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 necessary.

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”.
