1) Boiler Input Rate is determined at minimum vent length. The rate will decrease as vent length increases.

2) Parameter 17 is set to 2,250 at elevations of 2,000 feet above and below.

3) Parameter 17 must be raised to 3,200 at altitudes or elevations of 2,000 feet and above.

These low pressure gas-fired hot water boilers are design certified 

by CSA International, for use with natural and propane gases. The 

boilers are constructed and hydrostatically tested for a maximum 

working pressure of 50 PSIG (pounds per square inch gauge) in ac-

cordance with ASME (American Society of Mechanical Engineers) 

Boiler and Pressure Vessel Code Section IV Standards for heating 

boilers.
The Boilers are certified in accordance with ANSI (American Na-

tional Standards Institute) Z21.13 standards as gas-fired, direct vent, 

condensing, hot water boilers.
The Heating Capacity indicates the amount of heat available after 

subtracting the losses up the stack. Most of this heat is available to 

heat water. A small portion is heat loss from the jacket and surfaces 

of the boiler, and it is assumed that this heat stays in the structure. 

The Net I=B=R Rating represents the portion of the remaining heat 

that can be applied to heat the radiation or terminal units (i.e., finned 

tube baseboard, cast iron radiators, radiant floor, etc.) The difference 

between the Heating Capacity and the Net I=B=R Rating, called 

the piping and pickup allowance, establishes a reserve for heating 

the volume of water in the system and offsetting heat losses from 

the piping. The Net I=B=R Ratings shown are based on a piping 

and pickup factor of 1.15 in accordance with the I=B=R Standard 

as published by the Hydronics Institute. The Net I=B=R Rating of 

the boiler selected should be greater than or equal to the calculated 

peak heating load (heat loss) for the building or area(s) served by the 

boiler and associated hot water heating systems. The manufacturer 

should be consulted before selecting a boiler for installations having 

unusual piping and pickup requirements.

in the state of massachusetts, boiler installation must conform 

to state code 248 cmr which includes but is not limited to:

This product must be installed by a licensed Plumber or 

•

Gas fitter.

When flexible connectors are used, the maximum length 

•

shall not exceed 36 inches.

When lever type gas shutoffs are used, they shall be T-

•

handle type.

For all side wall horizontally vented gas fueled equipment installed 

in every dwelling, building or structure used in whole or in part 

for residential purposes, including those owned or operated by the 

commonwealth and where the side wall exhaust vent termination is 

review the following before installing the boiler

This boiler product is a gas-fired, direct vent, condensing boiler and 

must be installed in accordance with all applicable federal, state and 

local building codes including, but not limited to the following:

United States

 - Installation shall conform with National Fuel Gas 

Code (NFPA-54/ANSI Z223.1- latest edition)

Canada

 - Installation shall be in accordance with CSA-B149.1 and 

.2 installation codes

.

Where required by the authority having jurisdiction, the installa-

tion must conform to the ASME Safety Code for Controls and Safety 

Devices for Automatically Fired Boilers, No.CSD-1.
The installation must conform to the requirements of the authority 

having jurisdiction or, in the absence of such requirements, to the 

National Fuel Gas Code, ANSI Z223.1 - latest revision.
