LIGHTING INSTRUCTIONS
1. Main Electrical power supply must always be switched on to
the unit with the two burner switches in the off position (up)
before lighting the heater.
2. Turn on main gas supply.
3. Verify that main electrical supply is switched on by
checking the 115V AC power status display (Figure 57)
indicator is on.
4. Burner selection: select low burn (front burner), medium
burn (rear burner), or high burn (both burners). Low burn
switch (Figure 59) controls the front burner only. Medium
burn switch (Figure 58) controls the rear burner only. When
both switches are down, they will activate both the low and
medium burners, which is the high setting.
5. Heater operating LED sequence (Front Display Panel).
Before starting ensure that the power L.E.D (Figure 60A)
is on and burner switches are off. Switch on the heater by
engaging the low and medium burner switch, this will ac-
tivate the pressure switch and the exhaust fan L.E.D
(Figure 60E) will be on. Also the two burner L.E.D’s
(Figure 60C and 60D) will start ashing for 35 seconds
prior to ignition. Once both burners have ignited, the burner
L.E.D’s will remain on. If you can’t see ame on the rear
burner, but the burner L.E.D is on, then there will be ame
there which will become more visible as the heater warms up.
Once the heater warms up the low speed L.E.D (Figure 60F)
will light and the convection fan will blow warm air from
the heater. As the heater becomes warmer, the medium L.E.D
(Figure 60G) will come on. When the heater has reached its
highest operating temperature, all three L.E.D’s will light up
and the convection fan will now be running at its high speed.
Refer to Page 41 - Fan Operation. When the heater has been
running for some time, the water pump L.E.D (Figure 60B) may
come on to signal that the pump has been activated. Refer to
Page 41 - Automatic Humidier Operation.
Note: Three heat settings are available for operating your Mantis
heater - low, medium and high.
a. Low setting (front burner only) - engage low burn switch
only (Figure 58)
b. Medium setting (rear burner only) - engage medium
burner switch only (Figure 59)
c. High setting (front and rear burners).
Caution: When switching from the front burner to the rear burner, be sure to activate the rear burner rst, then turn off the front
burner. When switching from rear burner to the front burner, be sure to activate the front burner rst. Simple rule - always
activate the desired burner rst, then switch the other burner off. If it is switched the wrong way, the burner(s) will go out
and the heater may need to be reset. Refer to Page 50 - Resetting the Heater.
