Series 24 Minimum Piping
Recommendations – Water Boiler
D
F
E
C
Impact of System Piping – Many hot water systems
are zoned. Some also use mixing valves to control the water
temperature in the system. These features can cause the
flow through the boiler to vary dramatically, depending on
the status of the zones or mixing valves. In addition, the
large water content of many commercial systems has the
potential to subject the boiler to operation with low return
temperatures for an extended period of time. These factors
can shorten the life of a boiler due to thermal shock or flue
gas condensation.
FRONT VIEW
BACK VIEW
■ The return temperature does not fall below 135°F
for an extended period of time.
RTC Return Temperature Control – Piping
Recommendation 3 makes use of CROWN’s optional
RTC (Return Temperature Control). This control provides an
economical and effective way of protecting the boiler from
thermal shock and condensation. It can be incorporated into
most hot water systems with minimal modifications to the
system design and operation. When this option is used on
multiple Series 24s, one RTC is required for each boiler.
The CROWN RTC is also available with an outdoor reset
option. This provides additional energy savings by
modulating system water temperature to match the
building load requirements.
Crown’s 3 Recommendations – On the following
pages, CROWN provides three basic recommendations
for near-boiler piping that are intended to maximize the
life expectancy of the boiler by protecting it from flue gas
condensation and thermal shock. Each protects the boiler
by making sure that both of the following conditions are met:
■ The flow through the boiler is high enough to
ensure a temperature rise of less than 40°F
Series 24 Minimum Piping Recommendations – Water Boiler

Recommendation 2 is a primary-secondary piping method
that maintains a constant flow through the boiler by using a
secondary boiler circulator. This arrangement isolates the
boiler from flow variations but does not safe-guard against
cold return water temperatures. Use when:

Notes:
1. Trim suffix
Fuel suffix
S = Steam Boiler
N = Natural Gas
W = Water Boiler
O = Oil
2. I=B=R net ratings shown are based on piping and pick-up allowances which vary from 1.333 to 1.289 for steam and 1.15 for water. Consult manufacturer for installations having unusual piping and pick-up
requirements, such as intermittent system operation, extensive piping systems, etc. The I=B=R burner capacity in GPH is based on oil having a heat value of 140,000 BTU per gallon.
3. Firebox volume does not include added volume of 8” extended burner mounting plate (BMP). If 8” BMP is specified (refer to Figure 1), add 0.7 cu. ft. to volume listed above.
4. Boiler ratings are based on 12.5% CO2 (oil) and 9.7% CO2 (natural gas), + .10” (inches) water column pressure at boiler flue outlet. Ratings shown above apply at altitudes up to 1000 feet on oil and 2,000
feet on gas. For altitudes above those indicated, the ratings should be reduced at the rate of 4% for each 1000 feet above sea level.
Maximum Allowable Working Pressure: Steam Boiler – 15 PSI, Water Boiler – 50 PSI
Standard Safety (Relief) Valve Set Pressure: Steam Boiler – 15 PSI, Water Boiler – 30 PSI
