Removal of Metal Screen Inserts
a) Remove entire burner box assembly, including
burners, from the partition panel as one unit.
b) Hold assembly and remove the screen retention
plate and tube inserts from each section of the
heat exchanger.
c) Reinstall the retention plate and entire burner box
assembly.
5. Reinstall the gas manifold and reconnect the gas
valve low voltage wiring. Install new wire ties mak-
ing sure that wires do not droop between orifices
and burners.
NOTE: To prevent unsatisfactory unit operation, the
proper gas conversion kit must be used for each gas
valve. Use the White-Rodgers kits only with the White-
Rodgers gas valve, and use the Honeywell Spring kit
only with the Honeywell gas valve. THE SPRING KITS
ARE NOT INTERCHANGEABLE.
NOTE: Two stage furnaces do not require a spring kit.
Discard all spring kits.
6. On single stage furnaces, replace the gas valve
regulator spring with one of two new springs in-
cluded in this propane conversion kit. If the unit is
equipped with a White-Rodgers 36E (except 36E96)
gas valve use Spring Kit #92-0659. If the unit is
equipped with a Honeywell VR8205 or SV9500 gas
valve use Spring Kit #393691-4. In each case,
change the regulator spring per instructions included
with that particular regulator spring. Discard unused
spring kits.
7. Leak check orifice threads using a soap solution.
WARNING
PERSONAL INJURY HAZARD
To prevent death, personal injury or
property damage due to fire or explo-
sion, do not use a flame to check for
leaks.
8. The position of the ignitor, relative to the burner, is
not affected by this conversion procedure but the
ignitor should be visually inspected for any damage
at this point. Reinstall the burner box cover.

NOTE: To prevent premature heat exchanger failure,
follow the instructions below to remove all metal inserts
from the heat exchanger tubes during propane conver-
sions.
3. PGB**C and PGD**C models only: Remove pilot
tube from gas valve. Remove the screws holding
the pilot assembly to the burner tray and remove
the assembly. Remove the pilot orifice as shown in
Figure 3. Replace the pilot orifice with the orifice
provided with the kit, and reassemble in reverse
order.

WARNING
PERSONAL INJURY HAZARD
All metal inserts, screens or turbulators
must be removed from the heat ex-
changer tubes when using propane gas.
Failure to comply could cause serious
personal injury or death. Failure to com-
ply with this requirement will also void
warranty coverage.
4. Remove metal screen inserts from the entrance of
the heat exchanger tubes. See Figure 4 and follow
the a,b,c directions. Some models do not have
metal screen inserts.
