4 3 III Before Installing 1 ) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict accordance with this manual and the requirements of the authority having jurisdiction.
5 4 4 ) Do not install this boiler in a location where gasoline or other flammable vapors or liquids will be stored or used. Do not install this boiler in an area where large amounts of airborne dust will be present, such as a workshop. 5 ) The boiler should be located as close to the chimney as possible.
6 For Buildings of Other than Unusually Tight Construction 1) Determine whether the boiler is to be installed in a confined space - A confined space is defined by the National Fuel Gas Code as having a volume less than 50 cubic feet per 1000 BTU/hr input of all appliances installed in that space.

9 8 VI V enting Vent installation must be in accordance with local building codes, or the local authority having jurisdiction, or the National Fuel Gas Code , NFPA 54/ANSI Z 223.1. A typical vent installation is illustrated by Figure 8. The components of vent installation are the vent damper (if used), vent connector and chimney.
10 9 1 4 ) Vent damper installation is mandatory on all sizes from the BSI069 to BSI276. The BSI310 through BSI379 may be ordered with or without vent damper. If supplied, install vent damper (see Figure 9) as follows: a ) Open vent damper carton and remove installation instructions.

13 12 CAUTION • INSTALL BOILER SO THAT THE GAS IGNITION SYSTEM COMPONENTS ARE PROTECTED FROM WATER (DRIPPING, SPRAYING, RAIN, ETC.) DURING APPLIANCE OPERATION AND SERVICE (CIRCULATOR REPLACEMENT, ETC.). • OPERATION OF THIS BOILER IN A SYSTEM HAVING SIGNIFICANT AMOUNTS OF DISSOLVED OXYGEN CAN CAUSE SEVERE HEAT EXCHANGER CORROSION DAMAGE.
14 Piping Installation 1) Remove parts bag from boiler crate. 2) Install safety valve (spindle must be in vertical position) into tapping on boiler left side (see Figure 1) using the 3/4” NPT nipples and elbow supplied.

16 IX Indirect W ater Heater Piping All BSI series boilers are equipped with tappings to permit the connection of a Crown Mega-Stor, or other indirect water heater. In this type of system, hot boiler water is drawn from below the water line and passed through the heat exchanger in the indirect water heater.
17 X Wiring 1) 120 V olt W iring - The boiler should be provided with its own 15A branch circuit with fused disconnect. All 120 volt connections are made inside the junction box on the left side of the boiler .
18 Feeder Wiring for Boilers Equipped with McDonnell & Miller #67 Low W ater Cut-offs Figures 14a and 14b show feeder wiring for McDonnell & Miller #101A, McDonnell & Miller WF2-U-24 and Hydrolevel VXT - 24 feeders on boilers equipped with #67 low water cutoffs.

24 XI S tar t-up and Checkout Use the following procedure for initial start-up of the boiler: 1 ) Make sure that the boiler is filled with water to the normal water line (28 3/4 inches above the floor or pad on which the boiler is installed) 2 ) Check all new gas piping for leaks and purge piping sections that are filled with air.
25 24 1 6 ) Check the manifold pressure and adjust if necessary. To do this, use the following procedure: a ) Connect a manometer to the inlet pressure tap on the gas valve (see Figures 23 and 24). b) Check the inlet pressure with all gas appliances on and off.
