To Turn Appliance Off
1. Set the thermostat to the lowest setting, then move lever to
“OFF” position.
2. Turn off all electrical power to the appliance if service is to be
performed.
3. ALL furnaces have a 12 volt switch built on the furnace and must
be turned “ON” for furnace to operate. Some models may have a
wood panel cover in front of switch, making it difficult to have
access to it.
External Vents. Always be sure these vents are clear of any
objects like screens, duct tape, etc., BEFORE OPERATING.
Ducting. Wall or floor registers, and return air grills MUST be
kept clear of any obstructions. Any such restrictions will prevent the
furnace from correct operation. Closeable registers will reduce air
flow. Never shut registers off completely, possibly causing furnace to
limit out and shut down.
Propane pressure, as defined in Chapter Four - Systems, is
extremely important. A dial gauge or U-tube manometer is required
to perform tests and adjustments. Pressure must be set at 11 inches
w.c. (water column) plus or minus 1/2 inch. Incorrect gas pressure
can cause any appliance to operate inconsistently and cause poor
combustion. Only qualified technicians with proper training and
equipment should make any mechanical adjustments.
Voltage must be between 10.5 volts to 13.5 volts at the furnace
during operation. Below 10.5 volts the furnace will shut down. Both
high and low voltage places excessive wear on the motor and
brushes.
Any mechanical adjustments, such as electrode adjustments, should
be performed by a qualified service technician.
Do not install screens over the vents for any reason. Screens will become
restrictions causing unsafe or inefficient operation.
