22. Turn adjustment screw out (counterclockwise) to
decrease pressure, turn in (clockwise) to increase
pressure. Only small variations in gas fl ow should be
made by means of the pressure regulator adjustment.
In no case should the fi nal manifold pressure vary more
than plus or minus 0.3” water column from the specifi ed
nominal pressure. Any major changes in fl ow should be
made by changing the size of the burner orifi ces. The
measured input rate to the furnace must not exceed the
rating specifi ed on the unit rating plate.
23. Reset all other appliances so they function normally.
24. Turn off gas and electrical supply to the furnace, remove
the manometer hose from the pressure tap bosses, and
tighten the inlet and outlet pressure tap screws using
the 3/32” Allen wrench (clockwise 7 in-lb minimum).
25. If regulator adjustment screw (removed in step 11) is
white, the gasket supplied with the kit must be installed
on the regulator cover screw. The gasket is not required
if the regulator adjustment screw is black.
26. Replace the regulator cover screw on the regulator
sleeve.
27. Attach the kit provided WARNING label to the gas valve
where it can be readily seen. Also attach the small
round L.P. label to the top of the regulator cover screw.
28. Turn on the gas and electrical supply, energize the
appliance and recheck for leaks.
29. Observe at least 3 ignition cycles to assure quick and
smooth ignition and burner operation.
30. Reinstall the access panels.

CAUTION
TO AVOID THE RISK OF PROPERTY DAMAGE, PERSONAL INJURY
OR FIRE, SHUT OFF GAS SUPPLY FIRST, THEN DISCONNECT THE
ELECTRICAL SUPPLY BEFORE PROCEEDING WITH CONVERSION.
NOTE: Conversion instructions for the Honeywell
VR8215 gas valve begin on the following page.
17. Turn on the electrical supply.
18. Adjust the room thermostat to allow for constant operation.
19. If you have the correct manifold pressure and the
burners do not light, there may be air trapped in the
lines. Follow these instructions:
To check for air trapped in the supply line: Verify line
pressure is in the correct range. If manifold pressure is
indicated during the ignition trial, the valve is opening and
air may be in the line.
Units with hot surface ignitors: The valve will not open
until the ignitor is at the proper temperature (glowing
brightly).
Units with spark ignition: The valve will open as soon
as the spark starts. If no manifold pressure is indicated
during the trial for ignition, please return to step 13 to
ensure the correct spring was used and to ensure the
regulator adjustment is near the bottom of the adjustment
range.
20. If gas inlet pressure falls outside the range of 11” and 13”
W.C. after the unit has been in operation for 15 minutes,
adjust the gas supply pressure (not manifold pressure),
check piping size, etc., and/or consult with local utility.
NOTE: Any other gas-fi red equipment should be ON
before any adjustments are made.
21. Check manifold pressure. For propane gas, the manifold
pressure must be between 9.7” and 10.3” W.C.
WARNING
TO AVOID THE POSSIBILITY OF EXPLOSION OR FIRE, NEVER USE A
MATCH OR OPEN FLAME TO TEST FOR LEAKS.
9. Using a fl at blade screwdriver, remove the regulator cover
screw.
10. Using a fl at blade screwdriver, remove plastic regulator
adjustment screw located beneath the cover screw.
11. Remove the natural gas regulator spring from the regu-
lator sleeve.
12. Insert the kit (P/N B1880007, WR F92-0999) provided
L.P. regulator spring into the regulator sleeve.
13. Replace the regulator adjustment screw and adjust it
clockwise to bottom stop. Follow instructions below
beginning in step 21 for checking & adjustment to verify
manifold pressure falls into the desired range.
14. Reinstall the manifold/gas valve assembly into the appli-
ance. Rewire the gas valve.
15. Apply a liberal amount of pipe joint compound or pipe
thread tape to the threads and reassemble the piping
previously removed. NOTE: the pipe joint compound or
pipe thread tape must be resistant to L.P. gas.
16. Turn on the gas supply and check for leaks.
