This appliance is a gas-fi red direct vent cast aluminum

hot water boiler. A revolutionary cast aluminum heat

exchanger means better heat transfer and thermal storage

contribute to a cleaner and healthier environment.

This appliance has been equipped for residential

installations. If used for commercial applications, any and

all additional code requirements must be adhered to for

installation. This may require additional controls, including

but not limited to a manual reset low water cut off, a

manual reset high temperature limit, and wiring and/or

piping modifi cations.

The manufacturer is not responsible for any fi eld

installation changes made to a boiler installation which are

installation codes and good industry practice.

Before servicing the boiler, allow it to cool. Always

shut off any electricity and gas supply connected to the

boiler prior to servicing.

Inspect gas line for leaks.

Be certain gas input rate is correct. Over-fi ring may

result in early failure of the boiler components. This

may cause dangerous operation. Under-fi ring may

result in too much air for the pre-mix burner causing

poor or loss of combustion.

effi cient and safe operation.

Keep boiler area clean of debris and free from

combustible materials, gasoline and other fl ammable

vapors and liquids.

Proper through-the-wall or through-the-roof

combustion venting shall be in accordance with the

materials and methods described in this manual.

Installation must comply with local codes.

This boiler and related hot water heating systems are

not do-it-yourself items. They must be installed and

This appliance, unlike normal residential atmospheric and

induced draft units, takes its combustion air directly from

the outdoors (sealed combustion) and does not compete

with building occupants for fresh air. Sealed combustion

(also known as “direct vent”) is the safest and best way

to obtain plenty of clean combustion air. The forced draft

fan draws in the outside combustion air to mix with gas,

which fl ows into the pre-mix burner and combusts. The

fan then forces the resulting fl ue gases from the boiler unit

and provides a positive removal of the fl ue gases from the

must be used for boiler installation. Accessibility

clearances may be achieved with use of removable

walls or partitions.

Boiler is approved for installation in closets and on

combustible fl oors. Boiler shall NOT be installed on

carpeting.

Clearances shown in Table 4 indicate required

Advise owner of boiler to keep venting and combustion

service (circulator replacement, condensate trap,

control replacement, etc.).

Boiler must be located where ambient temperatures

(minimum possible room temperatures where boiler

is installed assuming boiler is not in operation and

therefore contributes no heat to space) are always

at or above 32°F (0°C) to prevent freezing of liquid

condensate.

Boiler requires dedicated direct vent system. In direct vent

for required clearances.

If concentric vent termination is being used, refer to

for proper setup.

When an existing boiler is removed from a common

venting system, the common venting system is likely to be

too large for proper venting of the appliances remaining

connected to it. At the time of removal of an existing boiler,

the following steps shall be followed with each appliance

Visually inspect the venting system for proper size and

horizontal pitch and determine there is no blockage

or restriction, leakage, corrosion or other defi ciencies

which could cause an unsafe condition.

In so far as is practical, close all building doors and

windows and all doors between the space in which the

appliances remaining connected to the common venting

system are located and other spaces of the building.

Turn on clothes dryer and any appliance not connected

to the common venting system. Turn on any exhaust

fans, such as range hoods and bathroom exhaust, so

they will operate at maximum speed. Do not operate a

summer exhaust fan. Close fi re dampers.

Place in operation the appliance being inspected.

Follow the lighting instructions. Adjust thermostat so

appliances will operate continuously.

Test for spillage at the draft hood relief opening after 5

minutes of main burner operation. Use the fl ame of a

burning appliance to their previous condition of use.

Any improper operation of the common venting system

should be corrected so the installation conforms with

the National Fuel Code, ANSI Z223.1/NFPA 54, or

Natural Gas and Propane Installation Code, CAN/CSA

B149.1. When resizing any portion of the common

venting system, the common venting system should be

resized to approach the minimum size as determined

using the appropriate tables in chapter 13 of the

National Fuel Code, ANSI Z223.1/NFPA 54, or Natural

position with an appliance dolly or 2-wheel hand truck.

The dolly or hand truck should be inserted under the right

hand side of the boiler. It is possible to slide the boiler for

a short distance on a smooth fl oor or surface.

Run 14 gauge or heavier copper wire from boiler to

grounded connection in service panel or properly driven

and electrically grounded ground rod.
