NOTICE
Handling ceramic fiber materials
REMOVAL OF COMBUSTION CHAMBER LINING
WARNING
The combustion chamber insulation in this appliance contains ceramic fiber material. Ceramic fibers can
be converted to cristobalite in very high temperature applications. The International Agency for Research
on Cancer (IARC) has concluded, “Crystalline silica in the form of quartz or cristobalite from occupational
sources is carcinogenic to humans (Group 1).” Normal operating temperatures in this appliance are below
the level to convert ceramic fibers to cristobalite. Abnormal operating conditions would have to be created
to convert the ceramic fibers in this appliance to cristobalite.
When calling or writing about the boiler
– Please have the boiler model and serial
number from the boiler rating plate.
Consider piping and installation when
determining boiler location (see the Crest
Installation and Operation Manual).
Any claims for damage or shortage in
shipment must be filed immediately
against the transportation company by the
consignee.
The ceramic fiber material used in this appliance is an irritant; when handling or replacing the ceramic
materials it is advisable that the installer follow these safety guidelines.
Avoid breathing dust and contact with skin and eyes.
• Use NIOSH certified dust respirator (N95). This type of respirator is based on the OSHA
requirements for cristobalite at the time this document was written. Other types of respirators may
be needed depending on the job site conditions. Current NIOSH recommendations can be found on
the NIOSH website at http://www.cdc.gov/niosh/homepage.html. NIOSH approved respirators,
manufacturers, and phone numbers are also listed on this website.
• Wear long-sleeved, loose fitting clothing, gloves, and eye protection.
Apply enough water to the combustion chamber lining to prevent airborne dust.
Remove the combustion chamber lining from the appliance and place it in a plastic bag for disposal.
Wash potentially contaminated clothes separately from other clothing. Rinse clothes washer
thoroughly.
NIOSH stated First Aid.
Eye: Irrigate immediately.
Breathing: Fresh air.

Please read before proceeding
When servicing boiler –
• To avoid electric shock, disconnect electrical supply
before performing maintenance.
• To avoid severe burns, allow boiler to cool before
performing maintenance.
Boiler operation –
• Do not block flow of combustion or ventilation air to
the boiler.
• Should overheating occur or gas supply fail to shut off,
do not turn off or disconnect electrical supply to
circulator. Instead, shut off the gas supply at a location
external to the appliance.
• Do not use this boiler if any part has been under water.
The possible damage to a flooded appliance can be
extensive and present numerous safety hazards. Any
appliance that has been under water must be replaced.
Service Manual
Boiler water –
• Thoroughly flush the system (without boiler
connected) to remove sediment. The high-efficiency
heat exchanger can be damaged by build-up or
corrosion due to sediment.
• Do not use petroleum-based cleaning or sealing
compounds in the boiler system. Gaskets and seals in
the system may be damaged. This can result in
substantial property damage.
• Do not use “homemade cures” or “boiler patent
medicines”. Serious damage to the boiler, personnel,
and/or property may result.
• Continual fresh make-up water will reduce boiler life.
Mineral buildup in the heat exchanger reduces heat
transfer, overheats the stainless steel heat exchanger, and
causes failure. Addition of oxygen carried in by makeup
water can cause internal corrosion. Leaks in boiler
piping must be repaired at once to prevent the
introduction of makeup water.
Freeze protection fluids –
• NEVER use automotive antifreeze. Use only inhibited
propylene glycol solutions which are specifically
formulated for hydronic systems. Ethylene glycol is
toxic and can attack gaskets and seals used in hydronic
systems.

General Operation
Service Manual
How the boiler operates
The Crest uses an advanced stainless steel heat exchanger
and electronic control module that allows fully condensing
operation. The blowers pull in air and push flue products out
of the boiler through the heat exchanger and flue piping. The
control module regulates blower speeds to control the boiler
firing rate. The gas valves sense the amount of air flowing into
the boiler and allow only the right amount of gas to flow.
How the control modules operate
The Crest boiler is equipped with a SMART TOUCH
CON•X•US Interface. The control module receives inputs
from boiler sensors and external devices. The control module
activates and controls the blowers and gas valves to regulate
heat input and switches the boiler, Hot Water Generator
(HW), and system pumps on and off as needed. The user
programs the control module to meet system needs by adjusting
control parameters through the SMART TOUCH CON•X•US
Interface. These parameters set operating temperatures and
boiler operating modes.
Sequence of operation
Table 1A (page 11) shows control module normal
sequences of operation for space heating and HW
operation. The combined operation sequence is for a
typical application, programmed to provide HW priority.
Access modes
User
The USER can set the SH set point, HW set point, turn the
unit OFF and ON and set up WiFi.
Installer
Most parameters are available only to the INSTALLER,
accessible only by entering the installer password (5309)
when selecting the Setup Section.
Note: The password will timeout after an hour from
entry.

Table 1A Sequence of Operation
Sequence of operation
Note: This unit is equipped with two (2) gas train systems. Gas Train 1 will fire first. If the demand cannot be met by the first
gas train, the second gas train (Gas Train 2) will fire.
Upon a call for heat, the control turns on the appropriate pumps (system and boiler pumps for a space heating call,
1.
HW pump for a hot water generator call).
The control confirms that the low water cutoff contacts are closed and energizes the louvers (optional) and damper
2.
(optional) relays.
The control confirms that the gas pressure switch, blocked drain switch, limits, louver proving switch (optional) and
3.
damper proving switch (optional) contacts close. The Pre-Purge cycle begins.
The control confirms the blower is up to the desired speed, and the air pressure switch is closed.

5.
6.
7.
8.
9.
10.
11.
Once the Pre-Purge cycle is complete, the control lowers the blower speed, closes the air metering valve, initiates
sparking of the ignition electrode, and opens gas valve 1.
After a short wait, the control stops sparking and checks for the presence of flame current through the flame sense
electrodes.
If flame is not detected after the sparking ends, the control will perform a postpurge, then start another prepurge cycle
and try to light the burner again.
If the control detects flame current, the control will hold the blower speed constant for a few seconds to allow the
flame to stabilize, then begin modulating the firing rate in order to maintain the controlling sensor to the desired set
point temperature.
If the current call for heat is for space heating and a HW call for heat becomes active, the control will turn on the HW
pump relay output, then turn off the boiler pump. It will then modulate the blower speed in order to maintain the
outlet temperature to the desired HW outlet set point temperature (Normal Mode Only).
If the boiler is unable to maintain the desired set point using gas valve 1, control will transition to the larger gas valve
2. The blower will modulate to a fixed speed and the air metering valve will start to open. As it opens, gas valve 2 will
be turned on and gas valve 1 will be turned off. If the flame should be lost at any time during this process, the control
will immediately try to reignite the burner. Once the air metering valve is fully open and the flame is confirmed to
be present, the control will hold the fan speed constant for a few seconds in order to allow the flame to stabilize. The
fan speed will then modulate as needed to maintain the set point. If the flame is not present when the air metering
valve is fully open, the boiler will go through a complete shutdown and restart of the burner. If the heat load should
decrease sufficiently, a similar process is used to transition from gas valve 2 to gas valve 1.
Once both the space heating and HW calls for heat are satisfied, the control will turn off the gas valve and begin the
Post-Purge cycle. Any pumps that are running will begin their respective Pump Delay cycles. The air metering valve
will be opened.
12.
13.
At the end of the Post-Purge cycle, the louver relay contacts will de-energize.
At the end of the Pump Delay cycle(s), the pump(s) will be turned off.

Set Points
Space Heat 1 Set Point: Set point
The SH set point sets the water temperature set point used
during space heating calls.
Space Heat 1 Set Point: Min
The SH minimum set point sets the minimum water
temperature set point that can be used for space heating
operation. The user or installer will not be able to
program the control with a lower SH set point.
Space Heat 1 Set Point: Max
The SH maximum set point sets the maximum water
temperature set point that can be used for space heating.
The user or installer will not be able to program the
control with a higher SH set point.
Space Heat 1 Set Point: Offset
The SH offset sets how many degrees above set point the
temperature can go before the boiler will shut off.
Space Heat 1 Set Point: Differential
The SH differential sets how many degrees below the
offset the temperature has to drop before the boiler turns
back on.
High Limit: ARHL
The SMART TOUCH control contains an integral Auto
Reset High Limit (ARHL) on the outlet of the heat
exchanger. Once the outlet temperature exceeds the
ARHL set point, the boiler will shut down and lock out.
Once the outlet temperature has dropped below this
set point, the RESET button on the LCD display can be
pressed to reset this lockout. If RESET is not pressed, the
control will automatically reset the lockout after five (5)
minutes.
HW Boiler Set Point: Set point
When a HW call for heat becomes active, the control will use
the HW boiler set point to determine the firing rate of the
boiler based on the boiler outlet water temperature.
HW Boiler Set Point: Offset
This parameter reflects the degrees above HW boiler set point
the outlet temperature can go before the boiler will shut off.
HW Boiler Set Point: Differential
This parameter reflects the degrees below HW boiler offset the
outlet temperature has to go before the boiler turns on.
HW Tank Set Point: Set Point
By installing a tank sensor, the SMART TOUCH control can
perform the tank thermostat function. The SMART TOUCH
control automatically detects the presence of this sensor, and
generates a call for heat when the tank temperature drops
below the tank set point minus the differential, and finishes the
call for heat when the tank temperature reaches tank set point.
HW Tank Set Point: Min
This setting controls the minimum user set point for the tank
temperature.
HW Tank Set Point: Max
This setting controls the maximum user set point for the tank
temperature.
HW Tank Set Point: Differential
When a tank sensor is installed, the tank temperature must
drop this amount below the tank set point before the boiler
will turn on.
High Limit: MRHL
The SMART TOUCH control contains an integral
Manual Reset High Limit (MRHL) on the outlet of the
heat exchanger. Once the outlet temperature exceeds
the MRHL set point, the boiler will shut down and lock
out. Once the outlet temperature has dropped below this
set point, the RESET button on the LCD display must be
pressed to clear this lockout.

Outdoor Reset Curve
The Outdoor Temp Min and Set Point Max define the
upper point of the Outdoor Reset Curve. The lower point
is defined by the Outdoor Temp Max and Set Point Min.
The curve will level out at Set Point Min for temperature
warmer than Outdoor Temp Max. The curve will continue
on if the set point (set on Set Points Screen) is above the Set
Point Max. The curve will be shortened if the set point is
below Set Point Max.
Outdoor Temperature: Shutdown
When the outdoor temperature rises above this point, the
control will block all SH demands (HW demands will still
be active).
Outdoor Temperature: Differential
The outdoor air shutdown differential parameter is the
number of degrees below parameter the outdoor air
temperature must go before the boiler will respond to a SH
demand.
Boost Temperature
If a SH demand lasts longer than the programmed boost time
delay setting and there have been no HW demands, the control
will increase the water temperature set point by the amount in
this parameter. If the SH demand continues through another
time period, the set point will be increased again. This will
continue until either the SH demand ends, a maximum of 20
increases has occurred, or the maximum set point has been
reached. Once the SH demand has been satisfied the set point
will revert back to its calculated setting.
Shift OA Reset Curve
The shift reset curve parameter shifts the actual set point
above or below the calculated set point by the number of
degrees in this parameter.
Boost Time
The boost time parameter sets the amount of time that must
elapse with a SH demand before the water temperature
calculated set point will be increased.
