Installation Instructions
Install feeder as illustrated. If boiler tappings for equalizing pipes
“A” and “B” are not available, connect either one or both as
shown by dotted lines. Install with “water line” mark on fl oat
chamber on a level with the middle try-cock, or about halfway
up the gauge glass. Connect water supply line “C”. If a strainer
is used, install it in this line.
Install by-pass “D” so that boiler can be fi lled by hand, if neces-
sary.
All valves should be tight-closing and of good quality. Leaky
valves will fl ood boiler. Blow down fl oat chamber at least once
a week by opening valve “F” and letting water run for a few
minutes.
A shutoff and check valve must be installed in the water supply
line “E”.
