AGAGC9NPS01B Gas Conversion Kit, Natural to Propane: Installation Instructions
13. Turn furnace gas valve switch to ON position.
14. Turn on furnace power supply.
15. Set room thermostat to call for heat.
16. Check pressure tap plug for gas leaks when main burners ignite.
17. Check for correct burner flame.
CHECK LOW GAS PRESSURE SWITCH
The newly installed low gas pressure switch is a safety device used to
guard against adverse burner operating characteristics that can result
from low gas supply pressure. Switch opens at not less than 7.2 in. w.c.
and closes at not greater than 10.2 in. w.c.
This switch also prevents operation when the propane tank level is low
which can result in gas with a high concentration of impurities,
additives, and residues that have settled to the bottom of the tank.
Operation under these conditions can cause harm to the heat exchanger
system. This normally open switch closes when gas is supplied to gas
valve under normal operating pressure.
The closed switch completes control circuit. Should an interruption or
reduction in gas supply occur, the gas pressure at switch drops below
low gas pressure switch setting, and switch opens. Any interruption in
control circuit (in which low gas pressure switch is wired) quickly closes
gas valve and stops gas flow to burners. When normal gas pressure is

restored, the system must be electrically reset to re-establish normal
heating operation.
Before leaving installation, observe unit operation through two complete
heating cycles. During this time, turn gas supply to gas valve off just
long enough to completely extinguish burner flame, then instantly
restore full gas supply. To ensure proper low gas pressure switch
operation, observe that there is no gas supply to burners until after hot
surface igniter begins glowing.
LABEL APPLICATION
1. Fill in Conversion Responsibility Label 346161-205 and apply to
Blower Access Door of furnace. Date, name, and address of
organization making this conversion are required (see
2. Attach Conversion Rating Plate Label 346161-201 to outer door of
furnace (see
Fig.

3. Attach Gas Control Conversion Label 346161-202 to gas valve. Do
not use 346161-203, which is similar.
CHECKOUT
1. Observe unit operation through two complete heating cycles.
2. See Sequence of Operation in furnace Installation, Start-Up, and
Operating Instructions.
3. Set room thermostat to desired temperature.
