approved method. Verify that all required kits (propane gas,
etc.) have been appropriately installed.
FURNACE STARTUP
1. Close the manual gas shutoff valve external to the
furnace.
2. Turn off the electrical power to the furnace.
3. Set the room thermostat to the lowest possible
setting.
4. Remove the burner compartment door.
NOTE: This furnace is equipped with an ignition device
which automatically lights the burner. Do not try to light
the burner by hand.
5. Move the furnace gas valve manual control to the
OFF position.
6. Wait five minutes then smell for gas. Be sure to
check near the floor as propane is heavier than air,
7. If you smell gas after five minutes, immediately
follow the Saf et y Consi der at ions on page 3 of this
manual. If you do not smell gas after five minutes,
move the furnace gas valve manual control to the
ON position.
8. Replace the burner compartment door.
9. Open the manual gas shutoff valve external to the
furnace.
10.Turn on the electrical power to the furnace.
11. Adjust the thermostat to a setting above room
temperature.
12. After the burners are lit, set the thermostat to
desired temperature.
FURNACE SHUTDOWN
1. Set the thermostat to the lowest setting.
The integrated control will close the gas valve and
extinguish flame. After the blower off delay expires,
the circulator blower de-energizes.
2. Remove the burner compartment door and move the
furnace gas valve manual control to the OFF position.

Before placing a gas furnace or any gas appliance in opera-
tion, verify that the gas piping, gas fittings and all gas com-
ponents are safe and free of leaks by means of an electronic
combustible gas indicator and a gas meter dial test. Com-
bustible gas indicators must be calibrated and verified at
intervals prescribed by the instrument manufacturer.
The line pressure supplied to the gas valve must be within the
range specified in the Inl et Gas Supply Pr essur e table. The
supply pressure can be measured at the gas valve inlet pressure
tap or at a hose fitting installed in the gas piping drip leg. The
supply pressure must be measured with the burners operating.
To measure the gas supply pressure, use the following proce-

Honeywell Model VR9205R Connected to Manometer
1. Turn OFF gas to furnace at the manual gas shutoff valve
external to the furnace.
2. Connect a calibrated water manometer (or appropriate
gas pressure gauge) at either the gas valve inlet
pressure tap or the gas piping drip leg. See Honeywell
VR9205R gas valve figure for location of inlet
pressure tap.
