1. GENERAL SPECIFICATION

Contractor shall furnish and install, where indicated on the drawings, ______ (quantity) Model
V-11H______, ______ (steam or water), ______ (#2 Oil, Nat. or LP Gas, #2 Oil and Nat. or LP Gas)
pressure fired boiler-burner unit(s), having an AHRI approved gross output of ______ MBH per boiler
and a net rating of _______ MBH with an burner capacity of _______ MBH (Gas) ______ GPH (#2 Oil).
Boiler(s) shall be constructed of cast iron sections manufactured in accordance with ASME requirements
for low pressure boilers and each section shall be permanently marked with the ASME symbol and the
maximum allowable working pressures. The boiler-burner unit shall not require a refractory combustion
chamber and the sections shall be of wet base construction. Further, the boiler-burner unit shall be
designed so that only a vent shall be required that extends only 3 feet above the highest point of the roof.

2. BOILER EQUIPMENT SPECIFICATION
*2.1 The boiler shall be furnished as a knocked down unit for field erection according to the

manufacturer’s instructions.

*(NOTE TO SPECIFIER: The V11H boiler-burner unit is shipped as standard with sections

unassembled. However, if job conditions permit, the following options are available.

*2.2 The boiler shall be furnished as a factory assembled and water tested section assembly with the

jacket, burner, and controls shipped separately.

*2.3 The boiler shall be furnished as a factory packaged boiler with jacket, burner, and controls
mounted and wired. Boiler shall be mounted on a steel shipping skid and entire package shall
be shrink wrapped.

*2.4 Factory packaged boiler shall be factory firetested.

2.5 Boiler shall be equipped with a flange mounted flame retention forced draft burner that has been
designed and tested for a minimum of 81.5% (Gas fired, water), 80.5% (Gas fired, steam) and/or

84.4% (Oil fired, water), 83.5% (Oil fired, steam) thermal efficiency based on AHRI testing
procedure.

2.6 The boiler-burner mounting plate shall be lined with lightweight refractory insulation and shall
have built-in observation port with closure cover.

2.7 Boiler sections shall have pin-like projections on each center section, evenly spaced on the
vertical flue with removable stainless steel flue baffles inserted between each row surfaces to extract
the greatest possible heating value from the hot flue gases.

2.8 Boiler sections shall be surface ground to ensure smooth positive mating surfaces.

2.9 Boiler sections shall be assembled with precision machined cast iron push nipples, pressed into a
mating machined nipple port in the section eliminating the need for any gasket material which would
be subject to deterioration due to corrosion or oil based chemicals. The sections are to be assembled
with short draw rods.

2.10 A gas-tight seal, which is imperative for forced draft boilers, will be achieved with the
application of a fiberglass rope gasket and silastic sealant in a finished ground groove between
sections.

2.11 Washout tappings shall be provided in both the front and back boiler sections. Blowoff tapping

shall be provided in the back boiler section.
*2.12 The front section of the boiler shall have (2) ½” gauge glass tappings for steam; thus eliminating

the need for a separate external type water column.

*2.13 The boiler shall be furnished with a 1-1/2” crown inspection/washout tapping on each side of each

section. Each tapping shall be furnished with a brass square head plug.

*2.14 Water boiler sections shall be individually hydrostatically tested for 80 psi water working pressure in

accordance with ASME Code Section IV.

*2.15 Steam boiler sections shall be hydrostatically tested in accordance with ASME Code Section IV.

2.16 Boiler shall have individual cleanout openings between sections covered with insulated steel
covers to insure a gas-tight seal.

2.17 Boiler flue canopy shall be constructed of heavy gauge aluminized steel and shall be concealed

under an insulated steel boiler jacket.

2.18 The boiler flue connector shall be (rear)(top) outlet and securely fastened and sealed to the
canopy and shall contain a lock-type adjustable damper with test tapping.

2.19 The boiler jacket shall be constructed of heavy gauge steel (20 ga.) with 1” insulation and have a rust
resistant baked enamel finish. The jacket shall be capable of being installed after system piping has
been connected to the boiler section assembly. Jacket will have removable side panels so that the
jacket can be removed for cleaning without removing any screws or disturbing the system piping.

2.20 The boiler shall be furnished with a rear flame observation port (spring loaded pressure relief
door with built-in observation port - optional).

*2.21 Water boiler trim shall include a 3-1/2” round pressure-temperature gauge with separated scales for

pressure and water temperature. In addition, an ASME approved safety relief valve shall be
furnished sized to exceed the boiler gross output capacity and shall be factory set to relieve pressure
at (30) (50) (80) psi.

*2.22 Steam boiler trim shall include a 3-1/2” round steam pressure gauge with internal siphon device. A

water level gauge glass shall be furnished with a flush and drain valve in bottom connection. In
addition, an ASME approved safety valve shall be furnished with side outlet porting set to relieve
pressure at 15 psi. The safety valve shall be sized to exceed the gross output of the boiler.

*(NOTE TO SPECIFIER: Tankless heaters for domestic water supply are available for the V-11H steam

or water boilers. Because of the wide variety of ratings (8 to 72 GPM), dependent on boiler size,
please refer to current V-11H installation manual or trade price book for exact quantity, heater
number rating and control arrangements available. If a tankless heater is desired, we suggest the
following paragraph be added.)

*2.23 The boiler shall include _______ (quantity) tankless heater(s) number V11-2 with a total continuous

draw rating of _______ GPM of water raised from 40° to 140°F with 200°F boiler water
temperature.

3. BOILER CONTROLS

3.1 High limit control (a) or (b) below:

(a) shall be automatic reset type suitable for 115 volt 60 Hz.
(b) shall be manual reset type suitable for 115 volt 60 Hz.

3.2 A separate operating control shall be furnished by the contractor in addition to the high limit

control and shall be automatic reset type suitable for 115 volt 60 Hz.
