OPERATING INSTRUCTIONS
Supporting Gauge: (Optional - Not Supplied by Bacharach)
Clamp Bracket mounts on ¼ to 1-½ inch horizontal or vertical pipe. Where
Clamp Bracket is not available, Gauge can be supported by hand or propped against
vertical support while reading. In all cases, Gauge should be vertical while reading
for maximum accuracy (estimation by eye is suffi cient).

CONNECTING TO GAS LINE (Figure 1)
Turn OFF Main Gas Cock (6) to appliance. Remove Pipe Plug (7) from control
valve or gas line between regulator and burner. (Bush Plug opening larger than ¼
inch N.P.T. to ¼ inch.) Press tapered rubber Plug (8) with projecting metal Tube (9)
fi rmly into Plug hole with slight twisting motion. Open both Valves (10-11) one full
turn. Press tapered Plug (12) over right hand (facing front) Valve (11). Open main
Gas Cock (6) to appliance. Check pilot fl ame.

READING-ADJUSTING MANIFOLD PRESSURE (Figure 2)
Turn burner on (after checking pilot fl ame) either by advancing thermostat 5-10°
F, or by manual turn on at control valve. Slide Scale (14) up with Scale Knob (15)
until Zero Scale Arrow (16) is opposite top of low (right hand) liquid column.
Read gas manifold pressure on Scale opposite top of higher (left hand) liquid col-
umn (17). This is direct reading of pressure. Do not multiply this reading by 2.

To adjust pressure, remove Regulator Cap (18- Figure 1). Turn exposed screw
head clockwise to increase pressure, counterclockwise to reduce pressure. Adjust
manifold pressure to value recommended by local utility (service engineer) or
manufacturer of burner.
