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 (Figures 32 and 33) indica
-
tor is on.
4. Burner selection: select low burn (front burner), medium
burn (rear burner), or high burn (both burners). Low burn
switch (Figure 32) controls the front burner only. Medium
burn switch (Figure 33) 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). Be
-
fore starting ensure that the power L.E.D (Figure 34A) is on
and burner switches are off. Switch on the heater by engag-
ing the low and medium burner switch, this will activate the
pressure switch and the exhaust fan L.E.D (Figure 34E) will
be on. Also the two burner L.E.D’s (Figure 34C and 34D)
will start flashing 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 flame on the rear burner, but the burner L.E.D
is on, then there will be flame there which will become more
visible as the heater warms up. Once the heater warms up
the low speed L.E.D (Figure 34F) will light and the convec
-
tion fan will blow warm air from the heater. As the heater
becomes warmer, the medium L.E.D (Figure 34G) will come
on. When the heater has reached its highest operating tem
-
perature, all three L.E.D’s will light up and the convection
fan will now be running at its high speed. Refer to page 30
- Fan Operation. When the heater has been running for some
time, the water pump L.E.D (Figure 34B) may come on to
signal that the pump has been activated. Refer to page 33
- Automatic Humidifier 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 32)
b. Medium setting (rear burner only) - engage medium
burner switch only (Figure 33)
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 first, then turn off the front burner.
When switching from rear burner to the front burner, be sure to activate the front burner first. Simple rule - always activate the
desired burner first, 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 38 - Resetting the Heater.
