The ABSOLUTE “ABS SERIES” of hydronic heating condensing boilers is a combination of more than 35
years of North American and European engineering experience in condensing boiler technology.
The ABSOLUTE “ABS SERIES” utilizes a durable sectional cast aluminum heat exchanger engineered and
designed in Europe. The cast aluminum provides a robust corrosion resistant heat exchanger that allows for
ultra-high eciencies with the added benet of a small, light weight boiler foot print. The ABSOLUTE “ABS
SERIES” heat exchanger also provides additional eciencies with large water ways, reducing the pressure
drop through the boiler! We are so condent in our heat exchanger, we provide an industry leading warranty.
The fully water cooled combustion chamber host a knitted metal ber premix burner. A turndown ratio of
10:1 allows for ultimate combustion control and reduces short cycling of the boiler. With precise combustion
control the ABSOLUTE “ABS SERIES” is able to achieve CO2 levels that maximize condensation of the
natural gas. Low NOxand CO emissions are the standard with the ABSOLUTE “ABS SERIES”.
The ABSOLUTE “ABS SERIES” incorporated the Honeywell Sola boiler control system for ultimate boiler
control. The Sola allows for quick and easy set-up of the ABSOLUTE “ABS SERIES” of condensing boilers.
The user friendly touchscreen control ensures simplied monitoring and diagnostics along with: multiple boiler
conguration (eight boilers), remote monitoring, fault history, trend analysis, boiler status, communicates
via 3-wire RS-485 ModBus™ protocol, DHW priority.

The standard control package allows for external On/O, local-remote switch. The built in digital display shows normal
operating fault indications and allows actual and set values to be read and adjusted.
The intelligent, advanced boiler control continuously monitors the boiler operating conditions, varying the heat output to
suit the system load. The control is able to react to external “negative” inuences in the rest of the system (ow rates,
air/gas supply problems) maintaining boiler output for as long as possible without resorting to a lock out condition. At
worst the boiler will reduce its output and/or shut down (shut o mode) awaiting the “negative” conditions to return
to normal before re-starting.
- The Sola controller has 4-20 MA, RS-485 Mod-Bus interface
- The Honeywell and the Sola controls cannot override the standard ame safety controls. External controls or
commands can modulate the boiler as required by the BMS.
- All Absolute boilers are fully test red after assembly to ensure the boiler and controls comply with our strict quality
policy.
- The packaged boiler is constructed and approved according to the following standards:
- ANSI Z21.13 / CSA 4.9 - 2014
- UL 795
- CGA CAN1-3.1
- ASME Section IV
- CRN for each Canadian Province ( where applicable )
- Electrical according CSA 22.2 No 0.M91 & NEC/NFPA 70
- Gas Vent Category II & IV
- Consult factory for other certications or qualications.
- CSD-1 compliant

2.2 Operational principal of boiler
Combustion air is drawn into the inlet connection from the plant room (room ventilated version) or from outside via the
air inlet pipe.
On the inlet side of the fan is a specially designed chamber which takes gas from the multi-block and mixes it in the
correct proportions with the incoming air. This mixing system ensures that the correct gas/air ratio is delivered to the
pre-mix burner at all times.
Depending on demand (under the dictates of ow/return sensor and other external/internal control inputs) The Honeywell
Sola Control varies the speed of the air supply fan which alters the volume of air/gas mixture that is delivered to the
combustion chamber. The resultant controlled mixture is delivered to the premix burner.
This mixture is initially ignited by the combined ignition/ionization probe which monitors the state of the ame. Should
the ame be unstable or not ignite within the pre-set safety time cycle the controls will (after 3 attempts) shut the
boiler down requiring manual intervention to reset the boiler. The display will indicate a ashing fault code 3 times
conrming the reason for the failure.
The products of combustion in the form of hot ue gases are forced through the heat exchanger transferring their heat
to the system water, (the ue gas temperature is reduced to approximately 9-14° F [5-8° C] above the temperature of
the system return water) then discharged via the condensate collector, to the ue gas outlet connection, to atmosphere.
Because of the low ue gas exit temperature there will be a vapor cloud formed at the ue gas terminal – this is not
smoke, simply water vapor formed during the combustion process.
If the ue gas temperature falls below the dew point of 131°F [55°C], water vapor (created during the combustion
process) will begin to condense in the boiler, transferring its latent heat into the system water, thereby increasing the
output of the boiler with-out increasing the gas consumption. Condensation formed within the boiler and ue system
is discharged from the boiler to an external drain via the drain pan and siphon supplied.

is in your own interest and that of safety to ensure that the local law is complied with. The following codes must be
adhered to when the Absolute Boiler is installed:
-CSA B149 gas installation code & ANSI Z223.1 / NFPA 54 gas code.
In addition to the above regulations, this boiler must be installed in compliance with:
- National & local building codes
- ASME CSD-1 as required
- CSA & NEC electrical codes
- Other Regulations
WARNING
All Absolute boilers are CSA certied, and must not be modied or installed in any way contrary to these “Installation
and operations manual.
4.2 Delivery and installation
The Absolute boiler is supplied fully assembled, plastic wrapped and crated on a pallet. The Unit should be completely
inspected for evidence of shipping damage and shipping completeness at time of receipt. From the carrier and BEFORE
the bill of ladling is signed. The carrier MUST be notied immediately if any damage is detected.
The overall dimensions of the crate are 36 inches [92cm] wide, 70 inches [178 cm] high with the length of 50 1/8
(127 cm). At the base of the packaging is a 30” [76 cm] wide pallet enabling it to be transported with a pallet truck,
forklift truck or 4-wheel transport boards. Excluding the crate, the boiler is 22 1/16 [56 cm] wide complete with casing
panels, the boiler will t through most standard doors (minimum door opening width 34.5” [87 cm]. The boiler itself
has 2 wheels so that, once the packaging has been removed, it can easily be moved around on a smooth surface. The
packaging lid includes a rocking ramp, which can be used to negotiate obstacles such as doorsteps and small plinths.
Once in position the boiler is xed into position using the tted jacking bolts which both raise the wheels of the ground
and level the boiler. Technical documentation is supplied in a holder on the inside of the boiler casing (beneath the
instrument panel). A number of small loose components, such as the 4 support pads, siphon, and relief valve, for the
boiler have been placed in a box marked accessories near the ue gas discharge
