Install location:
The R-Series replace may be installed in any location that maintains
proper clearances to air conditioning ducts, electrical wiring, and
plumbing. Safety, as well as efciency of operation, must be considered
when selecting the replace location. Try to select a location that does
not interfere with room trafc, has adequate ventilation, and offers
an accessible pathway for Power Vent installation.
Basic Operation:
The gas control components of this replace are located in the bottom
of the rebox below the burner system. All models are supplied with
a Honeywell smart valve gas control and do NOT have a variable
ame control. There are two air switches that control the gas control
system, located in the bottom of the rebox. These gas valves and
pressure switches communicate with the electrical control panel
through a six conductor cable supplied with the replace.
To operate the replace, Montigo supplies 20' of low voltage wire
from the electrical control panel. Connect the two wire harnesses
to a standard single pole ON/OFF switch to the location of your
choice. You may extend these wires up to 100' in length with a wire
of equal quality.
