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.
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.

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.
