To the New Owner:
Congratulations!
You are the owner of a state-of-the-art Gas Fireplace by REGENCY®. The HZ40E has been designed to provide
you with all the warmth and charm of a fireplace at the flick of a switch. The model HZ40E has been approved by
Warnock Hersey/Intertek for both safety and efficiency. As it also bears our own mark, it promises to provide you
with economy, comfort and security for many trouble free years to follow. Please take a moment now to acquaint
yourself with these instructions and the many features of your Regency® Fireplace.
On Demand Pilot Light (seven day safety timer)
Important information if using the appliance in CPI (continuous pilot mode) only.
This appliance is a ProFlame 1 system fitted with the “On Demand” Pilot, a safety feature which will shut down
the gas valve completely by extinguishing the pilot light in the event of a continuous full seven days of inactivity.
This only applies if the CPI (continuous pilot) switch is in the “on” position.
Each time the main burner shuts down, manually or through the call from the thermostat, the seven day
timer starts again.
The seven day inactivity timer is controlled within the circuit board. Therefore, if in CPI mode and when the
pilot light is extinguished after seven straight days of inactivity, the IPI/CPI rocker switch will remain in the “on”
position. Therefore, all that is required to relight the pilot would be to press the on/off button on the remote
control transmitter from “on” to “off” and back to “on”. Once the pilot has re-established operation will resume
as normal. There is no requirement to do anything with the IPI/CPI rocker switch.
If the unit never goes as long as seven full days without a call for heat, the pilot will remain lit until it is manu-
ally shut-off.
If the unit is being operated in IPI (intermittent pilot) mode, neither the above instructions nor the seven day
timer will apply.
See the instructions in this manual and on the Lighting Instructions plate on the appliance to light or re-light
the pilot.

Low Battery Power Detection Transmitter
The life span of the remote control batteries depends on various factors:
quality of the batteries used, the number of ignitions of the appliance,
the number of changes to the room thermostat set point, etc.
When the Transmitter batteries are low, a Battery Icon will appear on the
LCD display of the Transmitter (Fig. 22) before all battery power is lost.
When the batteries are replaced this Icon will disappear.
Figure 19
CPI/IPI Switch
This appliance comes equipped with a CPI/IPI switch.
The functions of both the CPI/IPI switch are as follows:
Continuous pilot (CPI) - A pilot that, once placed in operation, is intended to remain ignited
continuously until it is manually interrupted.
Intermittent pilot (IPI) - A pilot that is automatically ignited when an appliance is called on to
operate and which remains continuously ignited during each period of main burner operation. The
pilot is automatically extinguished when each main burner operating cycle is completed
The mode of the fireplace is easily changed from an intermittent pilot ignition system (IPI) to a
continuous pilot ignition system (CPI) by using the silver toggle switch located on the fireplace.
(See noted location of CPI/IPI Switch)
The benefits of having CPI are as follows:
-Keeps venting primed for trouble free start-up under colder weather conditions or inversions.
-Keeps the unit glass warm, which decreases the amount of condensation on start-up.
-Provides owners with flexibility to choose a traditional continuous pilot. (7 day/Pilot on Demand)
The primary benefit of having the IPI function is a significant savings on fuel as the pilot will only
run when there is a call for heat.
ENABLE / DISABLE functions on the Proflame I remote only.
1. Remove one battery from the remote.
2. Press and hold both the ON/OFF and the MODE button at the same time
3. Reinstall the battery (removed in Step 1) while still holding both buttons (keep holding both
buttons and once all batteries are installed then release the MODE button only).
4. The screen will show CFG.
5. Use the up or down arrow button to program out the function on the remote.
Note: You should never program out the fan (If installed) feature on the remote.
It is not possible to remove the thermostat mode on this remote control.
