Hyd.o'lfcsLtd. Models DR(H) 0300 — DR(H) 5000 CITY OFTIGARD
BUILDING DIVISION
The heating boiler shall be a CAMUS DYNAFORCE model having an input rating of Btu (kW) /hr. and
Btu (kW)/hr output for hydronic heating.
The hydronic heating boiler shall. be design certified by CSA International and shall meet the requirements of ANSI Z21.13, and CSA
4.9. The heating boiler shall be vented as a Category II or IV condensing appliance.
Performance Overview:
- Boiler shall operate up to 99% thermal efficiency
- Heat exchanger shall be a fully condensing primary - secondary cylindrical counter -flow water tube design with 439 grade
stainless steel construction and all welded design with constant allowable system return temperatures of 40F.
- Fine tuned combustion premix providing homogeneous air and gas combustion mix to a radial burner incorporating a knitted
stainless steel wrap ensuring stable light off and efficient clean combustion.
- 5:1 gas input turn down ratio with sustained efficient combustion characteristics throughout entire modulating range
- Oxides of Nitrogen (NOx) of 9 ppm corrected to 3% oxygen.
- Category II venting certification with Category II and IV venting options.
- The boiler is fully factory fire tested to obtain optimum combustion characteristics and to establish certified gas input rates.
- System safety and operating devices and controls are fully configured, calibrated and factory tested.
- Models consist of an input range of 300 MBTUH to 5000 MBTUH
Combustion Chamber:
The combustion chamber shall be an all welded stainless steel construction and an integral part of the heat exchanger which shall be
an all welded vertical cylindrical stainless steel counter -flow design consisting of an upper bumer section for primary heat transfer and a
lower section for extracting latent heat from flue gases. Stainless steel access heat exchanger wraps shall be provided for ease of
service and inspection of the external heat exchanger and an easily removable radial fired knitted fiber stainless steel burner to access
the intemal combustion chamber for inspection, service, and cleaning. A window view port shall be provided for visual inspection of the
boiler combustion during firing.
Heat Exchanger:
The stainless steel heat exchanger shall be inspected and tested to A.S.M.E. Section IV requirements. The A.S.M.E. Section IV seal of
approval will not be provided as standard for jurisdictions not requiring the A.S.M.E Section IV seal of approval. The stainless steel heat
exchanger shall be a 12 pass primary secondary design with a maximum working pressure of 160 psig (1100 kPa). The heat exchanger
shall be of 439 grade stainless steel welded construction with a vertical cylindrical counter -flow water tube design complete with integral
439 grade stainless steel finned heat transfer tubes and waterways. The heat exchanger design shall be capable of 40 ° F constant
system retum temperatures and have a fully condensing primary and secondary heat exchanger complete with condensate trap and
drains. A pressure relief of valve of lb/hr shall be fumished with the heater.
Gas Train:
The gas train shall consist of a pressure regulating electro-hydraulic proportional air /gas main gas actuator providing a slow opening,
fast closing shutoff valve and proportional 1:1 air /gas ratio control, a fast closing safety shutoff gas pressure regulator with 1 PSI
allowable static pressure, and a low gas pressure switch. Optional high gas pressure switch is available. A factory pre -set combination
metering valve and orifice shall be provided for setting combustion parameters. Models DR 300 — DR 5000 operate with a 5:1 turndown
ratio.
Burner /Combustion:
The combustion air fan draws gas under negative pressure and mixes it with air to generate a fine tuned air gas mixture which is
delivered under positive pressure to the radial knitted stainless steel burner. Combustion modulation is established by either a pulse
width modulation signal on models (DR300 — DR800) or by a variable frequency drive on models (DR1000 — DR5000). The bumer shall
be a 100% stainless steel vertical mounted radial fired type with stainless knitted metal fiber construction. The bumer shall combust a
precise amount of premixed combustion air and gas to provide equal distribution of heat for heat transfer throughout the entire heat
exchanger. Combustion products are exhausted under minimum back pressure. Combustion operates with a 5:1 turn down ratio while
sustaining combustion characteristics throughout the entire modulating range. Operation of up to 99% thermal efficiency and shall be
certified for Oxides of Nitrogen (NOx) of 9 ppm corrected to 3% oxygen.
Firing Mode:
The burner combustion shall operate as proportional modulating with a 5:1 tumdown ratio with a minimum 20% firing rate. Multiple
boiler "Cascade" firing algorithms are proportional modulation. Light off shall be at no more than 50% input to assure rumble free soft
start. Combustion shall be optionally suitable for natural gas, propane and dual fuels operation.

Controls:
Standard controls include a SOLA electronic proportional integrated combination ignition limit/operator control accurate to 1 ° F (0.5 ° C)
having a 4 -20 mA output signal suitable for control of a variable frequency motor drive or a pulse width modulation signal output for
modulating fan speeds. Controls are lead lag "Cascade" ready for control of up to eight boilers c/w Indoor outdoor reset and lead lag
control. Control shall be equipped and ready with 4 -20 mA remote set point or modulating control, capable with 0 -10 VDC remote set
point and modulating control. Control is BMS Modbus RTU protocol ready and capable of other altemate protocol conversions with
additional optional gateway protocol converter. Control shall be supplied with a mounted touch screen mid level display which shall also
provide for control system configuration and set up, readouts of boiler target, differential and inlet/outlet temperatures as well as
accumulated runtime, enunciator diagnostics, and firing rates. Optional "System" control display shall provide full diagnostics including
real time data logging and support for up to eight (8) boilers in "Cascade" sequencing application, MODBUS ready. The complete
control package shall be mounted on the front panel with a hinged door for easy access to all control modules. The boiler safety control
string shall be fumished with controls for low gas pressure, optional high gas pressure, fan air proving, blocked flue, water pressure,
high limit, stack limit and flow switch. A flow switch shall be provided loose. Additional control safeties shall include flue gas stack
