow on flap at bottom of gate must line up with letter
"V" on lower right part of gate. If it does not, remove flap,
turn over and snap onto gate again.
Flap can be removed by inserting small screwdriver at the back
side of the gate between the gate and the flap, then pulling
downward on flap.
HoRIZoNtAL fLUE:
1. Adjustment weight must be in LEFT HAND SLOT
(marked "H") in bracket on gate.
2. The arrow on flap at bottom of gate must line up with letter
"H" on lower left part of gate. If it does not, remove flap,
turn over and snap onto gate again.
Bend outward the two ears at the front corners of collar and insert
clamping screw. Bolt the remainder of the collar together. See
Figure 2. Hold the collar against the flue in the EXACT position
and mark the outline of the collar on the flue. Cut a hole in the flue
about half an inch smaller than the marks.
Then cut a series of short slits (about 3/8" or 1/2" deep) around
the edges of the opening. After the collar is strapped on the flue
the cut edges can be bent outward into the collar and thus make
a better joint. WHEN FINISHED, THE OPENING INTO THE FLUE
MUST BE EQUAL IN SIZE TO THE COLLAR OF THE DRAFT
CONTROL. If flue pipe is made of material too heavy to bend out
into the collar, the opening into the flue must be within 1/4" of the
same diameter as the collar.
Strap the collar to the flue pipe and place the draft control into the
collar, fastening it there by tightening the clamping screw in the
collar.
Use a spirit level to make sure that the control does not lean for -
ward or backward but instead is plumb in both directions, regard-
less of whether the flue is horizontal, vertical or sloping.
INItIAL SEttING of BARoMEtRIC CoNtRoL
Set the control at a maximum of .03 or as low a draft as will
give good combustion and meet the requirements for heat. Turn
adjustment weight counter-clockwise to loosen, then slide in slot
to proper position and tighten. Bracket is marked 2, 4, 6, and 8,
which indicates draft settings of .02, .04, etc. (These are drafts in
flue adjacent to control, not over-fire drafts.) A monometer must be
used to accurately adjust flue draft.
