1 A. INST ALLA TION SEQUENCE F ollow the installation instructions provided in this manual in the order shown. The order of these instructions has been set in order to provide the installer with a logical sequence of steps that will minimize potential interferences and maximize safety during boiler installation.
2 A. ACCESSIBILITY CLEARANCES Install boiler not less than 24 ″ (610 mm) between the left side, top, and front of the boiler and adjacent wall or other appliance, when access is requir ed for ser vicing. B. CLEARANCE FROM COMBUSTIBLE CONSTRUCTION The design of this boiler is cer tified for closet installation with the following clearances: 1.
3 where: I fan = Input of the fan assisted appliances in Btu/hr ACH = air change per hour (per cent of the volume of the space e xchanged per hour , expr essed as a decimal) F or appliances other than.
4 ii. Where communicating with the outdoors through horizontal ducts, each opening shall have a minimum free ar ea of 1 in 2 per 2000 Btu/hr (22 cm 2 per 2000 W) of total rated input for all appliances in the space.
5 c. Each of the appliances ser ved shall be interlocked to the mechanical air supply to prevent main burner operation where the mechanical air supply system is not in operation.
6 BOILER SET -UP 1. Provide a sound, level foundation. Locate boiler as near to the chimney or outside wall as possible and centralized with respect to the heating system. 2.

15 VENTING E. BOILER REMO V AL FROM COMMON VENTING SYSTEM At the time of r emoval of an existing boiler , follow these steps with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation: a.
16 1. Size and install the gas supply piping properly in order to provide a supply of gas sufficient to meet the maximum demand without undue loss of pressur e between the meter and the boiler . 2. Determine the volume of gas to be provided to the boiler in cubic feet per hour .
17 T able 5.3: Pipe Capacity Capacity of pipe of different diameters and lengths in cubic feet per hour [cubic meter per hour] with a pressur e drop of 0.3 inches of water [75 kP a] and a specific gravity of 0.60. No allowance for an ordinary number of fittings is requir ed.
18 A. WIRING 1. See Figur e 6.1 for location of wiring and controls. Use Figur e 6.2 to connect the boiler to a power supply and to connect components to the boiler . 2. Connect the boiler by a separate, permanently live electrical supply line with a fused switch.
19 D . SEQUENCE OF OPERA TION 1. Thermostat calls for heat, energizes Control Relay (CR). 2. Control Relay (CR) energizes circulator . 3. Limit senses boiler water temperature. P revents boiler operation until water temperature falls appro ximately 15 ° F (8 ° C) below the cut-out temperature.
