2 Figure 1. Draft Gauge

Mounting the Instrument

For portable use stand the gauge on a reasonably level surface
convenient to the location for checking draft. Gauge may also be
hung in an upright position using Ë(Slotted Recess) to receive a
nail or screw head. For permanent installation remove Ì (Screws)
and front cover, fasten to panel with two number 8 screws thru
Í(Mounting Holes), replace front cover and Ì (Screws). Never
locate gauge where temperature exceeds 110° F.

Connections

For portable use connect the gauge to a furnace with the 9 foot
length of rubber tubing and metal draft tube provided. For per­manent installation, make connection from panel to draft mea­suring point with copper tubing or pipe, solid tubing (no fi ttings)
is preferred. At the end of the tubing provide a small tee with
a short piece of rubber tubing as shown in Figure 3. Connect­ing lines over 50 feet in length is not recommended. Use as few
bends as possible, and keep the connecting line to a minimum
length. The following tubing sizes are recommended:

Up to 10 foot length 1/4 inch ID tubing
Up to 25 foot length 3/8 inch ID tubing
Up to 50 foot length 1/2 inch ID tubing

Zero Adjusting

When checking for zero, hold the draft tube near gauge or if
permanently connected, break connecting line at panel. Zero is
adjusted by moving É(Adjusting Tab) until the pointer is in line
with the scales zero. For portable use, check zero each time the
gauge is set up for use. For permanent installations (always dis­connect the hose from the gauge before making the zero check)
check zero at one or two week intervals. 3
