Abstract
An inclined manometer particularly adapted for gauging the draft of a stove flue pipe is provided. The manometer is comprised of a pair of opposed open-ended legs mounted on a mounting plate. The legs are inclined at a relatively large angle from each other and are integrally joined at a midpoint nadir including an indenting recess. One terminal end of a first of the legs is received inside the flue pipe and a second terminal end of a second of the legs is opened to the ambient environment outside the flue pipe. The mounting plate includes a registry for identifying pressure differentials between the terminal ends. A selectively adjustable mounting bracket is employed for mounting the mounting plate to the flue pipe and for selectively leveling the manometer legs. A manometer fluid is provided consisting of ninety to ninety-seven percent propylene glycol and three to ten percent water with a trace of dye material.
