Sequence of Operations – One Burner Only
1. The Display Panel will be energized, and the light for either
the front burner or back burner will flash, corresponding to
which burner switch is activated.
2. The inducer will activate immediately and will prove the pres-
sure switch within 16 seconds. This will initiate the ignition
sequence.
3. The igniter (HSI) will energize and start to glow red.
4. Within 3 to 5 seconds, the gas valve will open and ignite the
burner. The flame sensor will verify the flame is present within
2 to 5 seconds.
5. The igniter for the front burner will energize 5 to 7 seconds
after the flame is established on the burner.
6. As the Mantis warms up, the circulating blower will activate,
starting on Low speed. The Low Blower L.E.D. will light when
the blower turns on.
7. As the Mantis continues to operate, the speed of the circulat-
ing blower may increase.
Shut Down Instructions
To turn the fireplace off, simply push "OFF" on the remote or switch
the burner switch(es) to the "OFF" position. See Figure 56. DO
NOT cut the main electrical power to the fireplace.
The circulating blower will continue to operate after the burners
are 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 4.0 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 1/8 inch N.P.T. plugged tapping, 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 burners. In most cir-
cumstances, the circulating blower will start 3 to 5 minutes after
ignition of the burners.
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 turn off once the fireplace has cooled down.

START UP AND ADJUSTMENTS
Figure 73
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. A high altitude kit is needed for installation above 2,000 feet.
See the instructions provided with the Mantis High Altitude Kit for
derate instructions.
Humidifier Operation
When the fireplace has been running, the humidifier L.E.D.
(Figure 73) may turn on to signal that the pump has been acti-
vated. Refer to Page 47 - Automatic Humidifier Operation.
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 1 hour. During the initial firing of the
fireplace, 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.
• During initial firing of logs, an odor will occur as the logs are
curing. It is also common for the burner to burn with a yellow
flame.
• 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.
