PREINSTALLATION

1. PREINSTALLATION

NOTICE

The equipment shall be installed with those installation requirements of the authority having jurisdiction or, in the absence of such requirements, to the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CGA B149 Installation Codes.

Where required by the authority having jurisdiction, the installation must conform to American Society of Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired Boilers, ASME CSD-1.

Read these instructions carefully before beginning the installation.

Study the control folder and consult drawings.

A shipping list is enclosed with each boiler, listing the items packed at the factory. Check the list as you unpack parts. If any parts are missing or damaged, report the problem to the delivering carrier immediately.

Figure 1.1: Clearance Requirements

A.ACCESSIBILITY CLEARANCES

1.The following recommendations allow for reasonable access to the boiler. Local codes or special conditions may require greater clearances.

a.For servicing the boiler: provide 48" (1219 mm) between the control manifold and adjacent wall or other appliance.

b.For access to draft hood or passage to access the boiler control manifold(s): provide 48" (1219 mm) between the side of the boiler and adjacent wall or other appliance.

c.See Figure 1.1. Clearances with an “S” are minimum clearances for service accessibility.

B.COMBUSTIBLE CONSTRUCTION CLEARANCES

1.This boiler is design certified for the following clearances to combustible construction.

• 24" (610 mm) between the front, top, sides and rear of the jacket.

•6" (152 mm) from steam and hot water pipes

•6" (152 mm) from vent connector

•See Figure 1.1. Clearances with a “C” indicate minimum clearances from combustible construction.

C.AIR FOR COMBUSTION AND VENTILATION

1.Adequate combustion air and ventilation air must be provided for this appliance in accordance with the section of the National Fuel Gas Code entitled, “Air for Combustion and Ventilation” or applicable provisions of the local building code. Subsections 2 through 8 as follows are based on the National Fuel Gas Code requirements.
