Display Backlight
The display panel back light will automatically turn off five seconds
after an input (either manual or remote) is acknowledged. The
back light will automatically turn on when a new input is acknowl-
edged. To turn the back light on manually, press the "Display Back-
light" button on the bottom left of the display panel (Figure 40).
Shut Down Instructions
To turn the fireplace off, simply push "OFF" on the remote or push
the display panel's mode select button to "OFF". See Figure 40.
DO NOT cut the main electrical power to the fireplace.
The circulating blower will continue to operate after the burner is
turned off. The blower will stop automatically once the fireplace
has cooled down.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5 in. w.c. at the valve outlet, with the
inlet pressure to the valve at 5.0 in. w.c. to 10.5 in. w.c. Propane
gas models will have a manifold pressure approximately 7.0 in.
w.c. at the valve outlet, with the inlet pressure to the valve from
11.0 in. w.c. to 13.0 in. w.c.
A pressure tap accessible for test gauge connection, is located on
the outlet side of the gas control.
Blower Operation
The circulating air blower will automatically engage and increase
in speed depending on the operation of the burner. In most circum-
stances, the circulating blower will start three to five minutes after
ignition of the burner.
Once the fireplace is turned off or the call for heat has been sat-
isfied, the circulating blower will continue to run. The blower will
automatically adjust its speed and turn off as the fireplace cools
down.

START UP AND ADJUSTMENTS
High Altitude
The Mantis can be installed to altitudes up to 10,000 feet in the
U.S., and up to 4,500 feet in Canada. The installation must meet
the requirements of the National Fuel Gas Code or local jurisdic-
tions.
Humidifier Operation
When the fireplace has been running, the "AUX" symbol on the
display panel (Figure 40) will turn on to signal that the pump has
been activated. Refer to Page 36 - Automatic Humidifier Opera-
tion.
Paint Curing - First Firing
The Mantis Power-Vent High-Efficiency Fireplace has been paint-
ed with the high quality heat resistant silicon paint. To ensure that
the paint is properly cured, allow the fireplace to operate with both
burners on, for approximately one hour. During the initial firing of
the appliance, it is common for smoke to appear.
CAUTION
DO NOT touch the surface of the fireplace. The paint will
soften during the initial operation, and will harden over
time. Once the paint is cured, it will not soften again.
• To prevent triggering of smoke alarms, supply proper ventila-
tion to the room where the unit is installed.
• DO NOT clean the fireplace with any caustic or abrasive
cleaning solutions. This will damage the surface.
• Any damage to the painted surfaces should be repaired only
with authorized paint available from your Mantis Dealer.
