Are they really Equal?

It can be a little grey if you don’t have all the information.
RBI has worked hard to develop a worry free INDUSTRIAL
boiler design. Are you’re equals truly keeping up?

Condensing “Package”:
The boiler shall be completely packaged and
tested as a package by the factory. Boiler shall
have the boiler ‘package’ listed and tested as per
UL/CSA and ASME section IV standards. Each
boiler shall be fire-tested as a package in the
factory prior to shipment. Test report shall show
all combustion settings at various points of
modulation, as well as corresponding delta T. A
single primary pump shall be supplied, sized,
piped and wired within the manufacturers control
sequence by the manufacturer. A three way
tempering valve shall be piped and wired to allow
for return temperatures as low as 40F directly to
a single water inlet.
The use of independent secondary heat
exchangers and/or economizers will not be

Does this sound
like a true

Non-condensing
can return 115F
but condensing
130F?????

Step one: Read the manual!
Absolutely untrue.
We represent Cat.

that have NO
minimum and
some that have a
60F limit. It’s
about design, not
‘official’ listing!

Step one: Read the manual!
So, they give us the
CHRM separate and ‘we’
have to protect it (flow
and temp), shed the load
with it, monitor
temperatures and be
responsible for any
misapplication?
Again, not a ‘packaged’
condensing boiler!
CONSTRUCTION & DESIGN – Dynaflame Camus
Step one: Read the manual!
Finally, a drawing! Of
course, this is typical..
Since you have to
design and pipe it, I
guess you can do it
however you want.
Bottom line is, you need
to pipe both HX, and
control the primary
temperature. If you
don’t.. Warranty is void!

Experience Knows Better!
CONSTRUCTION & DESIGN – Dynaflame Camus
Step one: Read the manual!
Secondary HX in vent. add the flow
switch, valves, and a second pump. Be
sure to get the GPM from this HX and
size the pump for it. Also add temp
controls and sequencing.
Below 140F, you better use a
three way bypass system. Of
course you need to design it
and have it installed.
Primary HX separate. Don’t forget
140F, 130F, 120F, or 115F… not sure
which they really want but it’s up to
you to keep it warm! Oh, and another
primary pump!

Well, there will be a realization
that all the equal products are
far more expensive. Camus
then had a ‘cap’ to bid up to.

On the ‘outside’ the contractor seemed to have saved $6,700.00. Had he
not used this price on bid day, he could have lost the project. That’s only
$3,350.00 per boiler.
Problem is, the END USER sacraficed $5,079.00 per boiler in equipment,
trim and features or a total of $10,158.00 over all. Was the investment
wise?
Additionally, chances are the contractor was not aware he had additional
cost in piping, pumping, design work, trim and safety controls. That
closes the gap very quickly.
If the contractor didn’t know it, as an engineer you must know it because
these items can easily slip by the submittal if you are not careful. The
end user actually suffers from the very competition we think is healthy!

The ‘real’ Equals
“The basis of design shall be the RBI Fusion series packaged condensing boiler.
Sizes, quantities and capacities as listed on the drawings.
Acceptable equal manufacturers shall still meet the performance and intent of this
specification completely. Installation must completed in accordance to the
requirements of the manufacturer.
Any additional cost incurred by using one of the following approved
manufacturers shall be that of the installing contractor. This includes, but is not
limited to venting, piping, electrical, and/or any needed as built drawings.
In accordance with the above, you may provide a product equal to the
requirements of this specification as manufactured by:”
A: Aerco Benchmark
B: Lochinvar Intellifin
C: Laars Rihos

The ‘real’ Equals
Allowing the Camus Dynaflame to be an acceptable equal to
a packaged condensing boiler opens the door for the
following:
•Any copper boiler manufacturer should be permitted to
provide his ‘base’ boiler design with a separately shipped
stack economizer.
•Base boilers should be allowed a light commercial
residential flame safeguard and ignition system.
•Any form of boiler controls become acceptable because of
the limitations of this equal product.
