length of extended tube must not exceed
12 inches.

Location For Checking Draft

Heating Equipment Manufacturer may
require draft measurement (a) in fl ue

between furnace and draft regulator; (b)
overfi re between combustion space and heat
exchanger. Locate draft hole in fl ue at least
6" from draft regulator or damper toward
furnace. Use awl with ¼" shank to form hole
in fl ue or light sheet metal. Overfi re measure-
ment may be made through bolt hole or air
louvre in door or through observation port, if
necessary, drill a ¼" hole. In case of oversize
open-ing, Draft Tube should protrude several
inches minimum beyond inside wall, if neces­sary extend Draft Tube (see above).

Draft Measurement

while continuing to operate insert about half
of Draft Tube into draft hole. Cover Zero
Check hole Ìwith fi nger, level Draftrite until
(a) Draft Tube is horizon-tal and (b) pointer
is in line with zero scale mark, uncover Zero
Check hole without disturbing position of
Draftrite. Pointer instantly shows draft or
pressure reading. Use of the Draftrite is il­lustrated on front page.

Maintenance

Protect instrument from dirt, oil, and
lint. Do not oil. Keep gauge in case when
not in use, and keep case free of lint
or dirt. Clean Draft Tube occasionally

extreme portability is important.

draft for best performance. Specifi c draft
recommendation should be obtained from
manufacturer.
