Glycol % Setting

The XFiire product is equipped with algorithms that will

ensure optimum operation when using different glycol

concentrations as the heat media. From the VERSA IC

touchscreen, the user must select a glycol concentration.

This setting can be found within the Adjust Menu within

System Settings.

NOTE:

The factory default value is 50% glycol

concentration. Restoring factory defaults WILL NOT

reset this value.

When replacing the VERSA IC, it is important to update

the glycol percentage value as needed for proper system

operation.
The glycol protection will reduce the maximum firing rate,

but will also change the entire heating profile depending on

the model size. See

Figure 44

Figure 44. Glycol Operation Chart

Vent Protection

The XFiire heaters are equipped with a vent temperature

sensor located at the rear of the heater. See

Figure 4.

The vent protection algorithm will anticipate a flue

temperature overshoot and adjust the firing rate of the

heater to prevent excessive flue temperatures from

occurring.

NOTE:

The factory default is set to “PVC”.

During commissioning of the heater, the vent material

must be selected in the Adjust Menu (Submenu of System

Settings) to indicate the vent material installed on the

heater.
The settings for the Vent Protection include:

NOTE:

Use only certified vent material ANSI/ASTM

D1785 Sch 40 PVC, ANSI ASTM F441 Sch 40 CPVC.

• Vent Material.

PVC (149°F/65°C),

CPVC (194°F/90°C),

PPS (Polypropylene) (230°F/110°C),

Stainless Steel (AL29-4C)

• Vent Differential.

Subtractive value from max vent

temperature that defines when the control will take

action to prevent unit from reaching the max vent

temperature. Default 10°F (5.6°C) selectable from

1°F (0.6°C) - 20°F (11°C).

• Vent Rate.

This value defines the max firing rate

the heater will be allowed to operate at when Vent

Protection is active.

If the vent temperature exceeds the allowable limit for

the vent material selected, the burner will cycle. This

is an automatic reset function and as soon as the vent

temperature drops to an acceptable level, the heater will

return to normal operation.

NOTE:

The use of PVC/CPVC will require the user to

limit the maximum setpoint of the heater in the Adjust

menu.
