These low pressure gas-fi red hot water boilers are design
certifi ed 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 accordance with
A.S.M.E. (American Society of Mechanical Engineers) Boiler
and Pressure Vessel Code, Section IV Standards for heating
boilers.
Boilers are certifi ed in accordance with ANSI (American
National Standards Institute) Z21.13 standards as gas-
fi red, direct vent, condensing, hot water boilers.
Complete the following prior to installing boiler.
Codes

authority having jurisdiction or, in the absence of such
requirements:
•
United States
- National Fuel Gas Code, NFPA 54/
ANSI Z223.1
•
Canada
- Natural Gas Propane Installation Code,

Heating Capacity indicates amount of heat available
after subtracting losses up the stack. Most of this heat is
available to heat water. Small portion is heat loss from
jacket and surfaces of boiler, it is assumed this heat stays
in the structure. Net I=B=R Rating represents portion
of remaining heat applied to heat radiation or terminal
units (i.e. Finned tube baseboard, cast iron radiators,
radiant fl oor, etc.). Difference between Heating Capacity
and Net I=B=R Rating, called piping and pickup allowance,
establishes reserve for heating volume of water in the
system and offsetting heat losses from piping. Net I=B=R
Ratings shown are based on piping and pickup factor of
1.15. Net I=B=R Rating of boiler selected should be greater
than or equal to calculated peak heating load (heat loss)
for building or area(s) served by boiler and associated hot
water heating systems. Manufacturer should be consulted
before selecting boiler for installations having unusual
piping and pickup requirements
Where required by the authority having jurisdiction,
installation must conform to the Standard for Controls and
Safety Devices for Automatically Fired Boilers, ANSI/ASME
CSD-1
