OPERATION
When the hydraulic thermostat
bulb "senses" the need for heat, the unit cycles
"ON" at a full input rate. The unit remains at this full input rate until the
hydraulic thermostat
bulb is "satisfied". When this happens, the burner will shut
off with the pilot flame remaining lit.
Note: The burner modulates between "ON" and the pilot flame. When the
CGR 18PT is "ON" all three ceramic plaques will "glow". There will never be a
time when only one or two ceramic plaques are "glowing".
The "LO"
and "HI" setting I_as temperature
range of approximately
55 -_F to
90 _ F, respectively.
This is the temperature
at the hydraulic thermostat
bulb, not
the room temperature.
The owner is advised to determine
the particular heat
setting that is desired for comfort, a.s heating requirements
are different for every
owner.
Attention:
If no heat is desired, turn the gas control knob to the "Pilot" position
(not to the "LO" position).
