1.Provide internal LED displaying the following boiler status/faults:

a.Steady on – Internal control failure

b.One flash – Air flow fault

c.Two flashes – Erroneous flame signal

d.Three flashes – Ignition lockout

I.Combustion Chamber: The lightweight, high-temperature, multi-piece, interlocking ceramic fiber combustion chamber liner shall be sealed to reduce standby radiation losses, reducing jacket losses and increasing unit efficiency.

J.Venting

1.When routed vertically, the boiler’s flue material and size shall be in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA54 latest edition (Category I).

2.When routed horizontally, the boiler(s) flue material and size shall meet or exceed the requirements as specified for Category III in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 latest edition.

3.The boiler(s) shall be TruSeal™ direct vent ready. The boiler(s) shall meet safety standards for direct vent equipment as noted by: the 2006 UMC Section 1107.6; ASHRAE 15-1994, Section 8.13.6; and ANSI Z21.13/CSA 4.9.

K.Cabinet

1.The corrosion-resistant galvanized steel jackets shall be finished with a baked-on epoxy powder coat which is suitable for outdoor installation, applied prior to assembly for complete coverage, and shall incorporate louvers in the outer panels to divert air past heated surfaces.

2.The boiler(s), if located on a combustible floor, shall not require a separate combustible floor base.

3.Combustion air intake shall be on the left side of the cabinet.

L.Operating Controls

1.The boiler(s) shall feature an optional controller.

Specifier Note: The remaining items in this section are options. Delete those that are not being specified.

M.Boiler Pump - Refer to Equipment Schedule

N.Cold Water Run System

1.The boiler(s) shall be configured with a cold water run automatic proportional bypass system that ensures the boiler will experience inlet temperatures in excess of 105ºF in less than 7 minutes to avoid damaging condensation. The unit will automatically shut down if the inlet temperature is not achieved within the 7 minute time frame.

2.The cold water run system shall be configured with a variable speed pump that is controlled by

asystem-matched PID control that injects the correct amount of cold water directly into the boiler loop to maintain a minimum inlet temperature. The PID controller temperature sensor shall be located in the inlet header of the boiler.

3.The control shall have a temperature setting dial located on the face of the board. The temperature range of the dial shall be 105ºF to 120ºF. The PID Logic shall be capable of limiting system overshoot to a maximum of 10ºF on initial start-up or call-for-heat.

4.The cold water run system shall be shipped loose for field installation.

5.The cold water run pump shall have the following diagnostic LED’s:

a.Power

b.Heat Request

c.Reduced Out

d.% Out

2.3SOURCE QUALITY CONTROL

A.The boiler(s) shall be completely assembled, wired, and fire-tested prior to shipment from the factory.

B.The boiler(s) shall be furnished with the sales order, ASME Manufacturer’s Data Report, inspection sheet, wiring diagram, rating plate and Installation and Operating Manual.
