LEGEND:
NG = Natural Gas LP = Liquid Propane 1 = CRLPELEV001A00
* As the height above sea level increases, there is less oxygen per cubic
ft. of air. Therefore, heat input rate should be reduced at higher altitudes.
2 = CRLPELEV002A00
3 = CRLPELEV003A00
{
Not included in kit. May be purchased separately through dealer. 4 = CRLPELEV004A00
Minimum heating entering air temperature
When operating on first stage heating, the minimum
temperature of air entering the dimpled heat exchanger is
50
_
F continuous and 45
_
F intermittent for standard heat
exchangers and 40
_
F continuous and 35
_
F intermittent for
stainless steel heat exchangers. To operate at lower
mixed--air temperatures, a field--supplied outdoor--air
thermostat must be used to initiate both stages of heat
when the temperature is below the minimum required
temperature to ensure full fire operation. Wire the
outdoor--air thermostat (part no. HH22AG106) in series
with the second stage gas valve as shown below. Set the
outdoor--air thermostat at 35
_
F for stainless steel heat
exchangers or 45
_
F for standard heat exchangers. This
temperature setting will bring on the second stage of heat
whenever the ambient temperature is below the thermostat
setpoint. Indoor comfort may be compromised when
heating is initiated using low entering air temperatures
with insufficient heating temperature rise.
