Condensate Drain Connection
This is a condensing high efficiency appliance, and therefore has a condensate removal system. Condensate is nothing more than
water vapor derived from combustion products. The condensate is similar to that of an automobile when it is initially started.
It is very important that the condensate line slopes away from the appliance, down to a suitable drain. If the condensate outlet is lower
than the drain, you must use a condensate removal pump (kit 554200, available from HTP).
A condensate filter, if required by local authorities, can be made up of lime crystals, marble or phosphate chips, and will neutralize the
condensate. This can be purchased from HTP (7450P-212) and installed in the field.
It is also very important that the condensate line is not exposed to freezing temperatures or any other type of blockage. Plastic pipe
must be the only material used for condensate line. Steel, brass, copper, or other materials will be subject to corrosion or deterioration.
A second vent may be necessary to prevent a condensate line vacuum lock in a long, horizontal line. Also, an increase in pipe size may
be necessary to drain properly. Support of the condensation line may be needed to avoid blockage of flow.
Spark Ignition
The burner flame ignites by applying high voltage to the system spark electrode. This causes a spark from electrode to ground.
Outdoor Sensor
The outdoor sensor allows the installer to make the appliance even more efficient by basing temperature delivered to the central
heating circuits on outdoor temperature. (See Optional Equipment, Section C).
(Optional) Indirect Tank Sensor
– Indirect Priority
To control the temperature of low temperature heating circuits when using an indirect fired water appliance, a thermostatic mixing valve
is required. Failure to install a thermostatic mixing valve could result in property damage.
The indirect sensor allows the installer to operate the appliance with two temperatures: one for central heating and the other for the
SuperStor Indirect Water Appliance. This allows the user to increase water temperature supplied to the indirect to get faster recovery by
prioritizing flow at a higher rate than may be needed for central heating. NOTE: This application requires two separate circulators. (See
Optional Equipment, Section C).
VERSA-FLAME DHW MODULE
The Versa-Flame combines all of the capabilities of the Pioneer with an integrated domestic hot water (DHW) module built into the
appliance. Features include:
Brazed Plate Heat Exchanger
When the system calls for DHW, hot heat transfer fluid is drawn from the top of the appliance through the brazed plate heat exchanger.
The heat exchanger consists of a series of thin corrugated plates brazed together in counter flow channels of alternating hot and cold
fluids. This counter flow system provides optimal heat transfer to the DHW system.
Circulation Pump
Draws hot heat transfer fluid from the top of the appliance through the brazed plate heat exchanger and returns the cooler heat transfer
fluid to the bottom of the appliance.
Flow Switch
Senses flow into the brazed plate heat exchanger and turns on the pump when flow is greater than .5 gpm. The flow switch will shut
down the pump when flow is less than .5 gpm.
Thermostatic Mixing Valve
Accurately controls the temperature of DHW by mixing cold water with the hot water leaving the heat exchanger. The installer can
adjust DHW temperature by manually adjusting the valve.
