When the vent system is disconnected for any reason it must
be reassembled and resealed according to vent
manufacturer’s instruction
11.4 CONDENSATE TREATMENT
Condensate occurs when the products of combustion are
cooled below their dew point in the heat transfer process.
The liquid condensate formed from this high efficiency heat
transfer process is mildly acidic.
• The condensate will typically have a pH ranging from
4.0 to 5.0 as it is discharged from the condensate drain
of the appliance.
• The condensate collection box inside each DynaMax
where the condensate is collected is constructed of a
non-corrosive plastic.
• All materials external to the appliance in contact with the
condensate must be corrosion resistant.
• Condensate must be able to flow freely from the
appliance. All condensate flow is accomplished by
gravity requiring a minimum downward slope of 1/4” per
foot (21mm/m) to ensure proper flow to a suitable drain.
• All condensate piping and connections must be easily
accessible for routine maintenance and inspection.
• Use solid piping when running condensate line across
the floor.
• Check neutralized pH level regularly or as required by
local jurisdiction. Replace neutralizer medium as
required.
There are several factors affecting amount of condensation
created by the appliance, however for rough approximation
use.
Condensation Volume, US Gallon/Hr = Input, MBH/1000 x
5.0
Many jurisdictions will require the acidic condensate to be
neutralized before it can be placed in a drain system.
• A neutralizer, calcium carbonate, to control the pH of the
liquid discharged to a drain system is provided with
every DynaMax boiler.
• Neutralizer consists of an industrial grade, non-corrosive
plastic reservoir for collection of the condensate.
• As the reservoir fills, it provides an extended residence
time to neutralize the condensate.
• Residency time in the neutralizer reservoir allows time
for the pH to be raised.
• Prime the neutralizer reservoir with 1 liter of water.
As the condensate migrates through the reservoir in typical
applications the pH is controlled to a range of 5.5 to 6.0
before exiting the system. Always check with local codes for
specific requirements.
11.5 IGNITER AND FLAME SENSOR
ELECTRODES
The direct spark igniter is to be checked at every service
interval. Clean the direct spark igniter as required to maintain
peak ignition efficiency.
1) Turn off main electrical power to the appliance.
2) Turn off main manual gas shutoff to the appliance.
3) Locate the direct spark igniter and flame sensor.
4) Disconnect the power lead to the direct spark
igniter and flame sensor
5) Loosen and remove the two (2) torx screws that
hold the igniter and flame sensor to the heat
exchanger flange.
6) Pull the igniter horizontally out of the heat
exchanger flange. Use care, do not hit or break the
igniter leads.
7) Remove any debris that has accumulated on the
electrodes using steel wool. If the electrodes cannot
be cleaned to their original appearance,
replacements are needed. Do not use sand-paper
since this will contaminate the surface.
8) Check that the igniter and flame sensor gaskets are
still in good condition (no tears or seams). If the
gaskets are in good condition the electrodes can be
re-installed back to the heat exchanger flange.
9) Check that the igniter gap is 9/64”.
11.6 CHECK IGNITER GROUND WIRING
1) Inspect boiler ground wire from the heat exchanger
flange to J12 of the electrical DynaMax Controller.
Check boiler ground wire continuity.
2) Verify that all wiring is in good condition and is
securely anchored.
11.7 BURNER MAINTENANCE
The burner should be removed for inspection and cleaning
on an annual basis. An appliance installed in a dust or dirt
contaminated environment will require inspection and
cleaning on a more frequent schedule. The fan assisted
combustion process may force airborne dust and dirt
contaminants, contained in the combustion air, into the
burner. With sustained operation, non-combustible
contaminants may reduce burner port area, reduce burner
input or cause non-warrantable damage to the burner. Never
operate this appliance during construction.
Airborne contaminants such as dust, dirt, concrete dust or
dry wall dust can be drawn into the burner with the
combustion air and block the burner port area.
11.7.1 Burner Removal and Cleaning
Access to the burner will require the following steps:
• Turn off main electrical power to the appliance.
• Turn off main manual gas shutoff to the appliance
• Remove the front cover.
• Disconnect the gas supply connection to the fan
inlet.
• Disconnect the fan motor power wires at the
harness.
